11: <P>
12: There are 4 hardware requirements for the current LON-CAPA system.
13: <UL>
14: <LI>i586 (or greater) intel architecture computer
15: <LI>ethernet card
16: <LI>static IP connection
17: <LI>4 gigabytes (or greater) hard drive space
18: <LI>CD-ROM
19: <LI>64 megabytes (or greater) of RAM
20: <LI>all hardware (monitors, ethernet cards, CD-ROMs, motherboard) must
21: be compatible with RedHat Linux 6.2. A vendor compatibility list is at
22: <A HREF="http://www.redhat.com/support/hardware/intel/62/rh6.2-hcl-i.ld.html">http://www.redhat.com/support/hardware/intel/62/rh6.2-hcl-i.ld.html</A>.

27: <H3>Frequently Asked Questions</H3>
28: <P>
29: <OL>
30: <LI><B>Why can't I run the LON-CAPA system on a Sun Microsystem,
31: MacOS-X, Windows-NT, or a LINUX-based system other than RedHat 6.2?</B>
32: <BR>The short answer is you can run LON-CAPA on most any type of
33: computer, but you shouldn't. The software system of LON-CAPA has
34: been designed with security and performance in mind. Unless you are
35: prepared to understand the configuration details of the LON-CAPA network
36: layer and security issues specific to your operating system and machine
37: architecture, you will not be able to run LON-CAPA. In the long-term,
38: alternate scenarios of running the LON-CAPA system will add significant
39: administrative overhead in terms of LON-CAPA software upgrades.
40: <LI><B>What about firewall configurations?</B>
41: <BR>Firewall configurations are doable, but not recommended.
42: This requires detailed understanding of the LON-CAPA network layer, reduces
43: network connectivity, and may require reconfiguration upon new software
44: releases
45: <LI><B>What about load-balancing hardware configurations?</B>
46: <BR>The good news is that LON-CAPA supports its own load-balancing
47: of web-delivered content.
48: <LI><B>What about backup tape drives and CD-ROM burners?</B>
49: <BR>There currently is no defined system of backing up LON-CAPA resources.
50: It is, however, both easily doable and highly recommended.
