ULLtraDIMM revolutionizes data storage by placing flash on the memory bus

The SanDisk ULLtraDIMM DDR3 SSD brings latency as low as five microseconds by sidestepping the traditional storage stack, and communicating via the DDR3 bus

The hardware consists of a JEDEC-compliant ULLtraDIMM that presents itself as a block storage device with 200 or 400GB of capacity. The ULLtraDIMM utilizes two Marvell 88SS9187 controllers running the Guardian Technology Platform to increase endurance and reliability. This tandem delivers random read/write performance of 140,000/40,000 IOPS, and sequential read/write speeds up to 880/600 MB/s. Ten DWPD (Drive Writes Per Day) of endurance, and a five-year warranty (or TBW) are provided by SanDisk 19nm eMLC NAND. The ULLtraDIMM also sports a 2.5 million hour MTBF, and host power-loss protection. The most important attribute is latency as low as five microseconds. This even undercuts new NVMe PCIe SSDs, which hover around 20 microseconds.

The ideal configuration for an ULLtraDIMM deployment is four to eight DIMMs at a minimum, but the platform scales up to 32 DIMMS and 12.8 TB of storage.
