Due to customer demand, a couple of days ago, Beijie learned about the advantages and disadvantages of using NAS in VM ESX. Personally, I believe that using ISCSI storage in VM ESX is a relatively economical and practical solution. The existence of software-based ISCSI (such as OPENFILER, WINTARGET, FREENAS) addresses the issues of cost and performance faced by small and medium-sized enterprises.
