Thanks guys for yours the reply!
I looked a formulas or something that will give me the specific answer, because if I have a one HBA in a server with 4 FC ports (4gbps), VCOPS will just tell me that if max bandwidth will be 16gb my remaining time will be zero, but I'm looking for how VCOPS knows how much IOPS are left (remaining time), something like this:
VCOPS "see/learn" that in X IOPS the disk latencies becoming high and can't provide a normal operation (by VMware above 10ms is not a best practice)
Thanks Again,
Roni
