direct connection between MSA2040 and MSA2050

hi Community

for replication purpose, I should do a synchronous replication between MSA2040 and 2050 ,unfortunetly my client hasn't the budget to purchase a switch SAN 

it's possible to have a direct cabling over FC between MSA2040 and MSA2050

so if not ,could you suggestion me a solution for this replication 

please note actually that the two ESXi in cluster are connected to MSA2040 and I should integrate the MSA2050 and replicate a virtual replication as the  virtual volume are configured in MSA2040 

please your help
