Solution provides high reliability and availability of data by combining RSC Tornado AFS nodes in functional pairs. If one of the servers in a pair goes down, the second server supports functionality of its storage elements. This approach enables high-reliability storage of up to 2PB in 2U form-factor with 64x Intel® SSD NVMe drives in EDSFF.L design (so-called “ruler”). Storage nodes also include two Intel® Xeon® Scalable 2nd Generation processors, Intel® Optane™ SSD drives and Intel® Optane™ DC Persistent Memory modules. RSC Tornado AFS supports 100% “hot water” liquid cooling with record low PUE level of 1.04.
