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.

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: 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.

Need helip for data center designing

Sir ,
I am going to design a data center where the following equipments are the
1. one router 7609
2. two core switch (WS-C6509-E)
3. two firewall (WS-C6506-E, with Firewall blade)
4. one VOICE ROUTER (CISCO2821with PVDM2-64, VWIC2-2MFT-T1/E1, PVDM2-32)
5. one Remote Access Server (AS5400XM, AS5000XM 60 Dial Port Feature Card, AS5400 Octal E1/PRI DFC card)
6. two CALLMANAGER-5.1
7. multiple no of Cisco IP Phone 7940G with Video Advantage with VT Camera II
8. one Gatekeeper (2811)
9. one Internet Router (3845)
10. one Authentication, Authorization and Accounting (AAA) System
11. one ISDN RAS 2811 with2-Port Channelized E1/T1/ISDN-PRI Network Module with video conferencing (polycom)
12. one Network Intrusion Detection/ Prevention System (NIDS)
13. one NMS
14. one Content Switch for Server Load Balancing
15. multiple Video Phone
16. lots of sever ( mail. Web, storage, etc )
17. polycom MGC 100
18. polycom 7000
also 20 no of 7206 VXR will be connect with 7609 router through lease line
so.. if u send me some link or some sample design and share some advice where I can gather some idea to design this data center in a proper way
thanks

IMO opinion the best place to start is by reading the SRNDs. They can be found here-

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.

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

This is an example I have seen and I hope that is useful to you.
Site A
Subnet: 172.16.1.0/24
Site B
Subnet:172.16.2.0/24
HeadOffice:

match access-group name Site_B
policy-map To_Spokes
class Site_A
shape average 8000000
service-policy Sub_Policy(Optional)
class Site_B
shape average 4000000
service-policy Sub_Policy(Optional)
class class-default
shape average 28000000
service-policy Sub_Policy(Optional)
Interface G0/0
Description To MPLS cloud
bandwidth 40000000
service-policy output To_Spokes
interface G0/1
Description To HeadOffice
bandwidth 40000000
service-policy output To_Spokes
It would be greatly appreciated if someone can correct this or improve it as I am still learning.
Please see the netflow graph from one of our routers using a similar policy as above.

What are share point server 2013 & Share point Designer 2013 & Office 365 & Yammer & Share point 2013 & Windows server 2008 server & Windows Server 2012 Server Data Center?

I need some clarifications.
What are share point server 2013 & Share point Designer 2013 & Office 365 & Yammer & Share point 2013 & Windows server 2008 server & Windows Server 2012 Server Data Center? How each them are related in collaboration system?
Is Share point server 2013 and Share pointer Designer 2013 available in 32bit version? If not, then how to use it in 32 bit machine by using any VMs?
Thanks
Senthil

SharePoint Server 2013:
http://office.microsoft.com/en-us/microsoft-sharepoint-collaboration-software-FX103479517.aspx
SharePoint Designer 2013:
Designer is used to develop SharePoint pages using HTML/CSS/JS as well as SharePoint Designer Workflows
Yammer:
https://about.yammer.com/
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).
SharePoint Server is 64-bit only (trial:
http://technet.microsoft.com/en-us/evalcenter/hh973397.aspx), although Designer does have a 32-bit edition (full product:
http://www.microsoft.com/en-us/download/details.aspx?id=35491).
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
machine host.

Data Center Network Design

I'm looking at a couple options for a small network in a data center. I seem to be getting hung up on all the different options. One of the options I'm looking at is end or row using both 2960Ss and Blade Center chassis switches with each physical server dual homed into a 2960, each ESX server dual homed into a blade switch and each of the switches with a Layer 2 10Gb uplink (20 total with etherchannel) to one of two 4900Ms. The 4900Ms would then have a layer 2 uplink between them to accomodate VLANs that span the access layer switches. This would be an inverted U topology. That's simple enough, and maybe that is where I should leave it, but there is the now available stacking feature of 2960s that has me wondering if there is another option available with dual homing a stack. Is there such a beast? Would it be better to stack 2960s, or even 3750s, so as to make each end of row with 2 redundant switches appear as one logical stack, and then uplink that stack to an aggregate multilayer switch such as a pair of 4900Ms? Or might that limit me to keeping VLANs within a stack and end or row?
thank you,
Bill

Hi Bill-
First, I personally would not use the 2960S for the data center, no matter the size. That switch was purposely built for user access and has some limitations. Also, depending on what you need to accomplish will determine your design. I recently did a design similar to what you are describing. We ended up putting 3750X's at the top of rack as a stack. This allows for etherchannel to your servers with both server NICs being active. From there we uplinked to a pair of 6509's in VSS. From a layer 2 point of view this was about as simple as it gets; 1 switch connected to another switch connected to a server. No spanning tree! If you can't afford stackable switches, you may want to look at routing at the top of rack. However you will lose functionality like moving VLAN's between racks, relying on server NIC software for active/passive links and the moving of VM's could be limited.

