DRBD is supposed to work between different hardware, and different architectures. so you could connect a PPC with a i386, or an ia64, no worries. note however that the storage subsystems should be roughly in the same performance ballpark, though, as a slower Secondary will slow down any Primary. If you intend to use this as a failover cluster, both nodes should overall be in the same RAM/CPU/Performance league, or you will suffer when you actually need to run your services on the less powerfull node. depending on the applications in use, it may be advisable to have the same architecture on both nodes. DRBD does not care for the architecture of the nodes, it should "just work". They absolutely have to have the same video card, though. :) -- : Lars Ellenberg : LINBIT HA-Solutions GmbH : DRBD®/HA support and consulting http://www.linbit.com DRBD® and LINBIT® are registered trademarks of LINBIT Information Technologies GmbH __ please don't Cc me, but send to list -- I'm subscribed
