Is Ceph any good?

Red Hat Ceph Storage is an amazing storage service that is massively scalable, open source and is a distributed system. It provides you with all the required qualities you would expect from a top tier storage solution. It comprises of an object store, block store and a distributed file system.

Why is Ceph good?

It also has many enterprise features including snapshots, thin provisioning, tiering and self-healing capabilities. Best of all, Ceph is extremely stable and developed for high performance, while also being open source and free of licensing fees.

Is Ceph better than gluster?

In simpler terms, Ceph and Gluster both provide powerful storage, but Gluster performs well at higher scales that could multiply from tera to petabytes in a short time. Ceph does provides rapid storage scaling, but the storage format lends itself to shorter-term storage that users access more frequently.

What is Ceph architecture?

Ceph uniquely delivers object, block, and file storage in one unified system. Ceph is highly reliable, easy to manage, and free. The power of Ceph can transform your company’s IT infrastructure and your ability to manage vast amounts of data.

Does Ceph use RAID?

Replication. In a nutshell, Ceph does ‘network’ RAID-1 (replication) or ‘network’ RAID-5/6 (erasure encoding).

Is Ceph fast?

I did it in my own project — Vitastor: https://vitastor.io 🙂 it’s a block SDS architecturally similar to Ceph, but FAST. It achieved 0.14 ms latency (both read and write) in a cluster with SATA SSDs. Ceph only achieved 1 ms for writes and 0.57 ms for reads on the same hardware. See README for details.

How much does CEPH cost?

$4800 per calendar year for an accredited public health program with three degree levels (master’s AND baccalaureate AND doctoral). $6800 per calendar year for an accredited public health program, sponsored by more than one university, with three degree levels (master’s AND baccalaureate AND doctoral).

What is Ceph in Kubernetes?

Ceph is a highly scalable distributed-storage solution offering object, block, and file storage. Ceph clusters are designed to run on any hardware using the so-called CRUSH algorithm (Controlled Replication Under Scalable Hashing).

How much does Ceph cost?

Is Ceph a database?

A Ceph storage cluster stores data objects in logical dynamic partitions called pools.

Is Ceph a parallel file system?

Ceph originated from Sage Weil’s PhD research at UC Santa Cruz around 2007 and it was designed to be a reliable, scalable fault-tolerant parallel file system. Inktank is now the major developer behind the open-source parallel file system to shepherd its development and provide commercial support.

What is OSD in Ceph?

ceph-osd is the object storage daemon for the Ceph distributed file system. It is responsible for storing objects on a local file system and providing access to them over the network. The datapath argument should be a directory on a xfs file system where the object data resides.
