proxy_cache_path with huge zone size

I have some troubles to configure my reverse proxy cache.
I would like to use a proxy cache with about 5 TB.
If I estimate an average file size of 128KB, I need to define my zone size
to about 5GB. (5 TB / (128KB / 128))
Here the configuration line:
proxy_cache_path /opt/.../hdd_storage/cache levels=1:2
keys_zone=proxyCacheZone_hdd:5000m max_size=5000g inactive=1d;
Now, as I have 16 CPUs, I defined 16 worker_process.
The problem is, for each worker an allocation of 5 GB is done for a total of
80 GB of ram usage!!!
Do I have misunderstood somethig?
Is there a way to used a shared memory between workers for the zone cache?
Thank you in advance
