I'm using it with a Kingston SSDNow V+200 (SF-2281) 60GB:
# hdparm -tT /dev/sdb1
Timing cached reads: 22586 MB in 2.00 seconds = 11302.81 MB/sec
Timing buffered disk reads: 500 MB in 3.00 seconds = 166.43 MB/sec
If it will fit your needs, I don't know. It's cheap and fulfill...
There are both internal and external versions, I have the card with two internal ports.
Some cards have two internal and two external but only two ports will work at the same time I think. Check ASmedia 1061 on eBay and I'm sure you'll find cards with internal ports.
For example this one...
What kind of speeds are you seeing on your NFS? I'm currently using a separate NAS but speeds are not as good as I was hoping for so I'm debating whether I should move to a virtualized NAS/SAN. Are you using NFS in sync or async mode?
If you're looking for cheap then I can recommend a ASMedia 1061-based card.
I've got one and it works fine with ESXi 5.1, even in pass-through mode if your setup supports that.
Can be bought for $13: http://www.ebay.com/itm/271014212322?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
I won't need the warranty as it's only for my personal use I want it to be quiet and have low power comsumption.
The server will run diskless or with one SSD, the VMDKs will be on a NAS. What do you mean with quad card?
My favorite retailer has the FUJITSU PRIMERGY TX100 S3P E3-1220V2 with 2x4GB ECC RAM and 2X500GB HDDs for ~$600USD.
For the same price however I can build a white box with the following specs:
Intel Xeon E3-1230v2 (with Hyper-Threading!)
32GB RAM (non-ECC)
