How to Redirect Output from the VSAN Ruby Console to a File

Hi,

I was struggling today to get the output of the Ruby console redirected to a file. I was using the Windows vCenter Ruby Console.

For the Linux vCenter the regular linux redirectors work as usual.

So, in order to get this working you have to modify the rvc bat to look tlike this:

 

The rvc is located here:

 

C:\Program Files\VMware\Infrastructure\VirtualCenter Server\support\rvc

 

..\ruby-1.9.3-p392-i386-mingw32\bin\ruby -Ilib -Igems\backports-3.1.1\lib -Igems\builder-3.2.0\lib -Igems\highline-1.6.15\lib -Igems\nokogiri-1.5.6-x86-mingw32\lib -Igems\rbvmomi-1.7.0\lib -Igems\terminal-table-1.4.5\lib -Igems\trollop-1.16\lib -Igems\zip-2.0.2\lib bin\rvc -c “vsan.support_information 1” -c “quit” administrator:VMware123!@localhost

 

 

Once you have modified the rvc bat, just create a shortcut on the Desktop and modify the Target as follow:

Then, just click on the Shortcut and you will get a text file created in C:\VSAN.log

Troubleshooting File Transfer Performance Between VM’s – Part 2

So, here we are again to finish this chapter.

After getting the Customer on a Webex session we managed to go to the BIOS settings of the DELL Server and change the System Profile to “Performance”.

BIOS Settings

So, we started the ESXi servers and we did some testings.

As a reference, before this change, the average speed to copy a 9 GB file from one VM to other was around 20 Mb/s with some drops during the transfer.

So, here are the results after:

File Transfer Speed After Power Management Change: 55 Mbs

Conclusion:

Power Management really matters !
