Diablo storage tech makes it into Lenovo X6 servers

Diablo Technologies is integrating its Memory Channel Storage (MCS) technology into the latest Lenovo X6 servers to power eXFlash microcontrollers. News follows Diablo's announcement that it has resolved its legal issues with Netlist.

Litigation had been ongoing since December 13, 2013; Netlist accused Diablo of stealing its flagship proprietary technology, HyperCloud, for Diablo's ULLtraDIMM product. Diablo filed a lawsuit against Netlist a year later for violating Diablo's Intellectual Property rights, which led to a preliminary injunction against the company for controller chips used by SanDisk in its high-speed ULLtraDIMM SSD product line.

This meant Diablo was banned from manufacturing, using, distributing or selling the high-speed memory chips.

In late April, Diablo announced in a press release "the United States District Court for the Northern District of California ruled to completely dissolve a preliminary injunction enacted in January 2015. The ruling definitively reaffirms Diablo's right to ship its award-winning Memory Channel Storage (MCS) chipset without restriction." The rule comes after Diablo won "decisive victory" in late March, where a federal Jury ruled unanimously in favour of the company.

Lenovo eXFlash

Lenovo's eXFlash DIMMs are available in 200GB and 400GB with power fail protection feature.

Lenovo's new X6 rack and blade servers support up to 32 eXFlash DIMMs per system, which translates into 12.8TBs of high-performance system storage and designed for accelerating a wide range of enterprise workloads, including databases, analytics and virtualisation. Lenovo acquired the X6 server product line from IBM last year.

In November 2013, just before litigation began, Diablo struck two significant strategic alliances for its MCS architecture. 60East Technologies announced it would be incorporating it into its Advanced Message Processing System (AMPS) messaging platform, while a collaboration with SanDisk has MCU being integrating with SanDisk's ULLtraDIMM (ULL) technology for servers.

The MCS architecture connects NAND flash directly to the CPU through a server's memory bus; persistent memory is essentially attached to the host processors of a server or storage array. This configuration allows for linear scalability in performance at extremely low latencies for high-demand enterprise applications, the company said in November 2013.
