Swift isn¹t the easiest project to understand. You will probably find the docs around it helpful. Based on your questions so far I think starting here would be most useful: http://docs.openstack.org/developer/swift/overview_architecture.html
Andrew Kerr Subject: Re: [Openstack] storage virtualization thanks for reply Cedric what does swift do for adding more devices as storage node? how does swift abstract storage from the devices? And how swift recognise whether there is free space on a particular storage node to store data? On Sunday, 2 February 2014 4:23 PM, Cédric Lemarchand <[email protected]> wrote: As of my comprehension and the way you ask, swift didn't "virtualize" the storage, there are no layer between the swift stack and final storage. The back end are simple FS (ext4 or xfs, or else) on which data are stored (replicated x times/check summed ect ...). Of course the objects are not stored "as is", like on a simple file server. Cheers -- Cédric Lemarchand Le 2 févr. 2014 à 10:37, pragya jain <[email protected]> a écrit : I am not talking about cinder. My question is: Openstack swift provides storage as a service to the user so that user can store their data offline. when a user store some data on swift using Object PUT command, data is stored as an object at some storage node. 1. What is this storage node - Is it a physical hard disk? 2. to store the data, Is swift virtualize the physical storage or directly store the data on physical disk? 3. Is there any need of storage virtualization in swift?
