  • Page 7: Chapter 1 - Introduction

    Additionally, SDRAM has a very high mean time between failures (as high as several hundred years) according to some studies. The RamSan-120’s internal disk drive and battery provide a fully non-volatile solution. The RamSan complements existing disk drives, JBOD, or RAID, in performance sensitive applications.

  • Page 8: Non-Volatility

    The RamSan-120 is the first and only solid state disk to implement ECC- protected DIMMS as a RAID (redundant array of independent DIMMs). Similar to disk-based RAID, if an entire DIMM inside the unit fails, other DIMMs will rebuild that information without interruption.

  • Page 9: Configurable Backup

    1.6 Performance The RamSan-120 series solid state disk is the ultimate in performance storage. With two Fibre Channel ports in a 1U package, the RamSan-120 delivers powerful bandwidth and I/O. The RamSan-120 series is capable of 70,000 IOPS (I/O operations per second) and 400 MB/sec of read or write performance.

  • Page 10: Chapter 2 - Installation

    2.2 Battery Warning The internal battery in the RamSan-120 is charged with enough voltage to power a fully loaded system for approximately seven minutes. However, the battery may not be fully charged when you install your system.

  • Page 11: Connecting The Power Supply

    Install the socket outlet in an easily accessible location near the equipment. For normal system operation, connect the power supply to an external power source. If a RamSan-120 completely looses external power, it will shutdown after a defined amount of time. AC Voltage “Power”...

    The SNMP standards provide a framework for the definition of management information along with a protocol for the exchange of that information. The RamSan-120 Series is compatible with SNMP V2c. The SNMP model contains “managers” and “agents.” A manager is a software module responsible for managing the configuration on behalf of the network management application end users.
  • Page 20 Managers can access statistical information from the RamSan through its management information base (MIB). In addition, the RamSan can issue up to thirteen traps. For more information about configuring SNMP settings, see Chapter 8 – SNMP Configuration. RamSan-120 User’s Manual - 16 -...
