HP StorageWorks XP24000/XP20000 Disk Array

The XP24000 and XP20000 also decrease the costs and complexities of data management with a broad portfolio of software. Through thin provisioning, organizations can reduce power and cooling costs by supplying storage capacity to applications from a virtualized pool and reducing unused storage that consumes power, requires cooling, and takes up space. As a virtualization platform, the XP enables important functions such as heterogeneous data migration, array repurposing, and storage tiers. The XP also eliminates contention for valuable storage resources through array partitioning. Partitioning enhances the success of storage consolidation efforts by assigning array resources to certain applications and administrators. And by consolidating multiple hosts running diverse operating systems to an XP, you can reduce the time it takes to manage diverse environments and simplify the implementation of backups and disaster recovery solutions.

Additionally, with thin provisioning automatically allocating resources when needed and the XP's ability to scale seamlessly, you'll be able to accelerate the growth of your business. With an XP disk array, you can feel confident that the business information your people need is available to them-wherever and whenever they need it.

Boot the XP24000/XP20000 once and never worry about it going down

When operating a business that demands constant uptime, the risk of data loss or downtime is always at the forefront. That risk is mitigated with the XP24000/XP20000. All components are redundant, hot-swappable, and can be upgraded online, including: disk drives, processors, I/O interfaces, power supplies, batteries, fans, and control processors, to provide extreme reliability and availability. Additionally, the XP24000/XP20000 can upgrade firmware one microprocessor at a time, so no downtime is experienced.

Redundant data paths ensure that there is no single point-of-failure, minimizing the likelihood of unplanned shutdown. If one of the two data paths fails, the other path takes over automatically. You are then alerted to the problem, and can fix it quickly with a minimum of stress because the data is still accessible while the problem is being addressed.

Configurations that provide continuous access to your data despite disaster

After the August 2003 Northeastern North America blackouts, 93% of the companies that lost their data center for more than ten days filed for bankruptcy within a year.¹

If you experience a large-scale disaster, you need to not only have high levels of data protection but also business continuance. Maintaining operations in times of crisis can mean the difference between the continued success of business and its failure. In addition to the protection built-in to the XP24000/XP20000, HP offers various products and solutions around the XP24000/XP20000 for your ultimate protection.

HP StorageWorks XP Continuous Access Software provides reliable array-to-array replication for the most demanding requirements. The remote replication capability provided by XP Continuous Access provides assurance that even if access to a site is lost, the business can continue operations by using the storage systems and data located at another site. Replication solutions, such as XP Continuous Access Journal, can save money on telecommunication costs and improve availability. XP Continuous Journal allows the link between sites to be sized for the average I/O rate rather than for the peak I/O rate, resulting in large telecommunication cost savings.

HP StorageWorks XP Cluster Extension clustering solutions allow remote replication to be tightly integrated with high availability server clustering to provide true multi-site server/storage disaster recovery. XP Cluster Extension with the XP24000/XP20000 offers disaster tolerance against application downtime from fault, failure, or site disaster by extending clusters between data centers. It resurrects your critical applications at a remote site within minutes after an event. XP Cluster Extension works seamlessly with your open-system clustering software, XP Continuous Access and your XP24000/XP20000 storage system to automate fail-over and fail-back between sites making your business Disaster Proof.

HP Metroclusters with XP Continuous Access seamlessly integrates the XP24000/XP20000 disk array remote replication capabilities with HP Serviceguard on HP-UX. It provides automatic and bi-directional failover/failback of business critical data and applications between data centers.

HP Continental Cluster Software provides the highest levels of disaster tolerance by eliminating the cluster itself as a single point of failure. It uses data replication technologies to provide application recovery across multiple widely-separated HP-UX Serviceguard clusters. The HP Continental Cluster product provides the ability to monitor a Serviceguard cluster and recover mission critical applications to a remote Serviceguard cluster, should the monitored cluster become unavailable or if there is a disaster at the cluster site.

