What exactly is “performance”? How well a gadget, software, or service performs in terms of reaction time. When we talk about the performance of a car or bike, we look at how fast it can travel and how much it costs. Deviation The discrepancy between the expected and actual results is defined as the deviation. …
There are many causes for host unable to discover the storage over FCoE. Such as VLAN configuration on FCoE switch, improper zoning, driver issues etc. In this post, we will talk about VN2VN mode. What is VN2VN mode and how it makes a difference? VN2VN mode: Virtual N_port to VN_port connecting two FCoE adapters on …
