Concurrent maintenance on the HP EVA
Concurrent maintenance is the capability to complete I/O operations to an HP EVA while simultaneously completing maintenance operations on it.
Quorum disks on HP StorageWorks EVA systems The Lenovo Storage V7000clustered system selects managed disks (MDisks) that are presented by HP StorageWorks EVA systems as quorum disks.
Copy functions for HP StorageWorks EVA systems Advanced copy functions for HP StorageWorks EVA systems (for example, VSnap and SnapClone) cannot be used with disks that are managed by the Lenovo Storage V7000clustered system because the copy function does not extend to the Lenovo Storage V7000 cache.
Logical unit configuration on the HP EVA
An EVA logical unit is referred to as a volume. An EVA system can support up to 512 volumes. Volumes are created within a set of physical disk drives, referred to as a disk group. A volume is striped across all the drives in the group.
Logical unit presentation
A volume must be explicitly presented to a host before it can be used for I/O operations.
Configuration interface for the HP EVA
The HP EVA is configured, managed, and monitored through a Storage Management Appliance. The Storage Management Appliance is a server that runs a software agent called Command View EVA. The Command View EVA is accessed using a graphical user interface that is provided by a standard web browser.
