Clariion Migration CX700 to CX4-240 SAN Copy- Full Session Speed
I am sure it has been asked alot, but what throughput speed can one expect on a Full Session copy from a CX700 to a CX4-240 2GB/sec SAN?
We would just pull from the CX700 to the CX4-240 (SAN with Licensed version of SAN Copy) We will zone at least 1 FC connection between each SP on each clariion and use the Max Throttle value of 10.
What was your experience?

. I migrated from CX600 to CX-480 ..was getting around 80 MB/s at throttle 7.

i was pushing with source array under full workload, 800MB/s ?? ...that's a lot of spindles doing the work. I saw significant decrease in performance as i started more concurrent SanCopy sessions that were hitting the same spindles, it eventually became random workload on CX600 and copy speeds went south. Your milage may vary

80MBps That is slow for FC. I would expect 10 times that much for a SAN copy over FC from array to array? Were you pushing or pulling, I am thinking of doing a FULL pull with NO i/o from the hosts.

800MBps is if I am utilizing 4 FC ports on the CX700. Just moving the data from one SAN to another, and of course LOTS of spindles.

good paper in case you don't have it already, no definite numbers though

Yes, I read that one as well, I guess because there is so many factors there is really no good numbers, I was hoping someone else has done a full copy sessions (PULL) and could share their experiences.
