Acc. to SUN and its partners, the newest firmware for the V20z and V40z is supposed to provide faster memory operations. We were told that atleast in one case, some memory tests indicate as much as 65% faster memory operations. Also, this version of BIOS will allow systems to use larger size DIMMS so I can pack 64GB of memory in my 40z when 4GB DIMMS become available.
The V20z updated firmware (platform BIOS) is release V1.33.7.2 The V40z updated firmware (platform BIOS) is release V2.33.7.2 The updated network shared utilites volume (NSV) is release V2.3.0.11 (The update server Java app that does the install is still V2.2.0.6.)
One of my Engineers, Dan G. performed nbench benchmarking of the new firmware. All credits on this should go to him. He found that the atleast using nbench, the improvement is negligible. The results are below: (an hackjob by openoffice to convert excel into html)
Technorati Tags: SUN, nbench, Linux
Dan Gomez: These are the results gathered from 'nbench' to determine if the firmware upgrade on the v40z Opteron “atlas” had any impact on memory performance. (10-18-05) |
Summary: the results show the firmware had no impact on memory performance |
