Volumes combine pools of storage across different indexes so that they age out together. Let's make up a scenario where we have five indexes and three storage devices.
The indexes are as follows:
Name Data per day Retention required Storage needed web 50 GB no requirement ? security 1 GB 2 years 730 GB * 50 percent app 10 GB no requirement ? chat 2 GB 2 years 1,460 GB * 50 percent web_summary 1 GB 1 years 365 GB * 50 percent
Now let's say we have three storage devices to work with, mentioned in the following table:
Name Size small_fast 500 GB big_fast 1,000 GB big_slow 5,000 GB
We can create volumes based on the retention time needed. Security and chat share the same retention requirements, so we ...
