Hi, I agree with Shlomo Although useful, I see support for a special storage device like "floppy drive" being problematic for interoperability across providers. OCCI does support storage, which can be mapped/mounted by the operating systems to any type of drive. Currently, OCCI does not support the mapping of any other drives (ie hdxx, sdxx, cxxtxxsxx, A:-Z:), or any specific storage volume placement in the operating system. Storage device maps are relegated to the internal configurations of the operating systems and should remain there until when or if occi decides to support internal operating system configuration items. I find it difficult justifying altering this strategy for a floppy configuration. Incorporating this special case has much wider impacts to the specification, it adds a currently unsupported feature: "mapping storage resources to operating system devices" which has broad impacts to the specification and will significantly increase the complexity of OCCI implementations for many providers.. -gary shlomo.swidler@gmail.com wrote:
Sam,
I meant "it's not necessary to distinguish a virtual floppy..." for the use case I described (transferring data without using the network).
For legacy apps that rely on a resource called a "floppy drive" it is needed. And I agree that the way to do this is to designate it with an adjective (= attribute), like the word "floppy". If there was some verb that you could do to a "floppy" disk which distinguished it from a non-"floppy" disk then "floppy disk" *might* be justified as a separate noun. [I am of course ignoring the oft-overlooked use case for floppy disks: frisbee.]

Shlomo,
I'd be hesitant to remove legacy support for something that someone somewhere will need. For example you can move the encryption key for the Windows user accounts database (SAM) to a floppy which is consulted at boot (see q310305 <http://support.microsoft.com/kb/310105>), some small linux distributions boot from floppies (or consult them for config - see gibraltar firewall), etc.
However I'd planned to implement this as an attribute and if I remember well they're a noun in vCloud (this is one of my main grievances about vCloud - lots of nouns, albeit far less than its predecessors). Their API is very similar to the current thinking for OCCI, though I think there's still a far bit of unnecessary complexity we can boil off (which is no wonder when you consider its roots).

Randy,
Do share the use case, please?
It could be useful in transferring small amounts of data (e.g. secret account credentials) between machines without using the network. But it's not necessary to distinguish a virtual floppy disk from any other type of disk, as long as you can make a small enough volume size (1.44 Mb?) for the cost to be irrelevant.

I've actually found very good use for these.

It supports virtual floppy disks; clearly we must add this essential feature to OCCI immediately. :-)
