RE : v5r1 I/O features

Hi Debbie,

We upgraded a 730 to an 830 (and V5R1 in the process) but kept the old
disks, including 2 or 3 6512 controllers. (We discovered the document
you're looking at once the upgrade was already planned and the dates locked
in). We do have a problem with performance for a LANSA web application, but
this application related. The highest disk arm utilization we see on the
system is about 4% and there don't seem to be any I/O bottlenecks.

However, I guess utlimately it would depend on how I/O intensive your
application is.

We are getting ready to upgrade from v4r5 to v5r1 (or v5r2)...anyway I was
going through the list of HARDWARE "that may experience performance
limitations".   Of course we have several of these items.  Has anyone
upgraded with any of these features....and how did it go?    2609 Two-Line
Adapter; 6153 v.35 One-Line adapter; 6050 Twinaxial Workstation Controller;
and 6512 Disk Unit Controller for Raid.

Thanks in advance for any and all help and advice.
