[zfs-discuss] Question about WD drives with Super Micro systems

2011-08-06 Thread Roy Sigurd Karlsbakk
Hi all We have a few servers with WD Black (and some green) drives on Super Micro systems. We've seen both drives work well with direct attach, but with LSI controllers and Super Micro's SAS expanders, well, that's another story. With those SAS expanders, we've seen numerous drives being

I'm using 4 x WD RE3 1TB drives with a Supermicro X7SB3 mobo with a builtin LSI 1068E controller and a CSE-SAS-833TQ SAS backplane. Have run ZFS with both Solaris and FreeBSD without a problem for a couple years now. Had one drive go bad, but it was caught early by running periodic scrubs.
