摘要:
Methods and apparatus are provided for virtualizing resources such as host bus adapters connected to a storage area network. Resources are offloaded from individual servers onto a resource virtualization switch. Servers are connected to the resource virtualization switch using an I/O bus connection. Servers are assigned resources such as virtual host bus adapters and share access to physical host bus adapters included in the resource virtualization switch. Redundancy can be provided using multipathing mechanisms.

Methods and apparatus are provided for virtualizing resources including peripheral components and peripheral interfaces. Peripheral component such as hardware accelerators and peripheral interfaces such as port adapters are offloaded from individual servers onto a resource virtualization switch. Multiple servers are connected to the resource virtualization switch over an I/O bus fabric such as PCI Express or PCI-AS. The resource virtualization switch allows efficient access, sharing, management, and allocation of resources.

Provided are systems, methods, and devices for management of storage class memory modules. Methods include receiving a request from an application running on a server, the request received at a memory controller, and maintaining a page table comprising page numbers, server numbers, storage class memory (SCM) dual-inline memory module (DIMM) numbers, and pointers mapping blocks of memory to SCM DIMMs in devices connected to the server through a network interface. The methods also include allocating memory using the request from the application, wherein whether the memory is locally allocated or remotely allocated remains transparent to the application.
摘要:
Methods and apparatus are provided for virtualizing port adapter resources such as network interface cards (NICs) used to connect servers to packet based networks. Resources are offloaded from individual servers onto a resource virtualization switch. Servers connected to the resource virtualization switch using an I/O bus connection share access to NICs. Redundancy can be provided using multipathing mechanisms implemented at individual servers or high availability mechanisms implemented at the resource virtualization switch. Switchover can occur between ports on the same port adapter, between ports on separate adapters, or between ports on separate resource virtualization switches.
摘要:
Methods and apparatus are provided for improving communication between processors in separate computer systems. Components and peripherals in individual computer systems communicate using input/output (I/O) buses such as PCI Express buses. The I/O buses are extended to allow interconnection between computer systems without having to introduce network infrastructure. A transfer controller supporting Direct Memory Access (DMA) is provided to allow even more efficient communication between computer systems.

An apparatus for providing management of uncompensated populations may include processing circuitry. The processing circuitry may be configured to receive patient information corresponding to uncompensated patient treatment events associated with a plurality of patients, apply a screening criteria to identify a patient eligible for care management assignment in which the screening criteria includes qualifications based on uncompensated cost and an identity of a condition for which the patient received treatment, and assign the patient to a selected intervention program based at least in part on the qualifications of the patient.
摘要:
Methods and apparatus are provided for creating a secure zone having multiple servers connected to a resource virtualization switch through I/O bus interfaces, such as PCI Express or PCI-AS. Servers connected to the resource virtualization switch using I/O bus interfaces share access to one or more virtualized cryptographic accelerators associated with the resource virtualization switch. Applications on a server or system images running on hypervisor inside server can use cryptographic accelerators associated with the resource virtualization switch as though the resources were included in the server itself. Connections between multiple servers and the resource virtualization switch are secure non-broadcast connections. Data provided to a resource virtualization switch can be cryptographically processed using one or more shared and virtualized cryptographic accelerators.
摘要:
Methods and apparatus are provided for allowing quality of service (QoS) configuration for storage applications running on servers connected to a storage area network (SAN). Resources such as host bus adapters (HBAs) are offloaded from individual servers onto a resource virtualization switch. Servers are connected to the resource virtualization switch using an I/O bus connection. The resource virtualization switch provides storage applications running on connected servers with different quality of service levels. The resource virtualization switch can also apply traffic shaping policies associated with QoS.
