E8 Storage delivers shared accelerated storage that incorporates NVMe SSDs into an architecture



E8 Storage announced on Monday that the company’s high-performance, high-availability shared NVMe storage solutions have achieved record-breaking SPEC SFS 2014 performance standards. Without requiring special performance tuning, E8 Storage beat all other previously published SPEC SFS test results using a single E8-D24 appliance with Western Digital NVMe SSDs in combination with IBM Spectrum Scale 5.0.

Looking deeper into the test results, E8 Storage delivered the only sub-millisecond overall response time at 0.69ms ORT.

In addition, the company’s solutions demonstrated higher IOPS and throughput than all other previous SPEC SFS2014_swbuild results. These independently validated results reinforce E8 Storage’s commitment to deliver high performance, low latency storage and simplified storage management without compromising on reliability, availability or scalability.

Driven by the company’s patented architecture, E8 Storage’s high-performance shared NVMe storage solution delivers 10 times the performance at half the cost of existing storage products. With E8 Storage, enterprise data centers can enjoy unprecedented storage performance density and scale, delivering NVMe performance without compromising on reliability and availability.

IBM Spectrum Scale helps solve the challenge of explosive growth of unstructured data against a flat IT budget. Spectrum Scale provides unified file and object software-defined storage for high performance, large scale workloads on-premises or in the cloud.

Spectrum Scale includes the protocols, services and performance required by many industries, technical computing, big data, HDFS and business critical content repositories.

IBM Spectrum Scale provides world-class storage management with extreme scalability, flash accelerated performance, and automatic policy-based storage tiering from flash through disk to tape, reducing storage costs up to 90 percent, while improving security and management efficiency in cloud, big data and analytics environments.

“This E8 solution is a great example of utilizing Western Digital’s SSDs to create a scalable, high-performance environment for data to thrive,” said Ulrich Hansen, vice president enterprise SSD marketing, Western Digital. “Western Digital’s SSDs are known for leading the industry in performance and for delivering exceptionally low command latencies for Fast Data applications. Our ability to tune and optimize performance from the raw NAND and throughout the SSD enables us to deliver the consistent performance needed to achieve this breakthrough over an industry standard NVMe interface.”

The E8 Storage appliance has 24 1.6TB drives configured as a 22+2 RAID group for data protection, with a 16+2 stripe size. The data and metadata volumes were provisioned from this single RAID group, with the volumes spanning all drives in the RAID group. All client nodes had shared read / write access to both volumes.

The cluster used a single-tier architecture. The Spectrum Scale nodes performed both file and block level operations. Each node had access to shared volumes, so any file operation on a node was translated to a block operation and serviced on the same node.

The E8 Storage controller uses a portion of internal memory to temporarily cache write data (as well as store modified data) before being written to the SSDs. Writes are acknowledged as successful once they are stored in the controller write cache, and a redundant copy is kept by the E8 agent on the host.

In the event of a controller failure, the hosts will replay the write cache for the surviving controller. In the event of a power failure, each controller has backup battery power which is combined with power-fail protection on the SSDs to ensure data is committed to SSDs prior to shutdown.

The 16 Spectrum Scale nodes were the load generators for the benchmark. Each load generator had access to the single namespace Spectrum Scale file system.

The benchmark accessed a single mount point on each load generator. In turn each of mount points corresponded to a single shared base directory in the file system. The nodes process the file operations, and the data requests to and from the backend storage were serviced locally on each node by the E8 Client Agent.
