Micron Technology on Thursday announced a new PCIe all-flash I/O accelerator to improve performance in enterprise servers, appliances and storage platforms. The new Micron P420m solid-state drive combines consistent performance, inherent power efficiency of an all-flash system with advanced reliability. The P420m speeds up demanding data center applications, including online transaction processing (OLTP), data warehousing and virtualization.

"The P420m is a true workhorse – it delivers where performance matters most. Introduction of the P420m is a testament to our commitment to storage innovation for all levels of integration. We've expanded our portfolio to address the changing storage needs of today's data centers, regardless the workload," said Ed Doller, vice president and general manager of Micron's enterprise SSD division.


The P420m is a "cache master". It provides faster throughput and serves up high-demand data in a flash. Micron P420m is designed using Micron's custom-designed ASIC controller, advanced 25nm- multilevel cell (MLC) NAND flash memory, DRAM, firmware and drivers to create a truly vertically integrated solution, which ensures the ultimate level of storage quality and efficiency. The P420m uses Micron's XPERT [extended performance and enhanced reliability technology] architecture, which closely incorporates the storage and controller through highly optimized firmware algorithms and hardware enhancements. The end result is a set of market-focused enterprise features that deliver ultra-low latencies (75ns read latency, 15ns write latency), improved data transfer time (up to 1.8GB/s or 3.0GB/s, depending on the version), power-loss protection and cost-effectiveness, along with higher capacities and power efficiency.

The P420m low-profile accelerator card comes in a half-height, half-length (HHHL) form-factor for rackmount servers. It is also the industry's first MLC PCIe solution available in a 2.5” form-factor. The latter is growing in popularity among IT administrators because of its ease of serviceability and scalability; it allows drive access from the front of the server, which eliminates the need to power down the server for drive service. This hot-swap capability dramatically decreases server downtime and maintenance costs.

When tested against competing PCIe solutions in a MySQL server running an OLTP benchmark, the P420m is the fastest and most consistent performer, delivering more than 3200 web server requests per second, according to Micron. It handily manages online requests during peak traffic times, improving the overall end-user experience.

The drive will be available in 350GB, 700GB and 1.4TB capacities. Micron is currently sampling the P420m with production expected to begin in June 2013.
