Lantronix Spider KVM Overview. Amazingly scalable, Lantronix Spider KVM can be daisy-chained together. The Lantronix Spider-Series provides secure KVM access to servers over a standard IP network. It does not have the cable-length restrictions inherent with computer interface modules (CIMs) and current CAT5 KVM switches.
Absolutely brilliant at what it does. It's essentially an IPMI but not integrated with your motherboard. Supports KVM, WoL, SSH and Telnet (plus passthrough to the serial port).
