Low-cost QLC flash saves 85%.

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.

Next-gen erasure coding saves up to 66%.

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 global data reduction saves another 50-90%.

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

QLC Has Significant Challenges That Must Be Innovated Around.

challenge
QLC Endurance is 1/100th of Previous-Generations of Flash

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.

Solution
Global QLC Flash Translation Eliminates Write Amplification

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.

Challenge
QLC Write IOPS Are 98% Lower Than Reads

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.

Solution
A Distributed XPoint Write Buffer To The Rescue

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.

Challenge
QLC Drives Are Single-Ported

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.

Solution
VAST Intelligent Enclosures Dual-Port SSDs in Software

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

Eliminate the 5-YearHDD refresh cycle.

Get 20x more endurance from low-endurance QLC flash.
