Dell UCSB-900, UCSE-900, UCSA-901 Types of virtual disk initialization, Configured spin down delay

Page 27

There are four power-saving modes:

No Power

Savings

(default mode)

Balanced Power Savings

Maximum Power Savings

Customized Power Savings

All power savings features are disabled.

Spin down is enabled only for unconfigured and hot spare disks.

Spin down is enabled for configured, unconfigured, and hot spare disks.

NOTE: The maximum power savings mode is not supported by the H330 PERC card.

All power savings features are customizable. You can specify a Quality of Service window during which the configured disks are excluded from spin-down.

NOTE: The customized power savings mode is not supported by the H330 PERC card.

Configured spin down delay

NOTE: The Configured Spin Down Delay option is not applicable for the No Power Savings mode.

The amount of time to wait before spinning down disks can be set using Configured Spin Down Delay. The minimum value of the timer is 30 minutes (default) and the maximum is one day. Disks are spun down automatically and spun up when accessed. All disks are spun up on reboot.

NOTE: There is a delay in I/O operations when a configured disk is being spun up.

Types of virtual disk initialization

PERC 9 series supports two types of virtual disk initialization:

•Full Initialization

•Fast Initialization

CAUTION: Initializing virtual disks erases files and file systems while keeping the virtual disk configuration intact.

NOTE: The following initialization operations are not applicable for non-RAID disks.

Full initialization

Performing a full initialization on a virtual disk overwrites all blocks and destroys any data that previously existed on the virtual disk. Full initialization of a virtual disk eliminates the need for the virtual disk to undergo a Background initialization (BGI). Full initialization can be performed after the virtual disk is created.

During full initialization, the host cannot access the virtual disk. You can start a full initialization on a virtual disk by using the Slow Initialize option in the Dell OpenManage storage management application. For more information on using the BIOS Configuration Utility to perform a full initialization, see Initializing virtual disks.
