Shared storage provides shared file services by using file system or RBD storage pools.
You must deploy shared storage if you want to provide any services that require live migration of VMs, including HA, DRS, and DPM services. The use of shared storage accelerates VM migration, because VMs can be moved around the cluster without the need to move storage resources.

Type: Type of the shared storage.
Target Path: Mount point of the shared storage on the physical host.
Total: Total storage size.
If the storage pool is an RBD storage pool, the size of the storage pool is calculated as follows:
Suppose that the block storage data pool corresponding to the RBD storage pool is Pool A.
If Pool A uses a replication redundancy policy, the RBD storage pool size = raw capacity of Pool A/replica quantity.
If Pool A uses an erasure coding redundancy policy, the RBD storage pool size = raw capacity of Pool A × data block quantity/(data block quantity + parity block quantity).
The raw capacity of a storage pool is the capacity sum of all normal disks in the pool. The actual size of an RBD storage pool might be smaller than the calculated size because of metadata cost. If the distributed storage system uses metadata separate deployment, the raw capacity of a storage pool is the raw capacity of its metadata pool. For example, in ONEStor, the disk pool of a storage pool is the metadata pool of the storage pool, so the raw capacity of the storage pool is the raw capacity of its disk pool.
Allocated: Total virtual storage size that is allocated to VM disks.
Available: Available storage size.
