​NetApp Highlights Dynamic Disk Pools

Facilities counting on a certain bandwidth to meet production deadlines can’t afford to have their storage systems to creep to a crawl for several days during a 6TB disk rebuild. With NetApp E-Series, they may not have to.

“Broadcasters and production facilities have discovered that dynamic disk pools (DDP) on E-Series storage systems provide more consistent video bandwidth than other block storage systems for two reasons,” states NetApp. “One is that the resiliency scheme provides drastically more consistent performance upon disk failure (50 percent more bandwidth during rebuilds than standard RAID). The other is that it dramatically reduces data rebuild time (1/8 the time of standard RAID).”

  It's a highlight for the company at NAB, as is big-data analytics workflows accelerated with E-Series enterprise building blocks.

“DDP has the advantage of randomizing writes to disk, which improves performance in the case of all-flash arrays. Analytics searches have run 50 times faster in some E-Series deployments versus commodity servers with internal drives,” the vendor states.

At the 2016 NAB Show, NetApp will promote new features in its StorageGRID Webscale (appliance or software-defined) object storage solution. A majority of the key MAM, file-delivery and archive systems have integrated to StorageGRID Webscale's Amazon S3 object interface.  StorageGRID Webscale is a next-generation solution for multipetabyte distributed content repositories. It provides erasure coding or, alternatively, automatic file copies to remote locations depending on the value of the media and the needs of the workflow.

“StorageGRID Webscale's metadata-driven information life cycle management software suite is more advanced than most object stores,” says the vendor. Additional features include self-healing data protection and tiering to either cloud or tape.

The NetApp clustered Data ONTAP operating system running on the company's FAS8000 Series of enterprise storage systems can improve video bandwidth and provides always-on operation for local broadcast-news operations, advertising sales, animation and VFX rendering, and high-speed transcoding for digital platforms. Data ONTAP can enable data mobility between private and public clouds, and its disaster-recovery software can improve overall data-management strategies.
