Storage player EMC has announced software that lets IT managers optimise and manage the path between servers and storage attached to a storage area network.
The enhanced version of PowerPath includes support for EMC Symmetrix and Clariion storage, application-availability features such as non-disruptive upgrades, and for the first time, volume management capabilities.
This version of PowerPath is host-based software, and it installs on a Solaris server. Later this year, PowerPath will support other operating systems and other vendors’ storage arrays. The company also plans to provide network-based volume management and path optimization software residing on Cisco’s MDS 9000 family of intelligent storage switches. The company will add data mobility to the product in the third quarter of this year to allow data to be moved around without affecting the applications using it.
PowerPath’s Volume Manager feature allocates physical storage into logical or virtual pools of storage for optimized management. It can automatically detect when storage devices are added or removed from the network, re-pooling data and resizing physical as well as logical storage volumes dynamically and non-disruptively. Mirrored copies of volumes can be imported and policies to optimize disk utilization can be set.
PowerPath's volume management features can be managed by EMC ControlCenter.
