Not sure why the core count is part of this discussion, but iirc, the CPU architecture of the chip is heterogenous, which the older kernel of ROS 6.x can't support. Thus only "core 0" shows up as usable.
As to the storage... Why are you trying to free up space? It sounds like you're looking to go back to 6.x firmware. That is really ill-advised for CRS3xx hardware, as support for the switch chip really requires ROS 7.x. We've seen a couple dumb issues months after deployment of switches to customers. In every case, I've had to chide our team for not patching a switch that shipped with 6.x before deployment.
As to performing upgrades, the system/package update feature works just fine, with the limited storage space.
Edit: to be clear, I totally understand why you might want a lot more storage, but more in terms of "I wish the switch supported a microsd or USB storage option". I have a couple of them acting as near all-in-one network heads for things like out-of-band networks, would be excellent if they could provide a TFTP boot server in the same space. Keep thinking I'll get around to embedding a Hex/HAP in one of them, but realistically, not going to add such a hack-job to the product line. The newest Mikrotik gear is fantastic, but I wish there was room for a little more "crazy". Something in the realm of QNAP's half switch/half NAS/half router solution.
That side-trip over, what are you trying to do on the local flash? Rose-storage is an option as well: provision a ramdisk. I've been writing some scripts that I'm worried about wearing through the disk. I've found I can sieze 256mb of flash from a CRS326 with no problems so far.
