Autonomic, Real Time Storage Tiering Produces Almost Immediate Gains

Many, if not most, applications today are I/O-constrained, which limits their performance when using traditional HDDs, whether directly attached or in virtualized area networks.  Caching helps improve performance, but fails to scale because it quickly reaches the point of diminishing return on investment.

This Is Where RAID, Inc’s ARI Series Real-Time Tiering Technology Steps In

RAID, Inc.’s ARI Series with tiering technology delivers up to 100,000 random read and 32,000 random write I/Os per second.  The chart below shows the potential performance gains achievable with ARI’s tiered storage. Naturally, the higher the “hit rate” in the SSD tier, the higher the gains.  But even a conservative rate of 70% (easily attainable in most environments) can deliver a 3-times improvement in application performance. Far great performance gains can be realized when the SSD tier handles 80% or more of the I/O load, even though that tier represents only 5-10% of system capacity.

Autonomic, Real Time Storage Tiering Produces Almost Immediate Gains

With autonomic, real-time storage tiering noticeable performance gains are experienced almost immediately, but because performance gains are dependent on the SSD tier hit rate, the tiering’s management system includes an application that enables IT managers to tune the performance.  The application constantly monitors IOps, displays pertinent performance statistics and optionally exports these into .csv files for reporting, archiving and trending analysis needs.
