Pushing Mnesia further

Luke Gorrie writes on Lambda The Ultimate about using Mnesia - the open source database written in Erlang - on large volumes of data:

We have pushed it to >60M records using a custom backend of BerkeleyDB stored on a cheap 12-disk SCSI array. Mnesia scalability is everything in our telecom system since we store one record per subscriber and lots of operators have tens of millions of subs.

With the disk arrays we do blow out to 8U of rack space for a full cluster but it still looks comical compared with the racks and racks that make up Java/Oracle systems at these sites :-)
