Professional smart guy Mike Dutch from the office of the CTO in EMC Storage Software Group (SSG) has an interesting post up on Backup And Beyond about Storage Tiers. How we think of them today and perhaps how we should think of them going forward.

Here’s a snippet:

Should deduplicated storage be considered a storage tier?  I would say “no” and here’s why: because a technology such as deduplication can span, and optimize across all tiers.

A storage tier is storage space that has availability, performance, and cost characteristics different enough from other storage tiers as to economically justify the movement of data between it and other storage tiers based on the importance (value, performance need etc…) of the data. While storage tiers are often thought of as being tied to a particular type of hardware, e.g.  Flash, FC, SAS, SATA, VTL, PTL, COM (Computer Output Microfiche), or even paper, this is not necessarily the case. For example, highly available cloud or network-based virtual disks could leverage multiple technologies within their single tier.

You can get more at the source. And hopefully this won’t be Mike’s last foray into the store-o-sphere.
