Apologies in advance for what might be obviously dumb questions to some, but I am new to Nexus.
1) Why would you buy a 5010/5020 over a 5548UP/5596UP? I've looked at the data sheets, and haven't yet identified the major difference between the 2 ranges.
2) Does the 3064 support 2000 series FEX? I can't find any mention of this in the data sheets.
3) Does Cisco do a RJ45 10g SFP+? I don't think so, as most discussions I found suggest its not a good idea anyway as fibre had better power/latency characteristics.
4) Is there any PoE in the Nexus range? I think not, but just wanted to check.
5) Do most solutions involve connecting servers using 10GBASE-SR or have some found reasons to use Twinax to a server?
6) Does a 10GBASE-SR also support 1gb (i.e. to provide a legacy uplink to a none 10gb 3750 SFP)?
7) In the 5010/5020 or 5548/5596 range, in order to do local L3 VLANs (no WAN dynamic routing), do we need the L3 module? From what I can see that is only supported in the 5548/5596.
Thanks for any help.
1.) The UP series supports 1 Gbps Cu, 1/10 Gbps optical, 10 Gbps twinax and 1,2,4,8 Gbps FC transceivers on every port. The non-UP series can't do that
5.) Most of my customers use twinax cables to connect the servers. The twinax solution is much cheaper than 10 Gbps SR transceivers.
6.) No, you would need a 1 Gbps SX transceiver
7.) If you want to provide inter-VLAN routing you need the L3 module
