Data Center Design: Nexus 7K with VDC-core/VDC-agg model

Dear all,
I'm doing with a collapsed VDC-core/VDC-agg model on the same chassis with 2 Redundant Cisco Nexus 7010 and a pair of Cisco 6509 used as a Service Chassis without VSS. Each VDC Core have redundant link to 2 PE based on Cisco 7606.
After reading many design document of Cisco, I'm asking what is the need of a Core Layer in a Data Center especially if it is small or medium size with only 1 aggregation layer and dedicated for a Virtualized Multi-Tenanted environement? What is driving to have a core layer?
Thanx

If your data center is small enough to not require a core, then its fine to run with a collapsed core (distribution + core as the same device). For a redundant design you need to uplink all your distribution switches to each of your cores. If you have no cores, then you need full mess at your distribution layer (for full redundancy).
Lets say you have only 4 distribution pairs...so 8 switches For full redundancy each one needs uplink to each other. This means you need 28 total ports used to connect all the switches together (n(n-1)/2). Thats also assuming 1 link to each device. However if you had redundant cores, the number of links used for uplinks reduces to 21 total links (this includes links between each distribution switch in a site, and link between the two cores). So here you see your only saving 7 links. Here your not gaining much by adding a core.
However if you have 12 distribution pairs...so 24 switches. Full redundancy means you have 276 links dedicated for this. If you add a core, this drops to 61 links. Here you see the payoff.

Data Center Design

I am looking for a good article about data center design. I need some information about requirements for topics such temperature control, power, security, ventilation, etc.

The practice of System and Network administration is a great resource for the "other" things that make a data center successful.

Another great resource that you should reference is your local power company. PG&E for example will consult with you, and sometimes pay for upgrades to lower your power consumption.
Here is an article that talks about that in general -

Please shed some light on Data Center design

Hi,
    I want you guys to recommend what the design should be. I'm familiar with HP blade system. Let me clarify the existing device.
1. HP Blade with Flex Fabric. It supports FCOE.
2. MDS SAN switch for the storage
3. Network Switch for IP network.
4. HP Storage.
    HP Blade has 2 interface types for IP Network(Network Switch) and Fiberchannel(SAN).
   What is the benifit for using Nexus switch and FCOE for my exising devices. What should be a new design with Nexus switch? Please guide me ideas.

Toshi

Hi, Toshi:
Most of these chat boards have become quite boring. Troubleshooting OSPF LSA problems is old news. But I do pop my head in every now and then. Also, there are so many other companies out there doing exciting things in the data center. You have Dell, Brocade, Arista, Juniper, etc. So one runs the risk of developing a myopic view of the world of IT by lingering around this board for too long.
If you want to use the new B22 FEX for the HP c7000 blade chassis, you certainly can. That means the Nexus will receive the FCoE traffic and leverage its FCF functionality; either separate the Ethernet and FC traffic there, or create a VE-port instantiation with another FCF for multihop deployments. Good luck fighting the SAN team with that one! Another aspect of using the HP B22 is the fact that the FEX is largely plug and play, so you dont have to manage the Flex Fabric switches.

Data center design! What is ACE

Hi Everyone,
We are planning to have a datacenter. decided to buy 2 core 6500 series switches. what exactly is ACE? i understand it does loadbalancing. but then why wd not one use CSS instead on ACE. if we use ACE , can we eliminate the need of FWSM module. i read ACE has lots of security features. also it does web caching.. i may be wrong here.
So if we only have ACE in 6500, do we still need FWSM and some web caching engine (WASS). please also let me know some important features of ACE-Thanks

The ACE module is a loadbalancer that should eventually replace the CSS and CSM.
It comes with some firewall features but not all of them. Some users have enough FW features on the ACE module so they don't need the FWSM.
Others still need the FWSM.
Depends on what you need.
Finally, the ACE module does not come with caching option. Only the ACE Appliance - c4710 - has the caching and optimization features.
Gilles.

Data Center Fundamentals Book?

So we're building a new data center from scratch mainly with Nexus 5548s, UCS 6248UPs, UCS 5108s, ACE 4710s and NetApp 3240 filer.
I have very basic experience with Data Center's network fundamentals and infrastructure so I'm going to do some homework here.
I've found the book I've mentioned in title which is very close to what I want but it's a 2003 book. Dose this still cover what I need?
I also found a new book called "Cisco Unified Computing System (UCS) (Data Center): A Complete Reference Guide to the Cisco Data Center Virtualization Server Architecture". Does this covers Data Center's network fundamentals and infrastructure as well.
Even I found this design document: http://www.cisco.com/en/US/docs/solutions/Enterprise/Data_Center/DC_Infra2_5/DCI_SRND_2_5_book.html
So where should I start from? Which one do you recommend? Is there any non-Cisco press books that you recommend?
Thanks

