Hardware Server design Design decision Physical safety of servers Improve server situation Uptime Dual-Booting issues Methods of installation BEFORE THE INSTALLATION

Hardware Compatibility List (HCL): Red Hat Caldera Hardware

Significant issues: Stability Availability Performance Server design

The most significant design decision to make when managing a server configuration is not technical, but administrative. The server designed should have a good environment. Design decision

Server design should not be user friendly: No multimedia tools. No sound card support. No distracting web browsers. Design decision

Physical safety of servers Keep servers in a separate, physically secure room. Restrict server access for non-administrative personnel only through the Network. Install a battery backup.

Improve server situation Avoid starting X Window until required. Determine what functions you want the server to perform and disable the other functions. Linux allows tailoring of the kernel.

Uptime command provides: Duration of the system since its last boot. Number of users currently logged in. Load the system is experiencing. Uptime

Dual-Booting issues Windows 95 or Windows 98 – use the fips.exe. Windows NT – move some of the data around manually to free a partition.
