| Q1. |
What is the advantage of the XP10000 over other high end arrays on the market? |
| A1. |
The XP10000 leads the market in reliability, high availability, scalability, and performance. The availability features of the XP10000 such as fully mirrored cache and redundant hot replaceable everything are unsurpassed. The XP10000’s cache centric architecture provides outstanding IOPs and sequential throughput in a broad range of real-world applications including online transaction processing (OLTP) and data warehousing. The ability of the XP10000 to perform very well in a diversity of applications and to support every major operating system makes it an excellent solution for storage consolidation. |
 |
| Q2. |
What is different between an XP10000 and an XP128? |
| A2. |
Significantly improved peak performance, scalable to 240 disk drives with 120 drives in the primary DKC rack, external storage capability, and online firmware update with no host port interruption. The XP10000 adds other XP12000 features such as External Storage XP, Disk/Cache Partitioning, enhanced Continuous Access Journal, and enhanced multi-site disaster tolerance. |
|
| Q3. |
What is different between an XP10000 and an XP12000? |
| A3. |
Maximum capacity, performance, and cost. The XP10000 scales to 240 disks with 48 host ports; the XP12000 scales to 1152 disks and 224 host ports. The XP10000 is lower in both cost and performance compared to the XP12000. The XP10000 and XP12000 run the same firmware and have the same functional features. |
|
| Q4. |
The XP disk arrays have been described as a “monolithic,” or “mainframe,” or “frame-based” disk array. EVA arrays have been described as a “modular” or “rack-based” disk arrays. What are the proper descriptions for these arrays? |
| A4. |
The XP disk arrays (including the XP10000) are not “monolithic” or “mainframe”. The XP is more modular and flexible than EMC’s “monolithic” DMX. For instance with the XP you can add disks, processors, cache, disk racks, and host interfaces as you like while it is running with no application downtime—that’s pretty powerful for today’s mission-critical, 24x7 applications. Compare that to EMC’s DMX, to scale from their lowest to their highest configuration requires swapping through several different models. Each EMC DMX only covers half the solution space the XP12000 covers with just one model. To differentiate the XP disk arrays from monolithic, ‘fork-lift’ upgrade solutions like EMC’s DMX, we describe the XP disk arrays as “frame-based”. The XP10000 is NOT a monolithic array. |
|
| Q5. |
Why and when would I sell the XP10000 external storage capability? |
| A5. |
External storage is designed to give the lowest cost per megabyte for applications that require enterprise level features, like mirroring. Applications like online backup and recovery and lower performance bulk data storage in email archive and multimedia may be perfect for external storage. External storage can also be used for data migration. |
|
| Q6. |
Who will perform the installation of the XP10000 components? |
| A6. |
HP Global Services perform the physical installation of XP10000 components. The experience and expertise of the HP Global Services professional ensures a supportable hardware configuration and assures that the factory warranty attached to the XP10000 components will be honored in future service calls. |
|
| Q7. |
How much does it cost to have HP Services install XP10000 components? |
| A7. |
Nothing! There is no additional fee. HP Global Service will perform the physical configuration of the XP10000 free of charge. Basic installation and start up services are included in the purchase price. |
|
| Q8. |
Why purchase an XP10000 disk array from HP? Isn’t it the same as an HDS or Sun version of the Hitachi array? |
| A8. |
HP is the only company that has both an OEM agreement, and an engineering agreement with Hitachi Ltd on XP technology, plus a partnership for improving the core technology. SUN is just a reseller with no value-add. For example, HP offers a more robust solution than HDS. HP has unique firmware and HP invented software such as Cluster Extension, Auto Path, and Performance Advisor. HP also has storage solutions such as multi-site disaster tolerant solutions, fast recovery solutions; and a large services and support organization with a wide selection of services to choose from. |
