Chapter 1 – Introduction 1.1 Overview The RamSan-3xx series solid-state di sk uses SDRAM (memory) as i ts primary storage. This techn ology en ables practically instantaneous data access, which results in dramatic application performance increases. Texas Memory Systems (TMS) des igned the RamSan to b e highly availabl e and fault tolerant.
1.2 System Components The system components fo r the RamSan-300 i nclude: • Main system memory ranging from 16 to 64 Gigabytes (300/320) • Main system memory ranging from 32 to 128 Gigabytes (325).
failure occurs, the RamSan-320/325 co ntains redundant b atteries. When fully functional and fully charged, the batteries are able to provide at least 30 minutes of operation. The system monitors the internal disks and batteries for a failure condition.
1.6 Performance The RamSan-3xx series solid st at e disk is the ultimate in performan ce storage. With up to ei ght Fibre Channel ports in a 3U package, the RamSan-3xx series delivers unpara lleled bandwidth a nd I/O. The RamSan-3xx series is capable of 250,000 IOPS (I/O operations per second) and 1,500 MB /sec of read or write performance.
Chapter 2 – Installation 2.1 Electro-Static Discharge Warning Important: Please take full E . S.D. precautions if it is n ecessary at any time to come into contact with any circuit boar ds , components or conne ctors. Electrostatic discharge can damage the components used in t he RamSan and its interfaces.
