VSP High Availability Overview
SteelHead EX provides high availability for VSP and SteelFusion. High availability can be deployed in any of the following modes:
• Integrated mode - SteelFusion, VSP, and virtual machines operate on a single SteelHead EX, which acts as the active device. A second, passive, SteelHead EX acts as the failover device.

• Dedicated mode - One active SteelHead EX hosts SteelFusion while a separate active ESXi server hosts virtual machines and connects to the SteelHead EX. A passive SteelHead EX and a passive ESXi server are also deployed and act as failover devices for SteelFusion and virtual machines, respectively.
