One of the most common network bottlenecks are your server hardware. Your
servers should be powerful computers capable of handling all the work your
network will throw at them. Don’t cut corners by using a bottom-of-the-line
computer that you bought at a discount computer store.

| Hardware Bottlenecks |
The following are the four most important components of your server
hardware:
Processor: Your server should have a powerful processor. As
a general rule, any processor that’s available in a $500 computer from a store
that sells TVs and washing machines as well as computers is not a processor that
you want to see in your file server. In other words, avoid processors that are
designed for consumer-grade home computers. For optimum performance, your
servers should use server-class Itanium or Xeon processors.
Memory: You can’t have too much memory. Memory is cheap, so
don’t skimp. Don’t even think about running a server with less than 8GB of
RAM.
Disk: Don’t mess around with inexpensive SATA hard drives.
To be respectable, you should have nothing but SCSI drives.
Network interface: A $9.95 network card might be fine for your home network,
but don’t use one in a file server that supports 50 users and then expect to be
happy with the server’s performance. Remember that the server computer uses the
network a lot more than any of the clients, so equip your servers with good
network cards.
