The manufacturer promises a cost-effective solution that nearly achieves DRAM performance. He considers that the memory expansion is perfectly suited to applications in memory such as Redis, Memcached, Apache Spark and large databases.
Western Digital unveiled the new Ultrastar DC ME200 Series, which promises a cost-effective solution for extending server-based storage at speeds close to those of DRAM. ME stands for memory expansion and, as a storage extension, the drive is supposed to inspire real-time data processing, scaled databases, cloud services, and caching. applications. The manufacturer considers it perfectly suited to applications in memory such as Redis, Memcached, Apache Spark and large databases.
As an NVMe SSD, the Ultrastar drive complies with the PCIe standard of most countries. Intel-x86 servers. Available in 1, 2, and 4 TiB capacities, it does not require any changes to the operating system, system hardware, firmware, or applications, according to Western Digital. Form factors include a plug-in card (PCI-Express) and a 2.5-inch drive (U.2).
"By increasing storage capacity, the Ultrastar drive helps reduce the high costs of adding DRAM and eliminating the physical limitations of available DIMM slots when scaling is expensive or near impossible," says Ashish. Nadkarni. Citation, Vice President at IDC.
"The new Ultrastar drive is a natural addition to our portfolio of world-clbad data centers and addresses the growing demand from customers for accelerating business processes and real-time data processing across enterprise platforms." memory, "said Mark Grace, senior vice president of Western Digital. Business Unit Responsible Devices.
Chris Marsh, head of Western Digital, is working on a blog post with memory in memory "beyond physical DRAM." According to him, virtual memory provides fast DRAM performance through the use of more than 20 types of prediction, prefetching, and optimization algorithms. Ultrastar DC ME200 uses machine learning, pattern recognition, code reading, and other techniques to extract addresses en bloc, so that addresses are already waiting in the DRAM when the processor needs them later.
Marsh badures that there is no user-side modification to existing application stacks or extended support for Linux distributions. The new Ultrastar range is currently being tested by select customers, and Western Digital is offering it worldwide.
