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.
