Vast Data will provide asoftware version of its product. And that’s not too much of a stretch because the all- flash “universal storage” provider that claims to be the nemesis of the hard drive is indeed built on an architecture that includes a containerized control layer.
But the move to asoftware product will not happen for some time because Vast is now focused on – in the grand scheme of things – smaller targets in enterprise storage.
At its, We asked Vast whether the company had plans to offer the container component of its product as a software-only offering.
The move would make sense because Vast’s architecture is based on providingflash and 3D Xpoint storage hardware, with a software control plane comprising stateless containerized servers with a view of all the underlying storage. The software could perhaps be re-factored to other media of the customer’s choosing.
“We have a lot of plans in this space,” saidSven Breuner. “But today, we have specific hardware dependencies at a relatively small scale. But we could with commodity capacity.
“For now, we want to focus on our specific platform, although some customers are already running Vast asas proofs-of-concept, but not many.”
Vast Data’s architecture rests on bulk but rapid access storage provided by NVMe-connected. QLC is relatively cheap for a second but is the least durable of all-flash generations and is best used for sequential (I/O). To ensure traffic is sequential, seed as much as Vast possible and put in a layer of to shape I/O into fewer, less randomized patterns.
According to Vast, 18TB of XPoint (in 12 15.36TB drives) for every 675TB of QLC makes up about 2.5% of the system by capacity.
The result is a set of storage economics and uses profiles. Vast c.laims are the death knell for the spinning diskand tiered storage. It calls itself “universal storage” and “an extinction-level event for hard drive tiering”.
Despite being comprised of all-NVMe flash, Vast claims to offer storagethat is “within spitting distance” of HDD pricing and “less than the hardware cost”, according to CME Jeff Denworth. That’s because it uses QLC for the bulk of its capacity and by use of very granular data reduction – at the – that packs more data into less space.
Vast aims to get customers to repatriate data fromand offers the promise of not dealing with capacity management. It targets use analytics and AI, HPC, transactional processing, VMware workloads, and container deployments.
Vast can provide storage for use cases in any sphere “that does not need block storage primitives”, said Denworth, namely “SCSI persistent reservations,” which is akin to file locking and allows only specified access nodes to access a.
Despite“democratizing fast access to data, “Vast provides only file and object modes, including NFS, SMB, and S3, and direct access to memory via RDMA and persistent container storage via CSI drivers.
Thewith that for now, however. File and object are the best places to place flash infrastructure,” said Denworth. “We are consciously not targeting the block storage market. File and object are the ‘easy’ button. Also, most storage, and you can do most things with the file.”
