I am currently doing k=8 and m=2
or in other words data = 8 + parity = 2 shards
I am using an all hdd ceph cluster.
I have thought about going data = 11 + parity = 2 which would save a lot of data.
Theoretically, you can keep on going up but what would you suggest is a good balance for the purposes of storing data such as images (200kb-1mb in size) + smaller thumnails of 30-50kb and icons of around 10kb.
What block size would you go for?
