Hello there
As our Riak CS cluster grows, we went through several performance
problems which caused me to think we went a wrong way with planning our
hardware nodes configuration probably.
If we want to have an s3 cluster with 30-40 Tb capacity, 50-100 millions
of keys (files) stored on few thousands of buckets with n_val=3 which
way to choose hardware configuration for nodes would be better:
1. more nodes with less memory and hdd capacity each. Let's say 18 nodes
with 40 gb ram and 8 tb storage per node
2. less nodes with more memory and hdd capacity each. Let's say 12 nodes
with 64 gb ram and 12 tb storage per node
3. even less nodes with even more memory and hdd capacity each. Well,
for example 6 nodes with 128 gb ram and 24 tb storage each
Or is there a dependency between total cluster memory and total cluster
storage capacity? What is our maximum storage capacity if we have 768 gb
ram in total in our cluster in other words?
