JMeter Load Testing on IU HPSS/MDSS

Here is the scenerio I'm proposing:

Test files:
+ 1-10MB
+ 50-200MB
+ 1GB+

Steps in load testing:
1) Log into OGCE
2) Get MyProxy credentials
3) Open file-manager portlet
4) Open connection to BigRed on left
5) Open connection to MDSS on right
6) Upload test file to MDSS
7) Transfer test file from MDSS to BigRed
8) Delete test file from MDSS
9) Transfer test file from BigRed to MDSS
7) Download test file
8) Repeat step 6 with other test files
