Within the lead as much as the Flash Reminiscence Summit subsequent week, many distributors have began asserting their new merchandise. At this time, Silicon Movement is unveiling their first enterprise-focused PCIe 5.0 NVMe SSD controllers set. These controllers discover themselves embedded in a versatile turnkey options platform encompassing completely different EDSFF requirements. A follow-up to the SM8266 launched in November 2020, the SM8366 and SM8308 belong to Silicon Movement’s 3rd Technology enterprise NVMe controller household.

Hyperscalers / cloud distributors require turnkey reference designs to rapidly consider the capabilities of recent controllers. In enterprise functions, the controller {hardware} is barely half the story. The related firmware / SDK, and user-programmability to allow buyer differentiation are additionally key facets. Holding this in thoughts, Silicon Movement can be placing give attention to the SM8366 reference design by giving it a separate moniker – MonTitan.
The MonTitan platform refers back to the turnkey design / firmware growth platform primarily based on the OCP Knowledge Middle NVMe SSD and NVMe 2.0 specs. Hyperscalers can readily deploy the MonTitan platform into their infrastructure for analysis, whereas datacenter SSD distributors can use it to make and market their very own datacenter and enterprise SSDs. The platform is at the moment out there in U.2, E1.S, and E3.S form-factors.
Silicon Movement claims that the platform’s ASIC and firmware mixture structure permits enabling of enterprise-level safety with out compromising on efficiency and QoS. In the direction of this, they’re touting two key options – PerformaShape and NANDCommand.
NVMe SSD controllers can current the SSD as a number of distinct storage volumes every with its personal I/O queue to the host system (namespaces). The PerformaShape algorithm can optimize the SSD efficiency in another way for every namespace utilizing per-namespace user-defined QoS settings. Silicon Movement claims true {hardware} isolation on this case to ship most bandwidth whereas guaranteeing that latency, QoS, and energy targets are met / obeyed. The NANDCommand function refers to Silicon Movement’s use of real-time machine studying together with the LDPC engine to assist with endurance (paritcularly vital for QLC).
The claimed efficiency numbers for the SM8366 controller can range for particular designs relying on the NAND expertise, variety of cube, and form-factor energy limitations. The corporate indicated that particular numbers for various form-factor reference designs will likely be introduced later. Sampling is slated to start in This autumn 2022.
Silicon Movement’s press launch exhibits the same old suspects offering supporting quotes – Micron, KIOXIA, and YMTC from amongst the NAND suppliers. Alibaba Cloud has additionally expressed curiosity in evaluating the platform, which bodes effectively for Silicon Movement’s enterprise SSD controller efforts.
