Door BCONN professional Dennis van der Aalst:
Recently I had the pleasure (again) of designing and building a vSphere Metro Storage Cluster (vMSC).The last time I did this the environment was built using vSphere 6.0 and I used HPE StoreVirtual Storage, see my previous blog on https://dennisvanderaalst.com .
This time the customer already had a storage solution in place: HPE 3 PAR F7400. And the customer wanted me to design and build a vMSC using the latest available version. Which was vSphere 6.5 at the time.
Normally I go through the available best practices from all relevant vendors, in this case VMware, HPE and Dell because we are using PowerEdge servers from Dell. I was a bit disappointed to find out there are no up to date best practices from VMware regarding vMSC and vSphere 6.5. I contacted VMware and they confirmed there is no whitepaper regarding vMSC available for vSphere 6.5.
The reason for this blog is that I encountered something I didn’t expect with a new vSphere 6.5 DRS feature “VM Distribution”. But before we dive into that let me first explain what we tried to achieve.
