Recommendation About Architecture of 2 SHARD with Total 3 Servers only

Dear Experts,

I have designed an architecture for our up coming project so I am looking recommendation from your side

There are total 3 Servers

Server01

dtnode1 rep01
dtnode2 rep02
cfgnode1 cfg01
mongos

Server02

dtnode1 rep01
dtnode2 rep02
cfgnode1 cfg01
mongos

Server03

dtnode1(Arbiter) rep01
dtnode2(Arbiter) rep02
cfgnode1 cfg01

Shard01 → rep01
Shard02 → rep02

Data should be for 1 year is around 7 TB and Data velocity is around on every 5 seconds so please share your feedback about this architecture will work well or any type of problem we could face

Too bad a reply needs to be 20 characters. Because the answer is simply DO NOT.

You only have 3 machines, do not make them suffer by having to do context switch between 2 instances of mongod.
