DVS LAG vs not lag

Hello

I have DVS 5.5 in my production environment with 2 cards active network on each host.

It is a HP Blade box and connects to the Nexus 5 K switches upstream.

According to the administrator of the network, the ports are configured for the vPC (virtual port channel)

I need to know the differences between creating a LAG and just using the network cards in an active/active configuration

What you can get using Nexus 5Ks and VPC is a effective is the distribution of West traffic. Virtual PortChannels on Cisco switches ensures that the traffic of all two virtual machines running on different hosts will always communicate via a switch upstream. There is an excellent article by Chris Wahl on this topic: revenge of the LAG: networks in Paradise

It is however more than a theory to practice. I've personally never seen proof of this contribute to any client environments.

  • Binding problem rising switch distributed - vim.dvs.DistributedVirtualPort is not available

    Hi all

    I am trying to add a physical link to a distributed switch rising.

    The story unfolded as shown below:

    -default ESX 4 generation created with virtual switch 'standard' with Teddy 0 uplink port & console running through this switch

    -new distributed switch created with groups of separate ports for console, VMkernel and VM traffic

    -Teddy switch 1 assigned as an uplink for distributed

    -new console and VMkernel ports created successfully on the distributed switch

    -console legacy & VMkernel ports correctly migrate from 'standard' virtual switch with for the distributed switch

    -removed 'redundant' console & VMkernel ports to the distributed switch, so there is only one of each kind on the left

    -' standard' virtual switch was successfully deleted

    -When you try to add Teddy 0 (which is displayed as unclaimed) as the second uplink to the distributed switch following error occurs:

    The resource vim.dvs.DistributedVirtualPort is not available in vim. DistributedVirtualSwitch dvSwitch

    Tips / advice / suggestions?

    Kind regards

    Radek

    You can update the number of dvUplinks in the properties of the dvSwitch in stock-> Networking.  Select the switch (icon with the + / according to him, not the object of the child).  It'll be here in the General settings.  You can also change the names of of the uplinks from here.

  • Does not not the path network in a reservation

    Hello

    I'm trying to set up the new booking. In a new tab of book storage, all storage LUNS are appearing, but in the network tab, it is to show that the group port DvS on which I configured my device and IaaS Server vRA. It doesn't show any other group port. I configured 4 groups of ports in my DvS with names, vLAN100, vLAN101, vLAN102 and vLAN103. I use for my device and IaaS vLAN100 and it is the only group of ports in the network path are not the other 3. Please advise and guide how to solve this problem.

    Thanks in advance.

    Solved the problem. Port DvS groups were not properly mapped to the hosts in the cluster. A mapped and ran the data collection, all him vLAN appeared successfully in the reservation network tab.

  • Definition of VLAN ID on vmkernel ports on dVS - Nexus 1000

    I noticed when adding vmkernel ports to a host on the dVS I'm not presented with an option to enter a VLAN ID. Is it because the VLANS is defined at the level of the port on the Nexus Group? Is there a need for me to create these ports on a vSwitch first to set the VLAN and then migrate them to the dVS?

    Thank you

    JD

    The VLAN ID is controlled by the port-profile on the VSMs 1000v. You don't have to specify it.

  • Can integrate us Oracle form recognition with AD

    Hi guys,.

    I want to implement the safety of OFR. We will use the OFR's web-based client. Now you can give the answer of the sub questions:

    1. There are two options to connect the OFR user, one is authentication of database and another is basic authentication Windows. Can I connect AD for authentication?

    2. If I can connect to base AD authentication then the way in which the role will come to user? What is the advertising group will be same as role in OFR? Same as content!

    3 OFR straightens capture export directory and create lot of OFR file, but I want to implement the auditor from different lots. Means different lots will have different Org_ID and this org_id user should see these lots to the auditor. How can I implement this type of scenarios?

    Thanks in advance.

    Kind regards

    Shad

    Shad,

    States that can be seen are in the section of the settings menu of the auditor under workflow, but it is not intuitive, right-click on the State of the left hand, normally 550 then you can add edit or delete States together 550, 551 and the user will see only the State 551 lots

    You save the settings of the Auditor in a .dvs file, if the user double-clicks on this he launched check with the settings chosen, or you can also call executable auditor with a parameter pointing to the dfs file. DVS to create 550.dvs files, 551. DVS etc. Not yet had to do using Web check but the parameters must take place somewhere in the designer you define the workflow for dealing with all States to 700 course

  • vShield Manager, virtual son VXLAN, uplink changes of VDS

    Need input on how to resolve this situation without rebuilding the entire cluster care...

