Siebel on Sun CMT hardware : Best Practices

The following suggested best practices are applicable to all Siebel deployments on CMT hardware (Tx00, T5x20, T5x40) running Solaris 10 [Note: some of this tuning applies to Siebel running on conventional hardware running Solaris]. These recommendations are based on our observations from the 14,000 user benchmark on Sun SPARC Enterprise T5440. Your mileage may vary.

Siebel 8.0 on Sun SPARC Enterprise T5440 - More Bang for the Buck!!

Recently Sun announced the 14,000 user Siebel 8.0 PSPP benchmark results on a single Sun SPARC Enterprise T5440. An Oracle white paper with Sun's 14,000 user benchmark results is available on Oracle's Siebel benchmark web site. The content in this blog post complements the benchmark white paper.

Some of the notes and highlights from this competitive benchmark are as follows:


Based on the above notes: Sun SPARC Enterprise T5440 is inexpensive, requires: less power and data center footprint, ideal for consolidation and equally importantly scales well.

Vendor-to-Vendor comparison

How does Sun's new 14,000 user benchmark result compare with the high watermark benchmark results published by other vendors using the same Siebel 8.0 PSPP workload?

Besides Sun, IBM and HP are the only other vendors who published benchmark results so far with the Siebel 8.0 PSPP benchmark workload. IBM's highest user count is 7,000; where as 5,200 is HP's. Here is a quick comparison of the throughputs based on the results published by Sun, IBM and HP with the highest number of active users.

Sun Microsystems' 14,000 user benchmark on a single T5440 outperformed:

From the operating system perspective, Solaris outperformed AIX, Windows Server 2003 and HP-UX. Linux is nowhere to be found in the competitive landscape.

A simple comparison of all the published Siebel 8.0 benchmark results (as of today) by all vendors justifies the title of this blog post. As IBM and HP do not post the list price of all of their servers, I am not even attempting to show the price/performance comparison in here. On the other hand, Sun openly lists out all the list prices at store.sun.com web site.

CAUTION

Although T5440 possesses a ton of great qualities, it might not be suitable for deploying workloads with heavy single-threaded dependencies. The T5440 is an excellent hardware platform for multi-threaded, and moderately single-threaded/multi-process workloads. When in doubt, it is a good idea to leverage Sun Microsystems' Try & Buy program to try the workloads on this new and shiny T5440 before making the final call.



I would like to share the tuning information from the OS and the underlying hardware perspective for couple of reasons -- 1. Oracle's benchmark white paper does not include any of the system specific tuning information, and 2. it may take quite a bit of time for Oracle Corporation to update the Siebel Tuning Guide for Solaris with some of the tuning information that you find in here.

Check the second part of this blog post for the best practices running Siebel on Sun CMT hardware.
