Sentinel

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.

Integrated power control and quick “out of the box” setup and deployment

Remote power management is made possible through simple integration with Thinklogical’s PDU 4/4. This gives user the ability to power cycle, power on/off remote equipment, and control power to individual servers. For the non-Linux user, a common browser based GUI interface that is simple to set up and use provides easy, secure administration and management of IT equipment.

Resembles a true Linux network server

Modular in design, the core of the Sentinel is an x86-based computer running GNU/Linux. In addition, the Sentinel has built in technologies such as 512 MB compact flash drive (which is large enough to hold any 3rd party software components) and support for plug-compatible micro drives. Upon setup the Sentinel generates a unique set of host keys, a crucial security feature which some traditional console servers lack. Another exceptional feature of Thinklogical’s console server line is full distribution, non-embedded Linux. The Sentinel is the only console server on the market that is able to integrate into any system and configuration management software programs that are being utilized by your enterprise. This enables users to customize the capacity of the Sentinel, as well as its level of integration into their particular environment. In addition, users are able to match security technology to fit their processes while modifying and enhancing features to meet their specifications

Enhanced security framework

Data management information is protected through the Sentinel’s standard encryption tools such as Secure Shell (SSH) and Secure Socket Layer (SSL). Access by authorized users is assured via authentication schemes such as RADIUS, TACACS+, LDAP, Kerberos, NIS and RSA Security’s SecurID tokens. The Sentinel also supports network port bonding for added protection. Using a 256K FIFO audit trial per device port, diagnostics can easily be performed should an attached device fail; this allows for faster problem resolution and maximizes network uptime. Advanced features such as simple integration with Thinklogical’s PDU, which addresses remote access of power management, meet the requirements of the most demanding system and network applications.

Available in 8-, 16-, 24-, 32- port models that fit in 1U rack space, the Sentinel provides the layer of security, management, and control over widespread infrastructures that users require.
