US 10,764,389 B2 · Managing replica caching in a distributed storage system

Abstract

Technologies for managing replica caching in a distributed storage system include a storage manager device. The storage manager device is configured to receive a data write request to store replicas of data. Additionally, the storage manager device is configured to designate one of the replicas as a primary replica, select a first storage node to store the primary replica of the data in a cache storage and at least a second storage node to store a non-primary replica of the data in a non-cache storage. The storage manager device is further configured to include a hint in a first replication request to the first storage node that the data is to be stored in the cache storage of the first storage node as the primary replica. Further, the storage manager device is configured to transmit replication requests to the respective storage nodes. Other embodiments are described and claimed.

Dependent claims

A storage node comprising:

a cache storage;
a non-cache storage;
one or more processors;
and
one or more memory devices having stored therein a plurality of instructions that, when executed by the one or more processors, cause the storage node to:
receive a replication request to store data in the storage node;
determine whether the replication request includes a hint indicative of an instruction to store the data as a primary replica in the cache storage;
select one of the cache storage or the non-cache storage to store the data in based on the determination of whether the replication request includes the hint;
and
store the data in the selected one of the cache storage or the non-cache storage.
