Today Microsoft finally released the System Center Virtual Machine Manager Self Service Portal 2.0 (SCVMMSSP2), and after glancing over the documentation, [when it comes to scripting LUN creation] it looks to me like 2008 all over again. Evidently, the Self Service Portal team didn’t get the memo about how nobody liked “one VM per LUN” — a major flaw in the initial version of Hyper-V, for which Cluster Shared Volumes (CSVs) were the cure.
Just take a look at this excerpt from the “Extensibility Guide”:
Although the Cluster Shared Volumes feature of Windows Server 2008 R2 allows you to store more than one virtual machine on a single LUN and retain the ability to migrate individual virtual machines between hosts, the self-service portal requires a one-to-one ratio between LUNs and virtual machines.
Curiously, in a press release today, Microsoft claims that SCVMMSSP2 “…makes it easier for customers to pool, allocate, consume and manage their computer, network and storage resources — critical components for a private cloud platform.”
How will one VM per LUN make storage management easier for you?
[UPDATE: I’m told that SCVMMSSP2 works just fine with CSVs — the documentation is not to be interpreted literally, as it only applies to scripting new LUNs.]Follow @eric_gray Tweet
