AccelStor Will Debut NeoSapphire 3706-ES1 All-Flash Array

AccelStor, Inc. will be demonstrating the NeoSapphire 3706-ES1 all-flash array at the Flash Memory Summit 2016.

It is officially launched and this HA all-flash array model provides sustained 360,000 IO/s for 4KB random writes, with standard iSCSI over 10GbE connections, and its shared-nothing architecture ensures no single point of failure and avoid downtime. In addition, The company will showcase FlexiRemap technology on a new NVMe array platform at the event.

Dr. Weafon Tsao, VP, AccelStor, who will be giving a presentation at the Flash Memory Summit, said: “It’s time for our industry to put to finally rest the outdated idea that flash arrays can offer either performance or reliability, but not both. At AccelStor, our arrays are designed from the ground up for flash, and our software-defined approach gives us the flexibility to respond swiftly to changing market demands, and extract the potential from the best hardware. That’s how we’re able to provide HA storage device that offers astounding performance as well as great endurance and seamless reliability.”

360,000 IO/s high performance and real-time data synchronization reliability
The 360,000 IO/s NeoSapphire 3706-ES1 offers both responsive speed and dependability. This HA storage array achieves reliability and fault tolerance, with almost zero downtime, based on a solid shared-nothing architecture and the active-active failover design. Two complete nodes in a single appliance ensure there’s no single point of failure (NSPF).

Even under a massive random I/O workload, firm’s HA extension software, combined with the backbone of the low-latency IB interlink, enables efficient data transfer between the two nodes. Therefore, incoming data can be synchronized in real time and safely preserved on both nodes.

The NeoSapphire 3706-ES1’s redundant design takes flash-drive or critical hardware-module failures in its stride. In addition, when fault recovery is required, it can still leverage company’s proprietary software and the IB interlink’s RDMA to ensure real-time data synchronization between storage nodes, bringing forward the RTO.

Zero downtime – True HA solution
Some storage solution vendors may claim their products offer HA when in fact they only offer partial redundancy. For example, these products may contain only one shared storage subsystem. The entire device drops offline if this single critical unit fails. The loss of a single node cannot knock the NeoSapphire 3706-ES1 offline because each node is a full system with both the controller and storage. The active-active failover design of the NeoSapphire 3706-ES1 means that both nodes operate simultaneously. If one node fails, the other seamlessly takes over, so there is almost zero downtime – the nodes communicate with each other via a high-speed, low-latency IB interlink. The firm promises reduced TCA and TCO while maintaining high performance.

FlexiRemap unlocks potential of flash
Alongside the NeoSapphire 3706-ES1, the company will also be showcasing a new NVMe flash array at the Flash Memory Summit 2016. Both these devices are equipped with firm’s FlexiRemap software-defined flash technology. With FlexiRemap, data is protected, drive endurance is improved, and random-access speed is accelerated. The technology remaps random data writes as sequential writes when required, avoiding overheads and extending SSD life by eliminating unnecessary writes and erases. The technology achieves sustained performance and reliability even in the random-access scenarios typical of enterprise storage needs. Thanks to the global wear-leveling algorithm, FlexiRemap arrays have at least twice the endurance than typical legacy RAID-5 flash systems, and the technology is exclusive to the company.
