VMware vMotion and Snapdrive

Currently Being Moderated

Where do I start???


I have read quite a few documents out there on this topic so I am aware of the usual issues people may have.  I would just like to know the following:


1)  I am going to be using SMSQL including SnapDrive (dont think you can use SMSQL without Snapdrive actually).  If I set this up on a VM within my VMware environment, will I have issues with vMotion?  As I understand it as long as an ESXi host can see the LUNs vMotion should work.  Does this mean I have to mount the iSCSI LUNs in VMware as well as the Windows machine?


2)  What Fractional reserve and snapshot reserve should I set on the volume housing my LUN which I am mapping using Snapdrive?


Thanks guys

    Hi Gav,


    1) VMotion will work. SnapDrive (since version 6.2?) integrates with vCenter, so you provision your LUNs (as RDMs) in one place only.


    2) The 'modern' (official) recommendation says set fractional reserve to 0% & use volume aoutosize & snap autodelete. The 'old school' says set it to 100% - less usable storage (a LUN can't be bigger than 50% of the size of the volume), but still perceived by many folks ad more secure.
