Dave is a technical consultant with EMC. As you can imagine Dave’s blog articles mainly deal about Storage and storage related topics like FCoE and 10GbE. But Dave also writes about the Cloud, which is also heavily tied to Shared Storage of course.
I just grabbed a couple of outtakes to give you an example of what Dave writes about:

Storage within the cloud is meaningless without a measurable level of performance that it can be compared against. Since there are no established benchmarks that determine performance of storage within a cloud infrastructure, it is reasonable to apply tiering metrics to storage based on content valuation and service level agreements (SLAs) and utilize this as an overarching methodology to judge COSS storage capabilities based on application set.

Policy is enacted on this movie object such that it is automatically moved from Tier 1 to Tier 2 after a fixed period of time and again to Tier 3 based on similar time constraints. Globally, policy is additional set for compression, encryption, deduplication, and optimizations and this is applied for content at rest as well as incoming data. Once data has been moved from tier to tier, there is no really process for retrieving that data and promoting it to a different tier based on access or usage patterns.
