Advanced Tuning and Operation Guide for Block Storage Using Ceph
For successful OpenStack deployment, It's very important to properly deploy and tune block storage service, because a performance and durability of VM is completely dependent on it. We researched about performance, durability, HA, reliability and scalability of block storage service from many OpenStack deployments. We want to share experience and knowledge gained through variety test and research. Especially, we performed test both on HDD-base and AF (All-Flash) based ceph cluster. Each environm
