Abstract: Disclosed are systems, computer-readable mediums, and methods for receiving an input/output operation regarding data associated with a distributed storage system that includes a plurality of storage devices. A key identifier associated with the I/O operation is determined. The key identifier identifies a key that has been divided into a number of key pieces. Two or more storage devices of the plurality of storage devices that contain one or more of the key pieces are determined and at least a threshold number of key pieces are requested from the two or more storage devices. The minimum number of key pieces needed to reconstruct the key is the threshold number. The key is reconstructed from the requested key pieces. A cryptographic function is performed on data associated with the I/O operation using the reconstructed key and the I/O operation is completed based upon the performed cryptographic function.

Abstract: Disclosed are systems, computer-readable mediums, and methods for reading a sequence number from regions of a solid state storage device. A latest region is determined based upon the sequence numbers and a checkpoint file is read within the latest region. A request for a block of data of a first branch is received. A first block of pointers associated with the first branch from the checkpoint file is read. A first pointer from the first block of pointers and a second block of pointers pointed to by the first pointer are read. A second pointer from the second block of pointers and a third block of pointers pointed to by the second pointer are read. A third pointer from the third block of pointers and data pointed to by the third pointer are read. The block of data of the first branch is determined based upon the read data. The block of data is returned.

Abstract: Disclosed are systems, computer-readable mediums, and methods for receiving a start replication message to replicate a source volume to a replicated volume. A source system forwards I/O requests to the replica server. A data structure associated with the replicated volume is initialized. A write request is received from the source system. The write data is written to the replicated volume and the data structure is updated. Source metadata associated with the source volume is received. The source metadata is compared with prior metadata associated with a prior point-in-time image of the source volume to determine blocks of data that have changed since the prior point-in-time image of the source volume. A first block is determined to not be retrieved based upon the data structure. A second block is determined to be retrieved based upon the data structure. The second block is received and written to the replicated volume.

Abstract: Disclosed are systems, computer-readable mediums, and methods for incremental block level backup. An initial backup of a volume is created at a backup server, where creating the initial backup includes retrieving an original metadata file from a metadata server, and retrieving a copy of all data of the volume based on the original metadata file. A first incremental backup of the volume is then created at the backup server, where creating the first incremental backup includes retrieving a first metadata file, where the first metadata file was created separately from the original metadata file. A block identifier of the first metadata file is compared to a corresponding block identifier of the original metadata file to determine a difference between the first and original block identifiers, and a copy of a changed data block of the volume is retrieved based on the comparison of the first and original block identifiers.

Abstract: Disclosed are systems, computer-readable mediums, and methods for determining client metrics of a volume in a storage system for a first client of a plurality of clients. The storage system stores data from the plurality of clients. System metrics of a cluster in the storage system are determined based upon use of the storage system by the plurality of clients. A load value of the storage system is determined based upon the system metrics and the client metrics. The load value is determined to be above a predefined threshold. A target performance value is calculated based upon the load value, a minimum quality of service value, and a maximum quality of service value. Performance of the storage system is adjusted for the client based upon the target performance value and the determining the load value is above the predefined threshold.

Abstract: Disclosed are systems, computer-readable mediums, and methods for efficiency sets in a distributed system. A first efficiency set is determined for a first volume of data. Determining the first efficiency set includes selecting block identifiers for data blocks of the first volume, where each block identifier is used to access a particular data block corresponding to the first volume. Determining the first efficiency set further includes applying a mask to the selected block identifiers to mask at least one bit of each selected block identifier. The first efficiency set is compared to a second efficiency set for a second data store, and based on the comparison, an amount of unique data blocks of the first volume is approximated.

Abstract: Methods, systems, and apparatuses, including computer programs encoded on computer-readable media are disclosed for binding a process to a wildcard address and a port on a plurality of nodes of a cluster. A process receives a first request for a first address of a first volume that is sent to the port and a first address associated with a first virtual local area network that is not the wildcard address. The process determines the first address, a name of the first VLAN, and a first node that contains information regarding the first volume. The process determines an address of the first node that is part of the first VLAN. The address of the first node is returned. The process receives another request for a second address of a second volume that is sent to the port and a second address associated with another VLAN that is not the wildcard address.
