A block from a Flash Pool read operation is initially marked as __________.

Hot status is reserved for blocks with a demonstrated high-frequency access pattern, not for newly inserted blocks with no access history.

Warm indicates a moderate level of re-access activity and is an intermediate state achieved after the initial neutral classification.

Flash Pool uses a temperature-based caching policy to manage which blocks reside in the SSD tier. A block newly inserted into the cache from a read operation receives a neutral classification because there is no prior access history to evaluate. Subsequent re-access promotes the block toward warm or hot status, while lack of re-access allows it to age toward cold, making it eligible for eviction.

Cold indicates a block has not been recently accessed and is a candidate for eviction - the opposite state of a freshly inserted block.

Evict is not a temperature marking but rather an action taken on cold blocks to remove them from the SSD cache tier.