    I have vSM for vCloud Director of VXLAN son/virtual networks. As a part of a host updates - migration of all 1 Gbit/s to 1 / 10 Gbps mixed - I was able to reorganize the network adapters on the host computers and add additional total ascending available on the DVS pass that VXLAN is "horse on.» As part of making these updates, I've renamed also uplinks, where mistakes and the discovery of the problem root.

    The errors were to appear when you try to instantiate a new network VXLAN. The vCloud error was pretty impenetrable (as usual), but trying to manually create a new network in vSM provides useful information: the error was a failure to set the mode of collection for the new port group, and it referred to one of the ancient names of uplink.

    After that I added rising additional "dummy" to the DVS and renamed them so that the old names have been included, the virtual wires could be built very well. However, by examining the exchange of news, it was clear that vShield were built using the original, pre-reconfiguration uplink names, ignoring all new uplink: the new rising have been defined as "unused" in the group properties and the 'active' were fake uplinks that had no physical associated cards!

    I restarted vSM, re-entered the credentials of vCenter to try to get it to re - sync with the configuration of the network, but nothing helped.

    I need a way to force vSM list again this DVS who uses VXLAN so that it will end up with the correct uplinks. So far, my Google-fu has failed me, so I hope someone on the Forum might have a clue. Heck, as far as I know, it is a defect that I just discovered...

    Assuming you are using "failover command" set up for your VXLAN, you can try to use the REST API to change the name of uplink in POSSIBLE Manager (almost similar to what you see in KB 2093324).

    Note : I recommend backup or snapshot Manager first! Just in case...

    Headers required such as:

    Accept: application/xml

    Content-Type: application/xml

    Basic authentication

    1 /

    Use GET on the following points for the VDS loan ':
    http:// /api/2.0/vdn/switches

    (of course replace the with the name or the IP address of your vShield/POSSIBLE Manager)

    You will get something like this (this is just a part of it, if you have several vDS):

    DVS-18

    VmwareDistributedVirtualSwitch

    DSwitch

    16

    VmwareDistributedVirtualSwitch

    Datacenter-2

    Data Center

    Cloud

    1600

    FAILOVER_ORDER

    Uplink 2

    Uplink 1

    fake

    2 /

    Modify the parts of that you need. For example:

    ...

    NewLink1

    NewLink2

    ...
    Leave the rest as what.

    3. /

    Then use to execute a 'PUT' to the URL below in the REST client containing the above (in step / 2) change of body (and once again: assuming you are using the failover command).
    http:// /api/2.0/vdn/switches/dvs-18

    Note: Replace "dvs-18" by the id between and to what you in the GET request (in bold and red).

    You should get a HTTP 200 code if everything is OK. See: vShield API Guide around page 154, but personally I think that the part "Edit Group Policy" is not correct.

    It won't change any existing in vCenter port group. You have to change them manually. This change is only for any other creation of sons v VXLAN.

  • Why Firefox does not lag when scrolling through some websites?

    I tested my current profile with all my addons activated and compared it to a whole new addon-free profile. Own profile showed no difference in my current profile; the shift happens on the profile to both clean and current. Disabling scrolling without jolts and hardware acceleration allows nothing. This same site, chrome and Opera both show zero lag, the functions of the site perfectly.
    I use Linux as an operating system, but during startup in Windows FF, the lag is there too. IE scroll normally on this site too.

    Here is a page where the offset of scrolling happens. LAG happens during the major part of sites Yahoo, if I'm not mistaken.

  • Notes app so much lag after updating iOS 9.3

    Is anyone else having problems with an extreme shift in the Notes application after update 9.3?

    I mean, extreme, it may take 15 seconds or more to meet the press of button, or the tapping of an icon, in the Notes application. This happens only in the Notes application. All other aspects of the device are absolutely perfect.

    It does not appear to be linked to the note of size. This can happen with a new note.

    I believe that this can be related to synchronization. I've got 9.3 on my iPhone 6 Plus and iPad Pro. If I turn off one of the devices completely, there seems to be zero lag when I edit a note on the other device. However, as soon as I got the two devices, the LAG is.

    Similarly, if I turn off the synchronization of Notes under parameters iCloud on one device, it starts immediately respond normally on the other device. Turn on the option, and back comes the lag.

    I like to use the Notes app to make quick notes when out and about, but this problem has made almost unusable for this purpose.

    Any ideas/suggestions?

    Kind regards

    Mark

    Well, I guess it's me then with Notes of Apple.

    Not only is the above past again, but synchronization has now ceased between my devices, making them practically useless soft.

    I tried to reset all settings, signature of iCloud on all devices and back to hard re-boots etc and nothing works.

    Such a shame, because they finally got the application up to the point where it is excellent functionally, but ruining with all these problems.

    I'm starting to think of Apple should just stick to the material and traditional software, because they just do not work the cloud at all, even after all these years.

