An Intellyx Brain Candy Brief
VAST Data delivers massively scalable, all-Flash storage based on an innovative, disaggregated and ‘shared everything’ data architecture.
Under the covers, VAST implements federated, stateless containers that see all the underlying data while operating independently, thus preventing partition intolerance issues that limit data consistency.
VAST leverages the Non-Volatile Memory Express (NVMe) protocol over Fabrics (NVMe-oF). NVMe is a standard interface specification that supports solid state drives (SSDs), in particular, flash storage. NVMe-oF, in turn, extends NVMe to Ethernet while optimizing the CPU utilization of host servers.
VAST Data fully leverages these protocols to deliver highly resilient hybrid (cloud-based and on-premises) storage.
In addition to RAID-style resiliency, storage nodes need not communicate with each other. This lack of east-west traffic adds to VAST’s scalability and the efficiency of its recovery – leading to faster rebuilds after drive failure and better data reduction than alternative solutions.
The result is a single, arbitrarily large volume that enterprise users can share without concerns for scalability, data consistency, or recovery from failure, with better ransomware protection than traditional immutable backup approaches.
