separate subnets for the ESX/ESXi management ports (vMotion, manage, FT, etc..)

Is it better to have all of your VMKernel ports on the same subnet or subnets separate (one for each role, iSCSI, management, vMotion, FT)?  Are their potential problems with either scenario?  Please include the ESX and ESXi.  I want to get my setup just as it should. Please let me know also if you need additional information.

I have licenses for ESX and ESXi, but I'm leaning toward ESXi are all vSphere 4 Update 1.

Hello

In fact, you have to use separate subnets for your vmkernel ports but they can run on the same thread. You can share a subnet between a vmkernel and service console, but not between two vmkernels. Just like that. So yes, you need to use several subnets.

  • Error: "no physical memory is available to the location required for the windows boot manager." The system cannot continue. "

    I have a stable system that works with a processor E6300, card mother evga 680i, graphics card 8800gts and 8gbs of RAM running on ulitmate windows 7 (32 bits - I decided to re - install with 64-bit to use the extra 4 GB of RAM, after I deal with the question below).

    I recently tried to add an adapter of Intel RS2WC080 SAS/SATA controller in a PCI express slots on the card mother 680i. I know that the card works (such as "it works very well in another motherboard), but for some reason when I put it in the 680i mobo I get the following message appears when I try to start windows. (i.e. the raid controller has no windows on the disks. I always use original hard drive always connected on the same Sata port on the motherboard)

    "No physical memory is available to the location required for the windows boot manager." The system cannot continue. "

    I tried to turn off virtually everything I could in the bios of the motherboard as an experience (including the things I needed). I also disabled the Intel RS2WC080 card bios.

    I'm puzzled. So what I want to know is simply a hardware compatibility problem, or is there some kind of workaround I can run in windows 7. For example, is there maybe some sort of way for her to start using a different memory location than its currently using? (Or is it something error message related to the memory of the bios that can only be overcome with software?)

    Thanks for any help.

    I tried to disable everything in the bios... including the things I needed. No luck

    Thank you very much for the reply Chris but I don't have abandoned bascially. Right now I guess the card and the 680i have some kind of incompatibility and I will just get a different mobo.

  • Comments about "VMware KB: verification of the deprivation of resources of the ESX/ESXi Service Console ' (1003496)

    Hi and happy 2012!

    Is the title of the article VMware 1003496 KB (Knowledge Base) - http://kb.vmware.com/kb/1003496 - "VMware KB: verification of the deprivation of resources of the ESX/ESXi Service Console" (article updated May 16, 2011). A better title might be "VMware KB: searching for deprivation of resources of the Console of the ESX Service / ESXi Tech Support Mode" since ESXi does not have a "Service Console".
    Article also mentions in ESXi running the command "top":
    " (...) ESX/ESXi includes the top utility to be able to check the use of the resources on the service console. (...)"
    " (...)  To check the use of the methods on the service console:
    1. Sign in to your service console of the ESX host as root from a SSH session or directly from the console of the server.  If you connect ESXi Support mode.
    2. Type back to top ."

    However, if you enable the Remote Tech Support Mode (SSH) in ESXi (at least in ESXi 4.1 Update 1) - similar to a "Service Console" - the 'top' command seems to not be available:
    ~ # top
    -Ash: top: not found

    ~ # find /-iname high
    ~ #
    On the other hand, the article could have mentioned "esxtop" which is available in 'ESXi' (at least in ESXi 4.1 Update 1):
    ~ # find /-iname esxtop
    / sbin/esxtop
    I hope this information is useful. I propose that this article (1003496) is updated accordingly.
    Thank you!

    Ricardo, we have updated the article to take account of the ESX Classic only.

  • Start stuck on "Please wait for the Local Session Manager."

    I would say that this problem started a couple of days. Went to start my laptop (Toshiba) and he sat on the "Please wait" message forever.

    Had no problems to start in safe mode. Looked up various ways of addressing the problem.

    Was able to change the resume date and back a few weeks ago. Still no luck. Happened to read something on a printer Epson being perhaps the problem driver (it was installed a day before the date of restoration chosen). Uninstalled the drivers, computer still does not start.

    Tried restarting running. I do not have the CD it came with Vista, but it was an option when you hold F8 during startup (I think?) Couldn't find any problems.

    Ran check on memory. No problem either.

