We have a site with an Equallogic (50TBs) that we plan to migrate to a NetApp FAS3220.
iSCSI LUNs (RDMs)
ESXi 5 IBM Hosts
NFS Datastores (No RDMS)
ESXi 5.5 Cisco Hosts
This is a virtual migration to get off of the older Equallogic/IBM system. We have a few large file servers with large format files (2-4TB) volumes. Outages can be taken nightly and on the weekends. Some of these servers will be replaced with newer VMs and we will use a process like ROBOCOPY or securecopy to migrate the data over to the newly staged replacement guests. My concern here is for the others. Can VMware Converter handle the conversion of the existings RDMs to VMDKs? If not, any thoughts on how I can accomplish this? Any thoughts on other ways of getting this accomplished??
Thanks for the input Jonathon. Regarding CIFS we use DFS here and last I heard NetApp doesn't play well (or at all) with DFS so the need for a file server remains.
NetApp CIFS works fine if you're just using DFS to create dynamic share paths off a common root. However you can't use NetApp CIFS with DFS-R, a function for having file shares active-active across different geographic locations.
Personally, unless you *need* DFS-R, CIFS off a filer is a better option providing much better flexibility.
