摘要

An apparatus in one embodiment comprises a host device comprising a processor coupled to memory. The host device is configured to communicate over a network with at least one storage system. The host device is further configured to generate a user space block device and to generate a kernel space block device corresponding to the user space block device. The host device is further configured to receive an input-output operation at the kernel space block device from an application executing on the host device and to transfer the input-output operation from the kernel space block device to the corresponding user space block device. The host device is further configured to submit the input-output operation to the at least one storage system based at least in part on the user space block device.

說明書

Also included in the processing device is network interface circuitry, which is used to interface the processing device with the network and other system components, and may comprise conventional transceivers.

As another example, portions of a given processing platform in some embodiments can comprise converged infrastructure such as VxRail?, VxRack?, VxRack? FLEX, VxBlock?, or Vblock? converged infrastructure from VCE, the Virtual Computing Environment Company, now the Converged Platform and Solutions Division of Dell EMC.

Again, these particular processing platforms are presented by way of example only, and other embodiments may include additional or alternative processing platforms, as well as numerous distinct processing platforms in any combination, with each such platform comprising one or more computers, servers, storage devices or other processing devices.

It should therefore be understood that in other embodiments different arrangements of additional or alternative elements may be used. At least a subset of these elements may be collectively implemented on a common processing platform, or each such element may be implemented on a separate processing platform.

Also, numerous other arrangements of computers, servers, storage devices or other components are possible in an information processing system as disclosed herein. Such components can communicate with other elements of the information processing system over any type of network or other communication media.
