https://community.hpe.com/t5/msa-storage/eva-4100-switch-expansion/m-p/963622#M3956 Hello,<BR /> <BR /> We have an single HP San Switch 4/8 with 4 ports enable. This is a single point of failure. We want to buy another San Switch to work together with the existing switch. What are the requisites for this new SAN switch? Can it be from a different vendor or can it be bigger (in port number) than the existing one?
