Graid Expertise has launched the most recent model of its NVMe RAID resolution, and it’s a scorcher. As an alternative of utilizing a typical {hardware} RAID controller it makes use of a GPU to do the heavy lifting. The aim is to squeeze absolutely the most degree of efficiency from NVMe drives. Apparently, that’s precisely what it may well do.

The product is named the SupremeRAID SR-1010, and it’s a {hardware} RAID controller for NVMe and NVMeof (NVMe over fiber) storage. It’s billed as an answer that’s “designed to ship the total potential of PCIe Gen4 programs.” It does that through the use of an Nvidia RTX A2000 GPU as an alternative of a typical RAID controller. This affords it vastly extra computational energy than software program RAID or different {hardware} options. Graid claims it may well hit speeds as excessive as 110GB/s for a 512K sequential learn, with 22GB/s writes. For comparability, it says “high-end {hardware} RAID” can solely muster learn speeds of 13.5GB/s with 4GB/s writes. It could actually additionally obtain 19 million 4K random learn IOPS, in comparison with 3.5 million from different units. The cardboard runs on a PCIe Gen 4 X16 interface and helps RAID 0, 1, 5, 6, 10 on as much as 32 NVMe SSDs. It helps Linux and Home windows, however solely Home windows Server 2019 and 2022. You’ll be able to see Storage Assessment take it out of the its anti-static bag beneath.

That is an upgraded model of the earlier drive, the SR-1000. The earlier mannequin was outfitted with a a PCIe Gen 3 interface and Turing GPU. Each of these have now been upgraded, with PCIe Gen 4 and an Ampere-based A2000 GPU. It is a 70W skilled card with 6GB or 12GB of GDDR6 with ECC. The primary advantages of a GPU-based design is it’s a lot quicker than a standard {hardware} RAID controller. It offloads all I/O to the RAID card as an alternative of the CPU. Graid says a typical software program RAID setup utilizing the CPU can solely faucet between ten to twenty p.c of SSD efficiency, whereas utilizing all the CPU’s energy to take action.

Graid’s resolution is actually a singular piece of {hardware}. The location notes that NVMe SSDs are just too quick for conventional RAID adapters, and that two PCIe Gen 4 SSDs can saturate a contemporary RAID controller. Begin including extra drives to the array and also you hit a bottleneck instantly. Software program RAID works, however once more, eats up all of a CPU’s cycles and affords lackluster efficiency. This makes becoming 20-plus SSDs right into a server rack an costly endeavor. To not point out you’d have efficiency that’s lower than optimum. The SR-1010 will probably be accessible on Might 1 however pricing wasn’t launched. Based mostly on the specs, it’s most likely a kind of “if you must ask” situations.
