Summary

Data Network

The Datashed network is designed around the following rough organization:

• Each rack has one or more top-of-rack Ethernet switches. All of these are Foundry FastIron Edge models (2 x448, 1 4802).
• The ToR switches connect to the core switch, sw-core-01, via redundant multimode fiber optic links.
• The core switch does inter-VLAN routing for the entire network.
• The core switch is also uplinked to the core router, rt-core-01.
• The core router can get packets to and from the non-Ethernet segments of the network (Token Ring, ATM, FDDI, etc.), as well as to the edge routers.
• The edge routers handle connectivity to the Internet, via the GTT T1 line on rt-edge-01 and the ZiaNet ADSL on rt-edge-02.
• The core router is also connected to the ChivaNet router, rt-chivanet-01, which acts as a firewall, router, and NAT device for ChivaNet WISP clients.
• VPN access from the outside is provided by a Cisco ASA-5520, called fw-edge-01.
• The house has a closet, called the IDF, which contains sw-tor-04, a Foundry FastIron Edge x448, uplinked to the datashed by way of 2x Cat5e cables running through conduits (this is changing soon).
• The IDF also contains an Arris DOCSIS modem/router, which handles connectivity to the Internet for non-hosting devices through Xfinity Cable.

Voice Network

The voice network is built around an AT&T Merlin Legend PBX:

• Connectivity to the house is provided by 2x 25-pair Cat3 cables, running through conduit.
• The cross-connect fields are 66 blocks, as I prefer them to 110 blocks for various reasons.
