Xen with DRBD, GNBD and OCFS2 HOWTO
This HOWTO covers a Xen setup that allows the live migration of virtual machines (domU's) from one physical machine to another. The easier but far more expensive way to achieve this would be to get a SAN and some fibre channel attached hosts. But this setup allows you to build your own redundant storage network with common PC hardware.

Apache2, WebDAV, SSL and MySQL: Life In The Fast Lane LG #131
As part of my work I had to set up an upload/download site for our customers with the following brief: * Part of the Web site would have to be accessible by anybody * Another part of the Web site would need authentication in order to download software, patches, etc... * Some of the customers should be allowed to upload files on the Web site - but within a set quota. * Uploading, downloading and managing the Web site content would have to be easy - and it was decided that it would have to be done via HTTP for several reasons: 1) in some organizations FTP isn't always allowed and active FTP can sometime cause a problem with firewalls. 2) using SFTP or SSH to manage the site would require specialized client software. We chose to use WebDAV with a patched version of the Apache 2 WebDAV module, since we needed quota functionality. Additionally, all the WebDAV traffic and authentication was to be done via HTTPS. This was required because Windows XP clients simply refuse authentication of a WebDAV directory, and in any case has the benefit of making the management of the site far more secure regardless of the WebDAV client and platform used. One thing to bear in mind is that I had to use Apache 2 instead of Apache 1.3.x as there is no WebDAV patch for Apache 1.3.x. The following article will explain how to set up and configure Apache 2, HTTPS, WebDAV. In addition, it will demonstrate how to recompile the WebDAV module to support quota and how to use MySQL to provide authentication and give arbitrary access control to the various part of the site.

WebDAV on Apache2
WebDAV is a way of making parts of your webserver writable to certain clients. There are obvious reasons why you might want to do this, such as making it easy to update a website, and less obvious reasons, such as sharing Calendar data, or sychronising your bookmarks in Firefox, or to supply a small amount of password protected web space for people to share documents.
