Advantages and Disadvantages of Virtual Data Mover
A customer engineer asked me a question regarding the Advantages and Disadvantages of a Virtual Data Mover (VDM). Because he didn't see the need to use VDM.
Because I just joint EMC 2months ago without any prior knowledge on data storage, I only manage to provide some functions from the training booklets and other external storage forums. Such as:
1) Allow administrator to group CIFS servers and file systems into virtual container.
2) Serve as a purpose to share the loads of the physical DMs.
3) Able to perform replication with remote DMs for data recovery purpose.
4) Can be easily move from one physical DMs to another.
Are these answers good enough to reply customer's question on the VDM advantages part? Did I missed out anything? But I do not know how to answer the Disadvantages section. Can any NAS/Celerra experts help me with this?
