STORAGE PARTS

OPEN STACK

Block Storage

- Is always the base

- There are Object Storage Daemons (OSDs) and monitors

- leverage RADOS capabilities such as snapshots, replicas, consistency

- high performance to kernel modules or to KVMs (such as Qemu)

- kernel modules can use Linux page caching

- for librbd based applications you can use RBD Caching

- Constantly restriping and rebalancing in the backend

- Use locations and regions for replicas across datacenters

- For Glance replica 2 is okay, set replicas up to 8

- limit the size via Quotas

- Combine with Glance, Cinder and since Havanna as guest disks (live mig.)
