vSMP MemoryONE

Software-defined memory: Use cost-effective non-volatile storage-class memory (SCM) and other high-performance storage devices to transparently replace expensive server DRAM and expand beyond their capacity limits.

vSMP MemoryONE pools DRAM and NVM memory capacity into a single memory space for use in industry-standard, x86 servers. Organizations that run workloads with medium- to high-memory requirements can meet these workload requirements using an economically efficient combination of memory technologies, while benefiting from DRAM-like performance.

vSMP MemoryONE uses non-volatile memory to expand or replace DRAM.


vSMP MemoryONE enables both DRAM replacement and DRAM expansion by turning NVM into a memory. vSMP MemoryONE offers users cost-effective memory and the option to scale beyond the limits of industry-standard, x86 servers.

MemoryONE reduces the overall number of servers for distributed in-memory applications, as each server node carries much higher memory capacity.

DRAM Replacement
Workloads that can fit into a standard, commercial, off-the-shelf (COTS) server system using high-end memory configuration can now be executed with much lower DRAM capacity installed. For example, instead of installing 768GB of DRAM into a dual-socket standard server, an organization could install 128GB of DRAM and approximately 700GB of high-performing NVM, saving on both CAPEX and OPEX.

DRAM Expansion
Workloads that need more memory than a standard server system no longer require high-end systems. For example, a standard dual-socket server could now easily reach 24TB system memory. And, previously unimaginable opportunities for leveraging in-memory computing are now a reality: Organizations can finally cost-effectively put a 40TB database into system memory and reap the benefits of faster transaction (OLTP) and analytics (OLAP) processing.
