Vmware Using RDM's for shared Data Storage
Posted on 2008-11-16
We are trying to take this same approach. Multiple ESX servers, with mulitple hosts accessing a common "data" drive (on an EMC SAN w/ Navisphere and Access Logix) from IIS6. There is much benefit to this - a single location for deployment, easy backup, saved storage space (no need for data redundancy on a SAN) and various other items. Has anyone done this? If so, what was your approach?
We have tried to set up a file server in the middle, but are hitting a "BIOS connection limit" in Windows due to the large number of sites (and associated files) hosted on our virtual cluster.
We have tried presenting a Raw LUN to Vmware, mapping the drive in Windows as read-only, however, the obvious problem is that we don't see modifications to the file system on the windows machines unless the drive is unmounted and remounted (re-scanned).
We would like to stay away from having to push files to each esx server.
Any help would be greatly appreciated
