How valid are HP's claims of pre-eminence in SAP SD benchmarks? In a Sun Performance and Best Practices blog, Guido Ficco comments on significant SAP SD 2 Tier results and HP claims. According to Ficco, HP's claims rely on data skewed to establish their result. In defense of his position, Ficco cites the results for the latest version of SAP Enhancement Package 4 for SAP ERP 6.0 (Unicode).

Among the claims by HP that Ficco proposes to refute are:

HP is #1 in 8-processor, 4-processor and 2-processor servers in the following

• 8-processor: yes, but on Windows (8,280 SAP SD Benchmark users) and on Linux (8,022 SAP SD Benchmark users) with the HP Proliant DL785 G6 (8x 2.8GHz Opteron 8439 SE).

• Formally correct statements, Ficco concedes, pointing out, however, that HP fails to mention Sun holds the actual #1 8-processor overall record result by far, using Solaris at 10,000 SAP SD Benchmark users on a Sun Fire X4640 with eight 2.6GHz Opteron 8435, leading by more than 20% with lower clock speed.

• 4-processor: yes, but on Linux (4,370 SAP SD Benchmark users, using the HP Proliant DL585 G6, 4x 2.8GHz AMD Opteron SE.

• Again, formally correct statement, although HP fails to mention that Sun holds the 4-processor overall record result using Solaris at 4,720 SAP SD Benchmark users, obtained on a Sun SPARC Enterprise T5440 with four 1.6GHz UltraSPARC T2 Plus.

• 2-processor: Similarly HP claims the #1 and #2 rankings, but on Linux (3,171 SAP SD Benchmark users, HP Proliant DL380 G6, 2x 2.93GHz Xeon X5570) and (2,315 SAP SD Benchmark users, HP Proliant DL385 G6, 2x 2.6GHz Opteron 2435).

• Here, Ficco points out HP once again omits the fact that Sun holds the #1 2-processor overall record result on Solaris at 3,800 SAP SD Benchmark users obtained on a Sun Fire X4270 with 2x 2.93GHz Xeon X5570. A 20% and 64% Sun-leading result.

In light of the above claims, with the exceptions noted by the author, he determines that the only conclusion is that Sun Servers running Solaris have real leadership in the SAP SD Two-Tier Benchmark. This fact is not only confirmed for the 2- to 8-processor servers but also at the high-end where the Sun SPARC Enterprise M9000 with Solaris leads with the world record overall for this benchmark, showing real record performance and top vertical scalability.

HP is making claims of "leadership" in the Two-Tier SAP SD benchmark by carefully fencing the claims, Ficco concludes, based on the OS (Linux and Windows), and conveniently omitting the actual leading results from Sun on Solaris.
