• Cisco Nexus 1000V Virtual Switch Module investment series in the Cisco Unified Computing System

  Hi all
  I read an article by Cisco entitled "Best practices in Deploying Cisco Nexus 1000V Switches Cisco UCS B and C Series series Cisco UCS Manager servers" http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps9902/white_paper_c11-558242.html

  A lot of excellent information, but the section that intrigues me, has to do with the implementation of module of the VSM in the UCS. The article lists 4 options in order of preference, but does not provide details or the reasons underlying the recommendations. The options are the following:

  ============================================================================================================================================================
  Option 1: VSM external to the Cisco Unified Computing System on the Cisco Nexus 1010

  In this scenario, the virtual environment management operations is accomplished in a method identical to existing environments not virtualized. With multiple instances on the Nexus 1010 VSM, multiple vCenter data centers can be supported.
  ============================================================================================================================================================

  Option 2: VSM outside the Cisco Unified Computing System on the Cisco Nexus 1000V series MEC

  This model allows to centralize the management of virtual infrastructure, and proved to be very stable...
  ============================================================================================================================================================

  Option 3: VSM Outside the Cisco Unified Computing System on the VMware vSwitch

  This model allows to isolate managed devices, and it migrates to the model of the device of the unit of Services virtual Cisco Nexus 1010. A possible concern here is the management and the operational model of the network between the MSM and VEM devices links.
  ============================================================================================================================================================

  Option 4: VSM Inside the Cisco Unified Computing System on the VMware vSwitch

  This model was also stable in test deployments. A possible concern here is the management and the operational model of the network links between the MSM and VEM devices and switching infrastructure have doubles in your Cisco Unified Computing System.
  ============================================================================================================================================================

  As a beginner for both 100V Nexus and UCS, I hope someone can help me understand the configuration of these options and equally important to provide a more detailed explanation of each of the options and the resoning behind preferences (pro advantages and disadvantages).

  Thank you

  No, they are different products. vASA will be a virtual version of our ASA device.

  ASA is a complete recommended firewall.

• Why is - that someone would need Cisco Nexus 1000v when DvSwitch is so Kool

  Why is - that someone would need Cisco Nexus 1000v when DvSwitch is so Kool

  Or is it something that DvSwitch cannot always do that Cisco Nexus 1KV possible?

  Use of 1kV Nexus are clear enough, if you want to segregation, the advanced settings of COS, use Cisco VSG, etc. etc., you must use Nexus 1kV. But if you do not use one of these, why would you pay more money to use a Nexus 1kV, while you can use dvSwitch, giving you more or less the same basic features. After all, the 1kV has been developed using the dvSwitch framework.

• Cisco Nexus 1000v switch

  Hi, I have 2 questions about the Switch Cisco Nexus 1000v.

  First of all, why use it rather than the standard vswitch distributed?

  Second, if an environment currently works using distributed vswitches, what are the impacts and the problems likely to introduce a Switch Cisco Nexus 1000v? Is there a process for the upgrade?

  See you soon

  Here is a comparison for the most up-to-date between the optioins network:

  http://www.Cisco.com/en/us/prod/collateral/switches/ps9441/ps9902/solution_overview_c22-526262.PDF

  The great driver with most of the people running the 1000v I talked to is give visibility to the network team and streamlining changes made to the virtual network environment. In a great organazation with a network operations team, they will create an IVR to route a new VLAN, and then create the new VLAN on all switches distribution and access in the area of layer 2, just 1000v allows them to move forward and it create on the hypervisor using a set of commands that they already know.

• help required for cisco nexus 1000v

  Hello

  I have three esxi host in my environment and I want to integrate these hosts with cisco nexus 1000v switch.

  I installed vsm on host1 and adding the remaining host via vsm Update Manager. exchanges I have already create in SMV shown in the welcome that I've added to the vsm, but the port group is not shown on the host1 esx on which I have installed vsm, should I also add the host that contains MSM in the cisco nexus switch?

  I want to say that I have installed the MEC on any army three esxi. is it good?

  Hi Mohsin,

  Where did you read that? In the past, we have added the guests, including one who executes the VSM. Usually run us both VSMs (primamry and secondary) and add anti rules affinity so that the two VSMs are on different hosts. I'm not a person CISCO, but having worked with CISCO engineers, we had no problem with what you have just mentioned. It would really be a waste of host in my opinion. I don't see why this could be a problem... As long as you have all your trade (PGs for your packages VSM etc etc) in place, you should be able to add all hosts in my experience.

