ServerNet Fabric

A ServerNet fabric is a collection of connected routers and ServerNet links that form an

internal or external network. Two separate, identically configured fabrics, called the X

fabric and the Y fabric, together provide a fault-tolerant interconnection for the

ServerNet network.

Each processor connects to both fabrics. Typically, ServerNet adapters also connect to

both fabrics. The X fabric and the Y fabric are not connected through routers to each

other. A ServerNet packet cannot cross from one fabric to the other.

Networking

This subsection introduces the following terms and concepts related to networking:

Ethernet

Ethernet is a standardized way of physically connecting computers and devices such

as workstations and printers together to create a local area network (LAN). It is the

most common way to set up a LAN. Ethernet specifies what kind of cables must be

used, how the cables can be connected together, how long the cables can be, and how

the computers transmit data to one another using the cables.