    Changed settings for a verbose startup and ran a Diagnostic startup - all good for this. Then tried selective startup load system services... This is when the error occurs. When starting, it hangs on "Please wait for the Local Session Manager" and does nothing more.

    I looked in the event viewer to see what came that time and a couple mistakes were:

    Event ID 6000: winlogon notification subscriber was unavailable to handle a notification event.

    Event ID 7026: the next (s) start or start failed to load system
    spldr
    Wanarpv6

    It would be very useful for me not having to run my computer in safe mode automatically all the time, although it is useful that I at least have that option. Any help is greatly appreciated.

    Hello

    1. by chance your computer is connected to a domain environment?

    2. as you mentioned in your article that you tried the selective startup, I want to confirm if you have disabled the services left 3rd after hide Microsoft services?

    If you did not disable these services make sure you disable and then check if it works.

  • Virutal Center can work next to the Vmware ESXi management package

    Hi all

    VMware currently has a promotion on Vmware ESXi management kit which is basically a Virutal Center Foundation license. That being said if you already have a virtual Center Server for all of your ESX servers could run a 2nd VMware ESXi management kit virtual Center Server for all your ESXi servers in parallel? or they will conflict with each other?

    My understanding is you can run as many virtual servers Center like you license but you can have than 1 ESX Server any attached to 1 Virutal host at any given time.

    We run 7 instances vCenter, so yes it is possible.  In addition, as you said a host ESX (i) can be managed by a single instance of vCenter.

  • Multi-port USB adapter for the MacBook USB - C Port?

    Hello

    I'm in pain, trying to find a USB adapter multi-port for my MacBook 2016, which only has a single port USB - C which is also like a power port.

    I already done is connect the WD My Passport drive external HARD to the MacBook via an adapter HooToo, that to see any HARD drive mounted in OS X.

    OS X makes a sound when it is connected, but apparently the adapter provides insufficient power for the HARD drive needs to be loaded.

    I got Belkin USB multi-port here:

    http://www.Apple.com/us/search/USB-ports?SEL=accessories & src = SERP

    But it is not certain if one of them provides enough power, so I would try rather than a person has used successfully with a MacBook and an external HARD drive,

    If not, opt for a multi-port adapter USB brand Apple.

    Please let me know about your experience or an Apple adapter.

    Thanks in advance

    My Apple 3 port works as advertised. The USB port has a perfect compatibility with the old and readers USB 3, my adapter Ethernet USB Apple and Trendnet USB adapter that I use in series. This includes the perfect function with a 10 VM Windows via VMware Fusion.

    A non - Apple C to an adapter that I bought works fine too. I don't see the brand on this subject but he chose via Amazon ratings. There were some with higher ratings, so that's how I made the choice.

  • X 64 Vista - Home Premium SP2 - game Second Life-need to create 2 folders to destination AppData or separate directories for the Viewer 1.23 and 2.2 caches

    I'm not a developer or a tech: only second life 1.23 is loaded on the computer – no productivity software. I need to create 2 folders to separate destination (or directories) to the SL Viewer 1.23 and Viewer 2.2 caches.  Right now the 1.23 cache is stored in the folder AppData/Local.  When 2.2 is downloaded, it will not replace 1.23, but things & Stuff Blog of Nalates Wordpress (also a contributor to regular Forum SL) recommend to around 2.2 to another 'file' or 'directory' cache (before the opening of 2.2 for the 1st time) to prevent the inventory and avatar problems loading again (when I had 2.1 load on the computer with 1.23) when I switch using the Viewer 1.23 and Viewer 2.2.  I don't know how to do this, but reading the wiki in Second Life in caches that directed me to the website of Microsoft, it seems that I need to get/use one command Linkd.exe which is part of the Windows Server 2003 Resource Kit Tools - but a note on the site of Microsoft for the Kit, under requirements of the States that the Kit is not supported supported on 64-bit platforms.  What to do please?  TY

    Hello

    a. go to the Preferences tab which displays your location of the cache.

    b. click on the 'Browse' (viewer 2.0) or the button "Set" (Viewer 1.23), create a new folder in a convenient (for example on your desktop) and select the folder to be your new location of the cache. Relog.

    c. This will give you a nice clean cache folder and do delete everything out of it easier in the future. If you use 3rd party clients, such as the Kirstens display, you might want to give them a separate folder, if they themselves (for example, Kirstens viewer uses "s20 C:\Users\yourusername\AppData\Local\Kirstens")
