The firmware thing was what caused me to start recommending other server manufacturers. The Sun hardware was actually really nice, well designed, and very stable. The ILOM was great since it was so tightly integrated with the hardware and yet completely out of band, and was included with the server at no real additional cost.
Then Oracle bought Sun and turned off firmware support unless you had an active support contract. That was a big *fuck you* to everyone who bought a bunch of Sun hardware and only kept support on a few critial units. I know firmware updates aren't free to make, but that's the price of good customer service.
Oracle, you've lost my business.
