Dual homed server to dual homed Nexus fabric extenders

I don't see anything in Cisco docs that explicitly say that this is a supported setup so I just wanted to see if anyone here has any insight on this.
Is it supported to dual home a server via etherchannel to a pair of Nexus fabric extenders that are themselves dual homed two a pair of Nexus 5Ks?
Thanks!

If i understand correctly i think what you are referring to is Enhanced vPC. See this link for details -

  • Dual-homed server to two Cat4948 switches

    Hello everyone,
    I have a picture above which I want to realize. The main point is a dual-homed server connected to two switches.
    At server OS needed to configure NIC teaming which uses LACP. But how I can do it at Catalyst 4948?
    Which technology I able to use to multi-switch etherchannel?
    If I need one more link between Cat4948, then I can do.

    The exact load sharing options available to you will probably depend on the server type / vendor. The settings are applicable to the Network Adapters but you usually use the configuration utility provided by the respective vendor. I would suggest you do a quick google search on your particular server model. An example is:

  • Dual-DMVPN Design with Dual Hubs on a single router ??

    Hi All,
    In DMVPN, in Dual-DMVPN Design with Dual Hubs , can a single router perform the role of dual hubs.
    The router has two different internet links. It is intended that when one link goes down, spokes shud connect to the same router onto the other active internet connection. Is this possible ?

    Since no one has answered yet, I'll give you the practical answer.
    You'll have issues with IPSec and static routing. "DMVPN" itself probably wouldn't have an issue, but it would depend on IPSec and routing to work.
    It is easier, by far, to put in a second router. And when you factor in your time to try to make it work (and it may not work), the second router is less expensive.

  • Different between Dual hub-dual DMVPN cloud Vs Dual hub-single DMVPN cloud

    please explain
    different between Dual hub-dual DMVPN cloud Vs Dual hub-single DMVPN cloud

    Thanks Paul, I have looked over this design guide as this was the fist place i went.  however, i cannot find a configuration example for dual hub/single cloud.
    i see the high level design and know you can do it.   but it doesnt show what the configuration would look like...unless i am just reading over it.
    Thanks

  • Is dual core faster then dual processors?

    Is dual core faster then dual processors?
    Asking for a friend who isn't sure whether to buy a MacBook Pro or a used G5.
    Main function will be video editing on Final Cut Pro.
    I'm not sure either.
    Thanks
    A

    It depends on how the application was programmed.
    If the application uses a lot of shared code or shared data, the dual core platform will be faster since the cores have a common L2 cache and this will reduce the number of memory or I/O operations. Poorly written programs won't get this benefit and will run the same on both platforms.
    Note also that the newest MBP's have a 1066 MHz processor frontside bus and also use 1066 MHz DDR3 SRAM, all of which will blow the socks off an ancient G5.
    Of course, we're assuming that the FCP version you will be running is native to the processors, in other words, a Universal Binary.

  • What's the difference between Dual Band and Simultaneous Dual Band?

    I just wondered what the difference between Dual Band and Simultaneous Dual Band was?

    Nevermind, I know now!

  • Dual band vs Simultaneous dual ban

    I am a little confused about dual band vs Simultaneous dual band and have been searching for hours and cannot find an answer.  I am looking to buy a new linksys wireless router with gigabit wired and 802.11n wireless.  I understand that Simultaneous dual band lets you use 802.11n in both 2.4Ghz and 5Ghx bands at the same time.  But if you have just a dual band (no Simultaneous) can you use 5Ghz 802.11n AND 801.11g?  I know 11g runs in 2.4Ghz, so I am afraid if I only get a dual band, and have pc's with 11g, i wont be able to run 5.0Ghz 802.11n since the radio is running only in 2.4Ghz.

     I understand 11g can't connect at 5Ghz, it only operates at 2.4Ghz.  I guess i am having a hard time explain the question.  Lets say I get the wrt320n.  I have several g devices.  I also have several n devices.  If I configure the 320n to use 5Ghz N, will i be able to use 11g at all?  Or since it ony supports one band, will I have to use 2.4Ghz N to also use g at the same time. 
    Hope that clears it up.
    Agreed the 610N would be best, but trying to save a few bucks and dont need the storage link.

  • Dual 867MHz Is now Dual 800MHz After Motherboard Replacement?

    so i replaced the motherboard on my dual 867MHz G4.
    the computer turns on now, and i did a fresh 10.4.11 install...but i noticed that it says "Dual 800" instead of "Dual 867" in my "About This Mac" now. i typed "sysctl hw.cpufrequency" in the terminal and discovered that it is actually running at 800MHz, and not 867MHz.
    so why did i lose 67MHz with a new motherboard? it was the correct motherboard...any ideas?

