In addition to the standard densities of 8GB, 16GB and 32GB, which are sampling in high volume to several customers, Micron Technology has introduced a 64GB LRDIMM to meet the ever-growing density requirements of servers.
The loading profile of previous registered DIMMs (RDIMMs) was constrained in the amount of available memory for virtual computing environments, Micron indicated. LRDIMMs reduce the load on the server memory bus and enable higher data frequencies and memory capacity.
"LRDIMM technology will change how DRAM is utilized in servers by enabling datacenters to support significantly more memory-intensive applications with the same number of CPUs," said Robert Feurle, VP of DRAM Marketing for Micron's DRAM Solutions Group.
LRDIMMs, coupled with appropriate server virtualization strategies, will maximize infrastructure and optimizes return on investment, Micron said. For example, utilizing Inphi's Isolation Memory Buffer (iMB) chip in place of a register, Micron's LRDIMMs reduce current DDR3 server module loads 2X for a dual-rank module and 4X for a quad-rank module.
As new platforms are developed to expand scalability and virtualization of server networks, applications will rely increasingly on the competitive edge provided by Micron's LRDIMM portfolio, the company noted. Supermicro SuperServer solutions are one of the first platforms to support Micron's LRDIMM product line, it added.
Samples of Micron's new LRDIMMs are available in 8GB, 16GB, and 32GB capacities, with 64GB modules expected to be available in February 2012.
