This point > in their description seems to confirm that: It's interesting that the vendor (ICC) advertises this as a 12-disk box, yet it's only an 8-disk chassis. Additionally, the PSUs are 720W, not 800W, so I'm not sure why they claim that either. The chassis in question is almost certainly a Supermicro SC825TQ-R720UB, by the way: http://www.supermicro.com/products/chassis/2U/825/SC825TQ-R720U.cfm The picture doesn't show the front bezel serial/USB ports mounted, but they're visible on the SuperServer 6026T-URF (which is probably what ICC is selling anyway, pre-populated with CPUs, RAM, etc.): http://www.supermicro.com/products/system/2U/6026/SYS-6026T-URF.cfm > That's a Linux based commercial NAS system that you install or > plug into standard servers to turn them into a NAS. > > See http://www.open-e.com/ > > So, IMHO, yes, you should be able to replace that DSS stuff with > either stock FreeBSD or preferrably FreeNAS to turn one of these > boxes into a ZFS based NAS.

It would be even better to simply ask them what exact Supermicro hardware (specifically, model numbers) they're using to build these systems. You can see Supermicro mentioned in the of their site, so that's definitely what they're using, even down to the controller card offerings (some of which (Marvell) are known to behave oddly on FreeBSD (yes there are success stories, but there are also follow-up horror stories) -- consider yourself warned). -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