    G4 MDD Processor and bus speeds
    There are two classes of Processors for the Mirrored Drive Doors G4 Macs, and they do not follow the main distinction between the products -- Firewire 400 Vs. Firewire 800.
    In the Mirrored Drive Doors models, processor speed is determined by a combination of the jumpers on the processor modules and the Bus Speed of the system into which the processor is installed.
    • Install a processor intended for a faster Bus speed into a system with a slower Bus speed, and it will be clocked slower and run slower than expected. 133/167 slower.
    • Install a processor intended for a slower bus speed into a system with a faster Bus speed, and it will be clocked faster -- in most cases so fast that it will immediately crash.
    133 MHz Bus speed:
    867 MHz dual w 1 MB cache (each processor) from Fw 400 model
    1.0 GHz single w 1 MB cache from Fw 800 model
    167 MHz Bus speed:
    1.0 GHz dual w 1 MB cache (each processor) from Fw 400 model
    1.25 GHz dual w 2 MB cache (each processor) from Fw 400 model
    1.25 GHz dual w 1 MB cache (each processor) from Fw 800 model

  • Dual 867mhz MDD G4 & Dual 1Ghz G4 Quicksilver: Near Perfect Installation

    I installed the family pack on both my desktop G4 towers (Dual 867mhz MDD G4 & Dual 1Ghz G4 Quicksilver) and had almost ZERO problems.
    I opted to upgrade my OS X 10.4.10 systems.
    Both installations (upgrades) were without a problem, except for one minor keychain glitch:
    MDD Dual 867mhz G4: After installation and restart, the keychain seemed to have forgotten my passwords for my POP email and my iChat (AIM) accounts. I simply cleared the keychain (as prompted) and re-entered the passwords (opted to save them) and all is well.
    Quicksilver Dual 1ghz G4: No keychain issue. Passwords were retained just fine.
    Every piece of email, settings, music, files, folders, apps, etc were all retained just fine on both computers.
    All my Adobe CS2 suite apps, MS Apps are just fine.....as does my Final Cut Pro software.
    The only software that "broke" was GOOGLE EARTH. I simply just downloaded the latest version and all is well again.
    Approx. Install time: 1hr.
    Note: If your computer stalls on a blue screen (my computers did this on TIGER install), let them go. More than likely it's "finishing" the installation and probably cataloging the hard drive for Spotlight.
    This Leopard OS Rocks! I can't wait til they fine tune it with a 10.5.1 update release

    I put Leopard on a Dual 800 and a Dual 400.
    Leopard pushes the limits of the 400. The 800 runs pretty well.
    I mean it is slower in some places, but I assume that will be fixed in updates.
    (for instance... my cursor is sticking to links in firefox and it kills my CPU usage)
    Everything else works great.

  • What to keep? - Dual 1.42 or Dual Sonnet 1.83 - RAM: 4x512MB or 2x1GB

    Im looking for some insight - I have both the Apple Dual 1.42 and Dual Sonnet MDX 1.8Ghz Cards for my MDD. Im sure that everyone already knows the specs of these 2 cards. I Use mainly music editing and gaming softare on my machine. Im just trying to figure out what is the fastest card, and is there a solid benchmark program that can give me a definitive answer?
    X-bench CPU Avg. scores are around: 77 for the 1.42 and 95 for the 1.8, but Im not sure if i trust X-bench scores, they seem inconsistent. Geekbench scores the 1.42 @ 1200+, and the 1.8 @ 1500+, So now it looks like the the Sonnet card is the fastest..... Now when I run Cinebench, the dual 1.42 always has the lowest numerical score in all tests compaired to the dual 1.8, which im guessing is the L3 in the 1.42 is doing this. What can I trust? What numbers should I be looking at? Is there another Benchmark program that is better?
    Also any ideas on the impact in speed by using 4 x 512mb Ram Sticks or 2 x 1 Gb sticks (in dual channel of course)?
    All thoughts welcome, thanks!

    Hi-
    Geekbench and Cinebench are completely trustworthy.
    The reason the dual 1.42 does better in Cinebench is due to the L3 cache.
    In Geekbench, it is due to the higher clock speed of the Sonnet.
    Your question as to which is better is only answered with "it depends".
    Benchmarks only provide a point of comparison.
    Real world use determines the reality.
    For gaming, graphics intensive and video applications, the dual 1.42 is the better choice.
    For general computer use, without graphics intensive work, the Sonnet is probably better.
    There should be no difference in 4x 512MB or 2x 1GB DIMMs.
    Unlike PC's, Mac firmware controls the timing and speed of the RAM.
    Unlike G5 and Mac Pro machines, matched pairs and full channels make no difference in the G4.
    If there were any difference, it wouldn't be one that you would see/feel.....

  • Dell Servers with Nexus 7000 + Nexus 2000 extenders

    << Original post by smunzani. Answered by Robert. Moving from Document section to Discussions>>
    Team,
    I would like to use some of the existing Dell Servers for new network design of Nexus 7000 + Nexus 2000 extenders. What are my options for FEC to the hosts? All references of M81KR I found on CCO are related to UCS product only.
    What's best option for following setup?
    N7K(Aggregation Layer) -- N2K(Extenders) -- Dell servers
    Need 10G to the servers due to dense population of the VMs. The customer is not up for dumping recently purchased dell boxes in favor of UCS. Customer VMware license is Enterprise Edition.
    Thanks in advance.

