Pillar beefs up disaster recovery, QoS

-- Pillar Data Systems today released additions to its AxiomONE operating software that bring a variety of replication, performance and data protection features to the Pillar Axiom unified storage platform.

The AxiomONE software enhancements include native array-based replication for both SAN and NAS traffic, enhanced Quality of Service (QoS) for storage tiers, and a new component that speeds the rebuild time for failed drives.

On the replication front, Pillar has added native asynchronous replication for both SAN and NAS data on the same Axiom platform. Bob Maness, Pillar's vice president of worldwide marketing and channel sales, says AxiomONE Replication requires an optional software license and is priced $1,000 per replicated terabyte. Pricing for AxiomONE replication is capped at a maximum of $100,000.

Maness says most of Pillar's replication customers replicate anywhere from 20TB to 30TB of data.

Pillar has also brought QoS down to the storage tier, allowing for QoS priority bands to operate within each storage class or media type, whether it is made up of Fibre Channel, SATA or solid-state disk (SSD) drives.

Pillar's QoS technology uses application profiles to automatically adjust CPU, cache and network resources to boost performance.

"We essentially take our five service levels and apply them inside each media type. Having QoS within each storage class lets users split up different operations of an application in different QoS bands to achieve optimum performance, capacity, CPU and cache utilization," says Maness.

Also new to AxiomONE is a feature called Pre-emptive Copy, which senses "suspect" drives in the Axiom storage pool and kicks off a copy function that begins the rebuild process before a drive failure.

Maness says Pre-emptive Copy hastens drive rebuild times by doing the bulk of the work before a failure occurs, using a simple copy instead of a rebuild of the drive contents.
