Big Honkin' Databases

Most of the world's largest databases still hum along on Unix, but Linux and Windows can hang in the big leagues. Just look at Inc., which has one Linux-based data warehouse that's more than 24 terabytes in size and another with more than 18 terabytes.

Those are among the tidbits delivered by Winter Corp., a consulting firm specializing in large databases that every other year produces one of the IT industry's best gee-whiz lists.

The largest commercial database (Yahoo Inc.) exceeds 100 terabytes, triple the largest commercial data warehouse in 2003. The hardest-working database processes more than 1 billion SQL statements per hour. Beyond business, the biggest database Winter found: a 222.8-terabyte monster at the Max Planck Institute for Meteorology.
