SavVol Question Relating to E20-324 and E20-545 Courses

Hi,

I am currently preparing for the VNX certification as part of the EMCTA but I've come across some inconsistencies around SavVol capacity in a VNX that I need clarified. The slides describing SavVol size are different on both courses, the notes under each slide are different again, and the instructor contradicts the slide in the E20-324 course!

Here's what is said:

If PFS <64MB then SavVol is 64MB  - General agreement here although the 324 course uses 64MiB (we'll let that one go!)

If PFS <10GB and PFS >64MB then SavVol = PFS size  - Instructor and 545 course agree with this, the 324 course says 20GiB rather that 10GB. The instructor also says 10GB but I know the exams tend to rigidly follow what was in the course notes. Which should i follow for the exam purposes?

Finally

If PFS >10GB the SavVol = 20GB  -  Again 545 course slide  agrees, but instructor says SavVol would start at 10GB in this case. The 324 course says if PFS > 20GiB the SavVol is 20GiB but the instructor disagrees with this as well!

So my simple questions are -

1) What is the official version of the rules determining SavVol size (from an exam perspective)?

2) Would we be expected to give two different answers when taking these 2 exams?

Thanks
