Pat, Node is a combination of CPU, memory and IO. While it will obviously highly rely on the existing individual pieces it also has its own specific considerations. For example, if you add a node that has both CPU and memory you want to add the memory before the CPU for obvious performance issues down the line. hth - Martine -----Original Message----- From: hotplug_sig-bounces@xxxxxxxxxxxxxx [mailto:hotplug_sig-bounces@xxxxxxxxxxxxxx] On Behalf Of Patrick Mochel Sent: Wednesday, December 08, 2004 11:39 AM To: Tom Hanrahan Cc: hotplug_sig@xxxxxxxxxxxxxx Subject: [hotplug_sig] Re: [Hotplug_sig] Hotplug Testing On Wed, 8 Dec 2004, Tom Hanrahan wrote: > Memory hotplug is first, but we also want to start thinking about CPU > and device hotplugging. Later we'll add in node hotplug. What is 'node hotplug'? (node is perhaps *the* most overused term in computing today). Thanks, Pat