Recommended Design for WAAS in both Data center and Branch Offices

Hi All,
I need to purchase different appliances for WAAS, but before I decide what to purchase, I need to know exactly how I am going to put these devices so that I can know which one to purchase and how the designs will be.
My environment is as follows:
I have two core routers (ASR 1000 series) at Data center, two 6509 switches (expecting to insert the ACE module, and FW module) and the I have access switches which connects servers.
At the branch offices, I am expecting to place ASR1000 series also.
Now, I need to know the recommended designs for these WAAS appliances so that, I can know in advance what to purchase(i.e. how many WAAS CM, Core WAE, and Edge WAE).
Any input will highly be appreciated.
Thanks,

If you purchase the Standard Edition, your license supports:
One installation of Cisco Security Manager on one Windows-based server.
The configuration or management of 5 devices (in the Standard-5 option) or 25 devices (in the Standard-25 option). This excludes Catalyst 6500 and 7600 Series devices and their associated service modules.
If you purchase either the Standard-5 or Standard-25 license, you cannot purchase an incremental device license. Your license is fixed at either 5 or 25 devices.

Replication between 130 nodes and 1 Data Center

Hi everyone.
I have 130 database nodes (Oracle Standard Edition One) with a big distance of separation, and 1 Data Center with 3 nodes (Oracle Real Application Cluster 10g R2). The connection between nodes and datacenter is through various ISP ( WAN).
I have exactly the same model design of database in nodes and datacenter.
DataCenter is a repository of data for reporting to directors and dictate the business rules to guide all nodes.
Each node have approximately 15 machines connected with desktop application.
In other words Desktop Application with a Backend Database (node).
My idea of replication is not instantly, when a transaction commit in a node then replicate to datacenter. Also over nigth replicate images because is heavy, approximately 1 mg per image. Each image correspond to one transaction.
On the orher hand i have to replicate some data from datacenter to nodes, business rule, for example: new company names, new persons, new prohibitions, etc.
My problem is to determine th best way to replicate data through nodes to datacenter.
Please somebody could suggest me the best solution.
Thanks in advanced.

Last I checked, Streams and multi-master replication require enterprise edition databases at both ends, which rules them out for the sort of deployment you're envisioning.
If a given table will only ever be modified on nodes or on the master site, never both, you can build everything as read-only materialized views. This would probably require, though, that the server at the data center have 130 copies of each table, 1 per node. For schemas of any size, this obviously gets complicated very quickly. For asynchronous replcation to work, you'd need to schedule periodic refreshes, which assumes that you have relatively stable internet connections between the nodes and the data center.
I guess I would tend to question the utility of having so many nodes. Is it really necessary to have so many? Or could you just beef up the master and have everyone connect directly?

Data Center Standars

Dear All,
We are in the process of setting up a data center room, serving around 1500 staff in around 40 floor, my question,
Is there a standards for data centers?I mean a general guidelines to be taken into consideration while implementing, I tried the following link but didn't work due to my limited access account
http://www.cisco.com/asiapac/campaigns/brdc/resources_whitepapers.shtml#blocks_ip
If you could attach these files on the above link, I think this will help or any other Docs related to this topic.
Thanks
Mohamed

Hi Mohamed,
By the look and feel of the page you referenced I think that's a pretty old page, and hence the reason most of the documents referenced from that page are not found.
Have you tried the Design Zone for Data Centers section of CCO? This has a number of links to white papers and design guides for Data Centre Networking, Server Networking etc., and are not restricted i.e., you don't need a CCO login.

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

Hi,
In the selection screen, if you hit "Number of Hits from Infocube". it shows , how many records are selected after you have input all the values. Please check this to confirm if records really fetched before loading to PA.
If results log field is clicked in the selection screen in the transaction tscube, then it show detailed log.

Q about flexpod design guide 5.0

Hi all,
In the design guide when you setup the vswitch you only specify one network adapter for the vswitch. I added a second one in failover and reversed them depending on the order of the Vnics.
Is this correct or should I put it back to one?
I don't see how it would failover if I do.
Also I only see two veth interfaces in the port channel as this is a vic 1420 shouldn't there be 4 per fabric?
Thanks

For vSwitch implemention, i would have to let someone else step in to discuss their experiences with this setup. The N1K implementation is using mac-pinning which would be an active-active configuration. For vSwitch, you probably can have both nics active with 'Virtual Port ID' or 'Source MAC Hash' for load balancing. 'IP Hash' is a port channel and not supported on servers/blades within UCSM.
