[0033] A method for improving the throughput performance of a solid-state hard drive, comprising the following steps:
[0034] (1) Determine the type of the solid-state hard disk interface, if the solid-state hard disk is a SATA interface or a SAS interface, go to step (2); if the solid-state hard disk is a PCIe interface, go to step (3);
[0035] (2) In order to use the solid-state disk with SAS interface / SATA interface more efficiently, optimize the traditional IO protocol stack, increase the number of queues and the queue depth of each queue, if the CPU core is 8, the queue will be increased to 8, each The queue depth expansion of the queue is 32,256 (the queue length that the SSD can handle) / 8 (the number of queues after expansion) = 32; reduce IO blocking or waiting.
[0036] Use Intel SPDK (Storage Performance Development Kit) to build user-mode storage drivers and user-mode TCP / IP protocol stacks to reduce data copying between user-mode and kernel-mode, avoid context sw...