The 3 Data Center Solution (3DC)
A 3 Data Center Solution allows you to keep your business online, no matter what happens. XP disk arrays on two sites replicate data synchronously, while the XP on a third site many miles away protects against a regional disaster that hits the first two. Lose any one site and the other two keep going. Implementation of the 3DC solution combines the data consistency of synchronous replication and the long-distance capability of journal replication to protect against local and wide-area disasters. This technology provides other benefits, including:

• Maintaining high performance: Using synchronous replication over a short distance in a campus or metropolitan area cluster provides the highest level of data currency without significant impact to application performance.
• Permitting swift recovery: Campus/metropolitan cluster implementation allows for fast automated failovers after a local area disaster occurred.
• Eliminating transaction loss in the case of localized disasters caused by synchronous replication implementation.
• Permitting recovery even when a disaster exceeds traditional regional boundaries or extended duration: A wide-area disaster could disable both data centers 1 and 2, but with some manual interaction operations can be shifted to data center 3 and continue unaffected by the disaster.
• Staffing the remote data center with people living outside the disaster area: A wide-area disaster affects people located within the disaster area, both professionally and personally. By moving operations out of the region to a remotely located recovery data center, operational responsibilities shift to people not directly affected by the disaster.

External Storage Disaster Recovery
With this feature, you can take the disaster recovery benefits of an XP to any other array from any vendor. An exact, synchronous copy of an XP volume is replicated to a heterogeneous array located at a second site. This second site can be used for manual disaster recovery in the event that the primary site becomes unavailable.

By using this 2-site DR solution to synchronously copy data from an XP to an external storage device, you can now implement a lower cost disaster recovery plan by utilizing arrays you already have.

You can use this solution with business critical applications such as email, billing, or data warehouse applications where it is important to have a backup copy of the latest data that can be put back online in a matter of hours by connecting the server to the second array.

Using External Storage Disaster Recovery allow s you to 1) implement disaster recovery functionality at a fraction of the cost of other solutions, 2) redeploy existing arrays in a new disaster recovery solution, and 3) enjoy the green effect of using storage resources efficiently.

Protect against data loss with built-in safety measures

Relax, knowing that data is protected. If power goes out, the XP batteries can continue operations and then write cache data to disk. RAID 6 adds an extra layer of fault tolerance. Continuous Track checks your XP for unseen issues, and the end-to-end checksum confirms data integrity from port to disk and back.

Battery DeStage Mode

The XP gives you two ways to protect your data if you experience a power outage.

• Battery back-up mode: Fast restart with battery backup mode that protects Cache and Shared Memory for at least 36 hours. This mode works for both the XP24000 and XP20000.
  
• De-stage mode: De-stage mode keeps the entire system running for 1 min and then flushes Cache to final destination disk. This mode works only on the XP24000.
  

RAID 6 Configuration

Protect your data even if two disk drives fail at the same time in a parity group! The XP24000/XP20000 redundancy is further enhanced through a RAID 6 (6D+2P) configuration that allows up to two disk drives out of eight to fail and still maintain data availability. RAID 6 uses block level striping and two independently calculated distributed parity blocks across 8 disk drives. RAID 6 is an excellent combination of performance, extra redundancy, and storage efficiency.

Continuous Track

With the rapid increase of e-commerce, data warehousing, and data mining, storage has become a strategic resource within an enterprise. Businesses must access their data instantly and continuously. The criticality of data availability dictates that the storage systems must be up and running all the time. IT departments need the ability to continuously monitor their storage services and resolve their problems proactively and immediately.

With leading diagnostic technology, HP StorageWorks Continuous Track provides 24 x 7 around-the-clock worldwide service capabilities for the XP24000/XP20000 to achieve the highest level of availability. Continuous Track utilizes HP's Instant Support Enterprise Edition (ISEE), a proactive, remote support service that provides the highest level of support services available anywhere. This market-leading support capability is designed to provide a single, secure interface into your data center to deliver proactive, reactive, and multi-vendor environment support services for your entire IT infrastructure.

Continuous Track with ISEE allows the XP disk array to be continuously monitored 24 hours a day by expert systems and engineers at HP Response Centers over either a phone line or the internet. Service events are reported instantly. Hardware failures are detected immediately. Potential problems can be investigated and resolved proactively by HP engineers before your business is affected. The Continuous Track support service substantially eliminates unplanned downtime and increases the availability of storage, applications, and data access.

