About Your System
• Up to 2 TB (2036 GB) storage on a single virtual disk
• Support for up to two PowerVault MD1000 expansion enclosures through SAS Out port connectors on
the RAID controller modules
NOTE:
These numbers represent maximum theoretical performance based on system architecture. Actual
performance depends on customer environment and application usage.
• Online firmware updates (without taking the enclosure offline) for the following components:
– RAID controller modules
– NVSRAM
– Expansion enclosure management modules (EMMs)
– Physical disks
NOTICE:
When updating physical disk firmware, you should stop all I/O activity to the array to prevent data loss.
• Task-based configuration software
• Optional snapshot virtual disk (premium feature), up to four snapshots per virtual disk and 128
snapshots per array
• Optional virtual disk copy (premium feature), up to 255 virtual disk copies per array
• Continuous background event monitoring for critical problems, such as impending physical disk
failure or failed RAID controller modules
• Host-based, multipath failover software for redundant configurations to automatically reroute I/O
activity from a failed, offline, or removed RAID controller module to its alternate RAID controller
module (or from a failed HBA to its peer HBA). This capability maintains a data path between the host
and the storage array.
Modular Disk Storage Manager
The Modular Disk (MD) Storage Manager software is a graphic interface with wizard-guided tools and a
task-based management structure designed to reduce the complexity of installation, configuration,
management, and diagnostic tasks. MD Storage Manager can be used on any server attached to the
storage array, as well as on storage management stations connected to the same subnetwork as the RAID
enclosure, to create and manage multiple storage arrays.
For more information, see the MD Storage Manager User's Guide.
