EMC to buy Prisa Networks

Storage specialist EMC is to purchase storage resource management software vendor Prisa Networks for $20m (£12.8m) in cash.

Storage specialist EMC is to purchase storage resource management software vendor Prisa Networks for $20m (£12.8m) in cash.

Prisa Networks, a privately held US company, sells low to midrange storage management software. The acquisition is EMC's eighth software purchase in three years.

EMC said Prisa "brings to EMC revenue-generating products and an established OEM distribution agreement with Dell that addresses an expanding market segment" - namely, the midrange marketplace.

Erez Ofer, EMC's executive vice-president of Open Software Operations, said Prisa's software will provide those EMC midrange customers with "advanced Windows-based multivendor SAN management capabilities".

"This acquisition is an important addition to EMC's family of Intelligent Supervision products and gives us a significant time-to-market advantage, as well as the ongoing efforts of Prisa's very talented engineering team," Ofer said.

Prisa's storage management products include VisualSAN Network Manager for device discovery, management and monitoring of multivendor storage-area network (SAN) devices; VisualSAN Configuration Manager for visual identification of objects in a SAN; VisualSAN Performance Manager for performance monitoring and tracking; and VisualSAN Remote Support Suite for remote control of a SAN.

Prisa's software will initially be sold through existing OEM channels, EMC said, but will eventually be offered through additional EMC channel partners and direct sales.

EMC has also confirmed for the first time that it has enabled its network-attached storage (NAS) file server head to work on its midrange SAN array, offering a cheaper alternative to file-level data storage.

The integrated Celerra NAS/Clariion array, along with EMC's high-end Symmetrix array, can be managed from a single console using EMC's ControlCenter software management platform, giving administrators a more centralised view of their storage architecture.

"It's a level of flexibility that you get," said Tony Prigmore, an analyst at Enterprise Storage Group.

For more than a year, EMC's Symmetrix array has been able to serve up either block-level data across a SAN or files through the Celerra file head. In the past, analysts have criticised the Celerra filer, which served only the high-end marketplace, because it needed a Symmetrix array on the back end.

The Clariion array can now serve up files for about half the cost of the Symmetrix array, EMC said. The only catch is that a Celerra NAS/Clariion combination can only serve up files. By the end of the year, EMC said, the new NAS combination will also be able to serve up block-level data across a switched Fibre Channel network.
