VMWare : Datastore on iScsi SAN or on local HD - need advices
Posted on 2010-08-24
I need an advice about Datastore storage. Situation : ESX Servers (DELL PE 2950), SAN iScsi (DELL MD3000i), company between 70-80 people.
What are the pros and cons of placing the datastore of a particular VM (for example a SQLServer 2005, or a File Server, or a TS Server) on the ESX server HD, and not on the MD3000i ?
Could the performance increase / decrease, assuming that the internal disks are "good". I'm for example thinking of migrating a File Server as a VM (1 To of data, about 1M files), and want to choose the best solution for the placement of the datastore.
Thanks in advance.
