This might be interesting for some
We bought two PS6000’s 10/09
One came with a bum controller card which was replaced Quickly. Then 12/09 we lost a drive on the same PS6000. Then the PS6000’s have note had issues (as of Jan 27 2010)
We also bought a PS4000 at the same time
It lost its first drive on 12/12/09
then its second drive on 12/15/09
then its third drive on 1/26/10
This has been a little too frequent for my tastes….
No data has been lost and the failovers have worked flawlessly. It makes me wonder about that whole SATA versus SAS reliability thing though.
