I built a small RAIDZ box for media storage and backups. I put 3 WD 2TB Reds in an HP N40L Microserver and paired it with 16GB of ram (overkill?) I'm not looking to break any performance records here, just want to make sure what I'm seeing is typical for such a setup, and figured if anybody is in the market for something similar, maybe they could get an idea of what the performance is like. Just for kicks I'll probably install Virtualbox and throw a Windows VM in there, connect an iSCSI disk and benchmark it. But that will come later.

Here's my benchmark results:
ZFSguru 0.2.0-beta8 (9.1-004) pool benchmark
Pool : Tank (5.44T, 3% full)
Test size : 64 GiB
normal read : 295 MB/s
normal write : 180 MB/s
I/O bandwidth : 2 GB/s



Transferring a file from the server to one of my machines results in about 110MB/s sustained, which is pretty close to saturating the gigabit link.

I love these microservers for ZFSguru, as I have both the N36L and N40L systems in use currently. Below are the results from one of my N36L systems with 8GB ram and 4 3TB WD Green drives.

ZFSguru 0.2.0-beta8 (9.1-004) pool benchmark
Pool : pool1raidz (10.9T, 19% full)
Test size : 64 GiB
normal read : 206 MB/s
normal write : 187 MB/s
I/O bandwidth : 2 GB/s

Thanks for posting the benchmark. I wonder if my faster read speeds are due to the faster processor of the N40L versus the N36L? At any rate it's good to see my numbers pretty much on par with yours. For what it's worth, if you're looking to use 16GB of ram in these Microservers, 2 Kingston KVR1333D3E9S/8G modules will work, despite the 8GB limitation.

Mine are Green drives so I would expect them to be slow, but I do have an extra drive/spindle to boost the pool speed. I will keep the 16gb in mind as an upgrade or possibly for the next system I build, and good to hear it works.
