Viking Know-how this week launched its new VT-PM-series persistent reminiscence drives that are available in 2.5-inch U.2 form-factor and help hot-swapping functionality. The drives are designed for functions that require a really excessive efficiency and a vast endurance, corresponding to high-performance journalling and log storage for databases and filesystems. One of many key benefit of the drives when in comparison with common NVDIMMs is help for hot-remove/shock hot-add in addition to an industry-standard interface.
Viking’s VT-PM8 and VT-PM16 persistent reminiscence drives use the U.2 interface working in twin port 2×2 or single port x4 mode. The storage options are outfitted with Eight GB and 16 GB of DDR4-2400 RAM that has a just about limitless endurance (properly past that of NAND and even 3D XPoint) in addition to Eight GB and 16 GB of non-volatile NAND that’s used to protect knowledge within the occasion of energy failure. The SSDs are outfitted with an inner supercapacitor energy supply that kicks off routinely when the primary energy is misplaced to switch knowledge from DRAM to flash utilizing the Flush-to-Flash firmware.
The drives are primarily based on an structure that may work with each DDR4 reminiscence and NAND developed by Radian Reminiscence Techniques (it’s unclear whether or not Radian makes use of an FPGA, or an ASIC). The structure is absolutely compliant with the NVMe 1.zero command set that lets functions to entry knowledge on the VT-PM persistent reminiscence drives through common block or programmed I/O byte addressable entry with none particular necessities. To make sure knowledge integrity, the silicon designed by Radian contains a 64-bit knowledge/Eight-bit ECC code to detect double bit errors and proper single bit errors in DRAM. Moreover, the answer helps LDPC to make sure robust endurance and excessive efficiency of flash. As well as, Viking’s VT-PM drives help BIST (built-in self-test) that displays parts well being and environmental standing after which studies outcomes to host programs.
In the case of efficiency, Viking’s VT-PM drives must be fairly quick because of a PCIe three.zero x4 interface (helps 32 Gb/s ‘uncooked’ bandwidth) and utilization of comparatively quick DDR4 DRAM. As for energy consumption, the drives want as much as 13.5 W when working in addition to 17 W when recharging the supercapacitor (a course of that takes 38 seconds).
Viking’s VT-PM persistent reminiscence drives are anticipated to be obtainable shortly at costs which can be as much as negotiations.
