Ceph with OpenStack

2. Optimizing Hardware

Workflow for provisioning Storage

Hardware Choice?

1. Price • Whitebox vs brand? • Support?

2. Reliability • How many replicas? • How many geographic locations?

3. Performance • How large will you scale? • Networking throughput, post, latency? • Hardware load balancing

4. Scale • How much capacity to start? • What is the growth rate over 12mon/24mon?

Scale

“Think Big – Do Small”

Bắt đầu với kiến trúc và lượng tài nguyên tối thiểu để dựng đầy đủ các thành phần, nhưng phải đảm có khả năng mở rộng về sau.

Performace

Benchmark and Monitoring!
