[plug][semi-OT] PCIe x1 SCSI RAID cards...are there any?

[sothisistheinternet]

Hi all,

I need to source a PCIe x1 SCSI RAID card (preferably brand name).
Adaptec has a PCIe SCSI card, but it's not a RAID card. We have one
PCIX slot occupied by a SCSI card and we have three PCIe x1 slots to
use, but finding a card for these has been surprisingly difficult.
Linux support would be great, but at this point we'll do what we need
to do with the servers after we determine if we can even get the
required hardware to suit what we already have.

TIA,

Ari
