eBays storage engineering team ("Eleven people," Strong said) utilizes 2 petabytes of raw digital space on a daily basis to run the site and store its data, yet has to add about 10 terabytes (or 75 volumes) of new storage every week to cover new transactions, Strong said. That follows alongside the eHarmony story: That highly successful social networking site has to purchase additional storage about every 90 days.
eBay said it uses a traditional grid computing system with the following features to build the site:
- about 170 Win2000/Win2003 servers
- about 170 Linux (RHES3) servers
- three Solaris servers: build and deploy eBay.com to QA; compile Java & C++; consolidate/optimize/compress XSL, JS and HTML
- time to build site: was once 10 hours; now only 30 minutes
- in the last 2.5 years, there have been 2 million builds.
