HDS lifts storage performance, cuts TCO

The latest wave of product improvements from Hitachi Data Systems (HDS) cuts the total cost of ownership by up to 30% and enables performance of up to one million IOPS.

Improvements to Hitachi Unified Storage VM (HUS VM), Hitachi Unified Storage and Hitachi NAS Platform, and Hitachi Unified Compute Platform (UCP) deliver "performance, efficiency and economic enhancements across the board," HDS ANZ chief technology officer Adrian De Luca told iTWire.

• A new NAS controller for Hitachi Unified Storage and Hitachi NAS Platform delivers up to twice the performance of competing products.

HDS acquired NAS company BlueArc in October 2011, and the new 4000 series is the first generation of BlueArc products to go through HDS's hardening, testing and resilience processes. Mr De Luca described it as "a Hitachi Data Systems quality product."

The 4000 series delivers twice the IOPS of its closest competitor, has double the internal memory to support mass consolidation, and includes support for 10GB Ethernet.

Two 4000 nodes deliver the same capacity and performance as six nodes of the competing product, Mr De Luca claimed.

Furthermore, the design of the products allow for non-disruptive upgrades from the 4060 to the 4080 and on to the 40100, or from older BlueArc equipment, he said.

Consolidation and efficiency improvements translate to a reduction in the total cost of ownership of up to 30%, he added.

HDS's data deduplication capability allows the reclamation of up to 90% of storage space with no performance hit (as deduplication is performed offline) and with no storage overhead (competing systems use as much as 7% of capacity to support this feature), Mr De Luca claimed.

In addition, HDS can deduplicate up to 30PB per cluster across multiple storage tiers, compared with a 10TB limit on competing technology.

"We're seeing a lot more opportunities in the local market to 'fix the mess' [of piecemeal NAS deployments]," Mr De Luca said. A recent success was logistics company Toll which found it could reclaim storage and improve storage management after switching to HDS.

• New system software for HUS VM allows an all-flash HDS array to deliver up to one million IOPS. Mr De Luca said this means HDS's midmarket product is now able to approach enterprise-class performance.

While not all workloads require this level of performance, he suggested the new configuration is relevant to large VDI farms (as in thousands to tens of thousands of desktops) and the processing of machine-generated data (such as genome sequencing) which requires the write performance that all-flash storage can deliver.

Up to 154TB of flash storage (pictured) can be used with a single controller, and the new system software is said to provide up to double the storage efficiency of commodity solid state drives while reducing the cost per I/O by up to 60%.

Last year, HDS announced its own technology for flash-based storage, featuring a custom ASIC for wear levelling (allowing the company to offer a five-year endurance guarantee), greater performance, and increased storage density for a given footprint.

HDS all-flash systems are gaining traction in the local market. For example, HDS is a preferred supplier to the federally-funded Research Data Storage Infrastructure project, and the South Australian node is all-HDS with another announcement expected soon, Mr De Luca said.

• Changes to Hitachi UCP include new prebuilt configurations for VMware, Hyper-V, and Oracle products.

UCP Pro for VMware vSphere is a complete turnkey system including software licences.

UCP Select for Microsoft Private Cloud (ie, Hyper-V 3.0) and UCP Select for Oracle Database Real Application Cluster include hardware and a reference architecture, but leave the customer to add software licences.

The Hyper-V configurations scale to tens of thousands of virtual machines, and includes replication for live migration between UCPs.

The Oracle RAC configurations allow up to four blades (80 cores) to be bridged together to present to the software as a single mainframe-class computer, and the use of accelerated flash means they can he used to run high workload data warehouses, Mr De Luca said.

The systems are all integrated with the relevant management tools, such as Oracle's RMAN.

By reducing deployment times, simplifying management and improving utilisation, UCP systems are said to reduce total cost of ownership by up to 30% over four years.

HDS vice president of storage platforms product management Roberto Basilio said "The technologies we are announcing today redefine the economics of storage by delivering opex savings that are essential to a business's bottom line.

"By eliminating performance hiccups associated with disparate architectures and information silos in the data center environment, HDS sets a flexible yet powerful foundation for private cloud and big data platforms that helps to accelerate insight, improve decision-making and free up resources for customers to innovate with information."