End-to-end Checksum

The XP24000/XP20000 end-to-end checksum feature is used when moving data from cache to disk. It protects data against corruption while it is in transit inside the array and confirms data integrity from port to disk and back.

Decrease exposure to data loss through the security features of XP Array Manager Software

HP StorageWorks XP Array Manager Software protects your data by controlling access, preventing unauthorized alteration, and securely deleting data when it is no longer required. Configure security to prevent unauthorized servers from accessing the data. Protect the XP Disk Array from accidental modification by setting up partition administrators who only have access to the partition. Control access to critical data, for purposes such as archiving and data retention. Set read and write access permissions, create read-only volumes, and protect data from being replicated. And when the data is no longer needed, securely delete it with successive overwrites to minimize the likelihood that it can be restored.

Protect your data from falling into the wrong hands

The XP hardware provides encryption capabilities with the optional Enhanced Disk Adapter (DKA) offering. The Enhanced DKA encrypts the data on disk drives so that data cannot be read off a disk drive that is removed from the XP disk array. Only data on the disk drives is encrypted (data in cache is not encrypted).

Reduce environmental impact and accelerate application deployment

XP Thin Provisioning Software

Through XP Thin Provisioning, organizations can reduce storage costs. As an IT manager, you can now configure all the capacity you will need for the future, but only buy what you need today. XP Thin Provisioning will automatically allocate capacity as applications need it.

HP StorageWorks XP Thin Provisioning Software allows you to supply disk storage capacity to your applications from a pool of virtualized storage. By enabling you to allocate your anticipated future storage capacity needs from virtual disk storage, HP XP Thin Provisioning Software reduces the amount of physical disk capacity initially required. As utilization of physical disk space increases over time, you can purchase more disk capacity as it is needed, and install it without affecting your applications. By removing the guessing from capacity planning, HP XP Thin Provisioning reduces the cost of volume management. By using XP Thin Provisioning, you can lower power and cooling costs by supplying storage capacity to applications from a virtualized pool and reducing unused storage that consumes power, requires cooling, and takes up space.

7.2K Disk Drives

Disk drives with 7.2K rpm address the need for businesses to cost-effectively store infrequently accessed information in a more economical fashion and with performance that is faster than traditional tape. 7.2K drives on an XP offers you a higher capacity/lower cost per gigabyte and more energy efficient option compared to the 15K/10K disk drives, thereby providing a cheaper tiered storage solution within the array.

Solid State Disk Drives (SSDs)

Because a single SSD drive could potentially replace numerous spinning, Fibre Channel (FC) drives to achieve the same performance level, SSD drives will consume less power and generate less heat than compared to implemented Fibre Channel drives.

In addition to power savings, SSDs will generally require less physical space than FC drives since one SSD can likely replace multiple FC drives. A single SSD drive could replace upwards of 30 FC disk drives. This reduction in FC drives then also gives you a smaller physical footprint in the data center.

By using SSD disk drives, 7.2K disk drives, and XP Thin Provisioning Software, you can enjoy the green effect of reduced floor space, reduced power usage, and reduced cooling requirements in your data center.

Reduce costs and simplify management of multi-vendor storage

Simplify data management in a complex, multi-vendor environment. Virtualization enables important functions such as data migration, array repurposing, and storage tiers. XP External Storage Software virtualizes heterogeneous disk arrays, so that hosts see the capacity, but not the physical attributes of the external storage devices.

The XP24000/XP20000 simplifies the management of heterogeneous SAN environments through its ability to support up to 247 PB/ 96 PB respectively of external storage-all configured 'behind' a single XP. XP External Storage software uses advanced virtualization technology to allow storage administrators to host XP Disk Array LUNs on externally attached disk arrays. Any Fibre Channel port from any CHA pair installed in any slot can be used to connect to external storage.

Instead of seeing a confusing collection of dissimilar arrays, host systems perceive all the data to be stored inside the XP disk array. In effect, the XP becomes the storage controller for a flexible, multi-tiered collection of storage with a range of cost and performance capabilities. By configuring current or legacy storage systems behind a single XP24000/XP20000, data can be moved back and forth dynamically across tiers, all of which is invisible to the applications.

