Subject: Supported Raid Controller



Can anyone tell me or tell me where I can find out if the following Raid
Controller are directly supported by Red Hat AS version 4? That is I do
not have to go to the vendor to get a driver.

Serveraid 8I SAS 
Serveraid 6M 

Other questions depending on the answer to the first question. 
1) Can I do an initial load with these controllers? That is I do not
have to have some other drive to load on first and then put other file
systems on the drives controlled by these controllers.

2) Any pros or cons about these controllers? Easy to configure,
performance as advertised, etc. 

Thanks in advance.

[Jack Allen] Well no one said anything or ask for more information. 

    After I unpacked the boxes, I found out both controller are made by
Adaptec. The system is an IBM xServer 366. The ServeRaid 8I plugs into a
special slot. The SAS disk drives are already cabled to a special I/O
card. The controller then controls the drives through that card. At boot
time you can access the setup for the 8i card. The system had 2 34G
drive and I set them up in Raid 1, mirrored pair. The ServeRaid 6M
allows you to look at the setup, but not create any disk arrays at boot
time. The system came with an Initial Setup CD. It clears all the disk,
sets the date and time, updates and sets up ServeRaid controllers and a
few other things. And guess how this is done. It runs Linux very much
like the Red Hat install does and leads you through each step. It even
updated the microcode on the 6M controller and ran the array setup. The
disk shelf had 12 36G drives with a split SCSI buss. So 6 of the disk
are accessed by channel 1 of the controller and the other 6 disk are
accessed by channel 2 of the controller. So I created 6 Raid 1, mirrored
pairs, 1 disk from each channel for each pair. When all this was done I
booted the Red Hat AS 4 CD and installed it.

    So the answer to my questions are, yes Red Hat AS 4 supports the
controller and yes they are fairly easy to configure. Performance seems
to be real good based on the limit amount of things I have done that use
the disk.

    Now I have other questions about Red Hat AS 4 that will follow
shortly.
