Hello I am using the support of unapplied PS6100XS in six pieces of Hyper-V cluster environment of WindowsServer2012R2. I am perplexed at the sudden performance down of this PS6100XS. For now, the throughput with 460 MB / S is confirmed but at present, it is a performance with the 100 MB / S degree. The work before this phenomenon happens was the following in me. It is the shutdown of the cluster for the maintenance. A cluster node is restarted for the maintenance. It installs the role of the overlap exception in all cluster nodes. I think that it wants to do the advice where someone is suitable for me. Thank you.
