[glue-wg] Some doubts

[Riccardo Zappi]

Hi all,
I'm sure that I've missed something.. sorry for that.
By tomorrow (or by Friday) I'll try to create an over-complicated 
scenario for StoRM and map it into the current Glue Schema for storage.

Now, I've some doubts:

A) StoRM can manage, at the same time, different VOs. Any VO could use a 
different set of access protocol. For example, the StorageShare-1 could 
supports 'FILE', 'RFIO' and 'GSIFTP' protocols, while the StorageShare-2 
(used by a different VO) 'FILE' protocol only.
So, I think that StorageAccessProtocol should be linked to StorageShare, 
not with StorageService.

B) DataStore entity should model, in a synthetic and simple form, the 
concept of the storage hardware (If I've understood well!).
I imagine a cluster file system (GPFS for example) installed on a 
storage area network. In this context, the DataStore is the storage area 
network plus GPFS. How can define DataStore to include the GPFS 
characteristics? Using OtherInfo property? Perhaps we can add another 
property to define the software managing the hardware.

Bye,
Riccardo
