Selection of a switch in a stack?

Question

Cisco

Task:
There is a server with four 1Gb Ethernet ports.
It is necessary to increase the bandwidth to at least 1.5Gbit
AND increase network fault tolerance.
Regarding the traffic, I will answer the software that constantly generates 1.5Gbit of traffic
To increase the throughput, we use EtherChannel (2 ports) The
question about network fault tolerance at the switching level is still open.
In general, I'm tedious to organize a cross-stack etherchannel, but in a budget version.
As a result, it has two switches in the stack, EtherChannel (4 ports) is configured on the server, two links to one switch, the other two links to another switch.
So that questions do not arise, this business is done in a very remote room.
At once I will say not to offer the Catalyst 3750, due to its very high price

Answer 1

If the 3750 is expensive, look into the 2960X... 80 Gb/s stack bandwidth.

Answer 2

Check out the Enterprice line from Alcatel-Lucent

Answer 3

cheap switches do not support such an ethernet

Answer 4

Don't forget that an etherchannel of two gigabit ports can actually give you 1+1 gigabit, not 2, if the source/destination address pair is constant.