  • Lead - Lag.vi - I do not understand the calculation

    Hello

    I try to use the lead block - Lag.vi of the Toolkit, but I don't understand how it works. When you open the Panel sound, it looks like this:

    The indicated calculation is not what I expected, im sure that this is not how to drive of the LAGS should work. Should not be two poles and zeros? I guess that the expression of attenuation is included in the gain?

    If anyone knows and can let me know, would be great.

    Thank you

    Adam

    The VI is either directed OR Lag according to the pole / location zero. You should consider the time progresses and the delay in terms of bandwidth.

    Tlead = a * T

    Tlag = T

    If P = 1/t.

    Z = 1 / aT

  • M4800 Precision: Input lag with a log in, Switchable graphics does not, fan GPU "chirp" when it starts.

    I recently bought a new M4800 for an i7 quad, and a m5100 over-pants GPU. So far, I was rather satisfied with the purchase as it is what I need it to do. However, there are a few quirks that prevent from being 100%:

    When I run the map only descrete, the journal of windows 7 in a such shift except if I move the screen does not refresh: you can type things and no. * display symbols in the password box. If you move the mouse continuously when you type the * poster in real time? It's a weird kind of lag, that I have never experianced before in my life.

    This does not happen with the integrated card. HOWEVER, the computer will not dynamically switch between Intel processors and AMD gpu (amd Enduro / express power) as advirtized. When running in switchable graphics mode drop-down lists of global settings are 100% Virgin in the Panel of the CCC.

    If you manually set for each application: it performs either one of two things:

    (1) most games seem to run fine, however he follow up with ESTR indicates its operation on the intel HD GPU and performance decreases significantly in the reflection of this...

    or (2) launches a professional software as Chief Archetect x 6, or SolidWorks2014 causes the display to hang, fans of cut and the computer did nothing until a hard reboot via the power button.

    * I disabled the Integrated GPU in the bios and run only the AMD card as a work-around. Is there any solution for this other than to ignore the Intel card? Googling around leads me to a resource that graphic dell switchable disbling in BIOS are the only work around. All the programs work very well in this way, but sometimes say on a trip or during a course of reading, I don't see a reason to keep the amd WHAT GPU powered.

    Soruce to work around www.dell.com/.../EN

    Is this fixed in a future bios or update driver?

    and finally: the computer is dead silent most of the time, even the fans are pretty quiet. However when the GPU kicks fan on after being off for a long time, there is sometimes a noise, I can only describe as "electronic chirping/scraping" until the fan whirrs to life, it affects not at startup, but randomly as you use on battery and plugged. the configuration management thermal "maximum performance" to keep the fan on all the time to a certain extent eliminates noise. Is this normal? or is this a problem?

    My personal experience has been a long and trying a.  First, they sent a technician to replace the graphics card with an another week.  Has not made a difference.  While they had tech replace the motherboard.  No difference.  So, I insisted on a new m4800 with the nVidia processor.  That's how I got mine.  BUT I think that if you pushed, maybe they could send a technician to change your graphics card.  Or at least send you a different model (for which you need of course a different driver), then you could install or take to a repair technician.

    For what it's worth, Dell knows they have a problem with this hardware configuration and told me that they raised the question to their experienced engineers.

  • Dragging my updated firefox to update to the latest version and now the game I play which is a flash based game lag all the time in firefox, but not in Internet Explorer

    OK so I play a game called Emporea on my PC and it uses flash, I've never had a problem then I refreshed firefox as she suggested and it updated to the latest version, I've never had problems with it before on previous versions and now, with this, the lag is so bad that it makes the game almost unplayable. I tried to open it in other browsers such as IE, and it works very well in people. so, the question is somewhere with firefox, I've updated my flash drive and still no change in firefox

    One of the changes in Firefox 48-49 title is e10s, separating the process of browser interface process page content. The performance impact of this can vary a lot between the systems, and it would be useful to know if you have this feature enabled. To check this, either:

    • button '3-bar' menu > '? ' button > Troubleshooting Information
    • (menu bar) Help > troubleshooting information
    • type or paste Subject: support in the address bar and press enter

    In the first table on the page, find the line of Multiprocess Windows and see if the number on the left side of the fraction is greater than zero. If so, you are using e10s.

    If you use e10s:

    To determine if this feature is causing this problem, you can turn off as follows:

    (1) in a new tab, type or paste Subject: config in the address bar and press enter/return. Click on the button promising to be careful.

    (2) in the search above the list box, type or paste the cars and make a pause so that the list is filtered

    (3) double-click the preference browser.tabs.remote.autostart.2 to switch the value from true to false

    Note: the exact name of this preference may vary, but it will start by Browser.Tabs.Remote.AutoStart

    On your next startup of Firefox, it must be run in the traditional way. Any difference?
