[CentOS] SCSI RAID monitoring

I'm looking to buy some new high-reliability servers (mail server, cluster head node). I'll be doing a hardware RAID1 mirror w/ a hot spare, and I'm trying to decide between SCSI and SATA (albeit SATA w/ WD Raptor drives, so the price difference isn't as big as it would seem at first).

I'm very familiar with 3ware's monitoring tools for their SATA RAID cards, and they work very well. What monitoring tools are out there for SCSI RAID cards? For that matter, what are the preferred SCSI RAID cards supported by centos 3 and/or 4? LSI MegaRAID is the one I'm leaning towards, but I'm open to suggestions.

Thanks.
