  • Publication number: 20140258537
    Abstract: A method for storage management in a storage system, such as a storage area network (SAN). A selection of a first target level of storage service quality (e.g., bronze, silver, gold, platinum) for a storage repository to be created in the SAN is received. The first target level of storage service quality represents a level of storage service quality for the storage repository along a first dimension (e.g. performance, availability) of storage service quality. A first set of storage configuration properties associated with the first level of desired storage service quality is determined. One or more storage components of the SAN are allocated to the storage repository based on at least one storage configuration property in the first set of storage configuration properties.

  • Patent number: 8743872
    Abstract: A plurality of SMP modules and an IOP module communicate storage traffic via respective corresponding I/O controllers coupled to respective physical ports of a switch fabric by addressing cells to physical port addresses corresponding to the physical ports. One of the SMPs executes initiator software to partially manage the storage traffic and the IOP executes target software to partially manage the storage traffic. Storage controllers are coupled to the IOP, enabling communication with storage devices, such as disk drives, tape drives, and/or networks of same. Respective network identification registers are included in each of the I/O controller corresponding to the SMP executing the initiator software and the I/O controller corresponding to the IOP. Transport of the storage traffic in accordance with a particular VLAN is enabled by writing a same particular value into each of the network identification registers.

  • Patent number: 8713295
    Abstract: A Cost-Reduced Enterprise Server (CRES) system includes a flexible resource-efficient server having a plurality of Processor Memory Boards (PMBs) coupled to an Input/Output Module (IOM). The IOM provides all networking and storage interfaces for the server. The IOM is implemented as a field-replaceable pluggable module, and thus all Input/Output (I/O) capabilities or resources of a CRES system may be upgraded via replacement of the IOM. Each PMB is dividable into a pair of Symmetric MultiProcessor (SMP) complexes, and each complex is coupled to a respective portion of the I/O resources provided by the IOM. Each portion of the IOM provides a pair of I/O daughter-module connectors compatible with standard I/O interfaces, such as Peripheral Component Interconnect (PCI)-X and PCI-Express. One or more CRES systems may be coupled to one or more Enterprise Server (ES) systems to form a multi-chassis server managed collectively as one or more provisioned servers.

  • Patent number: 8601053
    Abstract: Multi-chassis fabric-backplane enterprise servers include a plurality of chassis managed collectively to form one or more provisioned servers. A central client coordinates gathering of provisioning and management information from the chassis, and arranges for distribution of control information to the chassis. One of the chassis may perform as a host or proxy with respect to information and control communication between the client and the chassis. Server provisioning and management information and commands move throughout the chassis via an Open Shortest Path First (OSPF) protocol. Alternatively, the client may establish individual communication with a subset of the chassis, and directly communicate with chassis in the subset. Server provisioning and management information includes events generated when module status changes, such as when a module is inserted and becomes available, and when a module fails and is no longer available.

  • Patent number: 8489754
    Abstract: An optimized spanning tree protocol (OSTP) minimizes latency and provides high throughput in a full-mesh portion of a network, and is compatible with external networks where a standard spanning tree protocol is used. The OSTP enables traffic traversing the full-mesh portion to take a shortest path from source to destination through use of full-mesh connectivity. In some embodiments, a cluster includes a plurality of servers connected in a full mesh, and the OSTP is used on internal ports of the servers. In some embodiments, the OSTP is configured on a per-VLAN basis. In some embodiments, the servers exchange special messages enabling determination of full-mesh connectivity. In further embodiments, sending of the special messages is suppressed on certain port types, such as external ports. In some embodiments, determination of the full-mesh connectivity disables use of a standard spanning tree protocol and/or enables use of OSTP on the full-mesh portion.

  • Patent number: 8301749
    Abstract: Real time provisioning and management of fabric-backplane enterprise servers includes monitoring system status and configuration, displaying monitoring results, accepting user commands, and providing hardware and software management and configuration commands to the system. In one embodiment, an event is generated when a pluggable module is inserted into the system. In response to the event, the availability of the pluggable module is displayed to a system operator, and the operator enters a command to provision a server that includes the pluggable module. The server provisioning command is processed, resulting in a hardware configuration command being issued to the system, and an event indicating a status associated with processing the command is returned. The recognition of the inserted module, the display to the operator, and the processing of the server provisioning command occur in real time.
