Going to be going the vmware esx(vsphere) route shortly to make more efficient use of systems.
I was originally looking into a Dell 2950 with a md3000i incase we do vmotion in the future. Is the md3000i quick enough to handle exchange 2003/07 for 50 users and another few intense server vm's as long as I get a nice server?
Does HP have a unit thats comparable to the md3000i that I can pair with the hp ml370?
Dell R710 (or similar) + MD3000i could be a good solutions.
And can work also with more load than 50 Exchange users
Be sure to use dedicated switches for iSCSI, follow the network topology, enable Jumbo Frame.
And make at least 2 RAID group (assigned to different MD3000i controller).
we also have 4 host (Dell PoerEdge 295) with ISCSI and Datacore running.
Our complete Terminalserver Farm an Exchangeserver (130 users) and soon our SQL Server running on it.
It is great!
If you are going with Dell, why not look at an EqualLogic PS4000X or PS4000XV? These are not software based, but are industry leading peer based storage arrays. These have link aggregation, support for lots of RAID types, snapshot backup capabilities, multiple RAID types, Active/Passive controllers. The MD3000i may support a small environment, but the PS4000 series will blow the MD3000i away in features and performance at around the same price points.
is datacore,starwind replacements for the following that I would purchase with my md3000i
Yes, for example, you take StarWind (i don`t see clear product chart on other sites) - for $3k you`ll get unlimeted storage size, with all kind of snapshots and disaster recovery functions, eitehr security options. See yourself - their product chart.
