[quote=“mrtoddh, post:5, topic:575”]Like Southpaw018 stated the DroboPro is a DAS device not a NAS. You need to make sure that only one device uses each LUN at any given time. So, you could connect 4 ESX boxes to 4 sepereate LUNs (volumes) using port 3261.
One caveat… When connecting to the DroboPro using port 3260 or 3261 all volumes are available. In Windows all LUNs are connected and added as Hard Drives and available in Disk Management. There is no way that I am aware of to connect to an individual LUN in Windows. Of course ESX will see all LUNs but only the LUNs you are interested in and specify are added to your storage pool.
Quick correction. To your first paragraph about DAS and NAS, this is not entirely correct. The ESX VMFS filesystem as implemented on VMware is intended for failover clustering. Because of this, it is correct to connect up to 4 ESX boxes to the SAME LUN.
To your second paragraph. This is not too difficult. I have a Windows Server and a Linux Server hooked up to my DroboPro. This is how I did it. Just set up the Windows Server first. Go into the Disk Manager and right-click on any volume you do not want to access in Windows, and select “Offline”. They will no longer be accessed from Windows. You are free to access those ones from Linux or ESX or whatever. Note that this “offline” selection in Disk Manager is only available on Windows Server. If you are trying to do this in Vista, it can still be done, but you need to go into the device manager, right-click on the drives you don’t want to access in Vista, and select “Disable”. Works the same way. This keeps across reboots too. Quite reliable.
