scale-up servers. At the core of the HP PREMA Architecture is a node controller ASIC, derived from Intel technology
powering the HP Integrity Superdome 2.
The HP PREMA Architecture provides these particular benefits for processing and data-intensive BI workloads:
 Smart CPU caching: Achieves up to 20% better processor scaling than competitive 8 socket systems by reducing
processor overhead *
 Resilient system fabric: Provides 50% more interconnect capacity and dynamic traffic routing capability for
improved performance in highly concurrent, highly parallel BI workload environments*
The DL980 provides an excellent platform for scaling data warehouse or data mart solutions. The following
information provides detailed setup recommendations used in our reference configuration.
When setting up the DL980 please make sure to review the BIOS settings listed in Appendix 1.
The recommend layout of the fibre channel cards in the DL980 is shown in figure 5. There were (10) PCIe x8 slots
and (2) PCIe x4 slots used. For an 8Gb DP FC HBA a PCIe Gen2 x4 slot will provide plenty of bandwidth and will
not be a performance bottleneck.
* Based on HP internal engineering benchmarks.
