“Sharding” means “split across multiple physical persistent storage”.

 
It means that you have N active database servers each with 1/N of the
data (possible with replication to N or 2N passive database servers).

Quite unnecessary, given that the bottleneck is the usually the latency
and bandwidth of the persistent storage, not the CPU.

Particularly since your network connections introduce latency and
bandwidth limitations of their own.

See what I mean about “tradeoffs”?
