DL760G2 vs DL585G2?

[Andrew_346]

It's become apparent that CPU utilization is becoming an issue on one of my DL760G2 servers with 4 procs. HP sales rep is giving me a price of $27k on the 4 proc upgrade kit (p/n: 351050-B21). For under $25K, I can load up a DL585G2 with 4 - dual core procs and twice the memory all in 3U less rack space as well.

On paper, the DL585G2 looks better, hands down.

Direct CPU-memory access, faster memory, faster I/O, more internal drives, etc. Not to mention, it will be forward compatible with the new quad-core cpus when they come out.

I just need a second pair of eyes/brain to tell me that buying a new DL585G2 is the better option over upgrading the DL760G2.

And before anyone else suggests it: Yes, I have found used 4 processor kits online for much less. However, the brass are not very keen on using used equipment. They seem content with the $25-$30k cost of increasing system capacity.

quick idea

compare how you use it, all hot plug options, expansion options, PCI slots, Memory, bus split, if you don't use and you don't have any future needs in it, go with 585 or equal. DL760 designed to take internal workload and communicate with more than 2 external storage units or est.

Hotplug of PCI is not something we use. We have 3 6404 controllers connected to 3 MSA30 arrays. The DL585 can most definitely handle that and more external storage.

Has anyone purchased a DL585G2 yet? I've only worked with the G1. Great server, I can only assume the G2 is even better.

We have a SQL application that runs on a DL760 G2 (8 way w/16GB RAM)server for produciton and a DL585 G1 (4 way dual core w/16GB RAM)for test/dev. Performance wise they are neck and neck with one another.

Based on that I would go with the DL585 G2, if you do not need hot plug/raid memory or hot plug PCI.

performance/price you cannot beat the 585 G2 in this case. However, you might want to look at the 580 G4. What we have seen so far in benchmarks is that the 580 G4 will have a slight lead on the 585 G2. No real world experience yet though.

Thanks Michael.

That's exactly what I was hoping someone would be able to tell me. I think we'll go with the 585G2 and still have upgradability when the quad-cores come out.

Thanks again.

Thanks again for both replies to my question.
