eBay isn't a big user of storage virtualization. "It's vital [for us] to know what disk groups are working on behalf of which databases, and in which clusters they're in so we can deliver on our SLOs [service-level objectives] and diagnose problems," says Crosby-Lundin.
To keep up with anticipated growth, the company plans to add more automation to the process of storage provisioning and is working on "ways to better map storage performance and cost to the value it provides to the business," says Paul Strong, a distinguished engineer at eBay Research Labs.
What's on eBay's storage wish list? Pretty much what every storage manager wants: a cheaper SAN, improved availability and improved interoperability.
