Stateless VAST Servers, which run in VAST Server Containers, provide all the storage protocol and management services in a VAST ClusterA VAST Cluster is the set of VAST Servers and VAST Enclosures that make up a single management domain and namespace..
Each VAST Server can directly access all the Optane3D Xpoint is a new non-volatile memory technology that has much lower latency and much higher endurance than NAND Flash. Optane is Intel’s trade-name for SSDs using 3D Xpoint as their storage media. VAST Universal Storage Systems use Optane SSDs to store system and element store metadata as well a... More and QLCQLC flash stores four bits in each flash cell as 16 different charge, or voltage, levels. Compared to less dense flash technology like MLC (2 bits/cell) and TLC (3 bits/cell) QLC flash has lower cost/bit and lower endurance. SSDs in all the VAST Enclosures in the VAST Cluster.
