Example text

In this case, the problem is being caused by not storing the virtual machine on two separate LUNs in two separate groups. The impression from the vSphere client would be that the virtual machine is being stored at one VMFS datastore. Unless you were looking very closely at the storage section of the vSphere client you might not notice that the virtual machines’ files were being spanned across two LUNs in two different groups. This wouldn’t just cause a problem with the virtual machine; more seriously it would completely undermine the integrity of the VMFS extent.

It is possible to accept the default at this stage, and change it later once you have a better handle on your storage consumption over time. 5 EqualLogic has, for some time, supported thin provisioning that can help with volume sizing questions. Remember, this allocation of snapshot space will not influence your day-to-day usage of VMware SRM. This reservation of snapshot space comes from an allocation that is separate and distinct from that used by VMware SRM. So it’s entirely possible to set this as 0% on volumes where you don’t envisage yourself creating snapshots of your own, as would be the case with archive or test and development volumes 3.

This lack of awareness could mean you create an extent, which includes a LUN, which isn’t even being replicated. The result would be a corrupted VMFS volume at the destination. Of course, if you are using the new VR technology this issue is significantly diminished, and indeed the complexity around having to use extents could be mitigated by adopting VR in this scenario. Clearly, there will be times when you feel pulled in two directions. For ultimate flexibility, one group with one LUN allows you to control the replication cycles.
