plus four 1.6TB solid state disks
Are you sure this wasn't 4x400Gb SSD drives?
If not, these 1.6TB SSD's retail for £3000-£5000 each.. so $32000 (or about £19000) is actually not a bad price for that server.
VMware has officially shunted its VSAN virtual storage area network out the door at $2,495 per CPU. The company has also released VMware Virtual SAN for Desktop at $50 per desktop. You can buy one without the other, if you please. Virtzilla's Compatibility Guide also offers some insights into the cost of a server tricked out …
You can use existing hardware!
There are two ways of deploying VSAN
1. Bulild your own VSAN using existing og new hardware
VSAN supports ANY server on the vSphere 5.5 HCL list.
The only components requiring special VSAN certification is disk controllers, harddives, SSD's and PCIe flash devices.
2. Buy a VSAN Ready Node
Do you think those CPUs in storage arrays are there just to help keep the HBAs cozy and warm? It takes compute power to run a real array and host IO directed at it and probably more so for a virtual array. There's no free lunch! You'll have to take your existing compute needs and then add the storage load onto that. You aren't going to be able to squeeze VSAN into an already fully loaded compute farm. You can try, but you'd better have your resume freshened up first or a forgiving manager with the Dell rep's number on speed dial.