The XP's virtualization feature also reduces the total cost of storage ownership by:

• Exploiting common storage management across multiple vendors' systems
• Easily deploying a dual-vendor policy
• Facilitating simpler and lower cost data migrations
• Increasing storage utilization
• Extending the life of legacy storage

Supported arrays include the HP StorageWorks MSA family of low-cost arrays, the HP EVA disk array family, the HP XP disk array family, and many current and legacy arrays from other storage providers, including EMC, IBM, and HDS.

• For a complete/up-to-date list of supported arrays and accompanying firmware versions, please contact your HP representative.

Make certain your critical applications have the resources they demand with partitioning. The dynamic partitioning solution prevents inadvertent administrator errors from affecting the entire array and allows storage consolidation, even when you have applications that can't tolerate performance loss, by allocating XP resources to individual hosts or departments.

As businesses strive to improve operational efficiency, consolidation of servers and storage becomes an attractive option. Partitioning enables storage administrators in large consolidated storage environments to host multiple diverse user groups on one XP while maintaining appropriate isolation between applications. Partitioning allows storage administrators to subdivide a large XP disk array into smaller independently configured and managed storage segments. Applications that would normally compete for resources can share a single disk array without impacting each other. Departments can share a single disk array confident that administrators cannot affect portions of the disk array that belong to someone else.

The XP24000 can be divided up into 32 partitions, while the XP20000 can be divided up into 16 partitions. Partitions can be dynamically reconfigured as needs change.

Standardize and simplify storage through consolidation

Simplify your operations and reduce costs by consolidating multiple applications onto a single XP disk array. By having multiple hosts running diverse operating systems connected to an XP, you can reduce the time it takes to manage various environments and simplify the implementation of backups and disaster recovery solutions.

By consolidating multiple SANs into a single XP disk array, four important functions can happen:

1. Backups can be done using a simpler framework and common devices
2. Administration of the total environment can be done with a single set of software
3. Buffer storage for growth can be consolidated and allocated to the hosts as needed. The amount of idle storage awaiting allocation can be reduced. The customer saves money by postponing purchases through minimized waste.
4. With all the enterprise storage consolidated into a single array, the user can implement Disaster Recovery solutions in a much easier and less expensive fashion.

These above four areas are some of the key drivers that make storage consolidation a primary way to reduce costs in the data center.

Supported Hosts - A wide variety of servers and operating systems can be connected to an XP24000/XP20000 disk array, including:

• HP-UX
• Microsoft Windows
• IBM AIX
• Sun Solaris
• VMware
• LINUX - IA2, Red Hat
• HP OpenVMS
• HP Tru64 UNIX
• HP NonStop
• Mainframe

For more details on which servers and operating systems are currently supported, please contact your resellers and your HP technical support to review the supported server and operating system information.

React quickly to new business demands

Thin provisioning also provides the flexibility you need to respond quickly to new demands. You can now configure all the capacity you will need for the future, but only buy what you need today. XP Thin Provisioning will automatically allocate capacity as applications need it.

HP XP Thin Provisioning Software simplifies and accelerates storage provisioning by allowing you to create volumes without the need for physical installation and formatting time. Because your applications only see the virtual capacity that is allocated to them, there is no need for downtime when you install new physical disk capacity. And with simplified storage provisioning, you will be able to manage your storage with confidence knowing that the risk of human error has been reduced.

Accelerate your return on investment and enhance storage consolidation by using the virtualized storage pool to deploy more applications and servers per storage system. Deploy your applications faster because HP XP Thin Provisioning Software makes it easier to plan and size storage.

Thin provisioning pools can also be located on external storage devices, adding another virtualization element to the XP disk array.

Start with the configuration you need today and add additional capacity as your needs change

The CIO dilemma of either overbuying capacity today or planning for a costly "forklift" upgrade tomorrow is now history. The XP24000 can scale from 9 to 1152 disk drives. The XP20000 scales from 0 to 240 disk drives. And all main components like host ports and cache can be added--without shutting down critical operations. Simply buy what you need today and grow as your needs change.

