DL980 system setup
When setting up the DL980 for an Oracle database there are a few best practices that will provide
improved performance and proper configuration.
 If the DL980 G7 has 1.0TB or more of RAM, the BIOS System Address Mode should be set to
44-bit. By default this is set to 40-bit.
 Spread the same size DIMM memory evenly across all memory cartridge sockets for maximum
performance. For the two 4-socket configurations it is best to populate all memory slots associated
with those four CPUs. For the 8-socket configuration install memory DIMMs across all memory
sockets of the eight CPUs for optimum NUMA performance.
 Use only dual or quad rank DIMMs as they are faster than single rank DIMMs.
 Configure per DL980 best practices to minimize memory latencies.
 If the application has parallelism that will work optimally with Hyper-Threading, leaving it enabled
in the BIOS could result in significance improvement. If not, Hyper-Threading can cause a drop in
overall performance. We saw up to 30% improvement in our testing by turning Hyper-Threading
on. Make sure to test it for your particular workload.
 Use the PCI-Express x8 slots for critical disk I/O.
 If connecting three or more HP VMAs, for optimal performance install the Low Profile PCIe
expansion option.
 Distribute PCIe pass-thru cards evenly across the available I/O bays and I/O hubs.
 Install and configure the NUMA packages.
