I found a good deal on an IBM x345 server off ebay. It contains 2x 2.6 Xeon CPU's, 4GB RAM, and ServeRAID 5i with 3x SCSI 74GB 10k drives in RAID-5 array. All of this is on a gig network with no jumbo frames.

Last night I installed ESX 3.5. I downloaded the VI client from the ESX server and was pulling about 3.5MBps through http. I installed Windows 2003 on ESX. It took quite a long time, and I think the disk is the culprit.

I use ESX/VMware all day long at work, and even when running on local arrays the speed is what you would expect from raid 5 array and gig network. Yet in my home case, my speeds are drastically slow. Obviously I didn't give much information as to what the problem could be, but can anyone add an input on to what they would expect for typical/optimal speeds in this environment? Or are there any good tools to diagnose or benchmark my disk speeds?

Thanks

Here is a HD Tune result. I'm not quite sure what conclusions can be drawn from this.

A lot depends on if it is a single channel or dual channel or quad channel raid card?

320 640 1280 mbps max.

Single, 320 MBps
