New Mylex PCI RAID Controllers

Figure 4-23. Controller Options Dialog Box For New PCI DAC

In the Controller Options dialog box (Figure 4-23), you have the option to do

any of the following:

• Enable (by checking) or disable (by unchecking) any of the following

Global Parameters:

• Automatic Rebuild Management. Works in conjunction with SAF-

TE disk array enclosures to detect removal of a failed drive and

perform an automatic rebuild after installation of a replacement

drive.

• Read Ahead. Reads data to the next stripe boundary (based on stripe

size) and retains in cache any data beyond the size of the actual read

request.

• Background Initialization. Allows logical drive initialization to

take place “behind the scenes” so that the logical drive is

immediately available for use. If you disable this option, logical

drives will need to complete their initialization process before they

can be used.

1. These controllers include AcceleRAID 352 and eXtremeRAID

2000 PCI to Ultra 160 SCSI controllers, and the eXtremeRAID

3000 PCI to Fibre Channel controller.
