| Q1. |
Is HP EVA Dynamic Capacity Management Software the same as other thin provisioning solutions? |
| A1. |
HP EVA Dynamic Capacity Management Software and other Thin Provisioning solutions are all designed to automate provisioning of storage and improve capacity utilization. The most significant difference between the solutions is in the technical approach. For that reason, HP EVA Dynamic Capacity Management Software is often referred to as adaptive, or dynamic provisioning by industry professionals. |
 |
| Q2. |
What is unique about HP EVA Dynamic Capacity Management Software? |
| A2. |
EVA DC-Management Software has the ability to coordinate capacity expansion and reclamation with both the host file system and the HP Enterprise Virtual Array (EVA) virtual disk (Vdisk). This ensures that applications are aware of their storage allocation and helps protect data during expand and shrink operations. |
|
| Q3. |
Is the HP EVA Dynamic Capacity Management Software a licensed feature of the HP Enterprise Virtual Array (EVA) Family? |
| A3. |
Yes, the feature is licensed similar to that of other EVA array based software with a choice of 1TB increments, or an unlimited capacity option. |
|
| Q4. |
What operating systems are supported with EVA DC-Management Software? |
| A4. |
EVA DC-Management Software supports several Microsoft Windows, HP-UX and Linux operating systems. Consult the EVA Software Compatibility matrix for a full list of supported operating systems. |
|
| Q5. |
Does EVA DC-Management Software support all of the HP Enterprise Virtual Array (EVA) models? |
| A5. |
Yes, EVA DC-Management Software supports all of the EVA models but will be dependent on some firmware features. For example, an EVA3000 does not support the shrinking of a Vdisk, therefore EVA DC-Management Software will not be able to shrink a Vdisk. Please refer to the compatibility matrix for supported EVA models and firmware versions. |
|
| Q6. |
Does EVA DC-Management Software require the use of a host agent? |
| A6. |
Yes, EVA DC-Management Software uses a host agent to communicate, coordinate and execute operations on the host. |
|
| Q7. |
Does EVA DC-Management Software support expand and shrink of volumes in all cases? |
| A7. |
No, EVA DC-Management Software will coordinate the automatic expand and shrink operation of volumes only if that feature is supported by the operating system and, or storage firmware. For example, Windows 2003 supports expansion of a host volume, but not shrink, whereas Windows 2008 will support both expand and shrink operations. |
|
| Q8. |
Can the start time of extend and shrink operations be controlled so it does not impact peak production times or backup windows? |
| A8. |
Yes, EVA DC-Management Software has a scheduling option that allows the administrator to specify when extend and shrink operations can occur. |
|
| Q9. |
Does EVA DC-Management Software provide alerts when extend or shrink operation have occurred? |
| A9. |
Yes, EVA DC-Management Software can easily be configured to alert an individual via e-mail to the details of a extend or shrink operation. |
