Solution Type Technical Instruction Sure Solution 1010271.1 : Sun Enterprise Servers: How to populate CPU Processors/Modules and Memory DIMM's For best performance
PreviouslyPublishedAs 214100 Description Populating CPU Processors/Modules and Memory DIMM's for best performance Utilize the Sun System Handbook and the following information if there are questions related to best practice advice for configuring a Sun Enterprise Classic Server for best performance. Steps to Follow For best performance populate CPU Processors/Modules and Memory Dimms as follows: Ultra Enterprise 3x00, 4x00, 5x00, 6x00 Systems: Processors: Fill all PROC 0 locations on all CPU/Memory boards before filling any PROC 1 locations. After all PROC 0 locations are filled, you can begin filling the PROC 1 locations, again starting from the lowest slot number to the highest. Mixing processor speeds within a system is not permitted. Mixing processor cache sizes within a system is permitted, to be able to mix cache sizes within the same system board the OBP needs to be at 3.2.21 or higher. (use the latest version of patch 103346 to update the OBP if the boards are currently downrev). Memory Dimms: When adding memory fill group 0 across all system boards beginning with the first system board, then proceed to fill group 1 across all system boards. Begin with the largest density banks first (256 Mbyte SIMMs), continue with medium sized bank (128 Mbyte SIMMs, then 32 Mbyte SIMMs), and finish with the smallest banks (8 Mbyte SIMMs). SC1000, 1000E, 2000, 2000E Systems: First populate cpu location "A" across all system boards beginning with the first system board, once location "A" is filled across all system boards, then populate location "B" across all system boards again beginning with the first system board. Do not mix CPU module speeds within a system. Mixing CPU module cache sizes is permitted within a system but not within the same system board. Memory Dimms: When adding memory fill group 0 across all system boards beginning with the first system board, then Group 1 on all system boards, followed by Group 2, and Group 3.

The document is not likely to get many hits - but the information is still relevant...but only for another year or so. Date: 2004-12-07 User Name: 18392 Action: Approved Comment: Since quite a bit of this information seems to be in manuals, and these systems are getting out-of-date, I recommend this document should be archived at next review.
