The RamSan-440 is a new solid state disk with record high performance, record high 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 worlds first non-volatile RAM-based SSD to sustain 600,000 IOPS (input/outputs per second) and deliver 512GB of storage capacity in a 4U rack-mount chassis. Its also the first SSD to use RAIDed NAND Flash storage modules for data backup, and the first system to incorporate Texas Memory Systems patented IO2 (Instant-On Input-Output) technology.
Solid state disks, like Texas Memory Systems RamSan-440, allow organizations to manage very high transaction volumes and larger numbers of concurrent users with fewer servers, less power, and without excessive application tuning, thus increasing performance while lowering cost and administration efforts. RamSan solid state disks 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, solid state disks 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. However, the growing size of mission-critical databases and the falling cost of solid state disks have increased demand for high-performance, high-capacity SSDs. The RamSan-440 meets this demand without sacrificing reliability or value.
The RamSan-440 uses DDR2 (double-data-rate) RAM to deliver 600,000 sustained random IOPS and over 4GB/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 eight 4Gb/second Fibre Channel ports. Multiple RamSan-440s can be combined to scale performance and capacity.
The RamSan-440 uses RAID protected Flash memory modules to rapidly back up the RAM-based data and ensure non-volatility for the system. In Active Backup mode, the RamSan-440 continuously backs up data to the internal redundant Flash modules without impacting system performance. The RamSan-440 can back up or restore the entire 512GB of data in just six minutes. Texas Memory Systems patented IO2 technology further improves system availability by making user or application-requested data instantly accessible after the system is powered on.
