High-Availability ZFS Partner Nexenta Achieves 1.6 Million IOPS

Nexenta Systems-Powered Storage Solution Achieves 1.6 Million IOPS

Configuration Demonstrates Power of Nexenta’s Software-defined Storage in Delivering High-end IOPS and High-availability at an Unmatched Price

SANTA CLARA, Calif., Mar 19, 2013 (BUSINESS WIRE) — Nexenta(R)Systems, the world leader in Software-defined Storage, together with its Premium Partner Area Data Systems, today announced they achieved 1.6 million IOPS (Input/Output Operations per Second) and high-availability with no single point of failure. Comparable solutions from proprietary vendors cost significantly more than the Nexenta and Area Data Systems solution and cannot guarantee high-availability. With the combination of Nexenta’s Software-defined Storage, NexentaStor(TM), and high-performance, all-flash hardware, there is now a clear enterprise-class alternative to meet the scalability demands of big data.

“Our customers can now reach well over one million IOPS and capitalize on big data opportunities without breaking the bank on proprietary storage technologies that cost hundreds of thousands of dollars,” said Bridget Warwick, Chief Marketing Officer, Nexenta Systems. “This is further proof that Nexenta’s Software-defined Storage is changing the economics of the enterprise storage market.”

Nexenta is demonstrating the 1.6 million IOPS storage configuration at Intel(R) Solutions Summit 2013 from March 19-21, 2013 in Los Angeles, Calif. Nexenta is a Silver Sponsor and will be at its booth in the storage zone to discuss the enormous opportunity for Intel channel partners to drive ideal storage solutions, powered by Nexenta, to their customers. Architecture recipes using Nexenta and Intel products are listed on Intel’s website at:

“As an ongoing Nexenta partner, we are impressed with the results that have been achieved with NexentaStor and the Intel(R) Xeon(R) E5 Server Platform,” said David Brown, director of marketing for Intel’s Enterprise Products and Systems Division. “By choosing the Intel Xeon E5 processor, Nexenta is taking advantage of key technologies like Intel(R) Integrated I/O to deliver outstanding storage performance and scalability to end-users.”

Area Data Systems leveraged its expertise with NexentaStor’s ZFS file system to achieve the 1.6 million IOPS milestone with a configuration of NexentaStor, dual Intel Xeon E5-2643 3.3GHz processors, and DataON Storage’s external storage stack, DLS-1640S (“Delivering Lightning Speed”). An elite Nexenta Partner, DataON Storage’s solution is based on Nexenta-certified, best-of-breed components: DataON 24 bay 2u JBODs, LSI Serial-attached SCSI (SAS) host bus adapters (HBAs) and switches, and STEC enterprise-class, SAS solid-state drives (SSDs). The overall cost of Area Data Systems active/active high availability 9.6TB flash-based solid state solution is an estimated $75,000.

“Our customers trust us to architect unified storage solutions that can adapt to their business today and provide the performance needed for the future. Nexenta’s Software-defined Storage changes the game by enabling Area Data Systems to offer high availability, clustered high-IOPS solutions that are more resilient and more affordable than those offered by the pure flash storage purveyors,” said Trenton Baker, vice president of business development, Area Data Systems.

1,000 RSF-1 HA Plugins for ZFS Open Storage Appliances delivered

Wilmslow, UK – February 27 2013 – High-Availability.Com today announced that it has shipped its 1,000th RSF-1 HA Plugin for ZFS Open Storage Appliances.

Since releasing it’s flagship High Availability Failover Cluster product, RSF-1 as an “HA Plugin” to the growing Open Storage market in 2009, High-Availability has now shipped it’s 1,000th deployment to a Cloud Service Provider customer in Denmark.

As well as providing seamless ZFS Pool Failover between storage controller nodes, the RSF-1 HA Plugin also manages iSCSI and Fibre Channel connections through an innovative highly available COMSTAR and ALUA interface.

Available on most Unix variants including Linux and FreeBSD, the RSF-1 HA Plugin for ZFS Open Storage has been deployed mostly on OpenSolaris, OpenIndiana, Solaris and illumos platforms across a wide range of hardware and storage subsystems and to customers across all industry platforms worldwide via a number of OEM partnerships around the world.

The most common deployments consist of 2-node Active-Active configurations on Supermicro SBB or similar storage systems with lots of built-in hardware redundancy. The RSF-1 HA Plugin for ZFS Open Storage can also scale-out beyond 2-node configurations into a variety of highly available topologies including the ability to provide distance geographical failovers.

High-Availability will soon be releasing a Stretch Cluster extension version of the RSF-1 HA Plugin that will add increased functionality to support metro cluster failover over long distances.


Coming Soon

Further development of RSF-1 Cluster continues apace with new features and extension for existing environments such as:

ALUA Support,
Perl & Python API,
Granular controller/cable/disk failure detection and customisable response,
Stand alone customisable web based GUI,
RSF-1 Configuration database with its own API,
Extended heartbeats.

iCluster for Apple MacOS X

High availability solutions developer High-Availability.Com (HAC) has introduced an innovative new port for its acclaimed RSF-1 cluster middleware solution to Apple’s MAC OS X Tiger operating system.

The port,  believed to be the first by a major third party developer to the latest version of Apple’s advanced OS, marks HAC’s entry into the Apple marketplace for mission critical applications. With its comprehensive and extremely high level of functionality, RSF-1 for MAC OS X Tiger represents a significant advance on Apple’s own IP failover, link aggregation and automatic reboot capabilities.

It also provides an important technical and marketing edge to HAC’s RSF-1 application providers, resellers, distributors and other partners, particularly those in regions of the world where the advantages of the latest Apple technology are increasingly being recognised.

An established leader in the UNIX sector where RSF-1 has been adopted by many organisations across the whole spectrum of business, industry, government and education, High-Availability.Com sells its products directly and via a global network. This includes channel partners in the UK, Europe, the US, Australia, China, Japan, Malaysia and South Korea.

One important region where HAC expects the new port to provide its partners with significant prospective added value is that of Asia-Pacific where RSF-1 is supporting mission critical systems in very diverse markets, from the Tokyo Stock Exchange and the US Navy to the Chinese Postal Service.

Partners in this region include Asgent, a Japanese developer and distributor of pioneering network security solutions and Red Flag Software which is growing rapidly to be the largest Linux company in China. Others are: KOItech and Samboo in Korea, and StorArray in Australia, Malaysia, Singapore and China. Asia Pacific regional distributor is Western Micro that is based in Hong Kong and Mainland China.

UK partners and resellers include GE Access Distribution, Acardia, DSI, Esteem, InTechnology, Maginus, Northgate Information Solutions and Phoebus Solutions.

UK application providers include ABM, Blackboard, Capita Software Services, Cedar HR, Maginus, Remedy, SITS, Steria, SWIFT and WebCT.
