1. Re: Data Store Clustering with Local Disk
Richardson Porto Apr 4, 2017 3:28 PM (in response to jahanzaib)Assuming you're talking about Datastore Cluster, the best practice is to have all volumes on a shared storage, this way the vSphere Storage DRS will be able to balance virtual machines between datastores automatically. If you use local disks, the virtual machine files availability will be affected in case of a host failure.

2. Re: Data Store Clustering with Local Disk
jahanzaib Apr 4, 2017 3:34 PM (in response to Richardson Porto)For now I have only local disks availability which are mounted with 4 running blades. So can we do the clustering on these data store?

3. Re: Data Store Clustering with Local Disk
Richardson Porto Apr 4, 2017 3:45 PM (in response to jahanzaib)If you plan to have High Availability is not a good idea to use local disks, since that disks are not shared between hosts, and if a single host fails, all virtual machines stored on local disk of that particular host will become unavailable.

5. Re: Data Store Clustering with Local Disk
Richardson Porto Apr 4, 2017 5:08 PM (in response to jahanzaib)The advantage of a datastore cluster is to manage and manage them as a single entity and of course provide load balancing based on space and/or I/O latency and create anti-affinity rules.
