I think it's the economic factor. This solution has the lowest cost for storage systems.
What needs improvement?
If I had to choose a new aspect for the system, it would be the rebalancing. The ease of use during capacity upgrades would be the most important improvement. I don't know if they manage it better right now or not, but it was really horrible to extend capacity on Scality at the time that I used it.
When you add new servers in the node or ring, Scality does rebalancing to split the workload across all the nodes and servers. It moves the data from one server to another.
For how long have I used the solution?
I did a backup for someone else, so I only have one month of experience with Scality. I did the project though and from there I just followed up with the associate or management of the project.
What do I think about the stability of the solution?
This solution is stability.
What do I think about the scalability of the solution?
When we used this solution in 2015, it was not scalable at all. I don't know if they have improved on that, but at the time, scalability was just horrible.
It's used within Orange in France, which handles petabytes of data. I don't know exactly how much it was, but I think we are talking about five, or even more than that. When I worked on this project, it was during migration. It is definitely getting higher and higher in terms of capacity that you can use.
How are customer service and technical support?
Scality's technical support team is good.
Which solution did I use previously and why did I switch?
I'm starting to work on a project now with ScaleIO. The engineering team suggests migrating to Red Hat Ceph. I don't know yet what their reasons are, but that was the information I got two weeks ago. I am now starting to look for information comparing the products. For the project I'm working on now, we need block storage, so Scality is not an option in this case. Scality is used for object storage and here we are talking about another solution for block storage. Today we are using ScaleIO, which engineering recommends. It's a common thing to migrate to Red Hat Ceph.
How was the initial setup?
My experience in 2015 was that it was not easy. Each time we needed to get the Scality professional services to help us at that time.
What other advice do I have?
I think I would recommend Scality but there is another solution that I'm going to dig into more, which is OpenIO. Right now for new projects, I don't know yet if I'm going to recommend Scality or OpenIO. Most probably OpenIO, but it's not necessarily based on technical features. It's because we have a commercial agreement with OpenIO.
I would rate this solution as eight out of ten.
Which deployment model are you using for this solution?
