Has anyone had experience with 5820's connected to HSC70's ( with
RA92's )?

I have been less than impressed so far with the IO performance and would
like to find out if anyone else has had similar experiences with the 5820.

What range of IO performance do you get ?

Also, we have the CI configured as another network and have been transmitting
data to the other 5820's via this mechanism.  It appears to be 2x slower than
going over the ethernet connection.

I would like to find out if we are doing something wrong or if this
is normal performance with the 5820.  Interresting that the DS5000 IO
performance even with scsi drives appears to be faster than the 5820.

Again, since we just installed these machines ( about a month ago ), it could
be related to setup.
