  • Patent number: 8352586
    Abstract: A storage area network (SAN) includes a management server, a storage device, and a management station coupled to a fabric. The management server implements device domains on the SAN. The storage device instructs the management server to add new device domains on the SAN. The management station defines the new device domains to include the storage device and an initiator coupled to the fabric, and directs the storage device to instruct the management server to add the new device domains. A method includes coupling a management server to a SAN fabric, implementing device domains in the management server, defining a new device domain that includes a storage device and an initiator coupled to the SAN, and coupling a storage device to the SAN fabric, the storage device being operable to instruct the management server to add the new device domain.

  • Publication number: 20130007852
    Abstract: Access to backup information, such as at network attached storage compliant with NDMP, is managed by interfacing a backup authentication mechanism with a primary authentication system and responding to requests for backup information according to permissions defined by the primary authentication system. A data management application requests access to backup information with an NDMP MD5 hash and includes a domain name and password for an LDAP or AD authentication through a pluggable authentication module. Access to backup information is provided based upon the permissions associated with the domain of the primary authentication mechanism.

  • Patent number: 8321522
    Abstract: Systems and methods for reducing latency on a remotely-booted information handling system are disclosed. A method for access and management of remote data may include receiving from a host a standard input-output instruction including a persistent image update (PIU) parameter indicating a request by the host to access a shared computer-readable medium storing an image shared by the host and one or more other hosts. The method may further include determining a value of the PIU parameter and determining whether to allow the host to access the shared computer readable medium based at least on the value of the PIU parameter.

  • Publication number: 20120166750
    Abstract: A method of managing storage device resets in a system using shared storage is provided. A reset instruction is received at a shared storage device from a first node. In response, the storage device is at least partially reset, including aborting one or more queued I/O commands including a first I/O command received from a second node. A reset notification timer is started. If an I/O command is received from the second node during the reset notification timer, in response to receiving the I/O command the second node is notified of the storage device reset such that the second node can determine that the first I/O command was aborted. If no I/O command is received from the second node during the reset notification timer, at the expiration of the timer, the second node is notified of the storage device reset such that the second node can determine that the first I/O command was aborted.

  • Publication number: 20120102291
    Abstract: A system includes a host processing system that launches virtual machines, a switched fabric, a storage area network that provides storage capabilities to the virtual machines, and a virtualized cloud environment manager that receives workload service profiles. The manager includes a virtual machine allocation framework that directs the host to launch a virtual machine in response to receiving a service profile, a network allocation framework that directs the fabric to provide network connectivity to the virtual machine in response to receiving the service profile, and a storage allocation framework with a workload interface that receives a workload storage requirement from the service profile, a storage capabilities database that determines capabilities of the network, and a storage manager that determines a storage allocation from the capabilities and allocates storage to the workload.

  • Publication number: 20120079220
    Abstract: A spilt backup agent model where a component on a host and a component on the block storage device function together logically to provide a backup agent. In certain embodiments, the mechanism provides a split backup agent model using a NDMP protocol. The NDMP protocol is an industry standard protocol that allows for backup of hosts with a single backup agent that is compatible with multiple independent software vendor (ISV) backup software. Thus with the present invention, proprietary backup software dependent host agents are not required. The NDMP protocol provides for separation of control and data connections where the control path runs between the data server on the host that needs to be backed up and backup software (e.g., a Data Management Application (DMA)) and between the backup device and the backup software. The data path runs between the host and the backup device.

  • Patent number: 8037523
    Abstract: A method for single sign-one for operating system (OS) boot image provisioning and OS login based on user identity includes receiving authentication information from an information handling system (IHS) over a network. The authentication information is associated with a user. The authentication information is sent to network services. Boot image information is received from the network services. The boot image information is associated with a boot image and the authentication information. The boot image is provisioned to the IHS over the network, wherein the boot image includes an OS that is configured to read the authentication information from a shared memory region of the IHS and use the authentication information to auto-login the user to the OS.

  • Publication number: 20110176551
    Abstract: Information handling system network traffic is managed by populating a DCBX client framework with application network parameters associated with predetermined applications. Network devices, such as information handling system clients and servers, retrieve a TLV from a switch to obtain application network parameters for an application and apply the parameters so that the application executing on the device tags network communications with the associated parameters, such as bandwidth, loss less behavior, priority, latency, through put and CPU utilization.
