The problem we have is that we are not sure what to buy. We need very quick disk access but we also need something that will work well with our existing array. We also need something that is very upgradable as we will want to replace what we already have with the new system eventually. We don't mind buying something that is half empty initially so long as there is room for expansion.
I would be really greatfull if anyone could point me in the right direction, or even supply me with some links to have a look at. I've scoured the net but can only find details on the HP XP arrays. These look great but it is always nice to have a choice.
Thanks in advance.
Solved! Go to Solution.

I personally can't complain much either about the XP solution or the EMC solution in terms of future investments and high availability/reliability.
For 24/7 however, the XP is the real solution.
Online backup, Online f/w upgrade, great performance, Dual backplane etc..
You might want to look at the Hitachi solution at www.hds.com too.. same product, different support center and software.
Later,
Bill

Re: Fast Disk Array
We use an EMC solution on a V2500.
We run 15 production databases with users spread allover Europe. We access the EMC with
fibre channel connections and have setup 4GB of cash in that solution. The databases are from 5 GB up to 70 GB in size. Nobody complains about perfoamnce issues. If you hook up something like this ( in your case preferebly an XP solution ), your problems will vanish into thin air.

Re: Fast Disk Array
My second choice would be an EMC frame. I've had recent talks with EMC and they claim to also be able to do almost all upgrades on-line now. That did not used to be the case. However, they also made some statements that were simply not true.
As for HDS, there are too many problems with HDS for my taste. If you use the HP FC interfaces with an HDS array you will only see 8 LUN's per interface. I do not like that limitation. You can get around it by using JNI Emerald interface cards. If you do that, HP will only provide support up to the interface card. You then have to rely on HDS to troubleshoot I/O problems. That is not an acceptable risk for me. I'm a big fan of single vendor solutions.
