The IMG4216-25 gateway enables network and system administrators to manage the entire IT infrastructure in their distributed businesses and branch offices at a fraction of the cost and complexity of other solutions.
Opengear's next generation Integrated Management Gateway family provides the first truly integrated management solution. The IMG4216-25 provides:
- Management LAN with 24 Ethernet ports for direct connection to service processors and network consoles
- Single integrated gateway that manages the full spectrum of serial and network connected servers and appliances at the site
- Service processor and BMC management for IPMI, RSA, DRAC, iLO, ALOM and more
- Centralized in-band and out-of-band management gateway with encrypted authenticated access for local and remote management
- Sophisticated monitoring, alerts and alarm management with embedded Nagios
Integrated management LAN
Branch offices in distributed enterprises host a diversity of advanced IP networks, applications and computer configurations. A dispersed array of system and network administrators, applications specialists and vendor help desks, and other service providers then seek access to their piece of this infrastructure - each looking to make their own safe access holes in the remote site's security fabric.
The IMG4216-25 gateway provides a single integrated point of secure access for all these managers and for all their tools, protocols and management applications. The gateway has flexible yet powerful access control policies, restricting access by IP address, password and account. Users are locally or remotely authenticated and then restricted to only using nominated services and TCP/UDP ports to access the specifically approved devices. And all communications are encrypted.
The gateway's Ethernet ports provide a direct management LAN connection to 24 network management consoles. The IMG4216-25 gateway also provides direct access to 16 serial management consoles. However these numbers can be extended by connecting additional CM4000 console servers and external Ethernet switches to the IMG management network.
In-band and Out-of-band management
Remote branches and SMB offices are managed on a day to day basis using in-band protocols and applications over the main production network. In-band applications such as WebEx, GoToMyPC, Nagios and OpenView, and tools like Telnet, Remote Desktop and VNC enable the applications, the computers and the network devices to be configured and controlled remotely. However these computer and network devices also have out-of-band access facilities so they can still be accessed, reconfigured and recovered in event of failure of the normal in-band management methods or connections (e.g. when the operating system crashes or a network connection fails).
The IMG4216-25 gateway provides both in-band and out-of-band access for all these management facilities. The gateway can be accessed in-band securely by the local or remote manager using the public data network or a private IP network. Alternately it can be accessed out-of-band using an alternate broadband route or a dial-in modem. Therefore if the in-band production network is down, access is still available out-of-band. Additionally the gateway's SSH tunneling and robust authentication enables the manager to securely use classical in-band applications over these out-of-band channels to reconfigure operating systems and reset network etc.
Service processor management
The IMG4216-25 service processor manager simplifies out-of-band management of servers with service processor technologies by automating user access and consolidating IP connections. The gateway's multiple Ethernet ports connect point-to-point with IPMI (1.5 and 2.0), DRAC, RSA, iLO and ALOM service processors.
The gateway's SDTConnector management client integrates with Dell OpenManage, IBM Director and other lights-out management applications to simplify operations. The service processors use secure SOL and console communications over side-band or out-of-band channels to remotely control the servers at all levels - from bootp right up to the application layers. The BIOS can be reconfigured, the operating system rebooted or the server power cycled - even when the main CPU itself is not operating. Using these same out-of-band channels, managers can have full KVM graphical control of applications running on the server, even when the in-band network access to the server is down. And the IMG4216-25 makes this remote control easy.
Proactive monitoring and alerts
The IMG4216-25 gateway monitors and logs all in-band and out-of-band access and management activity. The IMG gateway integrates into the popular Nagios-based monitoring infrastructure by embedding the Nagios NSCA client and NRPE server. Acting as distributed monitoring servers, the IMG gateway runs checks in conjunction with a master Nagios server.
In the event of distress at a remote site the IMG4216-25 will deliver alerts that identify the problem; then provide a secure tunneled connection to the server, device or application in need of help; and enable the tools the administrator will need to fix the problem. This proactive monitoring and maintenance ensures faster troubleshooting and problem resolution and reduced operational costs. Also the advanced auditing and tracking helps the organization conform to mandatory compliance requirements such as Sarbanes-Oxley, GLBA and HIPAA.
High Availability
The IMG4216-25 was designed to deliver reliable 24/7 remote management access at central sites and remote branches. Each unit ships with dual input dual AC power supplies with automatic failover so the gateway can be fed from independent AC power sources. The IMG4216-25 also supports Ethernet failover and automatic dial-out connection in the event the primary network connection fails.
