using iscsi for the esx datastore

Due to close scare in my lab I decided to switch the datastore from a single onboard hdd to iSCSI. I use a WD MyCloud EX2 Ultra but there are a lot of more advanced NAS out there with a whole host of extra features.

Since moving onto this I haven’t noticed any real performance degradation in my lab, its run over 1 Gig port.
