The server is 70TB with about 10TB used. It's RAID6 @ the controller. I'm using FreeBSD's ZFS on a mirrored SSD filesystem and a second 250GB SSD for the ZFS's cache. 2x Xeon 2.1 Quad-core, 32GB RAM. It seems very responsive. I haven't tested I/O any further, not something I've ever spent time on, typically all my FreeBSD installations run great on the GENERIC kernel. When I make a backup of the database on this server, internal disk to disk it runs @ 117,365KB/s. Other servers range from 1,200 KB/s to my first trial desktop client ran @ 12,523KB/s. Occasionally I have a client run ~100KB/s, and I haven't determined why. Most of the clients are interconnected via 1000MB copper Ethernet, although some may be only 100MB, I'll have to investigate further. As I'm thinking thru my potential bottlenecks, the Ethernet backbone has the slowest through-put @ 100MB, perhaps that is the issue?
If I have optimized everything I can find, and still need more inbound data bandwidth is it possible to run multiple sd instances, pointing to the same disk array?
