A system and method for client and network based erasure code recovery. In some embodiments, the method includes: receiving, by a storage node, a get command; storing, by the storage node, in a memory of a host, using remote direct memory access, data specified by the get command, at a memory address specified by the get command; sending, by the storage node, a response, indicating successful execution of the get command; and performing, by the host, erasure code recovery based on the data.

Client and network based erasure code recovery

A method may include receiving, at a target, from a server, a command, information to identify data, and access information to perform a data transfer using a memory access protocol, and performing, based on the command, based on the access information, the data transfer between the target and a client using the memory access protocol. The information to identify the data may include an object key, and the object key and the access information may be encoded, at least partially, in an encoded object key. The method may further include sending, based on the data transfer, from the target to the server, a completion. The method may further include sending, based on the completion, from the server to the client, an indication of success. The method may further include reconstructing the data based on the parity data.

A memory appliance (MA) comprising a plurality of memory modules is configured to store data within the plurality of memory modules and further configured to receive data commands from first server and a second server coupled to the MA. The data commands may include direction memory access commands such that the MA can service the data commands while bypassing a host controller of the MA.

A solid state device (SSD) write operation management system including a file system that incorporates SSD status information into its operational logic is disclosed. By incorporating SSD status information, the system achieves various advantages over conventional systems, such as enhanced write performance and extended SSD lifespan. The system processes various criteria to select the optimal virtual device ('vdev') for data allocation in response to a write request. The first criterion utilizes Program/Erase counts of physical blocks contained in the SSDs. Another criterion is the number of physical free blocks of a drive. If the average of the selected vdev's physical free blocks is higher than the OP threshold, then the system selects for data allocation the vdev with the greatest amount of logical free space. In the instance that the average is lower, the system schedules garbage collection for the vdev.

Also described are related methods for performing data management operations in a file system-aware manner. By incorporating both file system and physical storage information, the system may achieve various advantages over conventional systems, such as enhanced I/O performance, simplified SSD firmware, and extended SSD lifespan. Moreover, by moving solid-state management functions above the firmware level, the system may enable the simultaneous management of a pool of multiple SSDs.
