Objective 3.1 – Managing vSphere integration with physical storage
VMware vSphere supports different types of storage, including traditional and software-defined solutions. For the physical storage, the three main categories are the following:
- Direct attached storage(DAS): vSphere supports SCSI, SATA, SAS solutions, including (in vSphere 6.5), and also NVMe solutions.
- Network-attached storage(NAS): vSphere supports NFSv3 and (starting with vSphere 6.0) NFSv4. Note that Content Library also supports the SMB protocol, but is limited to this specific function.
- Storage area network (SAN): vSphere supports several FC, FCoE, and iSCSI solutions.
Each type of storage provides different capabilities and features:
Storage type | Frontend protocols | Datastore | vSphere features |
DAS | SCSI, SATA, SAS, and so on | VMFS | VADP, RDM*, vSphere HA, and DRS** |
SAN FC | FC, FCoE | VMFS vVols | VADP, RDM, vSphere HA and DRS, vSphere FT |
SAN iSCSI | iSCSI | VMFS vVols | VADP, RDM, vSphere HA and DRS, vSphere FT |
NAS | NFS | NFS vVols | VADP, vSphere HA and DRS,... |
