Shh! Disk drive at work.

Funny and provocative video (thanks David!) from Sun demonstrating 2 things: 15k drives are vibration sensitive - in this case to a shout a couple of inches away. That Sun's Fishworks analysis suite enables realtime analysis of storage behavior. Bad, bad, bad...

Many-cores hit the memory wall

Everyone in the data storage industry knows about the gap between I/Os per second of disk drives and processor I/O requirements. But there is a similar problem facing DRAM support of many-core chips. Named "the memory wall" by William Wulf and Sally McKee in their...

The new storage pyramid

OK, it is still a pyramid Predictions of the storage array's death struck some commenters as premature. Commenters raised a host of issues: Cost. Low-end storage arrays are cheaper than clusters. Complexity. The complexity of clustered hardware - all those cables and...

Stupid storage failures

Valiant but doomed The ZFS discussion thread had an interesting comment from Sun's Jeff Bonwick, architect of ZFS, on storage device failure modes. How do you know a disk or a tape has failed? You don't. You wait, while the milliseconds stretch into seconds and maybe...
