Ceph is open source and there are large organizations running huge Ceph clusters which have published blogs on how they deployed Ceph.

Do your research based on the lessons learned from these users of Ceph to decide on which configuration and architecture to use for Ceph.

As organizations move to Linux container based technologies and container orchestration frameworks (especially Kubernetes), Ceph is still relevant as it provides integration into these future technologies to provide block storage for them as well.

It's ultimately all about IOPS. When a failure occurs CEPH tries to 'rebalance' data on the surviving nodes which can consume a lot of IOPS affecting client IO. If there's not enough IOPS or fast data rebalancing, it can take a lot of time to rebalance data. Some of this can be improved with faster networks and faster drives like SSD or flash drives (which people can implement right now in older versions of CEPH), some of the improvements will come from how CEPH writes data using BlueStore and replicate or rebalance data between OSD nodes using RDMA (which may become stable for users in newer versions).

I rate Red Hat Ceph Storage a seven out of ten.

I would rate Red Hat Ceph Storage a seven out of ten.

I'm not sure which version of the solution we're using. It might be around version four. 

We're a reseller.

I'd recommend the solution to other users if they have a Red Hat ecosystem.

I'd rate the solution a five out of ten since it can be complex to install. 

My company is an implementer of Red Hat Ceph Storage. The solution was implemented for two or three customers in the FinTech field, but I don't recall using Red Hat Ceph Storage that often.

My advice to others who may want to start using the solution is that its value is good, especially if you have an entire Red Hat environment, as that is when you'll have the best integration.

My rating for Red Hat Ceph Storage is seven out of ten.

Red Hat Ceph Storage is working exactly as it should be. It's running in the background, and it's working, and it doesn't bother me.

I would recommend Red Hat Ceph Storage. it is a good system. It is important they have knowledge or if they can find somebody to support them. It's not a good solution if you don't know what you're doing.

I rate Red Hat Ceph Storage an eight out of ten.

My suggestion is to try before you buy so you know it's the right solution. It's not one-size-fits-all. The product has plenty of potential for growth, but the parts where we would like to see growth are not necessarily where the vendor is focusing its attention.

I rate this solution seven out of 10. 

I rate the solution a nine out of ten. 

I would recommend others to use this product if they get the chance. I would rate the product a nine out of ten. 

Think twice.

Pick up a copy of this excellent book: Learning Ceph - Second Edition.

Companies that can afford completely flash-based pipe servers should go for Ceph. It's a very performance-intensive, brilliant storage system, and I always recommend it to customers based on its benefits, performance, and scalability. I would rate it as eight out of ten.

I have been using Ceph since 2015, in both SOHO and bigger private cloud installations.

Ceph, as a distributed storage solution, is amazing and I can only rate it a 10 out of 10. However, being distributed and complex, Ceph needs engineers with a good understanding of its internals and Linux, for it to shine.

Overall, it is a great product.

I rate it at nine out of 10. It is a product which is constantly undergoing improvements.

It is easy to set up.

I would recommend the product.

We use the on-premises deployment model.

I'd rate the solution seven out of ten.

Everything is perfect.

When we face a problem, we search the documents to fix the issue. The solution does not crash. It is reliable and scalable. Overall, I rate the product a ten out of ten.
