Today DataDirect Networks announced DDN Flashscale, a new family of all-flash scale-out and scale-up storage solutions, which delivers the highest performance and capacity in a cost-optimized and feature rich platform designed for Enterprise Big Data and Analytics, Web Scale Cloud, and HPC environments. DDN Flashscale delivers an ultra-dense, high performance and low latency network attached shared flash storage solution for home directories, data analytics, databases and computational applications. DDN’s built-for-flash custom architecture unlocks the value of each SSD in the solution by aggregating the full performance of each device and delivering the performance over the low latency embedded PCIe Gen3 fabric to performance hungry applications. DDN Flashscale’s fast embedded PCIe fabric delivers full native performance and extreme low latency from 48 NVMe or 72 SAS or any mix of SSDs while offering cost optimized sub $1/GB all-flash storage up to 576TB, 6 Million IOPS and 60GB/s per 4U node.
