Regretting buying the Netgear Prosafe XS708E (8 port 10 Gbe) because of;
It's clunky interface (not web based)
Lack of redundant power supply
Lack of ports
It was a good deal @ £500 but having a rethink i'd rather use a single 10 Gbe switch with redundant power supply than pair the that with a Gbe switch.
Budget it pretty tight...
