Apologies if it is uncool to resurrect old threads.  I have a pair of A5000
arrays, both 22 disk.  Actually, one may be an A5200, I am not sure.  This is
for home use and they are loaded with 44x 15K 73GB drives, ST373454FC, and are
connected to a v40z running OpenSolaris.

Someone commented on performance.  The two arrays are running in split-loop
mode, giving 4 arrays each with 11 disks.  Each array has two 1gb loops attached
to it.  That provides 8x 1gb speed.  The arrays are connected through two 2gb
8-port FC switches (one Silkworm 3200 and one Silkworm 3250) and tied to the
host via 4x 2gb HBA ports.  Theoretically I should see close to 800MB/s of
throughput, but the most I have seen during zfs scrubs is just under 400MB/s. 
For home use, that seems sufficient right now.

Back on topic, this thread caught my eye because I am trying slowly to replace
the 73GB drives with slower 10K 300GB, ST3300007FCV drives.

I had one used drive show up yesterday and it immediately faulted, yellow light
blinking and disrupting both loops in the array.  I have another showing up
tomorrow and I am hoping I only have a bad drive, not that these won't work in
the arrays.

Has anyone used this drive in this array?  Am I doomed to failure?

Thanks,
Marty
