Bad performance on Proliant DL580 G4 2007-05-28 - By Herman.Maseberg@(protected)
Back
Hi, recently we migrated from IBM xSeries 445 Suse SLES 9 (32 bits) with 9
GB RAM to HP DL580 G4 SLES9 (AMD64/EM64T) with 16 GB RAM, in both cases
attached to a external FC storage (Hitachi AMS500) running SAP 4.7 on
Oracle 9.2.0.7.
In boths cases we use ext3 filesystems mounted with the writeback option.
After migration we don't see visible better performance and I suspect some
of the hardware components (HBA or ethernet cards) is responsible for the
unexpected performance.
The question is, anyone have the same servers or configuration and have
some tip to help us improve performance?
Thanks!
