Automated storage tiering: Higher performance AND lower cost?
This article is part of the Vol. 10 Num. 3 May 2011 issue of Storage magazine
Remember those light beer commercials back in the 1980s with competing contingents shouting “Tastes great!” and “Less filling!” at each other? The idea was that a beer could have fewer calories without sacrificing taste. Perhaps advocates of automated storage tiering (AST) are taking a similar approach: its two goals -- lower cost and higher performance -- seem to be just as diametrically opposed. Historically, if you wanted higher I/O performance (data throughput) you bought high-end Fibre Channel (FC) arrays and disk devices. If budget was a bigger issue, you gravitated toward IP storage and SATA drives. In practice, most companies use both types of storage in an effort to match application throughput requirements with budget constraints. That effectively represents tiered storage, and how that tiering is managed boils down to whether the staff chooses de facto manual tiering or implements an automated system. Given the increasing complexity of data storage environments, data growth and the typically poor utilization of ...

Data storage budgets are recovering from their recessionary pounding. But while storage managers might have more money to spend, they’ll need yet more capacity to meet new demands.
Cloud storage and computing services offer a number of alternatives for cloud-based DR depending on the recovery time and recovery point objectives a company requires.
In our most recent Snapshot survey, we asked respondents why they were archiving: 28% say they’re doing it for legal issues, while 26% use it for capacity management.
Automated storage tiering is an effective way to make efficient use of installed data storage resources, and to take advantage of the high performance of solid-state storage.

As file data growth surges, traditional backup just won’t cut it anymore; we need some new thinking and an updated approach to replication.
Buzzwords are taking over the data storage industry, so it’s probably asking way too much of storage vendors to just tell us what their products can -- and can’t -- do.
Unified storage adoption is starting to ramp up as data storage pros see the need for simplifying storage so it can be powered, cooled and managed in one pool.
Break down the cloud storage services market and you’ll find players both big and small jockeying for position in key segments.
