#Pcworld file deduplicator series

Files re-opens are temporally related.Over 66 percent are re-opened once and 95% fewer than five times. Fewer than 50 percent are deleted within a day of creation. Files live an order of magnitude longer.File sizes are up to an order of magnitude larger.

Most bytes transferred are from larger files.

These runs are an order of magnitude larger.

Most bytes are transferred in longer sequential runs.

Read-write access patterns have increased 30-fold relative to read-only and write-only access patterns.

Read to write byte ratios have significantly decreased.

Both of our workloads are more write-oriented.

This paper was a collaborationbetween researchers from University of California Santa Cruz and our friends at NetApp.Here's an excerpt from the study: Compared to Previous Studies:

Let's start with some interesting statistics.Fellow blogger Robin Harris on his StorageMojo blog has an interesting post:,which discusses the findings of study titled"Measurement and Analysis of Large-Scale Network File System Workloads".

Here's another short 2-minute video, on Information Retention

This post will focus on Information Retention, the third of the four-part series this week. The launch was presented at the IBM Storage and Storage Networking Symposium to over 400 attendeesin Montpelier, France, with corresponding standing-room-only crowds in New York and Tokyo. In Monday's post,, I explained how this strategic initiative fit into IBM's New EnterpriseData Center vision.
