Patch for cost reduction of copy to S3
Installation of the
patch will reduce costs drastically for customers who are
using S3 (Between 5 to 20 times less expensive than previous version)
The improvements are:
- For copied volumes which are larger than 512GB, worker’s
volume type will be sc1 instead of gp2
- Better data reading performance which results in
creating up to 2 Worker volumes instead of up to 10 worker volumes for
copying the data to S3
A patch for this issue is included in the latest version of CPM, v2.5.0, please upgrade to see these improvements.
