That is a fair assumption.

There is no need to download drivers from LSI Logic's web site.

According to their support website it uses the same MegaRAID driver as
their SATA and SCSI RAID soltuions.

With RHEL2.1/CentOS 2.1 it'll use megaraid.

With RHEL3/CentOS 3 it'll use either megaraid or megaraid2 (the former
will be the default)

RHEL4/CentOS 4 should work but you may have an issue with PCI IDs - the
new driver (megaraid_mbox) will work with the older cards such as this,
but lacks the PCI IDs to properly recognize them.

Dell used to use them as their CERC cards before they switched to SATA.
