GWTune

[Marcos Vianna]

Dearr Friends,

I have a Netware 6.5 SP5 running on a Dell 2850 2 GB RAM and 130GB RAID5
disks.
This server supports a GW 6.5.7 with GWIA and WebAccess. The PO has 120
users and the space used is 90 GB of an NSS partition, and no documents -
only e-mail (and some few calendar users).
I have around 1.000.000 files in the PO directory and the server seems to
be some how slower lately. Some users have more than 2 GB mailboxes.
My questions are:
1 - What parameters of GWTune would be usefull to me? One TID (10065215)
says that NSS tunning is not necessary in NW 6.5 since it will dynamically
ajust itself.
" ** With 6.5 and all later versions of NetWare, tuning NSS will not be
necessary as the cachebalance will default to 85% and all other tuning
parameters that may affect GroupWise will be dynamically adjusted by NSS.
You do not need to change the numbonds with NetWare 6.5 ** "
2 - I'm planning to upgrade the memory to 4GB. I think that it will help. Am
I right?
3 - Can I consider this configuration and usage is OK to GW? Or am I near
some kind of limit fo NSS or GW?


Thanks for your help,

Sincerely

Marcos Vianna

The single biggest difference will be the increase in sequential
elevator seeking. There are some improvements that you can make to
NSS and those are outlined in gwtune.ncf, but to be honest they will
not make much difference.

There can be issues with some of the 2850 poweredge servers, where
they work just fine with 2GB but refuse to start at all with 4GB... 3
is the sensible MAX on these.

The biggest improvements come from ensuring that the scheduled jobs do
what they are supposed to do - daily structure, weekly contents and a
weekly reduce (even if you do not expire anything, a reduce only makes
a big difference)

Tim, thank you!
But my poor english didn't let me understand the answer for the topic 3. Can
you clear it to me?

No, you are not on the limit due to GW requiring more hardware as
such. But tuning the hardware and ensuring that it is optimised for
GW would improve things.

What is the RAID - How many disks?

A 90GB PO with 1,000,000 files is not small and if there are only 3
disks is the RAID, then while the rest of the server is fine, the disk
subsystem could do with improving.
