I need to replace a slow HP MSA20 that’s a bottleneck right now (We are an HP shop). HP’s only option with 3.5” SATA drives is stuck at SATA I behind a SAS controller.

Dell makes an MD1000 that claims SATA II speeds behind a SAS Perc 5/E (Don’t know anything about dell).

Anyone got any real world info they can share? I need 3.5” SATA II at least 12 drives behind SAS,

I am not concerned about space and could use multiple 1u chassis if I had to.



Promise VTRAK J610sS?

We use it with Solaris and ZFS - I'm not too keen on using LVM on more than a handful of disks. IMO, 16 disks is probably the minimum to get some decent non-linear performance out of SATA.

If you have the money, you can go for a SUN J4500 ;-)
