It should work fine, like most Areca boards. I have to point out it is
not a SAS but only a SATA model, tho.
Do not expect to be able to plug it into a SAS expander, only
direct-attachment is possible AFAIK.

All Areca models worked out of the box.

This is something I have yet to check. Howewer, the ARC-1260 has an
ethernet port and you can directly manage it from the network, without
the need to install tools on your main operating system.

HAMMER has been production-ready for years now, there shouldn't be
any reliability issues.

Someone else will have to answer this question, I've not tried to expand
a HAMMER volume yet.
