Direct Attach Cable
A direct attach cable (DAC) assembly is a high performance integrated duplex data link
for bi-directional communication. The cable is compliant with the IPF MSA (SFF-8432)
for mechanical form factor and SFP+ MSA for direct attach cables. The cable, which
can be up to 5 meters long, is data-rate agnostic. Supporting speeds in excess of 10
Gbps, it is a cost-effective alternative to optical links (SFP+ transceivers and fiber optic
cables.) The transceiver with DAC is hot-swappable. You can insert and remove the
transceiver with the attached cable without shutting down the appliance. The Citrix
NetScaler appliance supports only passive DAC.
