Abstract
A plurality of failure domains are communicatively coupled to each other via a network, and each of the plurality of failure domains is coupled to one or more storage devices. A failure resilient stripe is distributed across the plurality of storage devices, such that two or more blocks of the failure resilient stripe are located in each failure domain.
Claims20
A system comprising:
- a first storage system;
- a second storage system;
- a first backend;
- and
- a second backend, wherein:
- the first backend and the second backend are operable to reach consensus that the first backend is an active controller,
- if a data access is directed to the second backend, the second backend redirects the data access to the first backend, and
- the first backend is operable to build a failure resilient stripe comprising a first set of blocks located in the first storage system and a second set of blocks located in the second storage system.

A method comprising:
- reaching consensus, between a first backend and a second backend, that the first backend is an active controller;
- if a data access is directed to the second backend, redirecting the data access to the first backend;
- and
- using the first backend to build a failure resilient stripe comprising a first set of blocks located in a first storage system and a second set of blocks located in a second storage system.
