This page describes compares build hardware options for arm hard float both currently available and possiblly available in the future.

In general red means poor, yellow means ok and green means good. White means insufficiant information available to assign a color. These judgements are somewhat subjective but I (plugwash) belive them to be reasonable. See the table at the bottom for details of the color codes.

Prices may be approximate and/or outdated and are given for guidance only.

form factor

looks like a massive pain to mount in a rack.

looks like it could be fitted in a rackmount case or to a rack shelf with a little effort

can be trivially racked (either comes in a rackmount case or comes as a stanard PC form factor board for which rackmount cases can be purchased)

kernel support

no usable support in debian and a vendor kernel that does not seem to be getting updates.

either adequate (ethernet, SATA (either native if present or an external usb controller if not) and some means of getting a console work) but not full support in debian kernels or a vendor kernel that is reasonably up to date

full support in debian kernels
