Improved Write Performance
The Image Server 2000™ uses new designs to improve RAID 5 write performance for both large
sequential and small random transactions. This advanced block caching firmware delivers
extremely high performance for RAID 5 write operations.
Managing Disk Arrays
The Image Server’s Disk Array Configuration Utility provides tools for monitoring and
managing the disk array. Monitoring and troubleshooting programs automatically check the
array and report problems. The Image Server console provides access to RAID status
information and service options.
Error Notification and Repair
The Image Server 2000 will notify users in the event of a fault by flashing the front panel
DRIVES
light. A flashing
DRIVES

response to a flashing light is to open the RAID Status window from the On-Screen Start Menu.
Click
Start > System > RAID Status
to launch the Array Configuration Utility.
The RAID Status Home window (Figure 20) displays the current status of the RAID controller
and all disks connected to the RAID system.
