Fiber channel ISL utilization
Need help how to calculate the link utilization ?
A pair of ISLs is configured between two Fibre Channel switches with trunking enabled. The trunk is carrying the I/O traffic from several hosts generating a total of 3,000 IOPS with a block size of 32 KB.
Assuming 2 Gb links, what is the ISL utilization?

Based on what you supplied
3000 iops @ 32K = 96000K = 93 MBps = @23% utilization across the 4Gb Trunk.
Remember that you could use Web Tools or ECM Performance Monitoring to get real-time information on this link also.
