Redundant 10g configuration

[jestinpaul67]

We need a 10G switch which is redundant without single point of failures. Can a cisco-6500 series model do this? Or a 2 x 4500X stacked model is better for around 25 x 10gbps fiber connections

Hi a single point of failure in terms of design is a single switch so a 6500 would still be a single point of failure as the chassis could go , although would be very rare for that to happen but backplanes do break as well but you have multiple line cards and dual power supply's for resiliency in 65 as well and from experience there very stable, a stacked set or a vss pair of switches would be a more hardware redundant design as there's 2 of them individual units

Just want to add, in theory, the OS in a VSS setup is a potential single point of failure.  However, if you need L2 redundancy, VSS, as Mark noted, VSS, protects you from a individual chassis failure.  As Mark also noted, chassis failure are rather rare.  A chassis with dual sups, dual power supplies and dual line cards (with individual connections to your hosts), is generally very reliable.

(NB: BTW, a Nexus pair might be a bit more reliable than a VSS pair as the member platforms OS isn't so tightly coupled.)

Hi;

It's total depend on your budget and the area where you want to install 10G Switch: There are multiple option are available as per your requirements:

1. Cisco 6500/Nexus 7700 or 9000 Series switches (Costly and can use as Core/distribution layer or Server Farm Switches).

2. Cisco 4500X Series switches (Can be used as Server Farm Switches)

3. Nexus 3500/5000 series switches (Can be used as Server Farm Switches)

In Nexus switches you can found more 10G ports.
