• Question about Lab Manager and ESX Resource Pools

  Hello world

  I was wondering if I can get feedback from some of the members of the community.  We used Lab Manager very strongly in our support organizations and it has proved to be a valuable tool.  Recently, we collaborated with the Department of technical training and started hosting online seminars and classes for them using Lab Manager.  Last week we had a fairly large class of users (approx. 45), each duty deploy 2 rather Beefy VMs that were very intensive resources (Jboss, SQL, Mail to name a few).  My colleague and I went through a lot of trials and planning to ensure that our infrastructure can handle the load while allowing our users to date at the same speed and reliability, so that they are used.

  Our Lab Manager ESX server pools made up of the following:

  5 HP DL380 G5 servers with 2 x Quad Core 2.8 GHZ processors (8 cores each) with 32 GB of RAM each

  2 HP DL580 G5 servers with 4 x Quad Core 2.8 GHZ processors (16 cores each) with 128 GB of RAM each

  When the class is running and everyone has made their 2 machines, we noticed for some reason, he was all on ESX2 and 3 deployment (380 s).  Then came the ESX alarms, use of 90% of memory, then more than 100% bringing the disk page.  The CPU usage was at a all time high.

  I look at the 2 580 s and there are about 4 virtual machines deployed on them.

  So my question is...

  How does he know where to launch a Virtual Lab Manager machine?  There's no sense 2 servers have been brought to the red zone, and almost overloaded when the 2 most powerful servers in my farm are nearly dormant.  I noticed sometimes in the past, but not this bad.  Normally, we have about 45-50 computers deployed at some point and it seems to spread them out properly.

  This group of training has access to the same LUN and ESX server with Betclick as any other organization that we have.

  We have decided hosting several sessions of training may be greater than this one and would like to know that the virtual machines will be distributed properly.

  I would like to know your opinion on this

  First to answer your question, then make guess what happens.

  As indicated in response Ilya, LM distributed VMs differently with active DRS resource pools and pools of resources without active DRS.

  LM place VMs when the DRS is not used.

  When DRS is used, we use the DRS admission control to select the host to place virtual machines.

  DRS is turned off, LM uses its own placement routine:

  For each virtual machine, LM filter all managed servers that cannot run the virtual machine. A complete list of patterns are:

  • The managed server has not enough memory or quota for virtual machine to run the virtual machine.

  • The host is not connected to the data store that is the virtual machine.

  • The virtual machine has active state (suspended) and the CPU of the server managed by the waking state has been captured is not compatible with the managed server currently considered.

  • The virtual machine has been a guest on 64-bit and the managed server is not 64-bit capable.

  • The virtual machine has more processors than the managed server.

  • The managed server is not accessible or is set to "prohibit deployments." Not reachable may mean that the lm-agent or its not to ping queries is not answer (this is visible in the list of managed server page).

  Once we have the complete list of eligible servers, we place the virtual machines on the host including the smallest (MemoryReservation % + CPUReservation %). By default, we reserve not CPU on LM VMs, this internship will be largely due to the memory on the host computers if you have not changed the settings of reservation of CPU on your virtual machines.

  For closed deploy to the PF3, force us all virtual machines to go on the same host, so if any virtual machines have any special data store / CPU type specification, all virtual machines is forced to go on this host. If there are conflicting requirements between different virtual machines in the same configuration, deployment will fail. Closed VMs also have another condition to check that is rarely achieved in practice: number of closed networks available on the managed server. By default, this is 20 and you will need more than 20 different configurations closed running on a managed server before you who will strike.  (LM4 allows Cross fencing host, so this does not apply in LM4).

  To make a guess blind because of your distribution problem - if you use the saved state and fencing, it's probably the type of processor.  Processor type can be checked on the host properties page.

  If you not are not I would check that the images can deploy on the 580 s by disabling the 380s and trying to deploy them.

