Hello
I wanted to understand , if i use WS-X6748-ge-tx with DFC for Server connectivity and if i use Nexus 5000 for server connectivity.
What is the difference in performance which we can see ?
thanks

Hello Rahulja,
first of all, with the Nexus 5000 you may need a fabric extender to be able to connect GE server NICs
in short Nexus provides greater 10GE port density in comparison to C6500
a WS 6748 with appropriate DFC is a good linecard for a server farm and it is targeted to this use.
Hope to help

Hi,
As far as the comparisns between the two just check out the below link for nexus 5000 and cisco 6500 series switches hope that help.

http://www.b2net.co.uk/cisco/cisco_catalyst_6500_series_switches.htm
and check out the below link with nexus 5000 given with different Scenario on basis of performances:-

Hope to Help !!

1. It is possible but you have to understand what is supported with/by the FEX. Like you said, the Nexus is mainly for DC. FEX fabric interface has a 300m limit (from my memory), no 10mb support and no POE (since you said you have 3750X).
2. See 1.
3. See 1. Also, looks like you need L3. With the L3 module inserted into the N5K, this will reduce the number of FEXs to 8.
4. N5K support both 1G and 10G SFPs. And beside, if you use FEX, there are both models, 2248 supports 100/1000 and 2232 supports 1G/10G.
5. You have to decide if you want Nexus 7000 or Nexus 5500. The Nexus 5500 is less expensive when comparing to the Catalyst 6500.

Here are some answers.
1. "reload restore" enable the 5K to try restore the vPC after a reload of one or both of the members. the default delay before try is to wait 240 seconds, using " reload reastore delay 300" change the default wait.
2. You are correct here, We have exact same configuration regarding HSRP and RSTP.
3. If one of the 5K goes down both vPC10 and vPC11 will stay up, remember you have exact same configuration on both 5Ks. The Bandwidth will be reduced becuase some of the interfaces are not available any more.
4. On my understanding peer-link passes no data traffic, it is used to syncroinize state of the vPC membersit also passes Multicast and broadcast traffic. Unicast traffic will pass only in link failures. Do not see the peer-link as another path for traffic, remeber both switches are acting as one. If tracffic is destinated to a specific switch lets say 6513-01 connected to vPC10, traffic can come from both N5K because both have interfaces members of the vPC10.
