Red Hat Ceph Storage Review

We use this as an OpenStack storage back-end

How has it helped my organization?

We use this as an OpenStack storage back-end of Nova/Glance/Cinder.

What is most valuable?

  • High reliability with commodity hardware
  • There is no cost for software

What needs improvement?

I would like to see better performance and stability when Ceph is in recovery.

What do I think about the stability of the solution?

Latency increases abruptly when conducting recovery. This impacts the upper application.

What do I think about the scalability of the solution?

It is OK to add a node or a disk, but it may impact the latency of read/write of the application which is running.

How is customer service and technical support?

The level of technical support is acceptable.

How was the initial setup?

The initial setup was straightforward without much effort.

What's my experience with pricing, setup cost, and licensing?

People can try the vanilla Ceph, if they are confident with their technical skills.

Which other solutions did I evaluate?

We evaluated VMware vSAN.

What other advice do I have?

It is easy to set up.

Disclosure: My company has a business relationship with this vendor other than being a customer: We are partners with RHEL.
