The multi-instance database may then be deployed and data may be loaded in parallel for the instances.
Logical block protection for tape interchange
Granted: August 9, 2016
Patent Number:
9412412
A two part process is used for modifying records to be written and retrieved from tape devices. A record is appended with a cyclic redundancy check and a string of zeros. Submitting the entire record to tape drives which are logical block protection enabled will result in no change. For drives that are not LBP enabled, the string of zeros at the end of the record is removed. In addition to determining whether a drive is LBP compliant, a determination may be made as to whether a drive is…

Real-time storage area network
Granted: July 5, 2016
Patent Number:
9386100
A cluster of computing systems is provided with guaranteed real-time access to data storage in a storage area network. Processes issue request for bandwidth reservation which are initially handled by a daemon on the same node as the requesting processes. The local daemon determines whether bandwidth is available and, if so, reserves the bandwidth in common hardware on the local node, then forwards requests for shared resources to a master daemon for the cluster. The master daemon makes…
System and method for removing data from processor caches in a distributed multi-processor computer system
Granted: June 14, 2016
Patent Number:
9367473
A processor (600) in a distributed shared memory multi-processor computer system (10) may initiate a flush request to remove data from its cache. A processor interface (24) receives the flush request and performs a snoop operation to determine whether the data is maintained in a one of the local processors (601) and whether the data has been modified. If the data is maintained locally and it has been modified, the processor interface (24) initiates removal of the data from the cache of…
Network filesystem asynchronous I/O scheduling
Granted: June 7, 2016
Patent Number:
9361474
Resource acquisition requests for a filesystem are executed under user configurable metering. Initially, a system administrator sets a ratio of N:M for executing N read requests for M write requests. As resource acquisition requests are received by a filesystem server, the resource acquisition requests are sorted into queues, e.g., where read and write requests have at least one queue for each type, plus a separate queue for metadata requests as they are executed ahead of any waiting…
Relocation of metadata server with outstanding DMAPI requests
Granted: March 1, 2016
Patent Number:
9275058
A cluster of computer system nodes share direct read/write access to storage devices via a storage area network using a cluster filesystem and operating system implementing DMAPI. Threads executing on a metadata client know when a DMAPI event is required, and generate the DMAPI event on their own initiative when necessary. A metadata server maintains DMAPI queues. If the metadata server relocates to another host, the DMAPI events in the DMAPI queues are moved transparently to users.
