    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

    TMS equips the RamSan-320 with an internal backup RAID. The backup RAID can operate at about 80 MB/sec during operation. In order to operate the drives after a power failure occurs, the RamSan-320 RamSan-300/320 User’s Manual - 4 -...
