Components for Ceph
Ceph storage from Thomas-Krenn

In this age of rapidly expanding data growth and the advent of cloud frameworks, such as OpenStack, retail outlets are constantly adjusting to new challenges and realigning to market needs. Storage systems with Linux-based open source software using standard server hardware have already established themselves on the market as being reliable and flexible.  The following offers you hardware components that allow you to optimally use Ceph storage in your company.

Object-based Storage

Many companies prefer object-based storage when building large, highly-scalable storage systems as this allows the data volumes to be managed much more efficiently. These systems separate the addressing of the object from the corresponding hardware, which greatly simplifies data migration.

The Crush algorithm from Ceph frees storage systems from the limitation of centrally managed identification tables. This significantly enhances both scalability and speed. A Ceph cluster manages the replication and balance of the data – completely independently and dynamically – without requiring an administrator's involvement in these time-consuming activities.

With the server building blocks, complex storage systems can be easily created that are very powerful and open in their architecture. To simplify the selection for your Ceph cluster, we offer you basic minimum requirements for both monitor (MON) and OSD nodes.

Monitor nodes are tasked with monitoring the system and act as the central management for the Ceph cluster. These servers can also be operated virtually, though, the use of one to three physical monitor nodes is recommended. OSD nodes provide the actual data storage for the objects and can be scaled according to the desired redundancy level. For a replication factor of three, for instance, one will need at least three OSD nodes.

For more technical information on Ceph, please visit our wiki.

Example configuration:

OSD nodes (2U): 2x 400GB SSD + 10x 4TB HDD
OSD nodes (4U): 6x 400GB SSD + 30x 4TB HDD

Please note that our proposed configurations only serve as a general guideline and that these may need to be adapted to your respective environment and/or requirements.
