Will auto-tiering solve your virtualization challenges?

 

Automated storage tiering allows virtualized environments to rapidly adapt to fluctuations in VM storage activity.  The ability to move data among storage drives depending on speed and space requirements of your data can help with accessibility.  Yet, while auto-tiering solves accessibility at the array level, it cannot assure performance nor efficiency at the hypervisor layer. Managing datastore congestion and availability remains unsolved.  So how can you maximize your company’s investment into your ATS environment?

On a recent discussion with a law firm last week, the director of IT highlighted the recent implementation of an auto-tiering system from Compellent Technologies (Dell).  He created different classes of service based off the underlying drives.  Allowing for high IOPS consumers to sit on faster drives while historical documents, notices, and smaller VMs could be placed on their extensive SATA environment.  Despite such advancements in the array layer, they had difficulty managing their database’s high usage/thin provision risk alongside their less “hungry” legal documentation files/VMs.  As was the case, I explained how VMTurbo can perfectly compliment their storage architecture.

In order to solve thin provision risk on the datastores in an auto-tiered environment, our system views datastores as both a consumer and provider of resources.  Let’s look at managing thin provision risk using this resource relationship model.
