Path failover - ETERNUS Multipath Driver

In combination with ETERNUS Multipath Driver, ETERNUS disk storage systems support high availability by use of multiple paths between a server and an ETERNUS disk storage system unit. In the event of a path failure, the ETERNUS Multipath Driver software automatically switches paths, ensuring non-stop operation. In addition, the Load Balance feature enables load balancing by distributing the I/O requests evenly across the multiple paths. This results in optimized application response.

ETERNUS Multipath Driver

Benefit

  • Continuous access even during a path failure (automatic failover)
    By connecting multiple paths between servers and disk storage systems, a standby path can takeover operation if a failure occurs in the original path.
  • System performance improvement through load balancing
    Bottlenecks can be eliminated by using all available access paths simultaneously. This delivers improved system performance as well as failover capability.
