<h2><a name="_Toc421867153">General information on LON-CAPA Server Hardware
Requirements</a></h2>

<p>For full-time, classroom usage, an adequate LON-CAPA server should be/have: </p>

<ul type=disc>
 <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;
     mso-list:l0 level1 lfo1;tab-stops:list .5in'>a multiprocessor machine,</li>
 <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;
     mso-list:l0 level1 lfo1;tab-stops:list .5in'>a CPU speed of 1 gigahertz,</li>
 <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;
     mso-list:l0 level1 lfo1;tab-stops:list .5in'>a gigabyte of memory,</li>
 <li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;
     mso-list:l0 level1 lfo1;tab-stops:list .5in'>and at least 40 to 80
     gigabytes of hard disk space.</li>
</ul>

<p>A lesser machine can be used for toying around with LON-CAPA (LON-CAPA will
run for a single user on most any machine). </p>

<p>LON-CAPA servers experience significant peaks of activity before a homework
submission deadline. To support these critical peaks of activity, it is
strongly advised that LON-CAPA machines fit the above recommendation. </p>

<p>If thousands of students start accessing the box as a web server... well you
may want to consider more options. The design of the LON-CAPA system is to
naturally and transparently load-balance on multiple computer clusters. So, a
simple solution for running an entire college campus is to just have an adequate
plurality of LON-CAPA servers rather than a single, particularly monstrous
server. </p>

<p>We like to think of high web server usage as &quot;a good problem&quot;
though.... </p>

<h2><a name="_Toc421867154">Additional Information on LON-CAPA Server Hardware
Requirements</a></h2>

<p>LON-CAPA works nicely (for development purposes) on a Pentium II, 20
gigabytes of hard-disk space, 256M RAM, and 400MHz. The consensus is though,
that this may only be adequate for a class of a dozen students. </p>

<p>If you are making a serious investment, you should join the LON-CAPA mailing
list by visiting http://mail.lon-capa.org/mailman/listinfo/lon-capa-users. By
posting to this mailing list, you can learn about the solutions have worked for
others. </p>

<p>LON-CAPA works on any Intel-based RedHat-compatible hardware. Unlike other
e-learning software systems, it works comparatively well on dusty old crippled
machines without much RAM or processing. </p>
