Management software support
HP StoreVirtual 4000 Storage supports target-based management interfaces, including the HP
StoreVirtual Centralized Management Console for Windows and Linux(CMC), Command Line
Interface for Windows (CLIQ), and on-node command line interface (SSH to storage node using
port 16022).
For more information, see the following documents, available at www.hp.com/go/P4000Support
(see Manuals section):
• HP StoreVirtual Command-Line Interface User Manual
• HP StoreVirtual 4000 Storage User Guide
Maximum configurations
HP StoreVirtual Centralized Management Console shows a Configuration Summary which reports
information about storage items, including color-coded status regarding recommended limits based
on performance and scalability.
• When a configuration category is nearing the maximum recommended limit, the navigation
window displays the category information as orange.
• When a configuration category reaches the maximum recommended limit, the navigation
window displays the category information as red.
• When the number in that category is reduced, the color changes immediately to reflect the
new state.
For example, if you have numerous schedules for a large number of volumes that are creating and
deleting snapshots. When the number of snapshots approaches the maximum recommended
number, the summary bar changes from green to orange. After enough snapshots are deleted from
the schedule, the summary bar returns to green.
Best practices
The optimal and recommended number of storage items in a management group depends on the
network environment, configuration of the management groups and clusters, applications accessing
the volumes, and purpose of using snapshots. The following sections contain guidelines that can
help you manage HP StoreVirtual to obtain the best and safest performance and scalability for
your circumstances. These guidelines are in line with tested limits for common configurations and
uses. Exceeding these guidelines does not necessarily cause any problems. However, storage
performance can be less than optimal or in some failover and recovery situations, can cause issues
with volume availability.
Table 177 (page 332) describes the recommended maximum configurations.
