I have a storage server its constantly heavy writing and reading (at
times) though not with high concurrency:

I have another another in another dc, but less capacity:

Both are the following:
HP ProLiant DL385 G2
dual dual core AMD 2.2Ghz cpus
3 x Nexsan SataBEAST for the san.
Inbound about 900Mb/s, uptime has generally been 3-4 months before
increasing the ZFS arc/KVM sizes. I should just max it out but its
relatively stable. Am looking for ZFSv8+ for L2Arc and separate ZIL.
Load averages about ~ 1.0 . My wish list would be KVM support fot 64GB
ARC, fusion-IO driver support for the ZIL, version 8 of ZFS in FreeBSD
7.2, active multipath, etc, etc..
It works, its stable, its production, but its not like i am cvsuping
ports tree 100 times concurrently.
