[Fiware-lab-federation-nodes] [Project: #1] Ficore Project: Storage Questions ?

[Sébastien LEFEUVRE]

Hello Fernando,

In order to process to the installation of the Ficore platform, we have 
some technical questions :

_/*1 - Gluster vs Ceph
*/_

Do you have some feedback regarding Ceph and Gluster ?

As we know:

  - Ceph is the most recent storage (Object storage) and have a great 
evolution plans.

  - Gluster is more performent, however, it has been integrated into 
OpenStack most recently and it's not really integrated (Plugins) and 
verified in the last version of the Deployment Tools like (Fuel, ITBox 4).

Regarding the difficulties to change the storage's architecture after 
installation, we need to know which storage we have to use in order to 
growth easily in the future. This, based on your experience.

For both storage solutions, do you have some 
requirements/recommendations about configuration (metadata, journal, 
replications factors, ...) ?


_/*2 - Sizing Vitual Storage (Non persistent) vs Persistent Storage*/_*
*
Could you also tell us , what is the recommended size to dissociate the 
persistent volume (Ceph, Gluster)  and the non persistent volume 
(Virtual Storage). As we've seen, half of total size is recommended for 
each volumes, but do you have any recommendation based on your experiences ?
