Help needed to spec kit for a DC

Hi Guys,

I'm hoping you can help me out. I'm trying to satisfy some DC requirements for a client for a new build they are planning. They have given me the following requirements:

Top Of Rack

1)             Fixed configuration 1 Rack Unit (RU) Form factor

2)             48 IEEE 802.3x full duplex on 100BASE-TX, and 1000BASE-T ports

3)             32 1Gbps or 10Gbps/FCoE ports

4)             Backplane capacity of a minimum of 40Gbps and a maximum of 80Gbps

5)             Internal Redundant Power Supplies

6)             Virtualisation of the data plane at layer 2

7)             Vlans

8)             IEEE 802.1Q VLAN encapsulation

9)             IEEE 802.1s MSTP

10)          IEEE 802.1w RSTP

11)          IEEE 802.3ad Link Aggregation

End Of Rack

1)             Fixed configuration Form factor

2)             Support for 1Gbps and 10Gbps Ethernet access

3)             Support for Fibre Channel and Fibre Channel over Ethernet access

4)             High Availability support for top of rack switching

5)             Internal Redundant Power Supplies

6)             Virtualisation of the data plane at layer 2

7)             Vlans

8)             IEEE 802.1Q VLAN encapsulation

9)             IEEE 802.1s MSTP

10)          IEEE 802.1w RSTP

11)          IEEE 802.3ad Link Aggregation

12)          NTP

13)          AAA

14)          SYSLOG

15)          TFTP/FTP

16)          SNMPv2 and SNMPv3

17)          SSH

18)          IEEE 802.1s MSTP

19)          IEEE 802.1w RSTP

20)          IEEE 802.1p Classification

21)          Congestion Management Features

22)          Congestion Avoidance Features

23)          Traffic Shaping Features

24)          Traffic Policing Features

Is there a 1RU switch that fits the requirements for all the above ?. I was planning on going dwn the 4948 series route but I was not aware of one that gave 10gb ethernet access. Unless I go down the 4507R+E and use the new 12 port 10GB cards, but the requirements are asking for 32 1 or 10gb ethernet access. Also, I've never configured a switch for FCOE, as it was always only our SAN guys that did that. I know Nexxus will support 10gb, but they are not considered top of rack are they ?

Any help you can give is greatly appreciated guys.

Hi Mooey,

If you are going to need FCoE, then Nexus 5000/5500 will be likely what you'd want to go with.  When combining it with the various Nexus 2000 FEX modules I think this should satisfy most of the requirements.  The 2224T and 2248T will allow 48 100/1000 ports.  The 2232P provides 32 1/10gb ports using SFP/SFP+.

Take a look at the data sheet here to look at all the SKUs to see which would fit:

http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps10110/data_sheet_c78-507093.html

However you won't find 1 RU sku here that will provide 100/1000gb and 10gig connectivity to hosts.  You'll have to choose here and design the rack with that in mind.

Also, we do have a 4948 that does have 10gig uplinks, WS-C4948-10GE.  However it doesn't do FCoE:

Take a look over it, hope it helps out
