Choose a type of network pool for my cloud of assessment

I have implemented a vCloud Director about after the installation of the device in the "assessment" vCloud guide.  This guide assumes that supported VXLAN network pools will be used; Apparently, I didn't switch support for this scenario.  Rather than kind, I want to just my cloud assessment to the top and do work.  With this in mind, I'm trying to understand that an isolated Cloud network will work for me.

I have:

(1) a distributed switch

(2) VLAN and ip address ranges available to me

Looks like it's all I need to succeed; I guess that the vlan is optional, but I will need to specify one of my VLAN, if I understand correctly.  I'm kinda new to these topics of networking, but if ago ever VLAN on the physical layer, I have to specify a network pool, correct?

My main question is about the MTU.  The increase of the MTU is only performance?  I understand that the tunneling information makes the total image bigger than the standard 1500 bytes and that cause the fragmentation, but if this unique performance, then my assessment needs do not require that I do the MTU setting, at least as far as I can see.

Thoughts?

About fix 1 VLAN 1 ration of network Pool.  Think of it as a way to privatize the multicast traffic that is vCNI (vCloud network isolation)... which is a type of network pool.  For vCNI, I think you get 1000 networks isolated by the pool (which has 1 VLAN).

No IPs really needs don't really exist on this point, since it's all multicast traffic (AFAIK).

MTU is mainly on performance.  If you want to use vCloud network... isolation you can do in the MTU 1500... you create the pool on one VLAN specific (that exist on your network fabric) and once the pool is created... drop the MTU in the properties of the pool of 1476

    What can I do?

    Hi repudiation.

    The email you use here on the forums is associated with Australia for the country which is probably the cause. You will probably need to change your Adobe ID email address current (even if its correct) to something else in order to release of the it.

  • During the new installation of xp pro, the program never asked for the product key or what type of network installation.

    I think that when you install XP and turn on the first time, Microsoft collects information from your system during this process to develop a signature of material that goes with your license and store it away.  Of course, they do not collect any personal information :)

    They do it so that if someone takes your XP installation license and tries to apply it to another computer (it is piracy) that the installation would not activate as your activation must match your hardware.

    If someone tried to install and activate your license on another machine with a different set of hardware, MS would say, wait a minute - this license has already been activated on another machine, and he could complain.  Then someone has some ' splaing to do.

    I suspect that in your facilities in 2nd and 3rd, MS takes a look at things and said... this material signature and the license already go hand in hand, that nothing has changed here, so it is not necessary to activate again, all right.

    This is why, if one day you need to replace your motherboard and reinstall XP, even if you have everything and it's all legitimate, you will probably have to reactivate again since the signing of material would be completely different for this license that MS remembers the first activation.  A few small hardware changes, that you can get away with, but if the number of points collected to compensate for the signing during the initial activation is too different, you will need help activating.

    In this case, if things are legitimate, you can call MS activation team, and if you can convince them that there is no hacking involved and you just have to change your motherboard, they work with you to get your reactive stuff.

    Since you are looking at AUMHA, they have a writing little upward about it here, but there are official documents of Microsoft you can read also ('points' and how they work):

  • EFI network 0 for ipv4 boot fail

    Hello guys. don't know if this is the right forum but if not, redirect me somehwere else.

    but I have this problem and hope one of you can solve it. I have lenovo p500.
    He had run without giving me a single problem until today. It worked very well until 30 minutes ago, the entire frozen screen just about me - no problem.

    Sometimes and all I had to do was simply to restart and I'll be back on the right track, but nope - black screen appears with a message "checking media".
    then it would fail then a blue screen would say
    "Lack of device by default initialization or initialization failed
    Insert the recovery media and press a key
    Then select Boot Manager to choose a new device Boot or Boot Recovery Media"
    then he would take me to Boot Manager where he would give me only two options
    "EFI network 0 for IPv4 (B8-88E3-8F-4 d-B3).
    "EFI network 0 for IPv6 (B8-88E3-8F-4 d-B3).

    Hi mafew,.

    Welcome to the Forums.

    The hard drive seems to be bypassed, and the device starts directly to the network. You can try to:

    1. boot in the BIOS (press Fn + F2 on startup) and check if the hard drive getting detected on the information tab.

    Link to photo

    2. If the HARD drive is detected, go to the Startup tab and make sure that it is the first start. If it still does not work, try to disable UEFI and press F10 to save and exit.

    Link to photo

    If the HARD drive is not detected, you may need to contact lenovo for the service because there is probably a fault on the HARD drive.

  • Select a type of user account (for example, standard user, restricted user, and other types) on computer XP pro?

    Hello.

    I have a question about how to select the type of user account for each user account.

    I read that if I type 'control userpasswords2' term, it will bring up a window of hidden user accounts.  In this window, select a name of the user account and click property, click on membership group and it will show all the type of account you can purchase (including the standard user, restricted user, the other who has many other types)

    Here is the link I read

    Let's say my computer is XP pro and it is in the home (not domain joined ) working group. Am I able to set these types of accounts to my user account using 'control userpasswords2' just as I explained above?

    I was wondering because I read in the microsoft help article or somewhere that it indicates that the computer must be on the field to be able to choose the type of account by using this process, I explained, and one account type you can choose where your computer is located in the Working Group's account admin or limited using the control panel then click on accounts of users... but other said it should not be on the field... I got confused.

