Abstract
Providing active-active failover capability to non-failover capable direct-attached storage (DAS) servers including connecting a first and a second non-failover capable direct-attached storage (DAS) servers to a shared storage pool via an expander that supports storage zoning, configuring a first storage zone including the first DAS server and a first portion of the shared storage pool, configuring a second storage zone including the second DAS server and a second portion of the shared storage pool, detecting that the second DAS server has failed, zoning out the second portion of the shared storage pool and mapping the second portion of the shared storage pool to the first storage zone.
