Replicated and erasure coded pools have allowed for multiple copies to be kept, easy scale-out of additional nodes, and easy replacement of failed hard drives. The solution continues working even when there are errors.
Ceph has simplified my storage integration. I no longer need two or three storage systems, as Ceph can support all my storage needs. I no longer need OpenStack Swift for REST object storage access, I no longer need NFS or GlusterFS for filesystem sharing, and most importantly, I no longer need LVM or DRBD for my virtual machines in OpenStack.
Data redundancy is a key feature, since it can survive failures (disks/servers). We didn’t lose our data or have a service interruption during server/disk failures.
We are using Ceph internal inexpensive disk and data redundancy without spending extra money on external storage.
The two 10GE networks provide redundancy and increased performance as they serve as two separate networks doubling the throughput and doing multipathing and load balancing. We now have a high performance shared storage system which enables us to run on private cloud. Our previous system used bare-metal hardware, which provided high performance but inflexible management. Now we have best of both worlds, SSD-class performance with flexibility of a private cloud system.
With StorPool we were able to build live failover on top of our LXC infrastructure. This allows us both to live-migrate containers between compute nodes without any downtime and, in case of an entire node suffering any type of failure, we can bring all containers back online within a minute on a spare compute node.
The speed of the storage solution also allows us to provide service to applications that are very I/O intensive.
I have encountered issues with stability when replication factor was not 3, which is the default and recommended value. Go below 3 and problems will arise.
This product uses a lot of CPU and network bandwidth. It needs some deduplication features and to use delta for rebalancing.
In the deployment step, we need to create some config files to add Ceph functions in OpenStack modules (Nova, Cinder, Glance). It would be useful to have a tool that validates the format of the data in those files, before generating a deploy with failures.
Ceph is not a mature product at this time. Guides are misleading and incomplete. You will meet all kind of bugs and errors trying to install the system for the first time. It requires very experienced personnel to support and keep the system in working condition, and install all necessary packets.
At times we need to check the disks and do some minor operations. A friendlier user interface would be useful in such cases.
It would be good if, with next releases, StorPool provide a better GUI for monitoring and statistics. This would make our experience even better and complete.
Pricing and Cost Advice
If you can afford a product like Red Hat Ceph Storage then go for it. If you cannot, then you need to test Ceph and get your hands dirty.
StorPool's pricing and licensing model is very transparent. As always, one has to due his due diligence when choosing a product like distributed storage solutions.

|Overview||Red Hat Ceph Storage is an enterprise open source platform that provides unified software-defined storage on standard, economical servers and disks. With block, object, and file storage combined into one platform, Red Hat Ceph Storage efficiently and automatically manages all your data.|
StorPool is intelligent storage software that runs on standard servers and builds scalable, high-performance storage system out of these servers (software-defined storage). It focuses on the block-level storage and excels at it. It is incredibly flexible and can be deployed in both converged setups (on compute nodes, alongside VMs and applications) or on separate storage nodes.
StorPool has advanced fully-distributed architecture and is arguably the fastest and most efficient block-storage software on the market today. It is the best storage system when building a cloud.
