Weighted scores are used for read and write operations, since solid state devices operate better with read operations than write operations. The heat index associated with each extent is a function of a base score, rather than an absolute value. The base score is determined by adding the number of extents in a hot tier plus the access score, divided by the number of extents in the hot tier. In this fashion, the base score measures the weighted I/O activity relative to the size of the hot tier."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Relative heat index based hot data determination for block based storage tiering","description":"Disclosed is a process for determining a heat index for a block of data, such as an extent, for storage tiering.
