Storage Utilization: Disk Utilization

IT Efficiency Metrics

IT Efficiency Metrics
The clear answer to today’s IT challenges is to increase IT efficiency throughout the infrastructure, from the desktop to the data center. This Wiki is intended to provide a forum where efficiency metrics, goals and guidelines can be shared.

Storage and data management

Metrics concerning the strategy, purchase, deployment, management, and consolidation/virtualization of storage.

Storage Utilization: Disk Utilization

Storage and data management

GOAL OR METRIC: More than 40%

RATIONALE:  The overall cost of storage is expensive and growing. So storing
as much as possible on the fewest number of devices is critical. In a truly efficient data center, storage devices should approach 80% utilization, the point of diminishing returns.  Of course, the only way to reach such high levels of efficiency are through virtualization, standardization of the underlying storage infrastructure, and use of enabling technologies such as iSCSI.

POTENTIAL RESULTS:  Greater utilization mitigates the need for constant purchasing of new hardware.

SIDE NOTES: 

  • The amount of data created and stored digitally is expected to double every 18 months
  • 90% of stored data is never accessed after it is created (IDC. (2010, December).  “Predictions 2011:  Welcome to the New Mainstream.”)

  • "storing as much as possible on the fewest number of devices increases the risk of data loss due to a lack of diversity.  The goal should be about balance and system design life cycles.  Too Much or Too Little of anything is a bad thing.