The charts below highlights the XP24000 and XP20000 scalability:

Your round-the-clock environment demands the ultimate in performance to deliver critical data at break-neck speed.

In the fall of 2008, HP announced a new world record SPC-2 result of 8.7GB/s. This result was achieved on a single XP array using 265 Hard Disk Drives (HDDs). HP eclipses the next closest single array result by more than 2x. In fact, this result surpasses the previous overall record that was produced by a system of 16 storage arrays and 1,536 disks by 20 percent.

SPC-2 is a benchmark of the Storage Performance Council (SPC), which measures performance on serial workloads such as streaming media, business intelligence queries, and backups. It is the only standard, audited benchmark for this kind of workload in the storage industry. Coupled with SPC-1 benchmark result of 200,000 Input/output operations Per Second (IOPS) in 2007, the HP SPC-2 result clearly establishes the HP StorageWorks XP24000 as a world leader in storage performance.

The SPC is an industry consortium chartered to provide standard, audited benchmarks to help storage customers evaluate the performance of competing storage products.

To read more about the XP24000's SPC-2 result, please visit the SPC-2 web page at http://www.storageperformance.org/results/benchmark_results_spc2. The full report is found at http://www.storageperformance.org/results/b00035_HP-XP24000_SPC2_full-disclosure.pdf.

Have the flexibility you need to meet your performance and availability objectives

The granular design of the XP24000 gives flexibility to customize for your particular need. The XP24000 can have 224 FC, 112 FICON, or 112 ESCON connections, or a mixture of each, while the XP20000 can have 48 FC, 24 FICON, or 24 ESCON connections, or a mixture of each. RAID types can be mixed to achieve performance or efficiency. And, tiered storage of different disk drive speeds and external storage devices gives you the flexibility to tune capacity and manage system costs.

Disk Controller (DKC)
The DKC consists of :

• DKC box in which the channel adapters (CHAs), disk adapters (DKAs), cache memory adapter (CMA), shared memory adapter (SMA), and cache switches;
• The HDU box in which disk drives are installed; and
• The power supplies and battery boxes that supply power to the components above.

The control unit in the DKC is equipped with a Service Processor (SVP), which is used to service the subsystem, monitor its running condition, and analyze faults. Connecting the SVP with HP StorageWorks Continuous Track enables remote maintenance of the subsystem.

Disk Unit (DKU)
The DKU consists of the four HDU boxes in each of which 64 disk drives can be installed. Each DKU can hold up to 256 disk drives and have redundant power supply systems and cooling fans included. Battery boxes that supply power to the disk drives are also held in the DKUs.

The XP20000 hardware consists of a primary rack that will hold up to 120 disk drives. This primary rack also contains the control panel, service processor (SVP), Cache Memory, Shared Memory, Crossbar Switch, Batteries, Channel Adapters (CHAs) and the Disk Adapters (DKAs). A second rack can be added that can hold up to 120 more disk drives.

A full complement of software tools is available for managing the XP24000/XP20000, and to enable a wide range of high availability solutions. The XP24000/XP20000 also provides local and remote replication capabilities for the IBM eServer zSeries and for IBM z/OS, z/VM and VSE environments.

• Exchange workloads

The XP24000 and XP20000 disk arrays also supports the following 7.2K rpm disk drives:

• 1 TB 7.2K rpm dual ported
• 2 TB 7.2K rpm dual ported

The 7.2K drives offer a higher capacity/lower cost per gigabyte option compared to the 15K/10K disk drives. This provides a cheaper tiered storage solution within the array.

With the attractive low cost and high capacity points of 7.2K disk drives, it is important to understand the appropriate applications where 7.2K disk drives should be used. Proper usage will lessen the probability of drive failure.

7.2K disk drives are designed for non-mission critical, lower duty cycle applications that are "near on-line" or infrequently accessed, such as:

• data replication for back-up
• email archives
• medical records
• imaging archives
• financial compliance archives
• test environments

These drives, with their 4Gb/s FC interface, address the need for businesses to cost-effectively store infrequently accessed information in a more economical fashion and with performance that is faster than traditional tape.