  If you use DRS (which you're not), it could be due to deployment of virtual machines too fast for the algorithm of control for the entrance of VC.  An easy solution for this is to extinguish the DRS on the cluster manager of laboratory.

  We tested load internal repeatedly, the product QA in different laboratories, we run (LM has been used in VMworld Labs for the past couple years and internal systems of training and demonstration for our Organization implemented SE), so no need to worry about this.  I assure you that the first 'real' performance problem you will encounter will be almost certainly due to an overload of your storage array (too many IOPS / s)... and for that you have to distribute content in data warehouses and use techniques of creating paths to balance the load.

  Kind regards

• Cannot find lab HOL-SDC-1314 - vCloud Suite Use Cases - application implementation service (PaaS) - use of vFabric

  Hello

  I see in some references of documents to this laboratory HOL-SDC-1314 - vCloud Suite Use Cases - updated application in service (PaaS) - use of vFabric

  However I find it.

  I also tried to change the link to: http://labs.hol.VMware.com/hol/console/lab/hol-SDC-1414-hol

  and 1514. Always without success.

  What, please, can you

  How can I find these old Labs?

  Best regards Daniel

  Hi Daniel,.

  We do not keep the old versions in the HOL given the constraints of storage cloud. The current catalog HOL approximately 30 TB of storage and we have recently taken out of service about 20 TB of old pods in order to manage the development and preparation of new laboratories for the exchange of partner and VMworld 2015. You may be able to find the old pod, or something similar in one of the other clouds internal. I suggest you look in the catalogs of sandbox to see if something might meet your needs if HOL-SDC-1421 does not provide what you need.

  All the manuals we have available can be downloaded in PDF format from the website of HOL Docs: docs.hol.vmware.com/catalog

  There is a product search option. Unfortunately, we have more manuals before 2014 available here.

• Why move them to the bottom of empty in VMware Lab Manager when you use Firefox 4 +?

  When using Mozilla Firefox 4.0 or later, drop boxes in VMware Lab Manager are populated is more if it is not possible to deploy new virtual machines.

  It turns out that VMware has released a Lab Manager in August (4.0.4) update that resolves this problem. I upgraded to LM 4.0.4 and dropdown lists are now met again.

• CD Mobile Fidelity Sound Lab (OLA) sound level

  The noise level of the CD any of the Mobile Fidelity Sound Lab (OLA) is very low.  In the OPTION section, I put the volume up, BUT it's still very small compared to the CD standard.  How can I fix so that the MFSL CD have the same sound level as CD ordinary?

  I'm not familiar with these CD. If the iTunes option does not sufficiently increase the volume for you, you should try a third-party tool that standardize the volume to the desired level. Audacity is free, but there are many editors (many of which are free if you do not have to pay for anything whatsoever, unless you really want to) that standardize.  RIP to AIFF format, normalize, and then convert it to the desired format.

  Ensure that the balance is not enabled in the preferences. It can sometimes have unwanted results.

• How can I reactivate produced SRS Labs on Equium A100?

  Hi, I bought an Equium A100-331 and installed XP Professional instead of XP Mediacentre.
  Everything works fine, but I can't find the SRS Labs products as TrueSurround XT for example.
  I did not have this feature. How can I reactivate it or where I can find the tool?

  Thank you

  Hello

  You must install the virtual sound tool Toshiba (V 1.02.01) and you can find it on the download page of Toshiba.

  Help, please

  I suspect that most of the facilities of LabVIEW on Windows consists of LabVIEW 32 bit running on an operating system 64-bit Windows (for the most part, Windows 7, 8 and 10).  As you noted, all the toolboxes have 32-bit versions, and many do not have 64-bit versions (although that is changing).  If you don't need the memory of the large model (and have the memory to support), I recommend sticking with 32-bit LabVIEW.  You will have less room for error and Confusion.

• IEMG analysis with lab daisy

  I'm new with daisylab and I want to make calculations of iemg with signals saved previously.

  (1) I want to resample a signal of 3000 Hz to 1000 Hz

  What is the equivalent of the help (matlab) daisy lab avarage, window or other function?

