Supporting multiple replication schemes across distinct network layers, including: replicating, over a first type of network messaging layer, data between a first storage system and a second storage system; selecting a different messaging layer for data replication; and replicating, over a second type of network messaging layer, data between the first storage system and the second storage system.

Switching between network layers for replication

Replicating a dataset in a storage system operating in a reduced power mode, including: detecting that the storage system should enter the reduced power mode; entering the reduced power mode; and performing, while in the reduced power mode, one or more data replication operations associated with the dataset, including selecting, from amongst a plurality of data communication mechanisms, a data communication mechanism to utilize for performing the one or more data replication operations.

Replicating data in a storage system operating in a reduced power mode

Selective communication protocol layering for synchronous replication, including: initiating, by a first storage system issuing a command in accordance with a first communication protocol, a connection specifying the first storage system to be a target of storage content from a second storage system; receiving, from the second storage system by the first storage system, a connection request in accordance with the first communication protocol, wherein the connection request specifies the first storage system to be a source of storage content to the second storage system; and based on both initiating the connection and receiving the connection request in accordance with the first communication protocol: establishing, by the first storage system and in accordance with a second communication protocol, both a connection for receiving storage content from the second storage system and a connection for sending storage content to the second storage system.

Supporting multiple replication schemes across distinct network layers

Continuing replication during storage system transportation, including: replicating, between a first storage system and a second storage system, a dataset; connecting, by the first storage system during movement of the first storage system to a new physical location, to a communication network available at one or more intermediate physical locations; and continuing the replicating of the dataset between the first storage system at one or more of the intermediate physical locations and the second storage system over the communication network available at one or more of the intermediate physical locations.

Continuing replication during storage system transportation

Replication handling during storage system transportation, including: replicating, between a first storage system and a second storage system that are both located at a first physical location, a dataset; connecting, by the first storage system and responsive to movement of the first storage system to an intermediate physical location, to a communication network available at the intermediate physical location; and continuing, between the first storage system at the intermediate physical location and the second storage system at the first physical location, replication of the dataset over the communication network available at the intermediate physical location.

Replication handling during storage system transportation

Replication handling among distinct network transfer layers, including: establishing, over a first type of network messaging layer, a communication link for replication between a first storage system and a second storage system; initiating, over a second type of network messaging layer, a configuration change to one or more aspects of the first storage system; and replicating, without disrupting the configuration change to the one or more aspects of the first storage system, data from the first storage system to the second storage system.

Replication handling among distinct networks

Aspects of dynamic data compression selection are presented. In an example method, as uncompressed data chunks of a data stream are compressed, at least one performance factor affecting selection of one of multiple compression algorithms for the uncompressed data chunks of the data stream may be determined. Each of the multiple compression algorithms may facilitate a different expected compression ratio. One of the multiple compression algorithms may be selected separately for each uncompressed data chunk of the data stream based on the at least one performance factor. Each uncompressed data chunk may be compressed using the selected one of the multiple compression algorithms for the uncompressed data chunk.
