Embodiment 1
[0042]The invention provides a storage system IO thread optimization method, the IO thread includes a SCSI IO processing thread and a cache processing thread, and the total number of IO threads is fixed; see figure 1 as shown, figure 1 It is a flowchart of a process of a storage system IO thread optimization method provided by the present invention. The method includes:
[0043] Step s101: detecting the cache utilization rate of the storage system in real time; the cache utilization rate is the cache ratio occupied by the data in the cache that is not synchronized to the storage medium;
[0044] Step s102: judging the cache utilization rate according to the first preset strategy, and obtaining the judging result;
[0045] Step s103: Adjust the allocated numbers of the two types of threads in the IO thread according to the judgment result and the preset adjustment strategy.
[0046] The present invention provides a storage system IO thread optimization method, judging the st...
Embodiment 2
[0048] Based on the first embodiment, the present invention also provides another storage system IO thread optimization method, see figure 2 as shown, figure 2 It is a flow chart of another storage system IO thread optimization method provided by the present invention.
[0049] The method includes:
[0050] Step s201: detecting the cache utilization rate of the storage system in real time;
[0051] Step s202: judging the cache utilization rate according to the first preset strategy, and obtaining the judging result;
[0052] Step s203: Adjust the allocated numbers of the two types of threads in the IO thread according to the judgment result and the preset adjustment strategy.
[0053] Specifically, the size of the cache utilization rate is judged according to the first preset strategy, and the judgment result is obtained; the process of adjusting the allocation numbers of the two threads in the IO thread according to the judgment result and the preset adjustment strategy ...
