2gb FC limits you to 200MB/sec.
My host is connected to DMX4 using 4 HBAs, 2 HBA are in Fabric A and 2 in Fabric B on 4 gb speed FC. Switch to DMX is just 2gbps. I am transfering 1 TB of data from Disk 1 to Disk 2 (Both Disks are from same Storage) I m getting only 90gb/hour. Is it good throughput for this environment?  I am looking for some guide where I can understand the maximum load (IOPS/sec and MB/Sec) that FA can accept it.   This will answer more questions of my performace related issues.  I asking with EMC Live chat but end with no good answer.  Pls reply asap.
Max through put in DMX 4 FA
