Organizations that want to write down a considerable amount of information to disk in a brief period of time will probably be happy to listen to they will now get a subscription to one in all Nyriad’s UltraIO storage arrays, that are block storage gadgets that make the most of a GPU to speed up writes.
Nyriad is exclusive amongst storage array suppliers in that it depends on GPUs to offer an accelerated storage setting. The Austin, Texas firm acknowledged that CPUs in fashionable storage arrays are overloaded in attempting to serve each reads and writes, along with executing all the different storage administration duties (compression, de-duplication, replication, and many others.) that customers demand.
To alleviate that burden, Nyriad designed its UltraIO storage array structure to make use of a GPU to dump two duties from the CPU: write operations to the disk, and erasure encoding used throughout the HDDs on the block stage.
“We use GPUs for the write path, separate from the reads, and we use CPUs for the reads and the opposite information sources,” says Andrew Russell, Nyriad’s chief income officer. “This enables us to get a complete lot extra bandwidth, particularly on the write aspect of issues, or the ingest aspect of issues, with the array.”
Yesterday the corporate introduced that its arrays can now be obtained by means of subscriptions. As an alternative of requiring prospects to purchase the arrays outright, Nyriad will primarily lease prospects the capability they want on a 12- to 60-month foundation.
With UltraIO-as-a-Service, the array will probably be situated on premise or in a managed service supplier of the shoppers’ selecting. The client retains duty for managing the arrays, whereas Nyriad technically owns the enclosures.
On a three-year contract, the premium for the subscription providing in comparison with an outright buy plus assist is about 15%, Russell says. That’s fairly a bit lower than competing options that carry a 50% to 100% premium, he says.
“What we’re doing is delivering a cloud-like answer by way of ease of use and ease, however delivering it to them on promise,” he says.
Nyriad began life as a New Zealand firm creating storage options on behalf of the New Zealand authorities for the Sq. Kilometre Array mission that’s at the moment being developed in South Africa and Australia. The SKA mission, which is anticipated to go surfing in 2027, will generate information on the price of two petabytes per day, which necessitated a quicker solution to acquire information, however with out compromising reliability.
When the New Zealand authorities backed out of the SKA mission, Nyriad pivoted to serving industrial sectors. From the Texas tech hub of Austin, the corporate sells its software-defined storage structure, leaving the {hardware} part to its reseller companions. Nyriad first launched its UltraIO arrays about 12 months in the past, and thus far has discovered the market receptive to GPU-accelerated storage, notably in excessive efficiency computing (HPC), healthcare imaging, and media markets, amongst others.
Previous to the launch of UltraIO-as-a-Service, the corporate had two major choices: the H1000 and H2000. The 2 arrays present as much as 1.6PB and three.3PB of usable capability, respectively. The corporate makes use of business customary elements all through, together with customary HDDs versus strong state drives.

Because of the GPUs, storage throughput on its arrays can hit 20GB per second for mixed learn and write workloads. The corporate offers core block storage, whereas the distributed file techniques, equivalent to Lustre, BeeGFS, or IBM Spectrum Scale–or object storage techniques if wanted–are supplied by prospects or by the companion.
The GPUs are additionally used for erasure encoding, which offers Nyriad prospects a lift in reliability. Whereas erasure encoding is usually used on the file system or the article storage stage, Nyriad developed its personal erasure encoding expertise to use on to its block storage. Because of the GPUs, the erasure encoding can present full information parity with a a lot smaller hit on space for storing in comparison with block array suppliers that use conventional RAID.
“We get roughly 92% usable storage from each portion of the block,” Russell tells Datanami. “A typical RAIDed array will get anyplace from 50% within the worst case, whether it is doing a one-for-one. However sometimes will probably be someplace within the low 70% general effectivity ratio by way of the usable to uncooked.”
Utilizing erasure encoding on the block storage stage offers one other profit for UltraIO arrays, the corporate says: Much less impression on the CPU and the community.
“One of many issues with doing erasure code on the file stage is it’s so computationally heavy,” says Adam Roberts, Nyriad’s area CTO and head of product. “Once you get to the actually small items of knowledge, you overcome the file system’s potential to do the erasure code, they usually’ll take small information they usually’ll triple mirror them…And that’s actually, actually inefficient.
“So what we do? We do erasure code at a block stage,” he continues. “We make the most of the GPU to construct these erasure codes, and because of this, the whole lot we do is being achieved at a block stage. So now we have none of this triple mirror for some information, erasure code for others.”
Erasure coding carried out on the file stage additionally slows the native community, since erasure codes must be learn from all of the stripes in all of the completely different enclosures to rebuild information after drives go unhealthy.
“If it’s 10 enclosures, that’s a 10X hit on the community,” Roberts says. “And we take away all that by doing it down within the array.”
The erasure coding is strong sufficient that Nyriad can lose as much as 20 of the 204 HDDs throughout two UltraIO arrays and never lose any information, the corporate says.
