Does the Nexus 5648Q support nexus 2348UPQ in FC fex mode?

[Hele Du]

Hi Experts,

As Far as I know, only the 5672UP can support native FC, which can directly connected to a FC host.

Deos the N2348UPQ must directly connected to 5672UP if running in FC FEX mode?

The following  is guideline in configuration guide.

"The FC ports on Nexus 2348UPQ are supported only on the Cisco Nexus 5600 switches."

I would like to double check if I am using a N5648Q, it going to be working.

Thanks.

Are you referring to Fibre Channel or FCoE?

The Nexus 5648Q will work with the N2348UPQ.

Please see the following 

he Cisco Nexus 2348UPQ fabric extender (Figure 2) is a general-purpose unified port - capable (currently, Fibre Channel functions are supported only in Nexus 5600 since 7.3(0) N1 (1)) 1/10 Gigabit Ethernet fabric extender for workloads such as large-volume databases, distributed storage, and video editing

Have a great day...

Thanks, rnmcgee,

If so , does the storage license on N5K means per port on 5k or on FEX?

[Rick1776]

The FEX will be considered part of the 5K so depending on what license you have. For example if you has 20 SAN license that means 20 ports between the 5K and 2K.

Here are your options...

N56-12Q-P-SSK9        

Nexus 5600 Promo Storage Lic, 12-ports 40G or 48-ports 10G More

N56-20P-SSK9

Nexus 5696 20 Port Storage License for the UP LEM

N56-48Q-P-SSK9        

Nexus 5600 Promo Storage Lic, 48-ports 40G or 192-ports 10G Nexus 5600 Promo Storage

Also remember the 2348UPQ only support 24 Fibre Channel ports...

The Cisco Nexus 2348UPQ fabric extender (Figure 2) is a general-purpose unified port - capable (currently, Fibre Channel functions are supported only in Nexus 5600 since 7.3(0) N1 (1)) 1/10 Gigabit Ethernet fabric extender for workloads such as large-volume databases, distributed storage, and video editing. The Cisco Nexus 2348UPQ supports 48 x 1- and 10-Gbps host unified ports as well as up to six 40-Gbps uplink ports to the parent switch. The 40-Gbps uplinks support BiDi optics for simple connectivity using your existing cable plan. The unified ports provide connectivity to 2-, 4-, 8-, and 16-Gbps Fibre Channel (24 ports for 16 Gbps) as well as 1 and 10 Gigabit Ethernet and FCoE connectivity options (currently, Fibre Channel functions are supported only in hardware). The Cisco Nexus 2348UPQ has a deep 32-MB shared buffer that helps increase performance, and it supports FCoE and Data Center Bridging (DCB) network technologies, which boost the reliability, efficiency, and scalability of Ethernet networks. These features provide support for multiple traffic classes over a lossless Ethernet fabric, enabling consolidation of LAN, SAN, and cluster environments.

How much port license count will occupy if I am using 16G FC, just one or two?

[Rick1776]

Just one.

Hi rnmcgee,

Sorry for late response.

Thank you so much.
