PCIe NVRAM card improves response time in servers, storage appliances


Chatsworth, Calif.—VMETRO announced the latest member of the Umem NVRAM product line, the MM-5453CN, which is a low-profile, half-length PCI card with a PCI Express x4 interface for use by OEMs in enterprise-class server and storage appliances.

The MM-5453CN is targeted at Tier I/II OEM customers with NAS, SAN management, virtualization, disk-based backup and continuous data protection applications.

The application optimized Umem DMA engine and memory controller provide low latency accesses for operations involving file system journaling, logging and write caching. Unlike other forms of persistent (non-volatile) storage, Umem NVRAM cards are only limited by the throughput and access times of the peripheral interface, not the storage media.

The MM-5453CN was developed for the latest PCI Express based appliance platforms. PCI Express fabrics enable concurrent host access of multiple peripherals, and as a serial interconnect, signal integrity is improved over higher clock frequencies when compared to more traditional parallel buses such as PCI-X. Storage capacities for the MM-5453CN range from 512-Mbytes, to 1-Gbyte, and 2-Gbytes of DDR memory with ECC.

Up to three re-chargeable lithium-ion batteries are located on a mezzanine that when fully configured has been designed to stay within the PCI single card slot envelope. The MM-5453CN's compact form factor is compliant with the PCI-SIG specification for low profile, mid-length options and ideal for use in tightly integrated appliances.