Deploying Cisco Overlay Transport Virtualization (OTV) in Data Center Networks

Hi Dennis,
    All those Layer 2 extension technologies require STP to be extended between Data Centers if you need to have multiple paths between Data Centers. OTV does not extend STP rather it has its own mechanism (AED election) to avoid loop when multiple paths are enabled. It means any STP control plane issue, we don't carry to the other Data Center.
    OTV natively suppresses Unknown Unicast Flooding across the OTV overlay. Unknown unicast flooding is a painful problem in layer 2 network and difficult to troubleshoot to identify the root cause if you don't have proper network monitoring tool.
   It has ARP optimization which eliminates flooding ARP packets across Data Center by responding locally with cached ARP messages. One of the common issues I have seen in Data Center is some server or device in the network sends continuous ARP packets which hits Control plane in the Aggregation layer which in turn causes network connectivity issue.
The above three points proves the Layer 2 domain isolation between data centers. If you have redundant Data Centers with Layer 2 extended without OTV, the above explained layer 2 issue which happens in one Data Center carries the same failure to the second data center which creates the question of what is the point of having two different Data Centers if we can not isolate the failure domain.
OTV natively supports HSRP localization with few command lines. This is a very important requirement in building Active/Active Data Center.
Even though your question is related to L2TP, OTV deserves the comparison with VPLS and those comparison will also be applicable for L2TP. The below link explains in detail...

Hi Ramses,
I have dozen questions but will try to restrain myself and start with the most important ones :)
1. Can cables between IOM and FI be configured in a port-channel? Let me clarify what I"m trying to achieve: if I have only one chassis with only one B200M3 blade inside, will the 2208 IOM and FI6296 allow me to achieve more than 10Gbps throughput between the blade and the Nexus 5k? Of course, we are talking here about clean ethernet environment.
B200M3 --- IOM2208 --- 4 links --- FI6296 --- port-channel (4 links) --- Nexus5548
2. Is it possible to view/measure throughput for Fibre Channel interfaces?
3. Here is one about FlexPod: I know that in case of vBlock there is the company that delivers fully preconfigured system and offers one universal support point so customer don't have to call Cisco or VMware or storage supports separately. What I don't know is how it works for FlexPod. Before you answer that you are not sales guy, let me ask you more technical questions: Is FlexPod Cisco product or is NetApp product or this is just a concept developed by two companies that should be embraced by various Cisco/NetApp partners? As you obviously support Datacenter solutions, if customer/partner calls you with are FlexPod related problem, does it matter for you, from support side, if you are troubleshooting fully compliant FlexPod system or you'll provide same level of support even is the system is customized (not 100% FlexPod environment)?
4. When talking about vCenter, can you share your opinion about following: what is the most important reason to create the cluster and what will be the most important limitation?
5. I know that NetApp has feature called Rapid Clones that allows faster cloning than what vCenter offers. Any chance you can compare the two? I remember that NetApp option should be much faster but didn't understand what is actually happening during the cloning process and I'm hoping you can clarify this? Maybe a quick hint here: seems to me it will be helpful if I could understand the traffic path that is used in each case. Also, it will be nice to know if Vblock (i.e. EMC) offers similar feature and how it is called.
6. Can I connect Nexus 2000 to the FI6xxx?
7. Is vBlock utilizing Fabric Failover? Seems to me not and would like to hear your opinion why.
Thanks for providing us this opportunity to talk about this great topic.

Ask the Expert: Scaling Data Center Networks with Cisco FabricPath

With Hatim Badr and Iqbal Syed
Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about the Cisco FabricPath with Cisco technical support experts Hatim Badr and Iqbal Syed. Cisco FabricPath is a Cisco NX-OS Software innovation combining the plug-and-play simplicity of Ethernet with the reliability and scalability of Layer 3 routing. Cisco FabricPath uses many of the best characteristics of traditional Layer 2 and Layer 3 technologies, combining them into a new control-plane and data-plane implementation that combines the immediately operational "plug-and-play" deployment model of a bridged spanning-tree environment with the stability, re-convergence characteristics, and ability to use multiple parallel paths typical of a Layer 3 routed environment. The result is a scalable, flexible, and highly available Ethernet fabric suitable for even the most demanding data center environments. Using FabricPath, you can build highly scalable Layer 2 multipath networks without the Spanning Tree Protocol. Such networks are particularly suitable for large virtualization deployments, private clouds, and high-performance computing (HPC) environments.
This event will focus on technical support questions related to the benefits of Cisco FabricPath over STP or VPC based architectures, design options with FabricPath, migration to FabricPath from STP/VPC based networks and FabricPath design and implementation best practices.
Hatim Badr is a Solutions Architect for Cisco Advanced Services in Toronto, where he supports Cisco customers across Canada as a specialist in Data Center architecture, design, and optimization projects. He has more than 12 years of experience in the networking industry. He holds CCIE (#14847) in Routing & Switching, CCDP and Cisco Data Center certifications.
Iqbal Syed is a Technical Marketing Engineer for the Cisco Nexus 7000 Series of switches. He is responsible for product road-mapping and marketing the Nexus 7000 line of products with a focus on L2 technologies such as VPC & Cisco FabricPath and also helps customers with DC design and training. He also focuses on SP customers worldwide and helps promote N7K business within different SP segments. Syed has been with Cisco for more than 10 years, which includes experience in Cisco Advanced Services and the Cisco Technical Assistance Center. His experience ranges from reactive technical support to proactive engineering, design, and optimization. He holds CCIE (#24192) in Routing & Switching, CCDP, Cisco Data Center, and TOGAF (v9) certifications.

