|
|
| |
KVM switches enable you to access and control a computer by connecting directly to the Keyboard, Video and Mouse (KVM) ports. KVM technology needs no target server modifications or software. It means the target computer is available at all times, from BIOS to Windows. KVM provides true motherboard level access and supports multi-platform servers and serial devices. |
|
|
| |
From the original concept, KVM technology has now evolved into being an enterprise IT infrastructure management system. From a single interface, you have direct access to servers and devices in multiple remote locations. KVM over IP solutions now also include full multi-location failover, a direct interface into the new server management standard (IPMI), and the ability to map local storage media to a remote location. |

KVM technology |
|
|
| |
KVM switching connects directly to the keyboard, video and mouse signals on any computer. It provides easy plug and play installation operating completely independent of software and network operating systems, and provides real-time access between a user and multiple computers. KVM is optimized for environments where users and systems reside in the same location and is ideal for accessing centralized multi-PC and multi-rack environments. |

KVM over IP |
|
|
| |
KVM over IP digitizes the keyboard, video and mouse data and uses IP technology to move the KVM data. KVM over IP connects directly to KVM signals on any computer and is non-invasive to the computer, no added software/hardware. The technology leverages the existing network infrastructure and supports both local and remote users. KVM over IP works in heterogeneous hardware environments and is ideal for managing multi-location data centers and branch offices. By allowing one or more users to access and control multiple servers. |

KVM switches enable businesses of all sizes to realize the following benefits: |
|
|
| |
Reduce costs - a KVM switch eliminates the need for connecting a keyboard, video monitor and mouse to each server, so a business only needs one or very few keyboards, video and mouse devices to control and manage many servers. This not only lowers hardware costs, but also frees up valuable physical space, along with reducing demands on electrical power and heating and cooling systems. |
|
|
| |
Improved business continuity - KVM switches allow "out of band" access to a company's servers and other IT devices. As such, they are not dependent on a corporate backbone or network. Thus they allow IT personnel to access, control and manage the company's servers even if the corporate network itself is down. A KVM switch can even enable a complete system reboot from a remote location. |
|
|
| |
Hardware platform and OS independence - KVM switches work in heterogeneous server environments. They are not dependent on the hardware or operating system from a specific manufacturer. As such, they can function in corporate IT environments that have servers from different manufacturers like HP, IBM, and Sun , that run on different operating systems like Solaris, Unix, or Windows. |
|
|
| |
Digital and analog KVM switches are available for data centers of every size. An "out-of-band", analog KVM solution is generally best suited for small to mid-sized data centers. Whereas an "in-band", digital KVM solution is best for supporting large, national or globally distributed data centers. |
|
|
| |
In addition to KVM switches, connectivity products can extend access to servers and other devices, whether across the room, the building, or a campus. |
