Sometimes, it is helpful to have a product certified against various testing and certification bodies, or have white papers written recommending a particular configuration. This can help in formal vendor processes such as IBM's system assurance review, and it can help managers decide that they can simply have confidence in a solution they are considering.
This page documents the certifications and white papers we know about for Linux-HA.
IBM's IRES product (IBM Retail Environment for SUSE Linux) configures DB2 on top of DRBD and Linux-HA. IBM's Doug Rothert can provide more details on request.
Linux-HA is TotalStorage Proven when used with Red Hat Enterprise Linux 3, or SUSE/Novell SLES9 (this page refers to Linux-HA as "Linux HA").
Emageon (an IBM Storage reference customer), bases their product line on Linux-HA on FasTT hardware. As of June 2004, they have over 40 such production installations, and the whole configuration is FDA-approved and certified. They have a few different FasTT configurations which they test extensively before each release of their system.
IBM has written a white paper recommending DB2 and Linux-HA for telecommunications applications based on FasTT hardware. This paper is the result of prototyping and testing this configuration by IBM's software group.
