Most *cheap* SSDs are SATA. But if you want to use them in a cluster
AFAIK, most ZFS based storage appliance are move to SAS with 7200 rpm or
15k rpm
most SSD are SATA and are connecting to on bd SATA with IO chips

Thanks for the sugestions, especially all the HP info and build

Two things crossed my mind on the hardware front. The first is regarding
the SSDs you have pictured, mounted in sleds. Any Proliant that I've
read about connects the hotswap drives via a SAS backplane. So how did

If you're building from scratch, please choose nearline/midline SAS disks
instead of SATA if you're looking for capacity. For detailed reasoning,

For the server, I've had great success with HP ProLiant systems, focusing
on the DL380 G6/G7 models. If you c
