The MD1000 is a disk enclosure and requires a SAS raid card in a server to work.
The MD3000 is the same chassis but has integral raid contollers, it requires SAS Hba's in the server(s), you can expand the 3000 by daisy chaining MD1000's.
An MD1000 can't be used for clustering and has no redundancy other than raid and 2 powersupplies. The MD3000(i) supports redundant connections for when 1 raid controller fails, and also supports clustering.
