Recorded on April 28, 2015 This week we are pleased to be joined by Alex Narvey of Precursor Systems, based in Winnipeg, Canada. Alex is known for promoting the RAIS concept, which is a method to maintain a "hot standby" server using Target Disk Mode and a mirrored RAID. R.A.I.S. stands for Redundant Array of Independent Servers. Alex's RAIS page is a wealth of resources and information, including products and services for your servers. According to Wikipedia, RAID originally stood for "redundant array of inexpensive disks" and is now commonly considered to mean "redundant array of independent disks". Joe's joke to start the show was originally considered pretty bad, and is now commonly considered to be just awful. Dealing with differing network hardware across two machines, e.g. Mac Pro with two Ethernet ports and Mac mini with one, sometimes it's easier to just manually intervene rather than engineer an automated solution. Doing something predictable, according to best practice, consistent with the expectations of an educated client or another consultant – rather than over-engineering a more "tricky" solution.
