EMC Unveils NetWorker 8.0 With Big Focus On Multi-tenancy, Performance

Jamie Shepard, executive vice president of technology solutions at ICI, a Marlborough, Mass.-based solution provider and long-time EMC partner, said his company is hosting backups, managing them and providing 24/7 access with EMC technologies such as Data Domain.

"Getting multi-tenancy is a huge plus for EMC," Shepard said.

When EMC acquired Legato in 2003, NetWorker was in its seventh version, making the upgrade to version 8.0 seem late despite all the enhancements EMC has done over the years, EMC's Emsley said.

"During the EMC years, we have been delivering upgrades to the version 7 release that came to us in 2003," he said. "We did a lot of releases, but we didn't name any as version 8.0 until now. Looking back, we probably should have done it sooner."

NetWorker currently has an installed base of about 23,000 customers worldwide, the vast majority of which were handled by channel partners, Emsley said.

In addition to the multi-tenancy addition, EMC has enhanced Networker in three other primary areas with version 8.0, he said.

The first is an architecture upgrade to increase scalability and performance. The primary change here was to move the management of backup devices from a single NetWorker server to a distributed management system across all the storage nodes, which significantly improves scalability, Emsley said.

NetWorker 8.0 also replaces the previous flat file used to manage storage to a relational database, which decreases memory requirements as the data scales by up to 80 percent, he said.

Also new is the ability to stream backup data direct to target storage devices instead of routing that data through the storage nodes, which Emsley said cuts backup times by 50 percent or more.

The second primary area of enhancement is deeper integration with EMC's Data Domain backup and deduplication appliances that takes advantage of Data Domain Boost, a software used for improving the performance of deduplication.

The third primary area is expanded support for Microsoft applications, including supporting the virtual device interface in SQL Server to provide granular backup support.

EMC NetWorker 8.0 also provides granular recovery for Microsoft's Exchange and SharePoint, as well as support for Hyper-V virtualization technologies in Microsoft Clustered Shared Volumes, he said.
