One last note. Our vendor at the time we ordered our quad 12 core machines could only provide that mobo in a 1U chassis. Consequently we bought all external arrays for that machine. Since you're looking at a dual 8 core machine, you should be able to get a mobo like that in almost any chassis you want. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
