The Array Configuration Utility is provided for more advanced configuration support. The Array
. .
Configuration Utility is an easy-to-use graphical configuration utility to help users set up and
. .
. .
change the drive array configurations. It can be used to configure the standard internal drive
. .
controller as well as any optional controller boards that are installed.
. .
. .
. .
RAID Support
. .
. .
The integrated array controller supports RAID levels 0, 1, 0+1, and 5 to ensure data integrity and
. .
. .
availability. When configured for RAID 5, the controller proactively generates parity data so that
. .
it can keep all data available and the server running during replacement of a failed drive. The
. .
. .
integrated array controller also supports online spare disk drives. These spares are powered up but
. .
not active; they are held in reserve in case one or more of the active drives should fail.
. .
. .
. . The controller supports logical drive expansion, which consists of three different types of
. .
operations: capacity expansion, RAID migration, and distribution factor changing. Capacity
. .
. . expansion can occur by either adding additional physical drives or using existing free space on the
. .
current physical drives. RAID migration refers to changing the RAID level of an existing logical
. .
drive. Distribution factor is the amount of data stored on each physical drive for a RAID stripe.
. .
. .
All of these change operations can be performed without disturbing the data on the drives.
. .
. .
The integrated array controller in the ProLiant DL590/64 server can be bypassed using the
. .
. .
Integrated Array Bypass Kit and an optional controller such as the Smart Array 5300 controller.
. .
The bypass kit is shipped standard with all ProLiant DL590/64 servers.

Design excellence in serviceability and manageability enables rapid setup and deployment and
. .
. . easy management of multiple servers in growing data centers.
. .
. .
. . Modularity and Serviceability
. .
. .
The ProLiant DL590/64 server builds upon the trend towards modularity and tool-free
. .
. . serviceability. The modular design reduces the demand on technical staff time, making the
. .
information technology organization more productive.
. .
. .
The easy-to-remove processor/memory drawer (Figure 14) enables easy access to the memory
. .
. .
board. A technician can insert DIMMs without removing the board and minimize downtime by
. .
simply removing the memory board, replacing it with a spare, and debugging the board offline.
