Hello Everyone , I am looking for a suggestion and if you could confirm few points that I am going to mention I have a network infrastructure that spread over many sites , those sites are connected by MPLS Network " Hub & Spoke " . The current local infrastructure in each site is considered as a simple infrastructure , few switches , router & firewall and for sure the MPLS Router" Switch " . we are upgrading the whole infrastructure in the main site " The Hub Site " , we are implementing an HCI Solution " it is not HyperFlex :( " . The solution that the other vendor is provided has ToR Switch that provided by the Vendor it self . In the Vendor documentation , and for the best practices , there are assuming that those ToR Swthces will be connected to Upstream Switches through SFP+ Connections , the number of Up-links ports needed in each switch should be 4 SFP+ . I have checked Cisco Website and I am assuming that one of the Cisco Catalyst 9200 or 9200L will be a good fit , what is your suggestions . I am checking that to have full redundancy and the optimal way to configure both Dell Switches and Cisco Swithces is based on what is called " vPC in Cisco , VLT in Dell " however vPC is a nexux feature . I check and I saw that VSS is kind of similar to VPC in Catalyst . based on search result , it seems that it is available only on Catalyst 6500 . any suggestions or help ?
