This appliance is SMB (Small-Medium Business) VMware vSphere Storage Appliance (VSA)
In VMware vSphere 5.0 (vSphere)
VMware is releasing a new software storage appliance to the market
called the vSphere Storage Appliance (VSA)
This appliance provides an alternative shared storage solution for
small-to-medium business (SMB)
customers who might not be in a position to purchase a SAN or NAS array for
their virtual infrastructure.
Without shared storage configured in a vSphere environment, customers have not
been able to exploit the unique features available in vSphere 5.0,
such as vSphere High Availability (vSphere
HA), vSphere vMotion (vMotion),
and vSphere Distributed Resource Scheduler (vSphere DRS). The VSA is
designed to provide shared storage for everyone.
This paper presents an overview of the VSA architecture,
deployment of a VSA storage cluster, and basic
monitoring and managing.
