For those of you interested in high availability for databases, this week brought a whole flurry of DRBD related posts in the MySQL blogosphere.
To kick off the week, and perhaps surprisingly for some, Peter Zaitsev blogs about the superiority of DRBD over SAN based high availability for MySQL. The Percona folks seem to like our recently introduced support for Dolphin Express replication.
Then, Charlie Schluting kicks off a series of articles about High Availability for MySQL mentioning DRBD. He also adds a teaser for next week’s post in which he plans show you how to configure DRBD with HA to quickly set up redundant MySQL servers. Watch that too.
And finally the Giuseppe Maxia blogs about dispatching the myth of circular replication as a silver bullet scalability option, and explaining how DRBD works at the Open Source Conference in Athens, Greece this week.
I guess DRBD’s growth is no accident…
