A high-availability flash storage appliance uses enterprise multi-level cell (eMLC) memory for applications requiring low power and low latency. The RamSan-820 from Texas Memory Systems offers a 24-TB capacity and occupies 1U of rack space. It also mitigates the effects of component faults and will continue to operate in the event of any single component failure. The device is based upon the latest release of the RamSan operating system.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
