Which two storage technologies can an administrator use to deploy the Virtual Machine File System (VMFS)? (Choose two.)
Which two storage technologies can an administrator use to deploy the Virtual Machine File System (VMFS)? (Choose two.)
The Virtual Machine File System (VMFS) can be deployed on block-based storage technologies, which are necessary to support VMFS. Fibre Channel storage and iSCSI storage are both block-based storage technologies and are therefore appropriate for deploying VMFS. Other options, such as vSAN storage, Virtual Volumes storage, and NFS storage, do not meet these requirements as they are either object-based or file-based.
A & E are correct. VMFS can be deployed on three kinds of SCSI-based storage devices: • Direct-attached storage • Fibre Channel storage • iSCSI storage
In order for a filesystem to be made, the underlying storage must be block-based. VSAN and virtual volumes are object-based and NFS is file-based. Hence, A & E.
Again - only block storage supported
A&E Optimizes Virtual Machine Access VMFS provides the SCSI access layer for virtual machines to efficiently read and write data on the underlying disk. It uses adaptive block sizing for large I/Os, and subblock allocation for small files and directories. VMFS is rigorously tested and certified for a wide range of Fibre Channel and iSCSI storage systems, and it is optimized to support large files while also performing many small concurrent writes.
AE Yes.
