摘要： A network storage appliance includes a chassis, enclosing a storage controller and first and second servers. The storage controller has first and second I/O ports for coupling to first and second I/O links. The storage controller controls a plurality of physical disk drives and presents the plurality of physical disk drives as one or more logical disk drives on the first and second I/O links. The servers each have an I/O port for coupling to a respective one of the first and second I/O links. Each of the servers transmits packets to the storage controller over the respective I/O link. The packets include block-level protocol disk commands each identifying one of the logical disk drives, such as SCSI block level protocol commands each identifying one of said logical disk drives as a SCSI logical unit. The I/O links may be FibreChannel, Ethernet, or Infiniband links, for example.

摘要： A network storage appliance integrates a plurality of servers and a plurality of storage controllers into a single chassis. The storage controllers control transfers of data between the servers and storage devices controlled by the storage controllers. The servers and storage controllers comprise a plurality of field replaceable units (FRUs) that plug into a backplane also enclosed in the chassis. The FRUs are redundant such that any one of the FRUs may fail without incurring loss of availability of the data stored on the storage devices. One of the storage controllers detects a failure of one of the servers and responsively kills the failed server. The failure may be a stopped heartbeat from the failed server. Additionally, one of the storage controllers detects a failure of a heartbeat link coupling the servers and responsively inactivates one of the servers to enable failover to the live server.

摘要： An apparatus and method for deterministically killing one of redundant servers on a common network is disclosed. The apparatus includes a chassis that encloses the servers and a storage controller, status indicators generated by the servers to the storage controller, and kill controls, generated by the storage controller to respective ones of the servers, each for killing a respective one of the servers. The status indicators and kill controls are wholly enclosed in the chassis. The kill controls deterministically disable the killed server on the network independently of the state of the server to be killed. That is, the server does not need to be able to respond to a command to be disabled on the network. In one embodiment, the kill controls comprise reset signals. After the storage controller deterministically kills one of the servers, the other server takes over the identity of the killed server on the network.

摘要： The verification of fault-tolerant connections between redundant controller pairs and nodes is provided. In particular, a node identifier seen at one port of the controllers is compared to the node identifier seen at another port of the controllers. In response to determining that proper connections have not been made, an error or warning signal may be generated. In addition, where supported by dynamic port configuration, the ports of the controllers may be reconfigured in response to the comparison to effect proper connections. In response to determining that proper connections have been made, a signal verifying that proper connections have been made may be generated.

摘要： A network storage appliance including one or more integrated switching devices is disclosed. The appliance includes redundant storage controllers that transfer frames of data between storage devices and host computers. The integrated switching devices include a plurality of I/O ports and a data transfer path between each of the I/O ports for providing simultaneous data transfers between multiple pairs thereof. The switches enable the appliance to simultaneously transfer frames between its I/O ports and storage device I/O ports and/or host I/O ports, thereby providing increased data transfer bandwidth over arbitrated loop configurations. Additionally, the switches are intelligent and may be programmed to achieve improved fault isolation. The appliance may also include servers that include I/O ports coupled to the switches for simultaneously transferring data with the storage controllers and/or I/O ports of devices external to the appliance.

摘要： A SAS expander includes SAS PHYs for transceiving signals with SAS devices on corresponding SAS links coupled to the SAS PHYs. The SAS expander includes status registers that provide fault detection parameters concerning communications on the SAS links. A microprocessor of the SAS expander identifies faulty communications on one of the SAS links, based on the fault detection parameters, and disables a corresponding one of the SAS PHYs coupled to the SAS link on which the microprocessor identified the faulty communications. The microprocessor may also report the PHY disabling to a SAS initiator. The microprocessor may also re-enable the PHY after corrective action is taken, such as in response to user input, an indication from a SAS device, or automatically detecting the corrective action. The expander may also automatically take the corrective action. The fault detection parameters may include error counters and corresponding thresholds, interrupt indicators, and state values.
