Orchestration of Storage (VSAN)
Virtual Storage Area Network (VSAN) is a construct of locally attached disks assembled into a fully connected array of storage. VSAN is included into the kernel of later versions of vSphere (5.5 and newer) and allows the locally attached storage to be pooled and presented as a single datastore with the hosts connected to it.
VSAN requires a cache tier as seen in the graphic as an SSD and a capacity tier as displayed as a HDD. This delivers fantastic performance and can be run on essentially commodity storage. This provides a huge cost benefit and gives the company a means to build a highly scalable solution for a remote office/branch office or running an entire infrastructure. It also simplifies the administration of the storage for the typical Virtual Infrastructure and gives an almost set-it-and-forget-it type of interface.
Setting up a VSAN is a fairly simple process as it has an attached disk to the host. Examining the Hardware Compatibility List (HCL)...
