An administrator is concerned about the amount of data that a VM is reading and writing to the storage fabric.
Which metric will provide that data?
An administrator is concerned about the amount of data that a VM is reading and writing to the storage fabric.
Which metric will provide that data?
The metric 'VM Storage Controller Bandwidth' specifically relates to the amount of data being read and written by a VM to the storage system, measured in terms of data transfer rate (e.g., KB/s or MB/s). This directly addresses the administrator's concern about the amount of data traffic to and from the storage fabric. The other metrics either refer to different levels of measurement or measure different types of performance.
Amount of data = bandwidth
Both Answers B & C are Valid, the IOPS mean the number of Operations Per Second, to calculate the bandwidth we need to multiply the IO * the Block Size. for the controller bandwidth it tell us the answer of the question (the amount of data ...)
B is the answer. Bandwidth is the size of the pipe. ie; I have a 100mbit network connection. This does not talk about the amount of data been utilized by the VM or its activity on the network. IOPs on the other hand are the input / output operations per second. ie; how much data is been read and written based on the amount of operations.
how much data mesured by the Bandwidth not the IOPS. IOPS used to indicate the performance.
I think is B IOPS=Input/Output operations per second from disk. Bandwith=Data transferred per second in KB/second from disk. https://portal.nutanix.com/page/documents/details?targetId=Web-Console-Guide-Prism-v6_6:wc-analysis-metrics-r.html
The Correct Answer
the answer is B
