AccelStor, a software-defined all-flash array provider, will be demonstrating their new NeoSapphire 3706-ES1 all-flash array at the Flash Memory Summit 2016. This high-availability all-flash array model would provide sustained 360K IOPS for 4KB random writes, with standard iSCSI over 10GbE connections, while its shared-nothing architecture would ensure no single point of failure and avoid downtime.
Even under a massive random I/O workload, AccelStor’s unique high-availability extension software, combined with the backbone of the “low-latency” InfiniBand interlink, would enable efficient data transfer between the two nodes. Therefore, incoming data can be synchronized in real time and safely preserved on both nodes, according to AccelStor.
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, the NeoSapphire 3706-ES1 can still leverage AccelStor’s proprietary software and the InfiniBand interlink’s RDMA (Remote Direct Memory Access) to ensure real-time data synchronization between storage nodes, bringing forward the recovery time objective (RTO).
The loss of a single node would not knock the NeoSapphire 3706-ES1 offline because each node is a full system with both the controller and data 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 InfiniBand interlink. AccelStor promises reduced TCA and TCO while maintaining high performance.
“It’s time for our industry to put to finally rest the outdated idea that flash arrays can offer either performance or reliability, but not both,” said Dr. Weafon Tsao, Vice President, of AccelStor – who will be giving a presentation at the Flash Memory Summit. “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 full potential from the best hardware. That’s how we’re able to provide high-availability storage device that offers astounding performance as well as great endurance and seamless reliability.”
