Bare metal server data disk hot plugging method under Feiteng CPU architecture based on intelligent network card

Abstract

The invention belongs to the technical field of computer operating systems and hardware design, and relates to a hot plugging method for a bare metal server data disk under a Feiteng CPU architecture based on an intelligent network card. According to the method, an NVMe driver is introduced, only one PCIe resource is occupied for an NVMe control device, a data disk is inserted into a host through Namespace, the insertion of the data disk is completed by the NVMe driver, and the PCIe device does not need to be additionally inserted; meanwhile, an intelligent network card with an operating system is introduced in the method, the intelligent network card is connected with the far-end cloud disk, and then the far-end cloud disk is mapped to the NVMe Namespace through the operating system in the intelligent network card and network card firmware and transmitted to the host for use. According to the method, excessive PCIe resources do not need to be occupied, the number of connected data disks is greatly increased, the limitation of a Feiteng CPU is avoided, hot plugging is achieved, the use convenience is greatly improved, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of computer operating systems and hardware design, and in particular relates to a method for hot-plugging a data disk of a bare metal server under a Feiteng CPU architecture based on an intelligent network card and its application. Background technique [0002] In the bare metal server scenario in the cloud field, traditional local disk bare metal servers usually use the following two solutions for disk expansion: One solution is to insert a physical disk on the spot, but this operation is complicated, cumbersome, inconvenient to manage, and expensive. The operating cost makes the possibility of realizing disk expansion of traditional local disk bare metal servers basically zero through this solution; another solution is to achieve elastic expansion and disk hot loading through bare metal services connected to remote cloud disks, but this solution exists Serious defect, because it needs to connect to the rem...

Problems solved by technology

[0006] In order to avoid the problem that the CPU cannot respond to the data disk hot-plug interrupt under the Phytium CPU architecture, we have made the following design: because the virtio-blk protocol is limited to one data disk for each PCIe resource, we try to introduce a The resource can correspond to the drive type inserted into multiple data disks, and NVMe is finally selected
