When we host accessing the Data Storage for Redundancy, Load Balancing, Application Priority, Failover, there is a host software that interfaces with storage to perform the above functions.

I have personally used quite a few of Storage Failover software’s, do believe Powerpath is one of the strongest one with the closed competition from Veritas – DMP.

Some of the key industry leaders in the Host Failover Software are

EMC Powerpath
Symantec DMP: Dynamic Multi Pathing
HP: Secure Path
Hitachi HDLM: Hitachi Dynamic Link Manager
IBM MPIO: MultiPath I/O
SDD: Subsystem Device Driver

Again the closest competitor to EMC Powerpath would be Symantec DMP.
