AIX 5.2 can be run in 32 and 64-bit mode. 64-bit kernel mode should have better performance on bulk I/O, larger memory model, etc.
This is definitely worth if if you are using ultra 160 or 320 adapters, or 64-bit Fibre channel (6228 and 6239) cards. I would think that for an M80, any LPAR capable system, any 7017 system, Winterhawk and Nighthawk SP nodes, and similar class machines would greatly benefit from 64-bit. If your system only has 32-bit PCI adapters, there wouldn't be much benefit in 64-bit kernel mode. --- Josh Davis On 04.03.22 at 15:41 [EMAIL PROTECTED] wrote: > Date: Mon, 22 Mar 2004 15:41:58 +0100 > From: "Loon, E.J. van - SPLXM" <[EMAIL PROTECTED]> > Reply-To: "ADSM: Dist Stor Manager" <[EMAIL PROTECTED]> > To: [EMAIL PROTECTED] > Subject: Re: Advantages / Disadvantage running in 64 bit mode > > Hi James! > Please correct me if I'm wrong, but as far as I know, you can run AIX > 5.2 in 32-bit mode.
