integrated SATA RAID controller on Intel server board SE7520bd2

[Gayn Winters]

Olga,

I'm afraid you are ALMOST out of luck.  The 7520 chipset contains the
ICH5R controller.  To support RAID1, the ata driver needs the mk3
patches, which are not in 5.4-RELEASE.  You can, as you suggest,
implement RAID1 in software.  There are several postings on this topic.
You could also add a RAID controller card.  There are many postings on
this as well, but if you want an all-Intel configuration, Intel's
website lists two compatible Intel RAID boards.
