FastFrame NQ41 Direct Attach Interface
The ATTO FastFrame single-port NQ41 Direct Attached EthernetAdapter draws less power than competing solutions while providingfaster throughput, meaning users can transfer more data at a lessercost than the competition, enhancing the Total Cost of Ownership ofthe NQ41. Support for direct-attach copper allows users to tailortheir 40GbE solution according to their infrastructure needs andpreferences.
In addition to broad support for Windows and Linux server anddesktop operating systems, ATTO is a leader in high performance I/Oconnectivity for Mac OS X environments (Mac OSX Driver releaseTBD).
