我有一台通过光纤连接到 NetApp SAN 的 OEL 服务器。如何像操作系统一样查看队列深度?

答案1
我对 NETAPP 的看法是:
ls /proc/scsi/qla2xxx
1
ls /proc/scsi/qla2xxx/1 | grep -i -A1 -B1 "queue depth"
Total number of interrupts = 30686605
Device queue depth = 0x20
Number of free request entries = 1842
因此 x20 的十进制数为 32,这就是您要查找的 #。您可以在此处阅读有关 NETAPP 的计算:

编辑:其他一些方法可以看看:
cat /sys/module/qla2xxx/parameters/ql2xmaxqdepth
答案2
最简单的方法是
cat /sys/block/<sdX>/device/queue_depth
