Hello, tjkc80. So, the quick answer is no. You'll not be able to do that. In the case of the NX, it's simply an R710 that we've rebranded, attached an MD for added storage, and sold them as one appliance. You're able to "rebrand" that back to an R710 because it was once an R710. In the case of the SC8000, it has only ever been a powerful storage controller. It can't be "flashed" into a server of any kind, as it has never been a server. It is built and designed as a storage controller.
Is there a way to flash a Compellent SC8000 BIOS to make it an Dell Poweredge R720 BIOS? Similar to how you can flash a NX3000 BIOS to make it an R710. I've tried flashing the BIOS several different ways including the DOS update and adding /forcetype, /brandname, and /forceit. Any help would be appreciated.
