I'm looking for RAID options for at least 10 TB to attach to a Dell PowerEdge 2950 running RHEL 5 64-bit Server.
The system will act as a single sign-on server for XP and Linux, thus storing user's data from mounted home directories exported from the server to various workstations. It may also house a database. I'll need a storage solution starting at least 10 TB.
Most of the SAS devices I've seen go up to 2 TB. Looking at the IBM System Storage devices, for example, they offer 12 TB and up.
I'm not sure of the budget, so I'll discount cost for now.
How good are IBM's rack RAID devices? I'm just looking at their System Storage DS4xxx line.
How about EMC? Network Appliance? Clariion?
Quality of unit, reliability of unit andservice and support, overall cost of ownership? Expandability?
Thanks for any and all insights.

We have been looking at iSCSI SANs lately and with the names you mentioned, I would recommend also looking at Equallogic. The PS400E I think gets you to about the right level of storage.
DAS/NAS is a different ballgame. We are looking at SAN for virtualization purposes.

Agreed.

10.5 TB raw capasity, and can be expanded online by adding new arrays to the group.
Linear scalability for both capasity and performance.. with automatic load balancing. just add arrays. really nice.

I believe they (EqualLogic boxes) do snapshots, replication, etc. And one of their selling points is that a lot of the features and functionality are included, not an add-on product/feature/cost. We have done the price comparisons on a number of these (about half the capacity) and they are very reasonably priced.

3PAR - most innovative storage solution on the market at the moment, and thier stuff absolutely rocks. Unfortunately I don't know the costs, but technically it's brilliant.

We had lot of problems problems with IBM storage, but it's probably my personal feeling ;)

Don't have personal experience.
may I ask what kind of problem you had with IBM storages ?

Regarding DS400 - many problem with management app freezing, forcing us to reset the array (sic!) With DS4300 hotswapping controllers broke whole array. Those are probably minor problems, but we never encountered such problems with 3PAR.
Re,
We are currently using few DS4700 without any problems at all. Management application gives us no crap:) Thanks, Finnur