NOTE: 15K/10K and 7.2K disk drives should not be used together when doing Business Copy, Continuous Access, or Thin Provisioning. For example, in the case of Thin Provisioning, you should only use 7.2K disk drives in virtualized pools where the entire virtualized volume is made up of 7.2K disk drives.

Software ideally suited with 7.2K disk drives

• HP StorageWorks XP Tiered Storage Manager Software
  XP Tiered Storage Manager allows you to non-disruptively migrate data between tiers of storage while your applications remain on line. Using this software will simplify the creation of new storage tiers when the 7.2K drives are implemented. XP Tiered Storage Manager Software is a plug-in application for XP Command View Advanced Edition Software.
• HP StorageWorks XP Auto LUN Software
  XP Auto LUN Software provides automatic monitoring and load balancing for your XP Disk Arrays. AutoLUN allows you to move high-priority tasks to underutilized volumes, replicate volumes for backup and recovery, and view the health of your arrays. It also proposes a migration plan and even estimates how much your storage performance will improve when it's done. Using this software in combination with the 7.2K drives will allow you to make migration decisions based on disk array performance criteria.
• HP StorageWorks XP Business Copy Software
  XP Business Copy Software is a local replication solution that provides data copies within a single XP Disk Array. Using Business Copy, you can do disk-to-disk backups to the 7.2K drives and use those backups for testing, archiving, etc. Backing up to 7,2K disks provides a cheaper alternative per gigabyte than traditional backup to 15K/10K disks.

The XP24000/XP20000 disk arrays also support Solid State Disk Drives (SSDs). These disk drives are designed for applications that require the ultimate performance and speed. SSDs can be utilized as a high-performance storage tier for applications that need very low latency/high IOPs. Examples of applications that might require this extremely high performance are:

SSD Use Cases

SSD drives are best utilized with low write-intensive applications and latency sensitive environments. You'll see the best performance in environments with many random read cache misses (the XP cache already reduces the response time for writes and sequential reads/writes accesses).

Some instances where SSDs may improve performance are:

• Database and file system metadata (journals, indexes, directories, etc)
• Online Transaction Processing (OLTP)
• Cluster metadata (locks, logs, etc)
• Content caching for near Static data file/web servers
• Real time data processing
• Hypervisor running a large number of virtual machines
• Virtual Desktop Infrastructure solutions
• CAD/CAM
• 3D animation / rendering
• Contextual web advertising
• Data Modeling
• Seismic data processing
• Business Intelligence and Data mining

The SSD drives supported on the XP disk arrays are:

• 73 GB 4 Gb/s SDD
• 200 GB 4 Gb/s SSD
• 400 GB 4 Gb/s SSD
  

Solid State Disk drives can be implemented on your XP24000/XP20000 using any RAID type that is supported on any other drives today. In addition, any XP software can also be used on the SSD drives, including the popular XP Thin Provisioning Software.

The XP24000 can support up to 128 SSD drives with a max of 8 SSDs on a FC-AL loop. .

The XP20000 can support a total of 32 SSD drives.

The XP24000 can have up to 14 pairs of CHAs.*
The XP20000 can have up to 3 pairs of CHAs.

CHA pairs available for use in the XP24000/XP20000 include:

• 8 and 16 port 4 Gbps auto sensing Fibre Channel**
• 8 port 8 Gbps auto sensing Fibre Channel**
• 8 port ExSA Channel (ESCON compatible)
• 8 port 4 Gbps auto-sensing FICON in both short-and long-wave versions

* Up to 8 CHA pairs if 4 DKA sets are installed.
** The standard optical transceiver (small form-factor pluggable [SFP]) on the Fibre Channel CHAs is short-wave. Long-wave SFP transceivers can be ordered individually. A single Fibre Channel port can be quickly converted from short-wave to long-wave by swapping a short-wave SFP transceiver for a long-wave SFP transceiver. 4Gbps and 8 Gbps long-wave transceivers are available.

Enhanced DKA

The XP hardware provides encryption capabilities with the optional Enhanced Disk Adapter (DKA) offering. The Enhanced DKA encrypts the data on disk drives so that data cannot be read off a disk drive that is removed from the XP disk array. Encryption can be enabled on a Parity Group basis. Only data on the disk drives is encrypted (data in cache is not encrypted).

