Abstract
In a multi-tiered system, read temperature and write temperature per virtual block (VLB) can be determined based on the content referenced by each VLB. The read temperature can describe VLB read activity relative to the recency and frequency of read misses of content referenced by the VLB. The write temperature can describe VLB write activity relative to the recency and frequency of overwrites with respect to content referenced by the VLB. Read misses and overwrites can be recorded per processing core in an active tablet used for recording by only a single core. Active and analytic tablet sets across cores can be switched based on criteria. Analytic tablets can be processed and used to update metrics, including read and write temperatures, stored for VLBs. The metrics can be used to determine temperature classifications of VLBs. Content referenced by VLBs can be promoted and/or demoted using VLB temperature classifications.
