Host ports are all at 4Gb/s Fibre Channel.

Please define what you mean with read/write. There are a lot of "it depends".

Speed can be fast. Good enough?

• Do you want to know how fast it is when it's maxed out?
• Or when there's three disk shelfs.
• SSD/SAS/FATA drives.
• What kind of copy - windows file copy. dd. iozone. Ior or what kind of benchmark??
• Which cache size?
• Do you want iops, transfer rate, line rate
• What is the size of a normal IO? 
• Speed from file server (with block storage from EVA) or from client behind a file server

The FC host ports are all at 4Gb = 400MB/s. See http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c01677617&lang=en&cc=us&taskId=&prodSeriesId=3900918&prodTypeId=12169 for details.

So if you only look at fc connectivity then the max speed is 4Gb*$(amount of host/device ports) = 4*8=32Gbps = 3200MB/s.

Theoretical max.
