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. This allows for: (1) Very large system memory: For in-memory processing such as in-memory databases. (2) Cost savings: Deployment of less DRAM and more NVM for CAPEX and OPEX savings, or deployment of larger memory for distributed in-memory data, and reduction in number of servers. (3) Transparent deployment and use: No modifications needed for OS or applications. (4) Easy upgrades: Plug more NVM into the system for additional memory.

vSMP MemoryONE is available from select hardware partners, packaged with certified NVM devicesTalk to our experts to see which MemoryONE solution fits your needs.


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.