• Restoration of Cisco Nexus 1000V - Host-ID fingerprint

  Someone find some information about how to restore a Cisco Nexus 1000V?

  The license is the result of a fingerprint of the identifier of the VSM. In case we lose the VM with VSM or host ESX Server must be reinstalled, this print is different. So that would mean the licensekey need, it's be regenerated.

  Has anyone found information on it?

  Tom

  Q: can you a VSM manage it's own VEM?

  R: Yes

  Can Q: you a VSM vMotion?

  A: we do not recommend it.

• Cisco Nexus 1000V - DMZ - ARP

  Hello

  Thanks for reading.

  I have a virtual (VM1) connected to a Nexus 1000V distributed switch.  The willing 1000V of a connection to our DMZ (physically, an interface on our Cisco ASA 5520) which has 3 other virtual machines that are used successfully to the top in the demilitarized zone.  The problem is that a SHOW on the SAA ARP shows the other VM addresses MAC but not VM1.

  The properties for all the VMS (including VM1) participating in the demilitarized zone are the same:

  • Tag network
  • VLAN ID
  • Port group
  • State - link up
  • DirectPath i/o - inactive "path Direct I/O has been explicitly disabled for this port.

  The only important difference between VM1 and the others is that they are multihomed agents and have one foot in our private network.  I think that the absence of a private IP VM1 is not the source of the problem.  All virtual machines recognized as directly connected to the ASA (except VM1).

  Have you ever seen this kind of thing before?

  Thanks again for reading!

  Bob

  The systems team:

  1. Rebuilt the virtual machine
  2. Moved to another cluster
  3. Configured for DMZ interface

  Something that they got the visible VM to the FW.

• Upgrade to vCenter 4.0 with Cisco Nexus 1000v installed

  Hi all

  We have vCenter 4.0 and ESX 4.0 servers and we want to upgrade to version 4.1. But also Nexus 1000v installed on the ESX Server and vCenter.i found VMware KB which is http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1024641 . But only the ESX Server upgrade is explained on this KB, vCenter quid?  Our vcenter 4.0 is installed on Windows 2003 64-bit with 64-bit SQL 2005.

  We can upgrade vcenter with Nexsus plugin 1000v installed upgrading on-site without problem? And how to proceed? What are the effects of the plugin Nexus1000v installed on the server vcenter during update?

  Nexus1000v 4.0. (version 4).sv1(3a) has been installed on the ESX servers.

  Concerning

  Mecyon,

  Upgrading vSphere 4.0-> 4.1 you must update the software VEM (.vib) also.  The plugin for vCenter won't change, it won't be anything on your VSM (s).  The only thing you should update is the MEC on each host.  See the matrix previously posted above for the .vib to install once you're host has been updated.

  Note: after this upgrade, that you will be able to update regardless of your software of vSphere host or 1000v (without having to be updated to the other).  1000v VEM dependencies have been removed since vSphere 4.0 Update 2.

  Kind regards

• Cisco Nexus 1000V (separate host?)

  We look at this one I have not yet have my head wrapped around it, but, I think I understand:

  (1) you can have 1 or 2 VSM (primary and secondary)

  (2) Vincent becomes an integral part of the kernel for ESX 4 host you want managed by these VSMs

  (3) a VSM will manage only a single ESX cluster.

  My hypothesis is that these virtual devices VSM would live within the cluster, it runs along side VMs however; This diagram (attached) seems to show the VSM on an ESX host, which is not an instance of separate VEM?

  It seems that the benefit to this 1000V is less if you need to buy 1 (2 for HA) or the ESX hosts through a license to support these virtual appliances.

  I understand that correctly?

  Yes, we do like control and packages must be on their own NIC in reality you can stick them anywhere. The amount of traffic that send us via these networks is low (except package when you ERSPAN). On our side there is concern that, if the network is busy the VSM could lose a few heartbeats of the MEC and remove it. Looking at your environment I'd stick control and the package on the natachasery used for the Service Console. That way all your control traffic is isolated from VMK and data.

• The Cisco Nexus 1000V VSM port group settings?

  I could not find the Group of port settings when executing the VSM in a virtual machine covered in the Cisco documentation... they say just 'create 3 groups of port '.   But, the configuration of VLANS to these pages are not clear to me.

