Endpoint turns a Linux machine with one or more FireWire cards into an SBP-2 device. One can use any physical block device or file (disc image) as storage. With multiple clients, each can potentially access the SBP-2 devices from a unique FireWire bus and utilize the full bandwidth of that bus.
GNS3 is a graphical network simulator that allows you to design complex network topologies. You may run simulations or configure devices ranging from simple workstations to powerful Cisco routers. It is based on Dynamips, an IOS emulator which allows users to run IOS binary images from Cisco Systems and Pemu, a PIXOS emulator to emulate PIX firewalls.
