Abstract:
A method, non-transitory computer readable medium, and device that assists with reducing memory fragmentation in solid state devices includes identifying an allocation area within an address range to write data from a cache. Next, the identified allocation area is determined for including previously stored data. The previously stored data is read from the identified allocation area when it is determined that the identified allocation area comprises previously stored data. Next, both the write data from the cache and the read previously stored data are written back into the identified allocation area sequentially through the address range.
Abstract:
The disclosed embodiments relate to systems and methods for coordinating management of a shared disk storage between nodes. Particularly, a messaging protocol may be used to communicate notifications regarding each node's perception of the shared storage's state. The nodes may use the messaging protocol to achieve consensus when recovering from a storage device failure. Some embodiments provide for recovery when localized failures, such as failures at an adapter on a node, occur.