    I would like to try it myself, but I don't have XP pro computer with me right now, I'd appreciate it really if someone could help me with the answer.

    Hi greenyy,

    If you are the administrator of the machine Windows XP Professional, you can use the command 'control userpasswords2' and access the list of user accounts and change the type of account.

    You need not necessarily be on a domain, however, it may not work for some types of user accounts on a working group.

    A test, you can try to change the type of account for user accounts & check if it works.

  • Question about the collection of NETWORK adapters for vMotion / VM vSwitch

    Hello

    We use vSphere Enterprise Edition 5.1.

    We also create separate vSwitch for management / vMotion and VM.

    Each vSwitch receives 2 network cards connected to the different switch for redundancy.

    We would like to know is necessary to provide the collection of NETWORK adapters for these vSwitches?  Currently, only enable us NIC Teaming for VM vSwitch only.

    Thank you

    VSwitch vMotion, we have 2 assigned NIC (nic2 and nic6) with 10 VLANS.  NIC2 and nic6 are connected to 2 different physical switches.

    Should I choose

    (1) both are active

    (2) both are assets + grouping of NETWORK cards?

    Question - if there is only 1 VLAN, it seems that NIC Teaming is also not very useful unless we use 2 VLAN (Multi-NIC vMotion).  Is this right?

    If you use Multi-NIC vMotion, there is no need to have two different VLANS, all you need is depending on configuration

    on your vMotion switch, please create two vmkernel port for vMotion with the same VLAN ID, but the grouping of NETWORK cards as below

    vMotion_1 - VLAN ID: 10

    Grouping of NETWORK cards

    vmnic2 - active

    vmnic6 - watch

    vMotion_2 - VLAN ID: 10

    vmnic6 - active

    vmnic2 - watch

    I have seen that there are being managed - network, property of the VirtualMachine managed - object, but I don't know how to use it in my code and if contains the information I need (maybe "Summary")

    Example here is one:

    in this case, I would like to know for this virtual machine

    and if it is possible information 2) and 3) for each NIC... in this case for NIC LANBAKUP...

    I realized prior extraction DVS elements:

    My $dv_switches = Vim::find_entity_views (view_type-online 'DistributedVirtualSwitch', properties-online ['name', 'uuid']);

    Then, you can search by UUID:

    ($this_dvs) = grep {$_-> eq {'uuid'} $the_uuid} @$dv_switches;

    This will give you the best performance as well, since you don't have to hit the API for each request (just the first effective request DVS).  You can add additional DVSwitch object data if you need it in your logic.

  • Need ip vm info to change the type of network adapter

    PowerGui FAQ.

    Q: how to start the administration Console in 32-bit mode on a 64 bit system?

    When you first install PowerGUI, on the last page of the installation there is an option to open the administration Console.  This option will open the default version of the administration Console.  The default version is 64-bit on 64-bit computers, or the 32-bit version on 32-bit computers.  Actually, on computers 32 bit, there is only one version, 32-bit version.  The PowerPacks to use a feature that is only available in mode 32 bits, so you can open the administration Console in this mode to use these PowerPacks.  To do this, you have a few options:

    1. from the start menu, open the programs PowerGUI, then x 86 folders and click the shortcut of PowerGUI x 86 to open the Management Console in 32-bit mode.

    2. in PowerShell, run the following command: & ${env:ProgramFiles(x86)} \PowerGUI\AdminConsole_x86.exe }

    3. in cmd.exe, run the following command: "% programfiles(x86) \PowerGUI\AdminConsole_x86.exe"

    Note that you can have only one instance of the Console of administration open at a time, so if you have already opened the Management Console in 64-bit mode, you need to close this window before you open the Management Console in 32-bit mode.  Also note that you may need to wait a few seconds after closing the window of the Management Console for the process to stop completely, how you can re - open it in 32-bit mode.

  • Best practices for the collection of network adapter for network management

    Quote from http://www.vmware.com/files/pdf/techpaper/VMW-Server-WP-BestPractices.pdf :

    Aggregation and network management networks:

    To set up a team of network for the management network adapter, configure the network adapters in the vSwitch
    configuration of the ESX/ESXi host, for configuration active / standby.

    The vSwitch must be configured as follows:
    The load balancing • route = based on the original (default) virtual port code
    • Restore = 'No '.
    • vSwitch0: two physical network adapters (for example: vmnic0 & vmnic2)
    • Two groups of ports (for example, vMotion and management)

    In this example, the management network works on vSwitch0 as active vmnic0 and watches over vmnic2.
    The vMotion network works on vSwitch0 as active vmnic2 and watches over vmnic0.

    My configuration:

    The two active adapters (not active / standby)

    Failback = 'Yes '.

    Not clear if the network management and vMotion are both active on the same vmnic or different.

    Question:

    Is smart enough to keep the network management and vMotion on different vmnic SE to ESXi 4.1 or I should change to active / standby config and make sure they are on different vmnic?

    It would make a noticeable difference?

    Ah yes, you are right in your configuration then.  I would never mix NIC vendors in any type of trunk, I saw things get funky now and then.  VAAI won't give you an advantage when you do a storage vMotion, normal vMotion will always use the same amount of traffic, because memory cards must always be copied between hosts.  It is advisable to devote at least a card NETWORK management and at least one NETWORK adapter to vMotion, if you can have two vSwitches with two NIC each then I would use explicit order of failover you mentioned.  Hope that helps!
