Hi, Adding SAS Disk is ok but expensive :(. Another way is using PAM Card, it's cheaper.
Terimakasih, EKO HARYONO

Hi,
We have a small metrocluster with 2TB SATA disks in DS14mk2 trays, mostly used for VMware. We desperately need more IOPs, and are tossing up another 14x2TB SATA tray, which would have the benefit of just expanding the aggregate, vs 12 of 600GB 15krpm SAS (half a DS4243), which would give more IOPs but be more admin overhead since we'd have to move VMs amongst the shelves.
Capacity isn't a problem, and when we built the metrocluster the ATTO 6500N fibre bridge wasn't available, so SATA was our only option at the time. We're getting quotes for both options, but does anyone have an opinion on expanding the SATA aggregate vs setting up a new SAS one?
Thanks,
