We are achieveing consistently acheivieng 35990 E11 transfer rates of 60GB,
now I will consede the more small object the slower things get but our
nightly backups of full production ( NO systems ) runs on the average of
60 GB.

What is different is the 3590s E11 are on the PCI towers via attach ( 2729
?)
. We did see that around 50% improvement in the 3590 upgrade from B11 to
E11 on our model 730 8 way

Why is it you say one must go to an 8xx series and use the PCI to drive
the E11s at rated speeds? uou must have some caveat in mind

Yes.� Your model 730 is not fast enough to drive the E11 at rated speed!

You will need to upgrade to an 8xx box and attach the E11 through PCI.

Sorry

I currently have a model 730 running V4R4 and have currently upgraded from a
3590 B11 to a 3590 E11. The drive is attached to a 6534 SCSI SPD card.� I'm
not seeing the promised 50% increase on my full system backups. The backups
have run for 10 hours on both the B11 and E11.� IBM states that the E11 has
a faster data transfer rate of 14mbs vs 9mbs for the B11.� Has anyone
experienced this problem? Any suggestions?� Thanks
