Auto Tiering (QTiering)
QSAN Auto Tiering (QTiering) cost-effectively and dynamically places hot data on SSD or faster hard drives and cold data on lower cost high-capacity drives, allowing you to optimize application performance without straining your budget or sacrificing capacity.
Our QTiering algorithm uses intelligent data analysis that continuously monitors data usage and ranks this data based on how often it is accessed. It will then use this information and make a decision on where your data should be.
Our intuitive SANOS 4.0 web UI interactively shows the data being gathered; how this data is being used, and how much of each tier storage should be assigned based on this information. Then at the scheduled time, the most accessed blocks that have been marked as “hot” data will be migrated into the highest performing tier, the least accessed or “cold” data will be migrated into the lowest cost - highest capacity drive tier.
