I am in the process of sourcing our company's first SAN as we have the need for high availability/shared storage. I have noticed fibre channel switches are extremely expensive, and for redundancy we will require 2 of them, costing around $12000 on the low end. The SAN we are looking at (HP MSA 2040) comes with 8 fibre channel ports, and we will only require 6 total (2 per ESXi server * 3).
So my questions are:
Can we directly connect the SAN to the server HBA and skip on the switches?
Will we still be able to use vMotion and High Availability using direct connections from all servers?
