    摘要: Methods and systems for improved access to storage resources include installing a virtual storage appliance as a virtual machine on a hypervisor. The virtual storage appliance installs itself as a virtual PCI-E device and communicates with guest operating systems of the hypervisor using direct memory access via a PCI-E non-transparent bridge. The storage virtual appliance provides access to local and external storage resources with very high performance to applications running under the guest operating system, thereby overcoming performance barriers associated with native hypervisor driver models.

    摘要: Methods and systems for I/O acceleration on a virtualized information handling system include loading a storage virtual appliance as a virtual machine on a hypervisor. The hypervisor may execute using a first processor and a second processor. The storage virtual appliance is accessed by the hypervisor using a PCI-E device driver that is mapped to a first PCI-E NTB logical endpoint at the first processor. A second PCI-E device driver may be loaded on the storage virtual appliance that accesses the hypervisor and is mapped to a second PCI-E NTB logical endpoint at the second processor. A data transfer operation may be executed between a first memory space that is mapped to the first PCI-E NTB logical endpoint and a second memory space that is mapped to the second PCI-E NTB logical endpoint. The data transfer operation may be a read or a write operation.
