Spreadsheet to calculate latency due to the speed of light over the distance between sites. This can be handy in calculating round-trip latency for data communications to distant DR sites, or between sites in disaster-tolerant clusters.

Sneak Peek Webcast for a planned Pre-Conference Seminar on Using OpenVMS Clusters for Disaster Tolerance. The Seminar itself was cancelled, but the Sneak Peek Webcast provided information on trends affecting Disaster Tolerance and Disaster Recovery, common questions and technology options for disaster-tolerant OpenVMS clusters, which technology options are most common in practice, and the crucial design choices involved in setting up a disaster-tolerant OpenVMS Cluster. Here are the Slides and Recording.

(If the current or peak number is at or near the total number available, you may need more RMS global buffers; if the peak is no where near the total available, you may have more global buffers allocated than you really need.)

I had the pleasure of helping set up the disaster-tolerant OpenVMS Cluster used in HP's Disaster Proof video in May of 2007. In this sequel to previous year's Bulletproof XP video (on YouTube or on HP's website), in which HP shot a bullet through a Storageworks XP storage array and demonstrated that it could continue working, uninterrupted, HP upped the ante for this video and took two datacenters' worth of equipment out to the test range at National Technical Systems, Inc. in Camden, Arkansas, who specialize in testing all sorts of things that go "Kaboom!", such as military munitions. There HP set up disaster-tolerant configurations for each of the operating system platforms it sells, all sharing Storageworks XP storage arrays, and then used 70 pounds of C-4 explosive to blow one datacenter to bits to prove the ability of its disaster-tolerant solutions to continue operating with zero data loss and with only a brief delay before continuing. This video may be seen on YouTube or on HP's website. A white paper describes the test.

More of my DECUS presentations, from earlier days, were once found at http://www.geocities.com/keithparris/ until Yahoo bought GeoCities and ended the free service. This site's contents may be accessible via http://reocities.com/keithparris/ or the Wayback Machine at Archive.org; if not, send me e-mail letting me know what you need; I have all the GeoCities content squirreled away.
If you need to use any of this material in your presentations, I'm happy to provide it in PowerPoint format -- just contact me via e-mail. I ran out of space to include the PowerPoint files for everything here.
