ESXi 5 provides a great compatibility for several NIC?

Hi all

This is my first time to vSphere install, and I want to configure a vSphere cluster with a vCenter server, ESXi 12 and a central storage 5.

I intend to use 6 NIC for each ESXi, its use is less than

eth0 for vCenter/ESXi management

eth1 for vMotion

eth2 and eth3 to VM networks

ETH4 & eth5 for iSCSI (multi-path)

What worries me is the compatibility of multiple ESXi 5 NIC. all 6 of my ESXi NIC are Intel (2 exist on the motherboard, 4 from the Intel PCI-E network card)

Intel® 82575EB Dual - Port Gigabit Ethernet Controller (motherboard)
PRO/1000ET four-port network adapter for the server (network card)

Here are my questions:

  1. ESXi will still perform well? There is no bad effect of multiple ESXi of NIC? (It is generally understood that this NETWORK 4 ports card will consume a lot of CPU and memory)
  2. Can I have 'real' advantage of multiple NIC? There are many examples of books about vSphere implement, that we would make better use of each NETWORK card based on different functions, so several NIC is a good recommendation. Is it really a best practice in the actual implementation of vSphere? or even a golden rule to follow?

Any response will be highly appreciated and useful to me.

Because of the lag time (I'm in China), please execue if I so can't quickly at the time.

Your design concept of NIC has merit. The following link is a design article about 6 implementations NIC for vSphere 5 using IP storage:

http://vrif.blogspot.com/2011/10/VMware-vSphere-5-host-network-design-6.html

For a procedure step by step on iSCSI SAN Setup and configuration are trying the following (remember that this article is for vSphere 4.x):

  • Since the update Firefox 6.0, some websites do not load correctly. I suspect it has to do with the Java being disabled because of the compatability modules. When I try to go to Tools/Add-ons, I get the message "Loading" for several minutes without chang

    Update Firefox 6.0 is useless to me because many websites I visit are not displayed properly, I guess because the Java modules are disabled because of incompatibility. They appear correctly in Internet Explorer.

    In addition, the add-on from Trend Micro is not compatible, which leaves me with a positive feeling.

    When I try to check to see if these modules can be updated, the menu item Tools/Addons just goes to a page with "loading" and stays there for several minutes without change until I close it.

    I would like to know the procedure to regularize this version of Firefox to my previous version that worked.

    Firefox 5.0/5.0.1/4.0/4.0.1 and earlier 3.6.20 all contain questions of security and stability that will not be corrected. You put your system at risk by using any version of Firefox that 6.0 or 3.6.20. Any person who displays a link to other versions is to be irresponsible, in my opinion.

    Java

    If the incompatible extensions in Add-ons > Extensions are Java Console, you have no need them unless your doing Java development. Most of the users have not yet installed, but Java will install Java Console with each update. You can delete them manually:

    The only thing that affects the functioning of the sites/Java applets on the web is the plugin (Add-ons - > Plugins) "Java (TM) Platform SE (version)". Do not forget that it is enabled and that you have not all extensions which affect/block "scripts".

    Trend Micro

    You must contact Trend Micro or go to the forums on their website to inquire about their plans to update the add-ons/toolbars they install in Firefox.

    Problem with the display of the Add-ons Manager

    The Add-ons Manager gets in a loop of loading due to the recent update of Firefox 6 and servers being overloaded because users and update process are looking for updates to the add-on. If you stay away from the "Get Add-ons" selection on the left of the screen of the add-on Manager, you should have no problem with that. This situation is expected to resolve when the overload of Firefox 6 update is complete. I do not always use this "Get Add-ons" option, instead, I go to the website of modules and the search for what I want from there: https://addons.mozilla.org/en-US/firefox/search/?q=clone & cat = all & x = 0 & y = 0

    Original title: I get code 31 for several drivers

    I get code 31 on several drivers, including V9 drivers and when I troubleshoot it shows each issue with the driver separately and gives the possibility to fix it by reinstalling. It does not work.  When you try to update I get the message that I have updates. I've also not receive my updates until I ran C Cleaner, that allow to download updates, but this does not solve the drivers with the code 31.

    My only intention is to create a model/site based URM where we can provide functionality to scan for users. We want a distributed feature where users can scan the images remotely and commit to the WCC:Records / URM.

    Is it possible to be done through Oracle distributed Document capture (ODDC) and if it is possible how to connect ODDC with the client browser. Please suggest

    Ok. So, the answer is certainly: Yes, it is possible.

    The part of analysis, this is exactly what ODDC is good for. Unless you have the license already, however, you may have to go with the product to Capture Oracle WebCenter (large companies), which provides the necessary also.

    Regarding the validation and storage, ODDC/ODC/WebCenter Capture can commit images scanned at several depots, including University Complutense of MADRID (URM can be considered a Complutense University of MADRID with a specific purpose / several modules or components under voltage and configured). So, technically, he has no problem.

    When I have little doubt, however, is the meaning of the scenario - declaring an item as a record is an important event in the life cycle of the document - a record is often (or always) cannot be changed to ensure the integrity and non-repudiation of information. In this perspective, a direct validation of a recording of a scanning system (where errors such as bad scans, lack of pages, etc can be expected, particularly if the scanning is performed by the end user in a distributed fashion - so, not very experienced) seems a little dangerous.

  • Would it be possible to have 2 shared resources, a local containing all common topics and photos for several projects and another a remote control containing all the topics and pictures for the purpose of collaboration

    Hello

    I was wondering, now that I discovered the benefits of eating of the resource, if it would be possible to have 2 shared resources, a local with common themes and images for several projects and another one, remote, containing projects together, i.e. the subjects and images, for collaboration purposes.

    The only local, I intend to use it for my purposes to have common points (topics & photos) update of all projects where they appear and the distance that I intend to use it with remote colleagues, who might want to make changes in the topics.

    This would mean that the topics and current photos will be present in the resources, one local as one remote.

    Thank you.

    SVN is not a source control package?

    I'm not sure, but RoboHelp * MAY * be able to integrate with SVN to control projects and sharing.

    RoboHelp comes with RoboSource Control that could be used to provide the source code control. But if you already have a package in place, my thought is why reinvent the wheel? Simply use what is there.

    As a first step, I think it is caused by the automatic locking of cuz I'm really annoyed by this last, I uninstalled it.

    However it still does not.

    Could someone tell me what the problem is on the Earth?

    It's maybe just because I really don't know with my new laptop.

    It's a power setting that determines how long before its entry in the screen saver, sleep more, or even in hibernation mode. You can change the requirement for a password (somewhere in the Windows screen saver section) or the duration before entering these modes (you should be able to define with the Lenovo Power Center thing). Of course, making one is a security risk, but it is up to you as to how much safety or comfort desired.
