Chapter 1 – Introduction 1.1 Overview The RamSan-3xx series solid-state disk uses SDRAM (memory) as its primary storage. This technology enables practically instantaneous data access, which results in dramatic application performance increases. Texas Memory Systems (TMS) designed the RamSan to be highly available and fault tolerant. The system has higher availability than RAID or JBOD systems because the primary storage media is SDRAM, which does not require moving parts. Add
