Issue/Introduction

This article describes supported configurations for vSphere Metro Storage Cluster (vMSC) environments relating to vSphere Storage DRS (SDRS) and vSphere Storage I/O Control (SIOC).

VMware vSphere ESXi 5.0
VMware vCenter Server 6.7.x
VMware vCenter Server Appliance 6.7.x
VMware vSphere ESXi 5.1

Resolution

In a vMSC configuration, volumes are distributed across locations or sites. VMware supports Storage DRS in uniform and non-uniform configurations with restrictions, these restrictions apply:
  • SIOC is not supported.
  • SDRS is only supported when the IO Metric function is disabled.
  • To control what point in time the migrations occur, run SDRS in Manual Mode.
  • Each location or site needs a datastore cluster formed from stretched datastores and with site bias to that particular location or site.
     
    • For example:

      Site A has Datastore Cluster A, which contains all stretched datastores with bias to Site A.
