Micron introduces new PCIe enterprise SSD; aims for the datacenter

The U.S. semiconductor company's new I/O accelerator card intends to boost performance in enterprise servers, appliances and storage platforms.


This morning, Micron Technology introduced the P420m, a new PCIe I/O accelerator that it says will improve the overall performance of enterprise servers, appliances and storage platforms.

The Boise, Idaho-based company says the P420m is power efficient — it's all flash — and has extremely low latency. Micron's Ed Doller, who runs the company's Enterprise SSD group, calls it a "workhorse."

The new drive follows the P320h PCIe SSD, which was announced last year.

Typical use cases for the accelerator include online transaction processing (the "OLTP" mentioned above), data warehousing, and virtualization. In a MySQL server running an OLTP benchmark, the card delivered more than 3,200 web server requests per second, the company says. (It also says things like, "P420m ends the wait game for digital data," but let's not get ahead of ourselves, shall we?)

From a hardware standpoint, the P420m uses Micron's custom ASIC controller, 25-nanometer multilevel cell NAND flash, DRAM, firmware, and drivers. It employs the company's "Extended Performance and Enhanced Reliability Technology" architecture (or XPERT for short, which is about as adorable as the enterprise gets, I think).

The card comes in a half-height, half-length format for rack-mounted servers as well as a 2.5-inch format. Capacities include 350GB, 700GB and 1.4TB; the 1.4TB version is only available in the HHHL format.

Production will begin in June 2013.
