RocketRAID BIOS Utility

1. Array Type: First, use the Tab or arrow keys to highlight the desired RAID level,

and press the Spacebar to select the Array Type. The RocketRAID 432x host

adapters support RAID 0, 1, 3, 5, 6, 10, 50 and JBOD.

2. Cache Policy: Specify the Cache Policy of the array.

a. None: No cache policy set

b. Write-back – utilizes disk cache. Default setting, optimal for

performance.

c. Write-through – data is written directly to disk. More secure than

Write-back, but will perform slower.

3. Init Method – For redundant arrays (RAID 1, 3, 5, 6, 10 and 50) specify the RAID

Initialization method.

a. Quick init – use this option if you want to quickly create an array

for testing purposes. This will clear all previous data, and will not

build parity. Do not use this method if data integrity is priority.

b. Foreground – this will instruct the host adapter BIOS utility to start

the initialization process immediately after creating the array. This

option is recommended for data security.

c. Background – this will instruct the host adapter to initialize the

array in the background, after the operating system has booted.

Consider this option if you need to install an operating system to

the array – this allows the array to be used immediately.
