With a new approach to Global QLC Flash Translation, VAST clusters extract 20x more longevity from low-cost QLC flash as compared to what legacy architectures can achieve.
VAST’s Locally-Decodable Erasure codes deliver 60 million years of resilience, while only requiring 3% overhead for data protection, breaking the tradeoff between resilience and cost.
New Similarity-Based Data Reduction combines the fine-grained pattern matching of compression with the global approach of deduplication, delivering unprecedented storage efficiency.

QLC Flash Translation
Quad-Level Cell (QLC) flash, the newest generation of flash, features the highest NAND capacities by fitting four bits per each flash cell. While this density enables lower manufacturing and therefore customer costs, QLC has a number of disadvantages that must be innovated around to make it possible to field QLC in dynamic application environments for over a decade of system life.
The physics of QLC NAND make it impossible to overwrite devices more than a few 100 times. This problem compounds with the fact that the internal flash geometry wants to be written to in many-100MB blocks. If QLC drives aren't written to properly, the drives can wear themselves out in short time through their own block management gyrations.
VAST's cluster architecture always writes in full QLC erase blocks, thereby avoiding the complication of dealing with the controllers of these commodity drives. VAST Clusters leverage the insights gained at the file and object level to inform the data placement engine such that long-term and short-term data are never co-located in large QLC blocks, making it possible to eliminate internal write amplification and get 20x more longevity from commodity QLC flash.
The process of writing to QLC silicon is much more complex than the process of reading. Without some 'buffer' to absorb writes and sequentialize them down to QLC NAND, application writes suffer.
A thin layer of XPoint provides VAST clusters with a global write buffer that shields applications from the write IOPS performance deficiencies of QLC flash, without incurring the cost and complexity that otherwise comes from DRAM-based writeback caching.
Low-cost QLC SSDs were designed for hyperscale operators that spray mountains of SSDs across shared-nothing storage servers. While this works for customers that need 100s of Petabytes, it doesn't work for smaller deployments where HA enclosures can provide superior efficiency.
Intelligent NVMe enclosure software can remap the PCI lanes of single-ported NVMe drives on the fly, without requiring interposers, instantaneously recovering from any I/O path failure within a VAST Enclosure.
10-Year Longevity
VAST's Universal Storage is backed by a 10 year warrantee and a flat+fixed price for maintenance that protects customers from the classic maintenance uplift that legacy vendors impose on customers in the later years of a system's lifespan.

Global Data Protection
VAST's new Locally-Decodable erasure codes break the longstanding cost vs. resilience tradeoff. VAST’s new data protection codes can support more concurrent failures in a failure domain than other systems while also bringing the system’s overhead down to just 2.5% (vs. other systems that carry 30%-66% overhead). The speed and efficiency of VAST's data protection architecture result in a 60 million year MTTDL (Mean Time to Data Loss)... and because everything is fail-in-place, customers never need to run into the data center with their hair on fire.
VAST's new Locally-Decodable erasure codes solve the fundamental problem of data recovery for large write stripes, by locally-decoding a rebuild event. Rebuilds are performed in a fraction of the time of conventional erasure codes, and VAST's fail-in-place, declustered, approach to erasure coding brings all of the system resources to bear during a rebuild event in order to dramatically reduce the time to recovery and increase resilience.
Data protection codes scale across VAST enclosures and become more efficient as clusters scale. At scale, these codes require as little as 2.5% overhead... providing more cluster free space from your VAST investment.
Global Data Reduction
VAST’s new approach to data reduction enables unprecedented storage efficiency for nearly any data type, further bringing down the cost of the system and tipping the economic scales in favor of flash.
