TC020702TB TECHNOLOGY BRIEF (cont.) ... 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. RAPID DEPLOYMENT AND MAINTENANCE 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.

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.