Hi Sarah,
Thank you for your question.
Spanning Tree Protocol is used to build a loop-free topology. Although Spanning Tree Protocol serves a critical function in these Layer 2 networks, it is also frequently the cause of a variety of problems, both operational and architectural.
One important aspect of Spanning Tree Protocol behavior is its inability to use parallel forwarding paths. Spanning Tree Protocol forms a forwarding tree, rooted at a single device, along which all data-plane traffic must flow. The addition of parallel paths serves as a redundancy mechanism, but adding more than one such path has little benefit because Spanning Tree Protocol blocks any additional paths
In addition, rooting the forwarding path at a single device results in suboptimal forwarding paths, as shown below, Although a direct connection may exist, it cannot be used because only one active forwarding path is allowed.
Virtual PortChannel (vPC) technology partially mitigates the limitations of Spanning Tree Protocol. vPC allows a single Ethernet device to connect simultaneously to two discrete Cisco Nexus switches while treating these parallel connections as a single logical PortChannel interface. The result is active-active forwarding paths and the removal of Spanning Tree Protocol blocked links, delivering an effective way to use two parallel paths in the typical Layer 2 topologies used with Spanning Tree Protocol.
vPC provides several benefits over a standard Spanning Tree Protocol such as elimination of blocker ports and both vPC switches can behave as active default gateway for first-hop redundancy protocols such as Hot Standby Router Protocol (HSRP): that is, traffic can be routed by either vPC peer switch.
At the same time, however, many of the overall design constraints of a Spanning Tree Protocol network remain even when you deploy vPC such as
1.     Although vPC provides active-active forwarding, only two active parallel paths are possible.
2.     vPC offers no means by which VLANs can be extended, a critical limitation of traditional Spanning Tree Protocol designs.
With Cisco FabricPath, you can create a flexible Ethernet fabric that eliminates many of the constraints of Spanning Tree Protocol. At the control plane, Cisco FabricPath uses a Shortest-Path First (SPF) routing protocol to determine reachability and selects the best path or paths to any given destination in the Cisco FabricPath domain. In addition, the Cisco FabricPath data plane introduces capabilities that help ensure that the network remains stable, and it provides scalable, hardware-based learning and forwarding capabilities not bound by software or CPU capacity.
Benefits of deploying an Ethernet fabric based on Cisco FabricPath include:
• Simplicity, reducing operating expenses
– Cisco FabricPath is extremely simple to configure. In fact, the only necessary configuration consists of distinguishing the core ports, which link the switches, from the edge ports, where end devices are attached. There is no need to tune any parameter to get an optimal configuration, and switch addresses are assigned automatically.
– A single control protocol is used for unicast forwarding, multicast forwarding, and VLAN pruning. The Cisco FabricPath solution requires less combined configuration than an equivalent Spanning Tree Protocol-based network, further reducing the overall management cost.
– A device that does not support Cisco FabricPath can be attached redundantly to two separate Cisco FabricPath bridges with enhanced virtual PortChannel (vPC+) technology, providing an easy migration path. Just like vPC, vPC+ relies on PortChannel technology to provide multipathing and redundancy without resorting to Spanning Tree Protocol.
Scalability based on proven technology
– Cisco FabricPath uses a control protocol built on top of the powerful Intermediate System-to-Intermediate System (IS-IS) routing protocol, an industry standard that provides fast convergence and that has been proven to scale up to the largest service provider environments. Nevertheless, no specific knowledge of IS-IS is required in order to operate a Cisco FabricPath network.
– Loop prevention and mitigation is available in the data plane, helping ensure safe forwarding that cannot be matched by any transparent bridging technology. The Cisco FabricPath frames include a time-to-live (TTL) field similar to the one used in IP, and a Reverse Path Forwarding (RPF) check is also applied.
• Efficiency and high performance
– Because equal-cost multipath (ECMP) can be used the data plane, the network can use all the links available between any two devices. The first-generation hardware supporting Cisco FabricPath can perform 16-way ECMP, which, when combined with 16-port 10-Gbps port channels, represents a potential bandwidth of 2.56 terabits per second (Tbps) between switches.
– Frames are forwarded along the shortest path to their destination, reducing the latency of the exchanges between end stations compared to a spanning tree-based solution.
    – MAC addresses are learned selectively at the edge, allowing to scale the network beyond the limits of the MAC addr

