Preserving identities and policies across replication, including: receiving, at a first storage array, a first data frame comprising data associated a dataset stored at the first storage array and an identifier of a quality of service level associated with the first data frame; generating, at the first storage array, a second data frame comprising a portion of the dataset and the identifier of the quality of service level associated with the first data frame; and transmitting the second data frame to a second storage array.

Preserving identities and policies across replication

Applying a rate limit across a plurality of storage systems, including: determining a rate limit for paired storage systems; receiving, by a first storage system, an amount of I/O operations serviced by the second storage system during a previous predetermined period of time; determining whether the amount of I/O operations serviced by the second storage system is less than half of the rate limit for the paired storage systems; if so, setting local a rate limit for a next predetermined period of time for the first storage system to the difference between the rate limit for the paired storage systems and the amount of I/O operations serviced by the second storage system during the previous predetermined period of time; and otherwise, setting a local rate limit for a next predetermined period of time for the first storage system to half of the rate limit for the paired storage systems.
