Talk:Ceph (software)

Conflicts of interest
I am concerned that one of the primary editors of this article has a conflict of interest since he participated in the development of Ceph. — Preceding unsigned comment added by 128.114.60.41 (talk) 16:51, 14 June 2012 (UTC)

Disk type ?
Mentions "capacitative disks" - those are not used for data storage ! Perhaps it means "high capacity" ? 150.143.154.250 (talk) 16:59, 1 November 2022 (UTC)

 * Ceph as in cephalopod, as the article explains - sounds like seff. --Streaky (talk) 16:18, 22 May 2012 (UTC)


 * Reading the article as suggested by May 2012 post, "keff" from ke-pha-LEE seems in order? "...The name "Ceph" is a common nickname given to pet octopuses and derives from cephalopods, a class of molluscs, and ultimately from Ancient Greek κεφαλή (ke-pha-LEE)..."? — Preceding unsigned comment added by 153.31.113.27 (talk) 16:53, 6 November 2013 (UTC)

Ceph is a free software distributed fault tolerant parallel file system.

Development

Ceph is still in development, please check out the project homepage at http: //ceph.sourceforgen.net This makes Ceph not suitable for building large systems right now, like Lustre i s.

Features

Like all other free software distributed parallel fault tolerant file systems, which there aren't so many around, Ceph has certain features. Basic ones, like many servers work together is obvious. So let's list the unique ones:


 * Adaptive metadata. This means that a single directory may be distributed among many servers using a hash-like function. A simple example of this may be a mailserver using Maildir for storage, with a couple of millions mail in a single storage, getting hammered by all servers at once.


 * Fault tolerance. Together with GlusterFS, Ceph has built in fault-tolerance. This means a file may be automatically replicated among many servers.


 * High performance. Like GlusterFS and Lustre, Ceph may stripe files over many servers. Ceph has a good througput on also small files, using a custom disk object file system on the servers.

Inaccurate image
I think that File:Ceph-konzept.png is not correct when it comes to cephfs. It suggest that librados is involved. But the FUSE driver doesn't use it and the native FS driver is part of the kernel. I think that this image depicts it correctly: http://storageio.com/images/Ceph_Architecture1.gif

 * Hello! But, File:Ceph-konzept.png and http://storageio.com/images/Ceph_Architecture1.gif depict pretty much exactly the same internal layout?  Did you maybe have another image in mind? &mdash; Dsimic (talk | contribs) 21:42, 19 February 2015 (UTC)

Repair and disaster recovery tools
The CephFS (filesystem) implementation lacks standard file system repair tools, and the Ceph user documentation does not recommend storing mission critical data on this architecture because it lacks disaster recovery capability and tools. The statement is not applicable for the latest release (v10.2.0 is deemed production-ready). The documentation is not up-to-date yet, so that statement can be removed/updated once it has been updated.Wasill37 (talk) 04:20, 22 April 2016 (UTC)

Wikidata version
I have added Wikidata template for latest stable version, but it does not show in the software infobox. Does anyone know how to fix this? kocio (talk) 22:08, 14 November 2022 (UTC)
