64-bit OS support in Domino 7.0.2
October 18 2006
Domino 7.0.2 adds support for Microsoft Windows x64 and Novell SLES 10 (32- and 64-bit). Domino now supports 64-bit versions of Windows, Linux SLES 9 and SLES 10, Red Hat Linux 4, Solaris, AIX, and i5/OS.
64-bit operating systems provide Domino with access to additional addressable memory space. In our benchmark tests, we have seen that Domino running on Windows x64 can reduce CPU load, compared with its 32-bit operating system counterpart. With Win32, the default memory available to each Domino partition is 2 GB. There is a switch to increase memory to 3GB, but that solution requires a 10% CPU hit to manage the additional memory. With Windows x64 and Domino 7.0.2, this switch is not needed and the extra memory is supported by default.
Offering 64-bit operating system compatibility now gives you the opportunity to start deployment of Domino on 64-bit OS today. It also allows you to start laying the groundwork for the planned native 64-bit port of Domino, which will enter beta testing at the same time that Hannover and Domino Next ship. (More details on native 64 bit plans coming to this blog soon!)
There is also a very useful frequently asked questions document published in a recently updated 64-bit Domino technote. This note is well worth a read for more details on 64-bit operating system configurations supported today and some planning information for Domino native 64-bit.
