Recently we conducted a Performance Proof of Concept for a large customer using the new 8 Intel Nehalem-EX E7540 8-core processor HP DL980 G7 server. This blog discusses some of the configurations and tuning conducted during the PoC. One HP DL980 with 512GB of RAM was used for SQL Server and 9 x 2 Intel Nehalem-EP 5670 processor were used as application servers.
