We have a 2040 HA pair which is now at max spindles (all 15K) to still allow for failover.
We have 4 esxi hosts with approx 120 VM's with a good mix of DB's, App servers, web servers and general services.
We have an NFS datastore per aggr, my aim this year is to segregate datastores from other forms of storage
We do have a second single controller 2040 in a DR/backup server room next door with larger sata disks.
We have fc set up - we had an RDM for a (now defunct) sql cluster. It's not being used right now though
The challenge for this year is to provide a plan for next year for storage expansion and performance improvements
I have been thinking about swapping a larger slower shelf from next door with a small faster shelf here - that would give us capacity - yet to find out if we're 'allowed' to do this by NetApp or if it meets our sizing requirements for next year - early days
on the performance side, I have recently seen qlogic have released 'vmware aware' SSD caching FC san adaptors (Fabricache). Now this looks interesting as it caches locally on the host and retains the cache after a vmotion - all the cache rebuilding traffic happens over the fc side.
With these adpators and the shelf swap we could also keep 100% NetApp for our storage (which makes things easier to manage)
Alternatives are to start looking at products from vendors like Tintri or something like that (which answer the performance AND capacity questions - but it's then another management layer...)
Thoughts? Anyone looked into the qlogic cards?
Any gotchas for swapping NFS for FC?
