fio plugin functions that need to be on an SPDK thread into two parts: 1. fio API callback: transform args from fio into a spdk_fio_oat_ctx structure, then calls spdk_fio_sync_run_oat(). In the case of spdk_fio_setup(), the app thread is started in this part. 2. On App ...
2. 基于bdev的fio_plugin 基于bdev的fio_plugin是将I/O在SPDK块设备bdev之上进行发送。而基于裸盘的fio_plugin,I/O是直接到裸盘上进行处理。两者最大的差别在于I/O是否经过bdev这一层。因此,基于bdev的fio_plugin能够很好的评估SPDK块设备层bdev的性能。其编译安装与裸盘的fio_plugin完全相同。 测试方法 a. ...

fio的测试对象可以是块设备、文件等,在spdk的使用过程中会unbind默认的nvme driver,所以在系统中是看不到nvme块设备的,在spdk中可以通过fio_plugin的方式,将spdk的用户态driver部分的io功能打包成一个ioengine提供给fio使用,可以综合spdk的高性能和fio提供的复杂场景。

The core of this plugin is an ACL engine that checks each incoming request through a sequence of rules a bit like a firewall. There are a dozen rules that can be grouped in sequences of blocks and form a powerful representation of a logic chain. 鹏程 2023/05/02 3.2K0 Python 模版(三...
