Ever thought, how to consolidate and utilize all that extra local storage on your VMware hosts? After all, that storage is just sitting there and can be used for storing unnecessary VMs, ISOs, templates and other non-essential stuff. One of the main issues that prevents IT managers from using local storage is its unavailability to other hosts in and across clusters. However, LeftHand's P4000 vApp for Virtual SAN Appliance solves that issue and allows other hosts in the cluster to see the local stores as iSCSI LUNs which can be mapped to each host as shared datastores.
This is very useful because for small shops that don't have the budget or need to buy expensive SAN or NAS devices can actually use this vApp to present local storage on hosts as shared storage and use high availability features like HA, DRS, Vmotion and others.
