Data redirector for scale out

Abstract:

Embodiments redirect data from a source to a plurality of deduplication blockpools. In one embodiment, operations include accessing a binary large object (BLOB) that includes a plurality of blocklets, a blocklet having a hash value; upon determining that the plurality of blocklets includes less than a threshold number of blocklets: selecting, according to a first rule set, a target blockpool from among the plurality of deduplication blockpools; upon determining that the plurality of blocklets includes at least the threshold number of blocklets: selecting, according to a second, different rule set, a target blockpool. The second rule set includes a BalanceQuery rule that computes a fitness value for a member of the plurality of deduplication blockpools, and selects a target blockpool based, at least in part, on the fitness value. Embodiments provide the BLOB to the target blockpool.
