Therefore unlike top of rack where each rack is its own managed unit with end of row the entire row of servers is treated like one holistic unit or pod within the data center.
The topic top of rack vs end of row has been under a hot debate when it technicians talk about data center designs.
Eor end of row design.
The end of row switch provides connectivity to the hundreds of servers within that row.
At higher ethernet speeds where the cabling costs are outsized there is sense to placing the switch in the middle of rack but there are tradeoffs.
This is especially true in situations where you are deploying high density racks with 40 80 servers per rack.
Top of rack tor and end of row eor are two common infrastructure designs for data centers.
In the top of rack design servers connect to one or two ethernet switches installed inside the rack so that all copper cabling for servers stays within the rack from the server to the rack switch.
