Systems and methods for scalable storage management

A method is provided for data storage management in a virtualized information handling system that includes a first and second network storage resource, a hypervisor allowing multiple virtual machines to run on the virtualized information handling system, and a data access agent. The data access agent may intercept a data access request initiated by a virtual machine and intended for the first network storage resource. In response to intercepting the data access request, the data access agent may establish a connection with the first network storage resource, and retrieve from the first network storage resource metadata associated with the data access request. The retrieved metadata may identify a location of the second network storage resource. Additionally, the data access may establish a connection with the second network storage resource using the location of the second network storage resource identified by the retrieved metadata. The virtual machine may complete the intercepted data access request via the established connection with the second network storage resource.

A Peripheral Component Interconnect-Express (PCIe) port includes a PCIe link, a pending transaction counter, and an error status register. The PCIe port operates to issue a transaction on the PCIe link, determine that an endpoint device has become uncoupled from the PCIe link after issuing the first transaction, determine that a value stored in the pending transaction counter is not equal to zero in response to determining that the endpoint device has become uncoupled, and set an error bit in the error status register in response to determining that the first value is not equal to zero.

System and method to correlate errors to a specific downstream device in a PCIe switching network

In accordance with the present disclosure, a system and method for transmitting communications over a transmission medium between a first component and a second component is provided. The system and method may include an information handling system in which a packet is defined. The packet may include at least one header at a specific bit location and a vendor defined header extension, located in a packet payload portion of the packet. The system and method may further include at least one control command defined within the information handling system. The at least one control command may, for example, be used to negotiate the meaning of at least one field in the header. In addition, the at least one control command may be used to handle and recover from errors within communications and to control the flow of communications once transmission has commenced.

A method of using an information handling system can include communicating accessibility of a resource to a grid system, powering down the information handling system, receiving a wake request from the grid system, booting the information handling system into a grid mode where the resource is accessible to the grid system. Machine-executable code for an information handling system can include a method for indicating that a resource in the information handling system is accessible to a grid system, communicating that the resource is accessible to the grid system, and placing the information handling system into a low power state. An information handling system can include a processor that can indicate that a resource is accessible to a grid system, communicate to the grid system that the resource is accessible, and place the information handling system into a low power state.

Grid computing resources and a method of use thereof

A method of routing data in an information handling system can include receiving a notification from a management controller at a basic input/output system (BIOS) that includes a system management interrupt (SMI) handler. The a notification can indicate that the management controller has a data packet bound for a peripheral component interconnect express input/output (PCIe I/O) device coupled to a secondary processor. The method can include generating a system management interrupt at the information handling system via the BIOS SMI handler in response to the notification. The method can also include retrieving the data packet from the management controller via the BIOS SMI handler and sending a payload associated with the data packet from the BIOS SMI handler to the PCIe I/O device.

Host-based messaging framework for PCIE device management

For backing up of data from a source to a destination, a virtual tape library (VTL) appliance intercepts a message for backing up the data. In response to the intercepted message, the VTL appliance sends a command to initiate the backing up of the data. A network attached storage (NAS) server, which is the source of the data and is coupled to the VTL appliance by a network, receives the command. An agent located in the NAS server is triggered in response to the command to directly transfer the data from the source to the destination. The agent informs the VTL appliance upon completion of the transfer of the data.

Accelerating NDMP based virtual tape library operations

Virtualization of I/O devices to support operation of plural virtual machines on a host information handling system is managed with distributed translation agents that translate addresses generated from I/O devices according to mapping defined by a virtual machine monitor. The translation agents reside in the host I/O subsystem, such as at I/O hubs or at I/O devices. A discovery module discovers and configures plural translation agents to coordinate I/O device communications with translation of physical memory addresses and virtual I/O addresses.

System and method for distributed address translation in virtualized information handling systems

Redundant storage of information is provided by distributing storage functions between a RAID controller and switching device. The switching device multi-casts writes to storage devices and to the RAID controller. The RAID controller generates parity for the information and writes the parity to the storage devices in space reserved for parity by the switching device. Information is read from the storage devices through the switching device without action by the RAID controller.

System and method for look-aside parity based raid

A method is provided for managing errors in a virtualized information handling system that includes an error detection system and a hypervisor allowing multiple virtual machines to run on the information handling system. The hypervisor may assign at least one memory region to each of multiple virtual machines. The error detection system may detect an error, determine a physical memory address associated with the error, and report that address to the hypervisor. Additionally, the hypervisor may determine whether the memory region assigned to each virtual machine includes the physical memory address associated with the error. The hypervisor may shut down each virtual machine for which a memory region assigned to that virtual machine includes the physical memory address associated with the error, and not shut down each virtual machine for which the memory regions assigned to that virtual machine do not include the physical memory address associated with the error.
