We are going to tech refresh servers and upgrade vSphere & VC 5 std to 6.5 std, hope to get some recommendation or best practice for our current setup,
Site A (Primary DC)
2 x vSphere 5 std
local datastore
20+ VMs
1 VM VC 5 std
Site B (Secondary DC)
1 x vSphere 5 std
local datastore
10+ VMs
Both sites VMs are active, some have standby services for other site, there isn't any SAN/NAS just local storage in servers, no vm/storage vmotion as network mix of 100mbps & 1000mbps, entire company infrastructures are running in above 3 vSphere.
So what are the options we have to upgrade those HW & SW and also like to minimize or no IP address changes at all, lastly we only have about USD100K budget.
thanks in advance!
