Chapter 1 Overview of HP NetRAID Utilities

NOTE Write-Back means that data is written to disk only when it is

forced out of the cache. Write-Back is efficient because an

entry may be written many times in the cache without a disk

access. While this setting increases performance, data can be

lost if power fails.

Write-Back is NOT recommended unless one of the following

is true:

• The HP NetRAID adapter is an HP NetRAID-3Si, which

has a Battery Backup Unit.

• Your system is equipped with a UPS (uninterruptible

power supply).

• Your system is an HP NetServer LH 3000/3000r,

LH 6000/6000r, or LT 6000r that is equipped with a

charged accessory Battery Backup Module.

Write-Back is not certified for any logical drive used as a

Novell NetWare volume.
