  • Page 7: Chapter 1 - Introduction

    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.

  • Page 8: System Components

    You can monitor power supply temperature and voltages from the system monitoring software. If a RamSan-320/325 looses power, it operates for five minutes before shutting down. The shutdown process involves synchronizing data to the internal hard disk drives. If the system determines that the battery life will not last the full shutdown delay period, it starts the synchronization process.
