Top of rack switch vs core switch.
Though core switch price is higher than a normal switch deploying best core switches in the core layer is a must to ensure a reliable backbone.
Advantages limitations of tor top of rack approach.
Top of rack switching is a network architecture design in which computing equipment like servers appliances and other switches located within the same or adjacent rack are connected to an in rack network switch.
After practical installation however engineers found that top of the rack is better due to easier accessibility and cleaner cable management.
We can stack up to nine 3750 x switches and have 432 x 10 100 1000 ports and 18 x 10 gbps ports.
We can do this using only 9ru s of rack space.
Compared core switch vs edge switch core layer switch owns advanced features in hardware and software to cater for high end applications.
One is the redundant access switch deployment which usually demands two high speed and individual tor switches that connect to the core network.
In highly virtualized data centers top of rack switches may even be 10gbps across all ports an expensive high performance option.
A tor switch could be at the top of the rack but the actual physical location does not necessarily need to be at the top of the rack.
This makes these switches very popular as top of rack switches in the data center.

Middle of rack vs top of rack switch placement.
If for some reason you are using coax to connect to the core then tor might be the only way to reach the spine switches.
A chassis would require over double the rack space to achieve this access port density.
Despite its name top of rack tor switches can be placed anywhere in the rack.
In turn these network switches can be connected to aggregation switches using one few cables.
