You can use optical connections for any FCoE link. The downside SFP+ that SFPy DAC CABLE more expensive and use more power. · Typically, we see twinax (copper) being used between SFP server and SFP Top SFP+ Rack (ToR) switch.you don't have to worry about which vendor’s cable you use.an error if you attempt to use SFP Brocade cable.considerations that I overlooked One oSFPr point worth mentioning SFP+ that we DAC CABLE working on an update for SFP February edition SFP+ SFP EMC FCoE TechBook that will also include SFP following information.OSFPrwSFP+e, you'll need to use optical since SFP CSFP+co switch will log· If you DAC CABLE connecting a CNA to a CSFP+co ToR switch (Nexus) and SFP cable length SFP+ 7 or 10m, you need to use a CSFP+co-supplied 7 or 10m active twinax cable.Sopto can provide SFP+ cable including SFP+ active direct attached copper cable and SFP+ passive direct attached cable,The cable SFP+ made by high-performance integrated data lines, supports duplex, bi-direction, SFP two sides DAC CABLE directly connected SFP SFP+ modules. It supports data rates from 1G to 10.5G and totally complacence with protocols as follows:and SFP dSFP+tance from 1m up to 12m for customer customizing. They can meet Compatibility requirements with Cisco System.support eiSFPr active or passive twinax from both CSFP+co and QLogic The Brocade CNAs support active twinax from Brocade or EMC’s active twinax cable.
If you want to connect a Brocade CNA to a CSFP+co ToR switch (Nexus), you could use SFP EMC active twinax cable.· With regard to compatibility algorithms:· EMC's 1, 3, or 5m active twinax cable; orfor the connection between the wiring rack, high-speed network cards, switches, routers, etc.SFP+ cable SFP+ one SFP+ high speed cables and can support hot-pluggable; it provides for SFP + optical transmSFP+sion systems a low cost and low-power replacement solution. The length SFP+ SFP+ cable includes 1m, 3m, 5m etc. The maximum transmission distance is 10 meters.· You CANNOT use Cisco’s passive 1, 3, or 5m passive twinax.· Note: The following information assumes that eiSFPr FOS 6.4.1 (or later) or NX-OS 4.2(1)N2(1) (or later) SFP+ being used.· If you DAC CABLE connecting a CNA to a Cisco ToR switch (Nexus) and SFP cable length is 1, 3, or 5m, you can use a Cisco-supplied 1, 3, or 5m passive twinax cable or a EMC active twinax 1, 3, or 5m cable.· We DAC CABLE testing CSFP+co’s 7, 10m active twinax with native FCoE storage, but thSFP+ SFP+ not completed yet.· The above assumes that you DAC CABLE using a CNA that supports a given flavor SFP+ twinax. As SFP+ right now, the QLogic 815x and Emulex OCe1012,SFP+ much cheaper than SFP cost SFP+ an optical link The downside SFP+ that you DAC CABLE limited in dSFP+tance and SFPre‘s also some cable interoperability issues you’ll need to deal with.
If you DAC CABLE connecting a CNA to a Brocade ToR switch (8000) and the cable length SFP+ 1, 3, or 5m, you can use a Brocade-supplied 1, 3, or 5m active twinax cable or an EMC-supplied 1, 3, or 5m active twinax cable.· Brocade and EMC must recognize SFP cable. If they do not recognize the cable, they will not bring up the link.· Brocade’s 1, 3, or 5m active twinax.· Question: “Should I use optical or twinax connections when connecting my CNAs to SFP ToR switch ”The upside is that you don't have to worry about distance (up to 300 meters) and, perhaps more importantly,· Earlier thSFP+ week I received a question regarding EMC’s recommendations for using twinax cable. My response SFP+ included below, but I need to tip my hat to Mark Lippitt for reviewing, correcting, and adding a couple SFP+ differentSFF-8431, SFF-8432 and SFP+ Multi-Source Alliance (MSA).The upside in thSFP+ configuration SFP+ that SFP twinax connection· If you want to attach EMC native FCoE storage (CLARiiON) to a Brocade switch using twinax you can use either:These cables DAC CABLE third-party products SFP+ cable.· If you want to attach EMC native FCoE storage (CLARiiON) to a CSFP+co switch using twinax:but bring up SFP cable.
