About this interactive

The lesson opens real equipment. Inside a server: mirrored drives, hot-swap fans, two power supplies, and a PERC card that manages RAID across the drives. An enterprise server would also have two network cards. Inside a switch: two power supplies and two fans. Some redundancy has to be built from separate devices. Cisco StackWise cables link several switches through their backplanes so they act as one switch, and the stack keeps running if one switch fails. Two ASA firewalls joined by a heartbeat check on each other constantly, and if one stops answering, the other becomes the live firewall. Some redundancy is components within the equipment; some you set up between pieces of equipment.
