Virtually no overhead Solaris Zones, ex: SAP-SD on T2000
Wednesday May 31, 2006
Virtualization and consolidation is of course a hot topic -- and it has been for a while. Sun's been leading the charge over a decade with domains and now zones. People often seem to ignore overheads or not talk about measured performance when talking about consolidation.
...Here is some data that proves Solaris zones have virtually no overhead. Sun ran has audited results on the SAP-SD benchmark using Solaris 10 on the Sun Fire T2000.
- The Sun Fire T2000 server with UltraSPARC T1 processor running 4 zones was within 1% of the performance of running a single zone on the SAP-SD 2-tier benchmark.
- To be clear, the performance difference between the single and 4 zone results was due to the SAP overhead of supporting 4 central instances each with its own database instead of 3 instances plus a central instance sharing a single database.
- The Sun Fire T2000 with 4 zones supported total 940 SD Benchmark Users, using Open Source MaxDB Database (MySQL Distributes MaxDB). In comparison, the Sun Fire T2000 (no zones) had 950 SD Benchmark Users, using Open Source MaxDB Database.
- The Sun Fire T2000 4 zones SD Benchmarks were running simultaneously, using zone setup with pool/processor set.
In case you get confused, we actually had 4 results on www.sap.com/benchmark, but as you can see they were all run at the exact same time.
The SAP Standard Application SD (Sales and Distribution) Benchmark is a two-tier ERP business test that is indicative of full business workloads of complete order processing and invoice processing, and demonstrates the ability to run both the application and database software on a single system. The SAP Standard Application SD Benchmark represents the critical tasks performed in real-world ERP business environments.
...anyone have any measurements of VMWare's overhead they can share with us? Comments open...
