Radian Memory Systems releases "OC2 on U.2": RMS-350 Cooperative Flash Management SSDCALABASAS, Calif., July 26, 2018 /PRNewswire/ -- Radian Memory Systems®, Inc. releases the industry's first Open-Channel 2* compliant Flash SSD in a U.2 form factor with up to 12TB of Flash, and uniquely includes up to 12GB of byte addressable, PMR style User NV-RAM. Targeting All-Flash Arrays, hyperconverged systems, and cloud storage, the RMS-350 SSD offers highly parallelized, deterministic I/O while minimizing tail latencies for data center workloads. This includes support for Cooperative Flash Management (CFM) based on Radian's Symphonic™ CFM technology or Radian's implementation of the new Open-Channel 2 interface. Variations of software-defined, Open-Channel SSDs are gaining traction throughout hyperscale. With early versions deployed by Baidu and Alibaba in China, other variations, such as a future proposal by Microsoft® Azure® for their "Project Denali," are anticipated to be available within the next year. Founded in 2010, Radian has pioneered what is known as Cooperative Flash Management (CFM) technology. "With the RMS-350, we're leveraging some of our innovative Cooperative Flash Management functionality to bring data center functionality into an SSD with an Open-Channel 2 compliant interface," said Radian's CEO, Mike Jadon. While this Radian functionality has been available in the company's Symphonic SSDs for several years, the RMS-350 represents the first SSD to include it and numerous other features in an SSD with an Open-Channel 2 compliant interface: Software/Firmware 'Idealized Flash'
ASL Configurator
Cooperative and 'Decoupled' Wear Leveling
Cooperative and 'Decoupled' NAND Maintenance
Radian publicly released Symphonic, the first implementation of a CFM architecture, in 2015. Symphonic redistributes Flash management responsibilities between the host system interface and SSD. This redistribution is based upon space management, data placement, cleaning, and scheduling residing in the host, with media management residing in the device, and these processes being performed under cooperative host control. As the winner of the Most Innovative Technology award at the 2015 Flash Memory Summit conference, Symphonic: "…enables the host to control and schedule processes such as garbage collection, …The firmware also transparently handles and abstracts various NAND properties …Enables readily optimizing opposing performance and efficiency constraints unique to Flash memory …Preserves host data layout optimizations through to physical media" ** The RMS-350 utilizes this Radian technology, including the 'Idealized Flash', ASL Configurator, Cooperative and 'Decoupled' Wear Leveling, Cooperative and 'Decoupled' NAND Maintenance and other Radian features to deliver an SSD with data center functionality that retains software-defined, host data layout and deterministic host scheduling with an Open-Channel 2 compliant interface. Also in 2015, the company released the RMS-250 which was the industry's first CFM Flash SSD and the first Flash SSD to include a type of user accessible Persistent Memory Region (PMR). This byte addressable, non-volatile user accessible NV-RAM could be memory mapped, or block addressable via standard NVMe™ commands, with unique functionality enabling hosts to control zero-copy transfers of data between the Flash and NV-RAM memory medias. Now in 2018, the RMS-350 builds upon this same innovative architecture with high density eTLC Flash and support for Symphonic CFM and Radian's Open-Channel 2 implementation. Hardware The 4GB or 12GB of PMR style User NV-RAM provides functionality similar to an on-board NV-DIMM-N, but unlike a NV-DIMM, scales with Flash capacity as drives are added to a system, and does so without cabling to remote capacitor packs. This NV-RAM appears as an independent NVMe block device that can be accessed via NVMe, or memory mapped (mmap) as byte accessible (dword) memory for Programmed I/O (PIO). The RMS-350 includes high availability features such as dual port, hot plug/surprise remove, fault tolerant memory management, and comprehensive diagnostic lifecycle capabilities to meet data center and enterprise OEM requirements. RMS-350 evaluation units are available now to select customers and general availability is scheduled for fall 2018. Radian Memory Systems will be exhibiting at the Flash Memory Summit, August 7, 2018.
