I need advice on some design concerns moving forward. I'll try to lay out what I am working with and where I think we need to be.
~10 to be retired servers
4 VM servers at almost full capacity (12 VMs)
SQL VM with local databases/data warehouse (VM)
Single Exchange 2010 (VM)
1 Bare metal (to be retired PDC) and 2 VM DC's
Single barely breathing file server (critical functionality)
4TB NetGear NAS near capacity (being used as user docs and file server)
ArcServe Backup r16.5 to Dell TL2000 tape drives (only backup solution)
I am wondering what a solid direction would be to add some failover, better file serving, cloud backup, etc.
I have needed to reset this NAS drive due to all the heavy use it gets and issues with permissions. This is frequent enough that the decision makers are willing to spend some money to make some changes.
Bear in mind we are very Dell heavy and I don't expect that to change. My boss has me looking at PowerVault storage now but I am unsure as to the best practice/direction to take given the current topology.
I have been thinking another Exchange server (cloud maybe?) Another SQL server as load balance or backup (cloud also?), Powervault for shared storage and VM/database use?
Thanks everyone I value your input and experience.
