Linux File System -- Analyzing the Fsck Test Results

The results of our Linux fsck testing were posted last month. Now it's time to address the big questions that remain: What do the results tell us, what do they mean, and is the performance expected?

Linux File System Fsck Testing -- The Results Are In

Our Linux file system Fsck testing is finally complete. Just how bad is the Linux file system scaling problem?

The Future of Storage: Devices and Tiering Software

The only constant about storage technology is the fact that it is constantly changing. But where is it headed? Storage devices and tiering software are two areas ripe for speculation.