  In the configuration of VSM, you set the VLAN on each network (Mgmnt, control, package).   This means that the VM VSM will be production of marked packets, so groups of port must be set as master / virtual tag comments.

  But, if this is the case, why they recommend 3 groups of ports?  You should be able to use a trunk port group and letting the physical switch the VLAN.  Thus, they rather waiting for assignment of VLAN will be on the Port groups?

  The Cisco config docs give much information on the Cisco command line configuration...  Some may give, or point, the settings on the VMware port groups when using MSM in a virtual machine?

  Hello

  VSM virtual machine generates no marked packets but depends on the configuration of the port group VLAN ID Vswitch to label.  It's done as having evacuated the computer host computer on the vmnic associated the Vswitch.

• VM - FEX and Nexus 1000v relationship

  Hello

  I'm new in the world of virtulaization and I need to know what the relationship between Cisco Nexus 1000v and Cisco VM - FEX? and when to use VM - FEX and when to use Nexus 1000v.

  Concerning

  Ahmed,

  Nexus 1000v is a Distributed Switch that allows you to manage your VEM, see this relationship as a supervisor-LineCard relationship.

  VM - FEX gives you the opportunity to bypass the vSwitch embarked on each host ESXi (VEM) for example.

  With VM - FEX, you see the virtual machines as if they were directly connected to the Parent switch (N7K / 5K for example), making it the parent spend management (cause there is more no vSwitch in the middle).

  This is a good topic that can be discussed and is difficult to summarize in a few lines, you read something in particular? any questions or doubts we can help clarify?

• Design/implementation of Nexus 1000V

  Hi team,

  I have a premium partner who is an ATP on Data Center Unified Computing. He has posted this question, I hope you can help me to provide the resolution.

  I have questions about nexus 1KV design/implementation:

  -How to migrate virtual switches often to vswitch0 (in each ESX server has 3 vswitches and the VMS installation wizard will only migrate vswicht0)? for example, to other vswitchs with other vlan... Please tell me how...
  -With MUV (vmware update manager) can install modules of MEC in ESX servers? or install VEM manually on each ESX Server?
  -Assuming VUM install all modules of MEC, MEC (vib package) version is automatically compatible with the version of vmware are?
  -is the need to create port of PACKET-CONTROL groups in all THE esx servers before migrating to Nexus 1000? or only the VEM installation is enough?
  -According to the manual Cisco VSM can participate in VMOTION, but, how?... What is the recommendation? When the primary virtual machines are moving, the secondary VSM take control? This is the case with connectivity to all virtual machines?
  -When there are two clusters in a vmware vcenter, how to install/configure VSM?
  -For the concepts of high availability, which is the best choice of design of nexus? in view of the characteristics of vmware (FT, DRS, VMOTION, Cluster)
  -How to migrate port group existing Kernel to nexus iSCSI?... What are the steps? cisco manual "Migration from VMware to Cisco Nexus 1000V vSwitch" show how to generate the port profile, but
  How to create iSCSI target? (ip address, the username/password)... where it is defined?
  -Assuming that VEM licenses is not enough for all the ESX servers, ¿will happen to connectivity of your virtual machines on hosts without licenses VEM? can work with vmware vswitches?

  I have to install nexus 1000V in vmware with VDI plataform, with multiple ESX servers, with 3 vswitch on each ESX Server, with several machinne virtual running, two groups defined with active vmotion and DRS and the iSCSI storage Center

  I have several manuals Cisco on nexus, but I see special attention in our facilities, migration options is not a broad question, you you have 'success stories' or customers experiences of implementation with migration with nexus?

  Thank you in advance.

  I have questions about nexus 1KV design/implementation:
  -How migrate virtual switchs distint to vswitch0 (in each ESX server has 3 vswitches and the installation wizard of VMS only migrate vswicht0)?? for example others vswitchs with others vlan.. please tell me how...
  [Robert] After your initial installation you can easily migrate all VMs within the same vSwitch Port Group at the same time using the Network Migration Wizard.  Simply go to Home - Inventory - Networking, right click on the 1000v DVS and select "Migrate Virtual Machine Networking..."   Follow the wizard to select your Source (vSwitch Port Groups) & Destination DVS Port Profiles
  -With VUM (vmware update manager) is possible install VEM modules in ESX Servers ??? or must install VEM manually in each ESX Server?
  [Robert] As per the Getting Started & Installation guides, you can use either VUM or manual installation method for VEM software install.
  http://www.cisco.com/en/US/docs/switches/datacenter/nexus1000/sw/4_0_4_s_v_1_3/getting_started/configuration/guide/n1000v_gsg.html
  -Supposing of VUM install all VEM modules, the VEM version (vib package) is automatically compatible with build existen vmware version?
  [Robert] Yes.  Assuming VMware has added all the latest VEM software to their online repository, VUM will be able to pull down & install the correct one automatically.
  
