It depends on how a given array is configured. Q: How many Storage Containers can I have per storage array? This abstraction can be used for better managing multi-tenancy, various departments within a single organization, etc. Moreover, the Virtual Datastore provides logic abstraction for managing large numbers of vVols. The Virtual Datastore is a key element and it allows the vSphere Admin to provision virtual machines without depending on the Storage Admin. vSphere will map the Sstorage Container to Virtual Datastore and provide applicable datastore level functionality. Storage containers are setup at the array level and associated with array capabilities. Q: What is a storage container and how does it relates to a Virtual Datastore?Ī vVols Storage Container is a logical abstraction on to which vVols are mapped and stored. For more information, see the Working with Virtual Volumes section of the VMware vSphere 6.0 Documentation. They are intended to replace the concept of LUNs and mount points. Protocol Endpoints are compliant with both, iSCSI and NFS. All paths and policies are administered by protocol endpoints. Protocol endpoints are the access points from the hosts to the storage systems, which are created by storage administrators. In addition, VASA commands to the VP can be used to snapshot vVols, revert a vVol to a previously created snapshot, as well as change the storage profile of an existing vVol. The VP is used to set up access to a vVol, communicate with VC and with ESX hosts as vVols are used, and ultimately release vVols. The VASA Provider or VP is the endpoint of the out-of-band management connection. Instead, hosts access vVols through an intermediate point in the data path, the so-called "I/O Multiplexer" or "Protocol Endpoint" (PE) which is a SCSI target in the case of block-based vVols storage and an NFS mount point for NAS-based vVols storage. Storage arrays or servers are designed to manage all aspects of vVols storage and vSphere hosts have no direct access to a vVols storage. vVols are designed to work equally over SCSI (FC, iSCSI, or FCoE) or NAS protocols. Using Storage Policy-Based Management (SPBM), VMs are provisioned with storage from vVols based arrays or servers through the mediation of a VASA Provider (VP) which provides an out-of-band interface for managing vVols based storage. VVols are a new model for provisioning, managing, and accessing virtual disks for vSphere VMs. Q: What are VMware vSphere Virtual Volumes (vVols)?
