Table 11.1 Comparing Client/Server <strong>and</strong> Peer-to-Peer Networking<br />

Continued<br />

Chapter 11—Networking<br />

Item Client/Server Peer-to-Peer<br />

Backup Centralized when data is stored Left to user decision; usually<br />

on server; allows use of high- mixture of backup devices <strong>and</strong><br />

speed, high-capacity tape<br />

backups with advanced<br />

cataloging.<br />

practices at each workstation.<br />

Redundancy Duplicate power supplies, hot- No true redundancy among<br />

swappable drive arrays, <strong>and</strong> either peer “servers” or clients;<br />

even redundant servers are failures require manual intervencommon;<br />

network OS normally tion to correct with high possicapable<br />

of using redundant<br />

devices automatically.<br />

bility of data loss.<br />

If you choose any form of Ethernet network hardware for your<br />

peer-to-peer network, you can upgrade to a client/server network<br />

later by adding a server with the appropriate network operating system.<br />

Your existing network cards, cables, <strong>and</strong> other hardware can<br />

still be used with the new server.<br />

Choosing Network Hardware <strong>and</strong><br />

Software<br />

In this section, you’ll receive a detailed checklist of the hardware<br />

<strong>and</strong> software you need to build your network. Although many<br />

options are available on the market for network hardware, this discussion<br />

assumes that you will be choosing Fast Ethernet hardware<br />

that can also work with st<strong>and</strong>ard Ethernet networks (“dual-speed”<br />

10/100 cards <strong>and</strong> hubs). This is the most popular <strong>and</strong> cost-effective<br />

network currently available.<br />

First, start with the number of computers you plan to network<br />

together. You need the items discussed in the following section to<br />

set up your network.<br />

NIC<br />

One network interface card (NIC) is required for every computer on<br />

the network. To simplify technical support, buy the same model of<br />

NIC for each computer in a peer-to-peer workgroup network.<br />

Today, the best price-performance combination is Fast Ethernet<br />

(100BASE-TX) NICs. You should choose dual-speed (10/100) versions<br />

of these cards to enable interconnection with st<strong>and</strong>ard<br />

10Mbps Ethernet networks.<br />

You should record the br<strong>and</strong> name <strong>and</strong> model number of the<br />

NIC(s) you are using, as well as the driver version or source. Use<br />

Table 11.2 as a guide.
