摘要： A method and system for service-aware parity placement in a storage system, including after receiving the service notification specifying a target SD: writing a RAID stripe to the persistent storage, where the parity block of the RAID stripe is stored on the target SD and none of the data blocks in the RAID stripe are stored on the target SD. The method further includes performing a modified garbage collection operation that includes identifying a live RAID stripe in the persistent storage, writing a new RAID stripe to a new location in the persistent storage, where the new RAID stripe includes a copy of at least a portion of data from the live RAID stripe and a parity block in the new RAID stripe is stored on the target SD, and issuing a removal notification when the modified garbage collection operation is completed.

摘要： A method for writing data to a storage pool. The method includes receiving a virtual identifier (ID) and an offset for an object, extracting a node identifier (ID) that identifies a first storage server in the storage pool from the virtual ID, obtaining an object layout (OL) for the object from the first storage server, hashing an object ID and an offset ID to obtain a hashed value, where the virtual ID comprises the object ID and where the offset ID is generated from the offset, identifying a second storage server in the storage pool using a global namespace layout (GL), the OL, and the hashed value, and issuing a write request to write data to the object in the second storage server, where the write request comprises the object ID and the offset.

摘要： A PCIe Fabric that includes an IO tier switch, hub tier switches, and a target device connected to one of the hub tier switches. The IO tier switch is configured to receive a TLP from a client, make a determination that an address in the TLP is not associated with any multicast address range in the first IO tier switch and is not associated with any downstream port in the first IO tier switch, and, based on the determinations, route the TLP to the first hub tier switch via a upstream port on the IO tier switch. The hub tier switch is configured to make a determination that the TLP is associated with a multicast group, and, based on the determination, generate a rewritten TLP and route the rewritten TLP to a target device via a downstream port on the hub tier switch.

摘要： A method including intercepting a OFR for a file issued by an application to a FS, forwarding the OFR to the FS, receiving from the FS a FD for the file, issuing a SR for the file to the FS. The further method includes receiving from the FS status information for a target device on which the file is located, where the status information includes an OID for the file, storing a mapping of FD to the OID, intercepting a first FOR for the file, making a determination the that the first FOR is one of a read request and a write request, based on the determination, making another determination that the target device supports the direct I/O protocol, and issuing a DI request to the target device using the OID for the file, where the DI request is not processed by the FS.

摘要： A method for storing data including calculating: a first set of parity values using the data, a second set of parity values using the first set of parity values, and a third set of parity values using the data, and the first set and second set of parity values. The method further includes storing a portion of the data in a grid, where the grid includes grids locations that are each associated with a physical location, where each physical location is determined using a unique combination of at least a first value determined using a first independent fault domain and a second value determined using a second independent fault domain. The method further includes storing parity values from the first set of parity values and parity values from the second set of parity values in the grid, and storing the third set of parity values in an associated parity grid.
