  • System, Method and Computer-Readable Medium for Dynamically Configuring an Operational Mode in a Storage Controller
    Publication number: 20150286438
    Abstract: A storage controller coupled to a host computer is dynamically configured by a device driver executing in the host computer. The storage controller manages a logical volume for the host using a set of flash-based storage devices arranged as a redundant array of inexpensive disks (RAID). The device driver identifies a RAID type for the logical volume and a queue depth from a stream of I/O commands. For a logical volume in RAID 0, the device driver compares the queue depth to a threshold value and configures the storage controller to process the stream of I/O commands with a first path or an alternative path based on a result of the comparison. For a logical volume in RAID 5, the device driver performs a similar comparison and uses the result to direct the storage controller to use a write back or a write through mode of operation.

  • DEVICE ABSTRACTED ZONE MANAGEMENT OF SERIAL ATTACHED SMALL COMPUTER SYSTEM INTERFACE TOPOLOGIES
    Publication number: 20150286604
    Abstract: Systems and methods provide zone management for devices in a Serial Attached Small Computer System Interface (SAS) topology. In one embodiment, a zone management device stores a zone map that identifies an initial zone of a device in the topology. The management device detects changes in the topology, and identifies a current zone of the device subsequent to the change in the topology. The management device compares the zone map for the device to the current zone to identify a change in the zone of the device, and generates a message for an expander in the topology based on the change in the zone. The management device then transmits the message to the expander to restore the zone of the device to the initial zone.
