Hello Everyone.
Here is the scenario; Users are trying to copy large files roughly 10-30gb files over the WAN from Server A (county 1) to Server B,C,D (county 2) which are located in two different counties. All of these servers are virtual servers and are in a clustered environment.
Our users are on windows xp: Their process is they UnC to both the file shares and have two windows opened and execute the the copying of files by dragging and dropping. Now when they copy files from county1 to countyB the NIC on the server B is roughly around 750 mbps I/O.
When they start copying from Server A to Server C at the same time the NIC reaches a max of 180 mbps I/O.
County 1: all esx host are connected to a cisco 6509
County 2: all esx host are connected to a nexus 5020
I then started to perform test; I downloaded a program called lan speed test. I was getting anywhere from 16-40 mpbs for read/write. The wide range was due to user congestion during peak times of the day. However there were times I was getting a windows delayed write failure.
After further research I disabled write caching (did not work) hard coded the nic on my pc, access layer switch to 1gbps. This still did not fix the issue.
However just a few minutes ago I decided to RDP into the Server located at County B, opened the shared path to the files in County A and drag and drop the files over. I did this for multiple servers and was able to get 750+ mbps network I/O from all servers while copying the files at the same time...(*to clarify I was able to copy at 750 mbps for Each Server not a total)
if someone can please help or elaborate I would appreciate any help.
