New product class

Remote server management through Internet connections is fraught with difficulties: complicated safety configurations, slow data throughput that lock up system resources, and poor image quality and mouse behaviour all contributed to an unsatisfactory situation. Thanks to AdderLink IP, all this now has an end:

Security, speed and convenience

Secure VNC – a completely new security architecture – was first implemented first in AdderLink IP. The key feature of this unit is the fast and easy adaptability of its security configurations and features (such as AES 128-bit encryption and RSA 2048-bit public key authentication) to individual security requirements. An equally pleasant surprise is the ease of performing routine work with AdderLink IP, to which its fast data exchange, fast mouse response and outstanding image quality contribute.

• Simple installation and setup, also of security settings
• Convenient, uncomplicated operation on the client side
• High transfer rates of remote screen image and a near real-time feeling of the mouse pointer
• High screen resolution and colour depth

Highlights

• Access through LAN/WAN or directly through modem or ISDN
• Access to and management of an almost unlimited number of servers through connected KVM switches
• Maximum security: built-in authentication through 2048-bit RSA keys; built-in data encryption through 128-bit AES, and more
• No server software needed; operating system independent
• Automatic video compression adaptation to available bandwidth
• One to four simultaneous remote users; automatic bandwidth adaptation (e.g. 100 Mbit Ethernet and modem connection)
• Port for local KVM station
• Operation through browser or VNC viewer
• Easy installation and operation
• Up to 16 separate user profiles
• Detailed event logging

Access through LAN/WAN or direct dial-in

Normally, AdderLink IP is operated through Ethernet. If the network is down, the servers can still be reached through an analog or ISDN modem connection, which can also be used for accessing the servers from home or on the road.

Simple initial installation and setup

Ease of installation has a high priority: An administrator should be able to unpack, get to know and fully set up the device within 20 minutes. This applies especially to security: To optimize security settings for a particular environment, operation needs to be clear and simple. An on-screen menu on the local operator station provides the interface for initial setup.

Easy to use

After a user login, the viewer window appears on screen, showing the monitor image of the default PC with access to all menus required for the session. Users can, for example, select another server from a pull-down menu and switch off its power supply to reboot it. For the first time, the server screen and all controls required within a session are presented in a single window.
Here you can arrange an online demonstration. Please give a suitable date and time as well as your phone number.

Four simultaneous users

Up to four remote users can access a server at the same time, for example to discuss or remedy a problem together. For exclusive access, users can also activate Private Mode. The image quality and refresh speed is adapted individually to each user’s available bandwidth.

Viewer selection

Each remote administrator can choose between a Java-capable browser or a VNC viewer. It is even possible for several users to access AdderLink IP from different platforms at the same time. The VNC viewer is faster and provides a higher level of security and a better image quality. It can be downloaded from AdderLink with a standard browser and is executable without installation.

VNC

VNC (Virtual Network Computing) is a de-facto standard used throughout the world and which used to be in the public domain. VNC is truly platform-independent, compact, fast, and easy to install. Until recently, it still had security gaps and required software to be installed on the server.

VNC was devised in 1998 by AT&T Cambridge, where it is still being further developed. In 2002, the development team founded its own company, RealVNC Inc. and developed a completely revised, unique security architecture – Secure VNC – for this type of application. Adder developed AdderLink IP in close cooperation with RealVNC. For the first time, the server-side Secure VNC has now been incorporated in a specially optimized KVM product. Read more ...

Benefits

Conventional VNC solutions require a program to be installed on the servers. This uses up processor capacity (especially if a high level of security is required) and means that remote server access after a restart is possible only once this software has loaded. BIOS level support, providing access as soon as the server is switched on – for example to change the BIOS settings – is not possible. With AdderLink IP, the software runs in AdderLink, not on the server. This reduces server load and – thanks to a dedicated RISC processor – boosts operating speeds. No special software is needed on the servers, making the system highly flexible and platform-independent.

Security

AdderLink has an unparalleled security architecture – see the Whitepaper (English). AdderLink features Secure VNC – a fully revised VNC security concept. But even a maximum security system does not provide the required security levels if complicated operation causes the user to choose inappropriate settings. With this in mind, AdderLink IP features an exceptionally simple, clear security settings configuration interface.

Flexible expansion

AdderLink can be used with all popular makes of KVM switches. Its configuration is especially convenient in combination with Adder switches, although operation is the same with all switches.

The number of users with simultaneous access to different servers can be increased by simply adding further AdderLink IP units. Because of the local console port – which can also be used for KVM switches – no local ports are lost.

Remote server restart

Normally, servers are restarted through their operating system. If a server no longer responds to command inputs, AdderLink IP can switch the server’s power supply off and on again through its serial remote power switching port. With the ePowerSwitch M/S, which is used for this purpose as standard, up to 40 servers can be switched directly from the AdderLink IP’s user interface. Other serial-port devices can also be used.