  (2) how can I calculate the mean values of each 100 samples?

  Here is everything but the last step.

  In the last step, the effective sampling rate is 10 s/s, so the data before and after the peak of 5 ms do not work.

  This is perhaps a good starting point for you.

• Features Windows Lab SMU-1082

  I work in the lab of Windows (so please don't give me all the answers Lab View).

  I have a utility Windows Lab that I support, and I'm doing work on the SMU-1082. We will control the SMU with a MXIe (SMU-8360) connected to a PC.

  One thing I want to do check if the SMU-1082 is connect (or my computer is running it on an ordinary PC).

  I have serached the forums and can't find anything.

  I can not even find any funcitons that can query the SMU box to check something like maps in particular slots (I thought if I ould read if a card is present in a slot, I might be able to use something like this to determine if I was running with the SMU box!)

  Hello Ken,

  If you have downloaded the API NEITHER of System Configuration:

  http://www.NI.com/download/NI-system-configuration-5.5/4086/en/

  You can run the example CVI "ShowAllHardware.prj."  From the finder of the example, it is on "Hardware input and output-->--> ShowAllHardware.prj System Configuration."  If you run this project and choose "localhost" when it asks you to enter the host name, you will get a list of all the devices connected to your machine.  One listed is the MXI Express card that you use to connect to the chassis.

  I hope this helps a bit!

  Happy holidays!

• How to configure a lab overlooking tubular heat exchanger to get data

  HiI

  In our undergraduate engineering chemical labboratory we want to configure our DAq with lab VIEW tubular heat exchanger to get information on the temperature (flow cold fluid warms up), (the steam pressure on the side of the hull of the heat exchanger) and flow (water warms up).

  Can anyone suggest thermocouples, pressure transducers, and flow meters to stay between the heat exchanger and the acquisition of data?

  P.S. the heat exchanger is already equipped with a pressure gauge, thermometers and a rotameter, but we do not know how to connect these devices to data acquisition

  Looks like you have enough information to choose appropriate sensors, you just need to do the research. I start looking into Omega catalogue, or give them a call - they are generally useful. I can't take the time to spec parts for you - it would be a lot of time on another project. Most pressure sensors put a signal 4-20mA or 0 - 5V, that is which you can read through an analog input on a data acquisition; measure a 4-20mA signal requires a resistance to convert voltage. Most NI DAQ boards can read a thermocouple on an analog input, but make sure that your hardware is supported reading thermocouples. For an accurate reading, use a device that has the compensation of cold welding integrated - for example, the block connection SCB-68 - and for more accurate measurements, get a Board specifically designed to measure the temperature.

  For measurement of the flow, a standard, simple solution is an orifice plate. You put a transducer for differential pressure across it, seek the appropriate equations and use them to calculate the flow rate given the density of the fluid (which you will be able to calculate from the pressure and the temperature, since the steam tables are widely available). Other differential pressure devices are available as well - at a previous job, we used a double cone of McCrometer. If you call them, they spec for you - but get an approximate cost first to make sure it's in your budget.

• How to control the current program view lab for a power E3631A agilent

  Hello

  I wrote a program to view lab for agilent E3631A triple output power supply in constant voltage mode, and I want to update to operate in constant current mode also. But I can't find any function in the Instrument of e/s, which is related to the current but only the current limit I already used to write my programs to the constant voltage mode. How can I do this?

  Thank you

  When the current exceeds the current limit, the power supply will be running constant.  The food isn't really have one running constant set.

  Now, I had the indication like that.

  1. in Kethely no indication

  2. in GPIB +'s got orange led in ready icon.

  3 but if I runt the program I found no results.

  So can you me the interfacing of the keithlye and alo for the GPIB and also computer.

  Regads.

  The pilot here can help you. I suggest you first learn how to set up the action manually. Then study the programming guide to understand what commands you need and the settings for them. Good luck.
