FastFrame NQ41 Single 40GbE NIC PCEIe 30 QSFP Low Profile

FastFrame NQ41 QSFP+ Optical Interface
The ATTO FastFrame single-port NQ41 Optical Ethernet Adapter draws less power than competing solutions while providing faster throughput, meaning users can transfer more data at a lesser cost than the competition, enhancing the Total Cost of Ownership of the ATTO 40GbE solution. NQ41 includes QSFP.
In addition to broad support for Windows and Linux server and desktop operating systems, ATTO is a leader in high performance I/O connectivity for Mac OS X environments (Mac OSX Driver release TBD).
