Continuing on my set of posts related to Virtual SAN (VSAN) interoperability, let’s take a look at how vCenter Operations Manager (vC Ops for short) integrates with Virtual SAN. vC Ops version 5.8, which was released in December 2013, recognizes the VSAN datastore and can report various characteristics, as you might expect. Although vC Ops 5.8 was released around 3 months before VSAN GA’ed, this release works with ESXi 5.5U1 and vCenter 5.5U1, the vSphere release which introduced VSAN. However, this release of vC Ops does not present all the ‘storage’ metrics for VSAN like it does for datastores based on other storage types. But, having said that, there are still a number of useful vC Ops views and metrics that you might find useful which this post will cover.
First, there is the relationship view, which shows you the various ESXi hosts and VMs leveraging the VSAN datastore. This is a nice ‘getting started’ view to ensure that everything is still connected.
Well, you can still get per CPU and Memory metrics for virtual machines in vC Ops. And per VM statistics and per VMDK statics are also available for virtual machines deployed on the VSAN datastore (these per-VM and per-VMDK metrics are visible in both vC Ops and in the vSphere web client). With this information, you can identify a troublesome VM or even VMDK for instance.
Bottom line – vC Ops 5.8 can give you VSAN datastore capacity and connectivity views, as well as per-VM and per-VMDK metrics, and this will give you a good idea of how things are behaving. Additional tools are necessary to get VSAN datastore specific metrics. As I mentioned previously, I’m pretty confident that this is something which will change over time with newer releases of vC Ops.
