Kanan, the difference you already know, blade .vs rack mount. There are some CPU differences, but not much. Both can be managed by UCSM in version 1.4.x
So it really is ones preference on what you are using it for and how scalable you want things to be for future expansion.
Blades: easy, as you can buy a chassis and have 2 blades in that one chassis and add blades as needed. If using boot from San, can get a server back up in minutes
Rack mount: can take rack space more quickly, takes time to duplicate in case of a failed server
Very small differences, but hope this helps to start the wheels turning.
Good Luck!
