[CentOS] SAS raid controllers

Is anyone running either the newish Adaptec 5805 or the new LSI (3ware) 9750
sas raid controllers in a production environment with Centos 5.3/5.4?

The low price of these cards makes me suspicious, compared to the more
expensive pre-merger 3ware cards and considerably more expensive Areca
ARC-1680.  I've been 'burned' by the low cost of Promise raid cards (just as
this group pointed out, they're crap cards!), but I'm still not convinced
that most expensive == best.

When it comes to parallel scsi cards, Adaptec has always been my choice
regardless of platform, but I've never used their serial scsi products.  I
have several older pre-merger 3ware cards installed and have been working
flawlessly for years, but under a windows environment.

I noticed none of these manufacturers are listed on the upstream provider's
HCL, yet they all eagerly claim "Linux" support on their respective
websites..  The Adapetc website actually names both Centos and the upstream
provider as 'supported'.

Kind Regards,