An XP disk array can house both an encrypted and non-encrypted DKA at the same time; however, only the data that sites behind the Enhanced DKA set is protected. XP Auto LUN software can be used to move data between encrypted and non-encrypted Parity Groups.

Only one encryption key is needed for the entire XP array. The encryption key is randomly generated by the XP when encryption is enabled for the first time. The encryption key can be backed up to the Remote Web Console computer using a KEK (Key Encryption Key).

It is important to note that utilizing this encryption feature does not change the performance of XP, as data is encrypted at the hardware (DKA) level and not at the cache.

The XP24000 supports up to 512 GB of Cache while the XP20000 supports up to 128 GB of Cache. Cache Memory is used to temporarily store data from the host until it is written to disk, or to stage data requested by the host from the disk. The XP24000/XP20000 Cache Memory modules are installed on Cache Memory Adapters (CMA):

• The basic CMA pair supports up to 16 sets of Cache modules (up to 128 GB).
• The optional additional CMA pair supports up to 16 additional sets of Cache modules (up to an additional 128 GB).

The Cache is configured as two sets of memories, onto which data that is to be written on the disk is mirrored, so the data will not be lost even if a Cache failure occurs.

Cache Partitions
XP Cache can also be allocated to particular host/port combinations to ensure that those hosts/ports enjoy optimized performance of Cache-oriented I/O. These cache partitions are assigned to specified disk array groups. Up to 32 partitions of at least 4GB can be created in an XP24000 or XP20000*. Assigning cache in this way provides another method for tuning performance for data access for performance critical applications. Cache can be partitioned separate from storage partitions.

Batteries
The XP24000 has two different kinds of batteries 56V & 12V

• 12V batteries backup Cache and Shared Memory
• 56V batteries supply power to disk drives
• 12V batteries backup data in Cache and Shared Memory for at least 36 hours
• 56V batteries are only required for De-Stage Mode*
  • De-Stage Moe will continue array operations for 1 minute uninterrupted operation, then will move all data to disk

*The De-Stage mode is only available on the XP24000.

For increased uptime, productivity and ROI -HP Care Pack packaged services for Storage
These days, you need to get the most out of your storage investment-you can't afford not to. When you buy HP storage products and solutions, it's also a good time to think about what levels of service and support you may need. To help take the worry out of deploying, designing, maintaining, and managing your environment, we've designed a portfolio of service options that are as: flexible, reliable and scalable as your storage. Unlike storage-only vendors, we take a holistic approach to your entire environment, bridging storage, servers, blades, software and network infrastructures with our HP Care Pack packaged services for Storage.

Protect your business beyond the warranty

When it comes to robustness and reliability, standard warranties on today's computing equipment have matured just as the technologies have matured. Good news on some fronts-but also a source of potential problems and subsequent consequences that come from depending on standard warranties alone. Standard warranty protects against product defects and some causes of downtime- but not the business. By using a standard approach to warranty uplifts, such as HP Care Pack Services, you can reduce downtime risks and be more certain of operational consistency for both mission-critical and standard business computing. Simply put, HP Care Pack Services normalize the warranty of combined products - helping you proactively guard against unplanned downtime.

Extending warranties with HP Care Pack Services
For cost-effective upgrading or extending your standard warranty, HP Care Pack Services offer a suite of standard reactive hardware and software support services that are sold separately, or combined as with our Support Plus and Support Plus 24 services. The portfolio also provides a combination of proactive and reactive services, such as Proactive 24 Service and Critical Service. In addition, with HP Proactive Select we offer an innovative approach to service delivery that gives you the flexibility to acquire the specific proactive services you need today, then add services as your needs evolve. HP Proactive Select offers a broad set of technical or per-event type service options - including server, storage, and network, SAN device, and software, environment, installation and education services. Services that you can mix and match depending on your specific requirements, from preliminary planning and equipment delivery to installation, configuration, integration, and testing, through every level of ongoing support. Our HP Care Pack packaged services for Storage assures help when you need it most. And for many products, post-warranty HP Care Pack Services are available when your original warranty has expired.
