But having a "fake" bios doing raid1 isnt' more stable/better than to emulate raid1 in software?
however, thinking of benchmarks, the machine in question is a dual xeon with 512mb ram doing web,smtp,pop3 and a small mysql for 50 users. I think raid 1 with the linux driver will be more than excellent.
However the main question remains, Why the adaptec 79xx driver does not "see" that I created a raid1 in the bios? why keeps showing me two "drives" instead of one?
Cause that will mean that the linux 79xx is not "fully" compatible (ok, it is 99.999999% compatible) with the AIC-7901 Adaptec 320 with HostRAID (fake BIOS or not).

An INTEL Server motherboard model SE7501BR2 with an onboard Adaptec AIC7901 controller (with HostRAID) is not being recognized by CENTOS 4. The AIC79xx driver loads correctly, however it does not "see" the fact that I used the HostRAID onboard software to create a RAID 1 set.
I went to the INTEL site and only found a driver for RHEL 3.0 and I was unable to find a driver on the adaptec site.
The CENTOS4 installer gives me the option to create partitions, raids, etc. This is not what we want since creating a RAID by software it's supposed to be more slow that doing it hardware based right?
Does the CENTOS4 support the AIC7901 with HostRAID or not?
In Adaptec speak HostRAID is software RAID. What you have is not hardware RAID controller. The card is really just a standard SCSI controller with fake RAID BIOS. Create software RAID devices under CentOS (and you'll get exactly the same thing as if configuring them in BIOS and using Adaptec device driver). _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
