Hyper-V Live Migration with Direct-Attached Storage (DAS)
Reading up on Hyper-V R2 and Live Migration. Considering implementing it if we have the right hardware. Our current infrastructure includes 2 Direct-Attached Storage units connected to 4 sepearte physical servers.
My question is simple... Is Live Migration possible with a DAS or must it use some type of NAS or SAN? I get mixed information online.
If it is possible to run Live Migration on a DAS, is there some documentation somewhere on how to configure such a setup?

- Further research has lead me to believe it is not possible without iSCSI or SAN. If anyone else has different information please let me know.

You can do Live Migration without shared storage. You will need to implement a multi-site cluster with a host-based replication solution such as SteelEye DataKeeper. Here is a video which illustrates this solution.

Also, here is a blog post which details the configuration.

- Hi David,
Your product is similar to DoubleTake which we already have implemented. My questions was for a native install of Hyper-V.
Thanks for your reply.
TJR - It is very different than regular DoubleTake, but it is similar to DoubleTake GeoCluster. If you are looking for a native solution then you are correct, you will need a shared storage device that supports SCSI-3 reservations.
