Policy! Policy!! Policy!!!

It has been an exciting month, some new details are emerging related to automated storage tiering, workload distributions, workflow automation, SLA’s, QoS and how Policy based storage management can help solve these challenges. “Policy” as we all know in the “business world”, “advanced algorithms” as known in “scientific community” is used to solve complex storage challenges. This has been one of the favorite topics of discussion in the storage blogosphere these days.

Though there are two distinct groups of people, one favoring automation and the other half possibly thinking this technology brings no value-add in terms of how storage is utilized and managed today. This game was initially started by Compellent (Compellent Data Progression technology) about 4 years ago, then joined by Pillar Data Systems and now other OEM’s (including EMC, HDS, IBM) are starting to catchup on policy based automated storage tiering.

With private clouds in the near future and then hybrid clouds (a mesh of private and public clouds) in the horizon, automation, workload distribution, SLA’s, QoS will need to be monitored and managed to optimally run IT Infrastructures. Policy based management will create a new wave of storage management, automation and will act as a principle ingredient of hybrid clouds.

Generation 1 of policy based storage tiering works within a single storage subsystem.
Generation 2 in the near future should work across heterogeneous storage subsystems (by the same manufacturers).
Generation 3 over the next year or two will work across storage platforms irrelevant of the manufacturers.
Generation 3 of policy based management will include the entire stack of management. These products will be capable of not only managing the Storage, but also interact through policies at the Virtualization, Networking, Application, OS, Middleware and other layers in the stack of Infrastructure management..

We should see an up-rise of new emerging technologies that will create these external policy based engines for data movement automation. All infrastructure components including Storage, Virtualization, Networking, Application, OS, Middleware will provide the necessary API’s for these external engines to interact and enable data automation and workflow automation in hybrid clouds (irrelevant of the manufacturers).
