High Density vs Distributed KVM : Lantronix's solution

Lantronix SecureLinx Spider provides secure KVM (keyboard, video, mouse) management of servers over an IP network. Unlike traditional KVM switches, Spider offers a flexible, scalable and affordable CAT5-based remote access KVM solution in a cable-friendly, compact “zero-footprint” package.

The latest addition to the SecureLinx family of Device Management and Control solutions, this KVM over IP solution eliminates server-to-switch CAT5 cable distance limitations, and gives system administrators non-intrusive and cost-effective 24/7 access to servers across a wide variety of IT/network environments: mission critical servers in high-density data centres, servers distributed over corporate campuses, multi-floor buildings, remote/branch office sites, government facilities, convention centres, POS/kiosks, etc. Management access, from BIOS to applications, from any web browser anywhere, at any time is guaranteed.

Amazingly scalable, Spider is a complete KVM switch that can be easily daisy- chained together using Lantronix SwitchPort+ integrated Ethernet switch technology. This provides a cost-effective solution in environments where numerous cable drops and distance limitations can be a challenge when adding servers.

Rather than adding another more costly switch that forces administrators into pre-defined multiples, administrators can add remote IP users one server port at a time by simply deploying another Spider. And network reliability increases as there is no single point of failure with Spider deployments. If a unit is disabled, only access to that server is lost until the Spider is replaced.

SecureLinx Spider provides continuous availability to servers with 1:1 non-blocked, BIOS-level access. This allows administrators to have guaranteed access to mission critical servers regardless of how many of them need remote access. In other words, administrators are not “locked in” to a fixed number of remote users, and Spider offers an extremely low-cost-per-remote-user for guaranteed non-blocked access. And no client software or external power supply is required.

34 servers may require two 32-port KVMs or some combination that leaves unused ports, increasing the cost per port. With Spider, you can add one port at a time.

If a 32-port KVM unit fails, all access to those connected servers is lost. If a unit is disabled you lose access to just one server; and Spider is easily replaced.

If access to all 32 servers is through a single Ethernet connection and the switch port fails, access to all 32 servers is lost. Spiders can be cascaded or connected individually back to a switch. They can even be distributed among multiple switches so no single switch failure cuts you off from all your servers.

Most high-density solutions require purchasing dongles to connect to managed servers, increasing cost. Spider has the necessary HD-15 video, USB and PS/2 connections built in.

A typical high-density solution allows access to a limited number of managed servers at a time. (A high-end 32-port KVM may only allow as many as 8 servers to be accessed at once.) Each Spider allows one or more people to connect to a server. 32 Spiders means 32 simultaneous non-blocking connections - multiple users can access the attached server simultaneously!

Current CAT5-based solutions are limited to 50 to 150 feet between the switch and server. And image quality degrades with distance. With Spider, there are virtually no cable limitations and image quality doesn’t degrade with distance.

Switch-based solutions may require separate KVM and serial dongles and/or external power supplies. Spider is a completely integrated IP-based KVM switch that does not require an external power supply.
