eBay keeps up with evolving storage demands

Few businesses have grown as rapidly as eBay. Its founder and chairman, Pierre Omidyar, built the online trading bazaar in his living room in one weekend in September 1995 with hardware that could be purchased at Fry's Electronics. Every sale item was a separate file, generated by a Perl script, and the system maxed out at 50,000 active items. Search functionality was nonexistent and storage was internal, directly attached. Fast forward to 2007 and eBay now has 212 million users and 584 million listings. On a typical day, there are 1 billion page views and 26 billion SQL queries, which averages out to 6,000 SQL transactions per second, per database. William Crosby-Lundin, eBay's SAN and high-availability infrastructure manager, says only 12 people manage eBay's storage, which consists of 13 discrete SANs that each offer a different quality of service for performance, availability and cost.

    Backup and recovery applications typically include reporting capabilities, but they're often rudimentary and provide only basic information on the success or failure of data protection operations. Data protection and recovery management (DPRM) products, an emerging class of monitoring and planning tools, fill in the gaps where traditional backup apps fall short. DPRM tools provide advanced capacity reporting, predict usage patterns and allow performance tuning, troubleshooting and cost management. Here's how to pick the best product for your shop.

  • Can iSCSI crack the enterprise?

    by  Stephen Foskett

    iSCSI storage systems are showing up in medium-sized businesses, but storage managers at large enterprise shops have been reluctant to embrace them.

  • Best Practices: The ultimate archiving challenge

    Given current practices, it's questionable whether electronic information created and stored today will be usable 10 years or 15 years from now. The steps we take now will greatly affect the magnitude of the problem facing us (or our successors) in the future.
