AS/400 Performance

[jtiss]

Ok, here is a JDE performance question...

We have:

an AS/400 (9406) V4R5 with one processor and 2gig of memory.
two netfinities (333mhz at 256mb memory)

40 NT 6a FAT PC's with 100mbs NIC cards.

Between the 400 and the PC's, we have a HP Procurve 4000m switch.

Currently, we have three NIC cards coming out of the 400; one for each
netfinity and one for the 400 itself. All objects are stored on the 400
directly.

We have checked the most of the JDE database file transfer rates and they
are set to 1terabite on the 400.

We have looked into replacing the current 100mbs AS/400 NIC card with a
fiber Gigabit Ethernet module and adding a fiber Gigabit module on the 4000m
switch.

Has anyone worked with an AS/400 gigabit NIC card and seen overall network
performance run times improve?

What else can be done to boost hardware/software performance?

Jeremy,

good job of stating the hardware configuration.

However a couple of things are missing:

1) JDE S/W configuration / version, etc
2) A statement of what the problem is.

Throw that out and all of the AS/400 gurus out here will jump on your issue (or issues)

Cheers,

Hi Jeremy,

Are the utilizations of your cards high? Is the network utilization high,
(or the line utilization on that port)? You can look at the avg utilzation
for the 400's line description on the performance tools system report to
see how heavily utilized the line is. And you can look at the IOP
utilization on the component report for that line's resource to see how
heavily utilized the card itself is. I'm not sure what a good ethernet
utilization is, maybe 40-60%. Any ethernet gurus out there have a good
rule of thumb? For the IOP, I've heard 40% is high, but I haven't
actually tested it too much to see what the results are of driving it past
there. sorry I don't have hard guidelines, but at least it will give you
something to look at!

If the network isn't heavily used now, then I doubt you will see a big
difference with 1Gb cards. If you do have a bandwidth problem, then they
would help. We haven't been using Gb cards too much in our testing yet,
since our utilizations are low and they probably wouldn't have a big
impact. Generally speaking, at least in our lab environments, the network
isn't usually the bottleneck....

If the utilizations are low and you are definitely seeing problems, make
sure all of the ports are communicating at 100Mb full duplex. Depending on
the switch, autosense doesn't always work well and you might have to set
the ports manually. Make sure to check/change all the ports, including 400
line, INS 1card properties, INS card 2 properties, and the switch's port
for each of them.

Good Luck!
