I wonder how much that would change with a bbu NVRAM card for an external journal for ext4 and the disks on md. Unless one cannot add a bbu NVRAM card...
Good question, they are after all ( the Sun 45xx's ) just opteron box's with a mostly standard build. Finding a CentOS compatible ( drivers pre-included, and not crap like cciss ) would not be too hard.
With ZFS, the whole machine is the RAID-controller (basically). NVRAM in ZFS would be used for L2ARC. Of course, this ask for a sane system-desgin (which the thumpers do have, as mentioned - AFAIK, there are virtually no off-the-shelf motherboads that can offer the thumper's distribution of SATA-channels over HT-links.
CentOS wouldn't run bad on such a motherboard, either (and RHEL is supported). ;-)
Last time I checked only RHEL4 was support.. RHEL5 lacks (properly working) SATA driver for the controller used in the thumper.
Is RHEL5 supported/working nowadays?
