Some embodiments provide a method that, at a first machine that operates at a first physical site as a primary global manager for a logical network spanning a plurality of physical sites, receives a set of ordered data describing a configuration of the logical network. The method stores, in a particular order, the received set of ordered data in a first database located at the first physical site. Through a channel between (i) the first machine and (ii) a second machine that operates at a second physical site as a secondary global manager for the logical network in case of failure of the primary global manager, the method provides the set of ordered data in the particular order for the second machine to store in a second database in the particular order. The second database located at the second physical site.

Replication of logical network data between global managers

A key-value store supporting GET, PUT and DELETE operations, serializes multiple clients using two locks, and that supports asynchronous resizing. The locking scheme includes an operation of holding two locks, one for the key involved in the operation, one for the page currently searched or updated. The store can either be a single volume holding keys and data or can be organized as a directory volume referencing a number of data volumes organized by data-size ranges. The scheme also supports asynchronous resizing of the directory while continuing to perform operations.