Data Center Aggregation/Access SW Nexus

i have a design scinario for backup email data center, some difficulties faced when trying to match the requirements to Boxes.
the design required a Nexus 5548UP with addition to 2x Virtualized Data center switches, also it required 12 x CPU license for VM Virtual Network Switch. i suggested to add Nexus 1000 series but the consern is can i use it without adding Nexus 2k . if i have to use N2k and N1k what is the best configuration scinario?

Hi Shakeeb,
I don't understand your question very well, but I will try clarify some points.
You don't need a Nexus 2000 if you have enough ports available in your Nexus 5500, even if you will use nexus 1000v.
In this scenario what I recommend to you is connect the both Nexus 5548 each other and create a vpc with upstreams routers and downstream blades and storage.

URGENT: QoS Design on Data Center MPLS - MediaNet Question...

Hello,
I am posting this in hopes I can get some guidance from anyone who has done this in the field. We have a large enterprise customer with 21 sites all around the world, they have Verizon MPLS and are experiencing QoS related issues on their WAN regarding Video/Voice. We have proposed remediating their network acccording to the Enterprise QoS SRND 3.3 and the new MediaNet SRND to account for Video and TP QoS (
http://www.cisco.com/en/US/docs/solutions/Enterprise/WAN_and_MAN/QoS_SRND_40/QoSCampus_40.html )
Here is the problem/question that was proposed in our presales meeting and I honestly don't know where to look for an answer... I am not asking for anyone to design a solution for me, just merely point me in the right direction:
The Data Center has a ~40MB MPLS Connection ( full mesh ) into the cloud ( Verizon )
Site A has a 8MB connection
Site B has a 4MB connection
I know on the Service policy and the interfaces at SiteA and SiteB I can assign "Bandwidth xxxx" and use ~95% of the bandwidth to do queuing and shaping/policing ect. I am not concerned with SiteA and SiteB, that I think I can handle...
Question was posed from the customer, "How can we ensure at the DataCenter level the 40MB MPLS is "chopped" up so that only 8MB of the total speed goes to SiteA ALONG with an attached QoS policy designed for that specific site, as well as ensure only 4MB goes to SiteB with an attached QoS policy.
So I am looking for a way to allocate bandwith per site on the DC 40MB connection going into the cloud ( so that SiteB cannot use more than 4MB ) and attach a MediaNet specific QoS Service policy to that site. The customer does not have seperate MPLS circuits for each site, they all come into the DC on 40MB shared ethernet connection ( no VC, or dedicated circuits to other sites ).
Any thoughts on if this is possible?
Thanks!
Alex

It would be greatly appreciated if someone can correct this or improve it as I am still learning.

Layer 3 config design on Nexus 5500 with Fabric Path

I trying to Network deisgn for new data Center , i am new to DataCenter desgin, i attached the network diagram
i would like to know if can configure my layer3 on 5500 and configure Fabric path to uplink switch
please help give your suggestions on this design

You can configure layer-3 on the 5500 series, but you need to install a daughter cards in each 5500.

Windows Server is Windows, but the Server OS. SharePoint runs on top of supported Windows Servers editions (see http://technet.microsoft.com/en-us/library/cc262485.aspx).

You will need the capability to run 64bit VMs. Minimum recommended all-in-one VM for SharePoint is to allocate 24GB of RAM, but you can get away with as little as 12GB (I wouldn't go below that). Because of this, it generally rules out 32bit OSes as a virtual

Nexus 5K - Data Center to Data Center

Hi All,
A scenario was recently presented to me that involved connecting two SANs between two Data Centers. One of the Data Centers is existing and utilizes Nexus 5K switches while the other Data Center will be greenfield and is currently just a shell.
From what I've been reading the Nexus 5K does not support FCIP and I have some concerns regarding the feasibility to perform SAN to SAN over a Service Providers WDM infrastructure; mainly due to cost. More reading suggested that this could not be done with FCoE.
Just wanted to pick everyones brain regarding what solutions are available to interconnect two SANs between Data Centers. The solution would involve using a Service Provider, Ethernet and WDM services are available to both locations.

You can add a pair of MDS9222i in the middle. This will take care of FCIP, DWDM traffic.
