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.

- OpenVMS Advanced Technical Bootcamp 2008, Nashua, NH, May 2008:
- 2-day pre-conference seminar on
Disaster Proof: How to Design, Build, and Test a Disaster-Tolerant OpenVMS Cluster [PPT]
[PDF]
featuring the videos
"Bulletproof XP",
"Making of the Bulletproof XP Video",
"Disaster Proof",
"Disaster Proof Documentary: Behind the Scenes",
and "Disaster Proof Slide Show".
- 3-hour block of Disaster Tolerance-related sessions covering the topics of
How the Disaster Proof OpenVMS Cluster Recovered So Fast, and How Yours Can, Too and
Simulation and Testing of Long-Distance DR/DT Configurations [PPT]
[PDF]
- 3-hour block of RMS-related sessions covering the topics of
Detecting and Solving Performance Bottlenecks Using Locking Data and
Sizing RMS Global Buffers [PPT]
[PDF] including
GLOBAL_BUFFER_USAGE.COM,
a DCL command procedure to examine RMS Global Buffer usage
for purposes of sizing (choosing the appropriate number of RMS global buffers for a given file),
It shows the current, peak, and total number of RMS global
buffers for each file which is open on an OpenVMS system.
(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 last 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.
