I was also wondering about this question because RCSP-W blueprint does not mention about any deployment or user guide for SaaS. Although it says that 4 questions will be asked in exam on this topic.
What I have found on SaaS and could be helpful in RCSP-W preparation for this topic is as below:
1.)Steelhead SaaS User Guide RiOS V9.1
2.)Riverbed SCA Software User guide.
3.)SCA setup guide.
