There has been a lot written about where to store cold data—data that is rarely if ever accessed. But there has been far less insight on how and where to store frequently accessed data--otherwise known as hot data. ITPro Today spoke with Laz Vekiarides, CTO and founder of ClearSky, on the unique needs of storing and accessing hot data.
ITPro Today What is your definition of hot data?
Vekiarides: Essentially, it’s any data an organization would access over the course of a week. Hot data tends to be anywhere from 7% to 12% of a company’s provisioned primary storage for a particular workload. We’ve actually measured it. I’ll never forget the first customer we ran the analytics on when we were first designing our system. We had half a petabyte of storage and found that, on average, they were accessing 5% to 7%.
