DataDirect Claims WOS 2.0 Handles Billions of Reads/Writes

DataDirect Networks (DDN) said it is shipping the second generation of its Web Object Scaler (WOS) object-based cloud storage appliance, which is designed for Big Data environments and storage-as-a-service (SaaS) implementations.

The latest version, DDN’s WOS 2.0 system, which is available immediately, can retrieve as many as 55 billion objects per day as well as handle up to 23 billion object writes per day, the company claims.

“As more organizations move toward cloud paradigms, there is an exponential business need to globally ingest, store, process, replicate and retrieve hundreds of millions or billions of objects per hour in real time,” Alex Bouzari, CEO and cofounder of DDN, said in a statement.

Among the new features in WOS 2.0 is a “massively scalable” cloud architecture that supports more than 20 petabytes of information and hundreds of physical locations that can all be administered from a single monitoring and management console, according to DDN.

It also adds support for additional storage interfaces including NFS, Amazon S3, WebDAV, and Apple iPad and iPhone clients. WOS 2.0 provides support for asynchronous replication to speed storage and retrieval of even very large data sets, too.

Additionally, a new feature dubbed ObjectAssure provides robust data protection without requiring replication.

“With ObjectAssure erasure coding, each WOS node can withstand up to two concurrent drive failures per node without loss of data or data availability,” DDN’s statement said.

WOS 2.0 also adds cloud storage management capabilities such as multi-tenancy, bill-back, encryption, and per-tenant reporting, the statement added. It also supports multiple billing and subscription revenue models and provides usage-based reporting for pay-for-use billing.

“Unlike other cloud offerings that are built upon traditional file systems, WOS is pristine in its access and data protection performance,” Jean-Luc Chatelain, DDN’s executive vice president of strategy and technology, said.

“Further, flexible object metadata combines with these new storage interfaces to squarely establish WOS as the bridge to enable organizations everywhere to address the next wave of information proliferation,” he added.
