Sentinel offers high availability – 24 /7/ 365 – with advanced failover architecture


Hot-swappable power supplies, serial device modules, NICs and field replaceable CPU boards


For distributed “mission critical” networks and IT infrastructures, Thinklogical’s Sentinel series of secure console servers provide users with secure access and control of network devices and servers. Advanced failover architecture integrates additional functionality into the Sentinel series of console servers. Redundant, hot-swappable power supplies allow for uninterruptible power, enabling users to remove a failed power supply while the unit is running. In addition, hot-swappable access modules, NICs and field replaceable CPU boards makes the Sentinel fail-safe, ensuring high availability, while increasing the time and effectiveness of systems administration and IT staff.
