1.2System Components
The system components for the RamSan-300 include:
•Main system memory ranging from 16 to 64 Gigabytes
•One to four Fibre Channel controllers
•Dual, redundant hot-swappable power supplies
•Redundant fans
•Ethernet monitoring port
•Serial monitoring port
•Front panel display for monitoring and configuration
•SNMP based monitoring
•Java-based Web monitoring
The system components for the RamSan-320 also include:
•Internal backup RAID
•Redundant batteries (N+1)
1.3Power
The RamSan includes two power supplies. Only one power supply is needed to run the system. The power supplies are auto-ranging (they accept either 110 or 220 power).
The RamSan-320’s power supplies are connected to an internal battery pack. The battery pack provides up to 30 minutes of operation after a power failure. In the event one battery or power supply fails, the other functional power supply and battery combination handles the system operation. You can monitor power supply temperature and voltages from the system monitoring software.
If a RamSan-320 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.
When power is restored, the RamSan-320 restores system memory with the data from the internal hard disk drives and then resumes normal operations. In addition, the system begins recharging the batteries. You can monitor the battery charge levels using the bundled remote monitoring software.
1.4Non-Volatility
By utilizing internal hard drives and batteries, the RamSan-320 combines the performance of SDRAM storage with the non-volatile nature of hard disk drives. 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