    To answer your question, the M81KR-VIC is a Mezz card for UCS blades only.  For Cisco rack there is a PCIe version which is called the P81.  These are both made for Cisco servers only due to the integration with server management and virtual interface functionality.

  • Monitoring traffic between UCS fabric extenders and fabric interconnect?

    What is the best way to monitor the traffic between UCS fabric extenders (chassis) and fabric interconnect? Specifically I am looking for parameters to keep an eye on to determine when we may need to move from 2 links per fabric extender to 4 to handle greater IO needs.
    Thanks.
    - Klaus

    One way you could monitor usage is by looking at the interface stats just as you would for any switch uplink.
    Connect to the Cluster CLI
    connect NXOS
    Look at the input/output rate of your Server Uplink interfaces.
    In my example I'm using fixed ports 1 through 4 on my FI's connecting to the IOM of the Chassis.
    UCS-A(nxos)# show int eth1/1-4 | include rate
      30 seconds input rate 17114328 bits/sec, 1089 packets/sec
      30 seconds output rate 8777736 bits/sec, 693 packets/sec
        input rate 5.07 Mbps, 198 pps; output rate 1.03 Mbps, 99 pps
      30 seconds input rate 2376 bits/sec, 0 packets/sec
      30 seconds output rate 1584 bits/sec, 2 packets/sec
        input rate 1.58 Kbps, 0 pps; output rate 1.58 Kbps, 3 pps
      30 seconds input rate 2376 bits/sec, 0 packets/sec
      30 seconds output rate 31680 bits/sec, 20 packets/sec
        input rate 1.58 Kbps, 0 pps; output rate 30.89 Kbps, 18 pps
      30 seconds input rate 2376 bits/sec, 0 packets/sec
      30 seconds output rate 1584 bits/sec, 1 packets/sec
        input rate 1.58 Kbps, 0 pps; output rate 1.58 Kbps, 3 pps
    If you notice your two links pushing near 10G consistently, it might be time to add another 2 link.
    Other than this you can use SNMP to log the stats and look based on daily/weekly/monthly usage.

  • Define Primary IP on dual homed server

    Hi
    I have a server with 2 NIC i different VLAN's, lets say:
    Hostname: Server1
    Domain: domain.local
    NIC1 IP: 10.10.10.1 (Domain VLAN)
    NIC2 IP: 10.10.11.1 (DMZ VLAN)
    When I'm logged on this server and I do "ping server1.domain.local -4" the answer comes from IP 10.10.11.1 But I need the answer to come from 10.10.10.1
    I have disabled that NIC2 registres in DNS, and disabled LMHOSTS and NetBIOS over TCP.
    I have been to the advanced menu in "network connections" and arranged so the domain net NIC is on top, and I have restarted.
    How can I define IP 10.10.10.1 to be the IP address it answers on, when server1.domain.local is trying to be reached, from the server itself?
    Regards Lars

    Hi Lars,
    According to your description, the goal is when we use ping server1.domain.local command in the server, we can receive the responses from 10.10.10.1.
    In order to achieve this goal, we could add a entry (10.10.10.1    server1.domain.local) in the hosts file.
    Host name resolution generally uses the following sequence:
    The client checks to see if the name queried is its own.
    The client then searches a local Hosts file, a list of IP address and names stored on the local computer.
    Domain Name System (DNS) servers are queried.
    If the name is still not resolved, NetBIOS name resolution sequence is used as a backup. This order can be changed by configuring the NetBIOS node type of the client.
    So if there is an entry for a domain name in the Hosts file, then the server will not attempt to query DNS servers for that name. Instead, the IP address that is configured in the Hosts file will be used.
    In addition, if we ping server1 from the other client in the domain vlan, we will receive response from the 10.10.10.1. And if we ping server1 from the 10.10.11.x network segment, we will receive response from the 10.10.11.1.
    Best Regards,
    Tina

  • Server 2012 Dual Monitor Issue - Can't Get it to work properly.

    I have a HP Proliant ML310e that runs Server 2012 R2. It came with an on-board VGA graphics adapter, that was using a Microsoft Basic Display Adapter driver and working fine.
    Needing to run dual monitors, I contacted HP and purchased a Nvida K2000 PCIE graphics card. I installed it using their latest drivers and rebooted, making sure that the new PCIE card was enabled in the BIOS.
    While booting, the server actually now displayed on the new 'second' monitor connected to the newly installed Nvida card. When I actually logged in and went into the display properties, it was only detecting the new display - I couldn't even force detect
    the original display.
    Also, when I go into device Manger, it now only shows the Nvidia graphics adapter - no longer shows that the Microsoft Basic Display Adapter is present.
    Any advice on how to get dual monitors to work on Server 2012. I did try the Windows/P Projector display, but that did nothing.
    Thanks,

    Hi,
    You should check your BIOS settings - some motherboard will disable onboard display card once a PCI(E) card is plugged in. This is a hardware settings issue. If  HP support is available, ask them for detailed configuration steps.