  
  -is need to create PACKET-MANAGEMENT-CONTROL port groups in ALL esx servers before to migrate to Nexus 1000? or only VEM installation is enough???
  [Robert] If you're planning on keeping the 1000v VSM on vSwitches (rather than migrating itself to the 1000v) then you'll need the Control/Mgmt/Packet port groups on each host you ever plan on running/hosting the VSM on.  If you create the VSM port group on the 1000v DVS, then they will automatically exist on all hosts that are part of the DVS.
  -According to the Cisco manuals VSM can participate in VMOTION, but, how? .. what is the recommendation?..when the primary VMS is moving, the secondary VSM take control?? that occurs with connectivity in all virtual machines?
  [Robert] Since a VMotion does not really impact connectivity for a significant amount of time, the VSM can be easily VMotioned around even if its a single Standalone deployment.  Just like you can vMotion vCenter (which manages the actual task) you can also Vmotion a standalone or redundant VSM without problems.  No special considerations here other than usual VMotion pre-reqs.
  -When there two clusters in one vmware vcenter, how must install/configure VSM?
  [Robert] No different.  The only consideration that changes "how" you install a VSM is a vCenter with multiple DanaCenters. VEM hosts can only connect to a VSM that reside within the same DC.  Different clusters are not a problem.
  -For High Availability concepts, wich is the best choices of design of nexus? considering vmware features (FT,DRS, VMOTION, Cluster)
  [Robert] There are multiple "Best Practice" designs which discuss this in great detail.  I've attached a draft doc one on this thread. A public one will be available in the coming month. Some points to consider is that you do not need FT.  FT is still maturing, and since you can deploy redundany VSMs at no additional cost, there's no need for it.  For DRS you'll want to create a DRS Rule to avoid ever hosting the Primar & Secondary VSM on the same host.
  -How to migrate existent Kernel iSCSI port group to nexus? .. what are the steps? in cisco manual"Migration from VMware vSwitch to Cisco Nexus 1000V" show how to generate the port-profile, but
  
      how to create the iSCSI target? (ip address, user/password) ..where is it defined?
  [Robert] You can migrate any VMKernel port from vCenter by selecting a host, go to the Networking Configuration - DVS and select Manage Virtual Adapters - Migrate Existing Virtual Adapter. Then follow the wizard.  Before you do so, create the corresponding vEth Port Profile on your 1000v, assign appropriate VLAN etc.  All VMKernel IPs are set within vCenter, 1000v is Layer 2 only, we don't assign Layer 3 addresses to virtual ports (other than Mgmt).  All the rest of the iSCSI configuration is done via vCenter - Storage Adapters as usual (for Targets, CHAP Authentication etc)
  -Supposing of the licences of VEM is not enough for all ESX servers,, ¿will happen to the connectivity of your virtual machines in hosts without VEM licences? ¿can operate with vmware vswitches?
  [Robert] When a VEM comes online with the DVS, if there are not enough available licensses to license EVERY socket, the VEM will show as unlicensed.  Without a license, the virtual ports will not come up.  You should closely watch your licenses using the "show license usage" and "show license usage " for detailed allocation information.  At any time a VEM can still utilize a vSwitch - with or without 1000v licenses, assuming you still have adapters attached to the vSwitches as uplinks.
  I must install nexus 1000V in vmware plataform with VDI, with severals Servers ESX, with 3 vswitch on each ESX Server, with severals virtual machinne running, two clusters defined with vmotion and DRS active and central storage with iSCSI
  I have severals cisco manuals about nexus, but i see special focus in installations topics, the options for migrations is not extensive item, ¿do you have "success stories" or customers experiences of implementation with migrations with nexus?
  [Robert] Have a good look around the Nexus 1000v community Forum.   Lots of stories and information you may find helpful.
  Good luck!
