Server Sizing

We're going to purchase a couple servers to OES/Groupwise/Zenworks on. Can someone let me know if RAM/CPU sizes are OK?

Server1
SLES10/OES2
Zenworks Config Mgmt.
Groupwise GWIA/Webaccess
2TB Disk Space

Server 2
SLES10/OES2
Groupwise 8 (200 users) Post Office
1TB Disk Space

Would 16gb on each be enough? Supreme overkill to get 32gb?

Would dual quad-cores be helpful? Or overkill?

I'm think that may be a bit much, but we want to run strong now and in the future, as we may add 150 more staff to the Post Office.

thanks

16Gb is enough, even less would do 🙂

But I would put ZCM on a third standalone server since it's recommended to run on default port like 80/443, and it is a very "consuming" product.

For server 2 you could probably get by with 2GB. GW does not require a
lot of RAM. Rather, it is disk I/O intensive.

For just a 200 user PO, again, overkill. Single quad core is
sufficient. Heck you could probably get by with a single dual core.

A single quad core is definitely sufficient for a 350 user PO. I'd say
just get a couple of gigs of memory now since you can always upgrade
later on. Plus remember that GW is only 32-bit, so if the server is
dedicated to just GW you aren't going to benefit from > 4GB RAM. The
next major release of GW will be 64-bit, so it may make sense to at least
install 64-bit OES2 to prepare for that but you don't need to worry about
the RAM right now. Just make sure you have fast disks.

And as Thomas suggested... you may want to consider installing ZCM on a
separate server. I'm not too worried about resources, but rather having
conflicts between GW WebAccess & ZCM's web interface. If you only want
to have these two physical servers, you could install 64-bit SLES11 on
server 1 and load it with memory, say 8GB or more, then create two VMs.
One VM would be for ZCM while the other is for GWIA & WebAccess. For
simplicity sake you might want to just use plain SLES for those VMs as
well and only use OES2 for server2 which will house the PO. For the
hypervisor on server1, either Xen or VMware Server will do. You'll
probably get better performance using Xen.

Re: Server Sizing

We run our GW server on HP 385's with dual opteron cpus and 2 GB memory. Same for ZCM. Both work fine for us, but we are a small shop.

My only suggestion is to be very careful how you configure your disk space. I made the naive mistake of thinking the OES applications can use (or see) a NSS partition. This is not the case. I was burned by both ZCM and ARCserve.

ZCM is a good example. You can store image files on a NSS volume and even access them from a client computer for imaging. But try and access them from the ZCC console and you will find out you can not. This is because ZCM creates a local user "zenworks" which must have ownership of certain directories. However, since it is a local account, OES be design will not allow access to NSS from a local account.

What I did was to create a new logical partition which formatted with ext3. I then created an NCP mount so it can be accessed from the network.
