[Beowulf] Third-party drives not permitted on new Dell servers?

[Mikhail Kuzminsky]

And what is known about other vendors (Sun, HP, IBM) x86 standard 
1u/2u servers ?

SGI hardware even in their "big" UNIX SMPs like Power Challenge 
allowed using of 3rd party drives - although they were not supported 
officially.
