I'm looking into buying a refurbished server for practising VMware virtualization (basically building a home datacenter with 1 vCenter, 2 or more clusters with 3-4 ESXi per cluster, and at least about 10-20 VMs (things like 2 Windows Server, 1 SQL Server, 1 Exchange Server, 5-10 Windows 10 end-clients) and to practise vMotion, DRS, FT, and then add on top of that NSX for network virtualization). I have the following specs in mind.
1 x Intel Xeon E5-2600-v3 2.20 8/10/12/16 Core
4 x 1.2TB SAS 10K/15K 2.5"
Integrated NIC 1Gb 2 or 4 Ports
96GB or 112GB
Anyone one having any suggestions from any aspect of having a home server, and their experiences that might help.
