I have three with 3Gb SAS, of around 40Tb.
Two are on oi148, and the last will be updated soon.
All are Supermicro X7DWN+ in 3U + 4U jbod, with 6 x 1G and 2 x 10G 
network ports.
Shares are SMB and NFS (3 and 4).

These now run the Seagate 2Tb SAS interfaced disks.
The disk choice is critical with expanders.

The next one, due in about a week, will be sas2 with multipath and the 
same disks.


I've had a good run, averaging two "events" a year per server which 
required a reboot or in one case, a full OS reinstall.

My build recipe is a text install and bash script to add/remove packages 
and configure networking etc.

I use snmp for monitoring, including fault managemnt extension.


Mark.

Lately, however, we've seen some hichups that may be related to the platform, rather than the hardware. The actual errors have been variable. Some issues were due to some supermicro backplanes that tended to fail, causing drives to report massive i/o errors. But then, the really bad ones are issues where zfs reports bad drives even though iostat report them as good. So far, we haven't lost a pool, it has been sorted out, but I still wonder what happens if I'm gone for a few weeks and something like that happens.
