NW6.5 CPU / Hardware question

Hi,

I am replacing our GroupWise 8 server, which runs on NW6.5.

I recall once upon a time, that mutli-CPU or multi-core servers were not
worth a premium when it comes to seing a performance benefit? Infact, I
recall going back a few years actually disabling something in the BIOS so it
saw it as single core?

Anyway, the simple question is, will a new HP DL server with a 1 x Xeon 5520
Quad Core CPU be worth a premium when it comes to usable performance on a
NetWare server? I can save quite a bit with an older dual core model?

Thanks in advance for your suggestions to what might seem to be a stupid
question!
Thanks
Alan

That was hyperthreading, different kettle of fish.

Probably not. NW is not CPU bound, it is IO-bound, put that money into faster
disks.

Cheers, but the DL's disks would be the 10K RPM, SFF jobbies. I can't get
any better than that unless I guess I pitch for some form of attached
storage? It wouldn't hurt to see what you guys recommend! 🙂

Cheers

15k disks, raid-controller.

Re: NW6.5 CPU / Hardware question

Thanks for that, any opinions on the 6GB/s SAS disks? Unfortunately only
available in 10K RPM 146GB, so It would mean more disks for the server to
allow for expansion of the GW system.

Realistically, is a GroupWise server on Netware going to benefit from 6GB/s
disks (as oppposed to 3GB/s)?

Cheers,
Alan

Re: NW6.5 CPU / Hardware question

The RPM's are more important than the 3/6 GB's connection.

Once,, long ago,, I proved myself to eager and dumb,
I had a Seagate Barracuda on SCSI-2 and got an offer on a NEW, Wide
Seagate.. off course I switched...

Problem is; those day's Barracuda was alone with 7200rpm
so the drive I got, wide or not, was still 5400rpm..
and that,, that is VERY noticable difference...

So, from a performance p.o.v, do go for 15k drives
it is noticable speed gain there....
