SSD E2 is a new solid storage format in which they work key industry actors such as Micron, Meta, Microsoft, Sandisk and Pure Storage through the Storage Networking Industry Association and Open Compute Project organizations. Your goal is balance the capacity, efficacy, performance and costs of professional storage for servers and data centers.
The traditional division between hard discs and business solid state units do not satisfy all use cases, explain the promoters of SSD E2, a new format that with capacity potential of even even 1 PBYTE OF MEMORY FLASH QLC per unitthey could become the intermediate option that the industry needs.
SSD E2 focus on data called “hot”the information to which it is accessed with sufficient frequency to overload hard drives, but that does not justify the high cost of flash memories used in higher performance business SSDs. The new AI applications, the analysis channels and emerging digital services are raising the temperature of the data, previously considered cold. The result is a growing midpoint that these units intends to address.
Designed from scratch, the SSD E2 measure 200 mm X 76 mm x 9.5 mm and have a thickness of only 9.5 mm (0.4 inches). They use the same edsff connector as the E1 and E3 units, but they are Optimized for dense and high capacity implementations. A standard 2U server could house up to 40 E2 units, which translates into 40 bp of flash memory in a single chassis.
The units would be connected by the PCIE 6.0 interface through four lanes and could consume up to 80W per unit, although the majority is expected to consume much less, in the range of 20 and 30 watts. The performance would be below traditional SSDs, but with maximum transfers of up to 10,000 Mbytes per second it would be much higher than that offered by hard drives.
Pure Storage presented in May a prototype of SSD E2 of 300 Terabytes. It has a large flash controller, six -piece dram caches and numerous capacitors for a safe vacant buffer in case of unexpected energy cut. The adoption of the SSD E2 standard would allow a company like Pure reduce costs and, at the same time, take advantage of solid state units.
The SSD E2 format represents a Practical solution, flash basedto the growing need for high capacity “hot” storage. It will not replace hard drives overnight, but the combination of Petabytes capacity, sufficient performance and a compact implementation in 2U makes it one of the most attractive recent developments in business storage.
That said, server platforms They are not yet ready to support E2. The challenges of thermal, energetic and physical integration will take time to resolve, and suppliers are expected to launch new chassis designs optimized not only for the E2 format, but also for other formats for ‘hot’ -based data ?? in flash.
