PowerPath is a host-based software that provides path management. EMC PowerPath operates with several SAN storage systems, on several operating systems, with Fibre Channel and iSCSI data channels.  PowerPath 5.3 Windows is version of PowerPath that should be used for Microsoft Hyper-V.

 

PowerPath provide dynamic multipath load balancing. PowerPath distributes I/O requests to a logical device across all available paths, thus improving I/O performance and reducing management time and downtime.

 

PowerPath/VE for Windows Hyper-V provides the same multipathing functionality and load-balancing as PowerPath for Windows in non-virtual environments.

PowerPath/VE is known as PowerPath in Virtual Environment (Supported VMWare vSphere and Microsoft Hyper-V).

 

Separate license is required to use PowerPath in a Hyper-V environment. (PowerPath-VE for Microsoft Hyper-V)

 

There are additional benefits aside from the obvious performance improvements of load-balancing.

  • Clustered environments supported.
  • Streamline and Automate I/O performance
  • Simplified, single management of physical and virtual environments.
  • Automated failover.
  • Auto detect on problem paths and restore of problem paths.
