July 22, 2008 - Texas Memory Systems announced the RamSan-440, a new solid state disk (SSD) with high performance, capacity for a RAM-based system and a combination of features that help ensure the highest availability of data to its users.


The RamSan-440 is the first nonvolatile RAM-based SSD to sustain up to 600,000 input/outputs per second (IOPS) and deliver up to 512GB of storage capacity in a 4U rack-mount chassis, according to Texas Memory Systems. It also uses RAIDed NAND Flash memory modules for data backup and Texas Memory Systems’ patented IO² technology.


SSDs, like Texas Memory Systems’ RamSan-440, allow organizations to manage high transaction volumes and larger numbers of concurrent users with fewer servers, less power and without excessive application tuning. RamSan SSDs are used in the financial, telecom, e-commerce and online-gaming industries, as well as government, military and research organizations for online transaction processing, data warehousing and batch processing.


Typically, SSDs are deployed alongside traditional storage. For example, frequently accessed database tables and indexes may be stored on the RamSan, while less performance-sensitive database components remain on existing hard disk-based storage.


The RamSan-440 uses double-data-rate RAM to deliver 600,000 sustained random IOPS and over 4GB per second of sustained random read or write bandwidth, with latency of less than 15 microseconds. It is available in 256GB and 512GB configurations in a 4U chassis. The system can be SAN-attached or direct attached through up to eight 4Gb per second Fibre Channel ports. Multiple RamSan-440s can be combined to scale performance and capacity.
