Graid Know-how has launched the newest model of its NVMe RAID resolution, and it’s a scorcher. As a substitute of utilizing a typical {hardware} RAID controller it makes use of a GPU to do the heavy lifting. The purpose is to squeeze absolutely the most stage of efficiency from NVMe drives. Apparently, that’s precisely what it may well do.

The product known as 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 by utilizing an Nvidia RTX A2000 GPU as a substitute of a regular 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 may additionally obtain 19 million 4K random learn IOPS, in comparison with 3.5 million from different gadgets. 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 under.

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. This can be 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 conventional {hardware} RAID controller. It offloads all I/O to the RAID card as a substitute of the CPU. Graid says a typical software program RAID setup utilizing the CPU can solely faucet between ten to twenty % of SSD efficiency, whereas utilizing all the CPU’s energy to take action.

Graid’s resolution is definitely a novel piece of {hardware}. The positioning 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 might be out there on Might 1 however pricing wasn’t launched. Primarily based on the specs, it’s in all probability a type of “if it’s important to ask” situations.
