• High latency LDAP with ESXi 6

  We have Gen9 HP with Emulex 10 GB (driver v10.5.121.7) runs the last 6.0 ESXi and high latency experience above 50ms to 1.5 seconds with LDAP queries between continuous Windows or VM to DC.   However, to move the domain controller to an ESXi 5.5/6.0 with the latency of the network 1 Gb is down to below 50ms.  If you ping just two servers, ping response is < 1ms.

• Tecra M9 - freezes on Windows XP and 7 (with high rotation FAN)

  We currently have 2 Tecra M9 the problem that is described here:

  http://APS2.toshiba-tro.de/KB0/TSB0C032L0000R01.htm

  This also happens on Windows XP 32-bit (Win 7 is a 64-Bit system) and each time with high rotation FAN, the solution written in the KB does not help because after uninstalling the fingerprint software, it still looks!

  But we also have Tecra M9 machines where Windows XP and Windows 7 are running without this problem, a suggestion how to avoid this freezes?

  * Edit *.
  Today same problem with a Tecra A 9 (with Windows 7 64-bit)

  Hey,.

  All laptops have the same hardware configuration, or is it different?

  I think that sounds like a hardware malfunction, so an authorized service provider can help you get rid of this.

  Have you ever tried an update of the BIOS and load default settings?

• Extremely high latency during the migration of the local data store to data store shared.

  Hi guys I hope you help me. Sorry for my English btw, I'm not native.

  Let's start!

  I have:

  1 vCenter
  1 host
  1 Distributed Switch (with a pg for managing network/IPstorage the esxi)
  1 standard switch (empty)
  1 FreeNAS to provide iSCSI LUNS
  1 Microsoft to provide iSCSI LUNS

  When I try to migrate virtual machines between the warehouses of shared data or data shared at local store, all right. The problem has become when I try to migrate virtual machines from the local to the shared data store. All data stores down (all paths down) and back up and I get this error:

  "Error caused by the /vmfs/volumes/volumenID/VMDirectory/Disk.vmdk file.

  
  When I try to migrate virtual machines from the local to the FreeNAS iSCSI data store it fails immediately.
  When I do the same local Microsoft iSCSI datastore that it takes a time loooooong to migrate the virtual computer, give it to me even all the paths downwards and uplinks down error but not lacking in migration.

  I'll give you some screenshots to see the errors.

  Thank you very much!

  EDIT: I have extremely high latency notice when I try to migrate from the premises of warehouses of shared data. average 2000ms with peaks of 50,000 (see my response below for more information)

  Finally, I found the solution! The problem is that I have been using E1000E vmnic instead of vmxnet3. I have configured an adapter vmxnet3 and boom! 20 ms in all migration!

  Thank you to all for help, especially Nick_Andreev !

• HP 15 laptop: atheros wifi causes extremely high latency peaks

  Windows 10 has been the only OS I have used, so I can't speak for others... I noticed that (initially copying files via wifi lan has shown) using wifi really totrures my laptop... it's worse than if the CPU is 100% responsible...  I've updated either, but nothing helps... Tried 2 win10 distributions, but still have the problem:

  Wired LAN:

  

  WiFi LAN:

  

  Even when I am simply navigate using wifi I think it's a torture for the laptop... (and bluetooth it also causes)

  PS (the 2nd screenshot is taken when im close enough to the wifi router) if I get still the wifi router the situation is getting worse (the laptop is fully charged (100% red spikes) without reason...) The same phenomenon occurs with different routers

  (Even though the mouse pointer and the sound almost stop, offset)

  I did a clean win10, install and (instead of downloading drivers from HP myself) let win10 to install the drivers he wants. Now, the problem seems solved! ))

  

  If a device is still 'unknown ':

  

  I presume that it is the «realtek card reader» Maybe the high latency will appear when I intall the driver manually... But I'm not yet... Later if we need in the player card, I'll make if the problem occurred...

  Latest firmware 1.0.02.9. Router has been reset to factory default and firmware has been restored.

  It is made from material? You guys can recommend?

  I think that it is a Wireless Mac driver problem. I've seen this symptom in reverse when ping Mac from another computer on the network. My Mac Mini has similar problems and I have tested a lot of the router. The departure of ping well off the coast and then ramps up really bad and then cycles to good. I have found no solution but my Mac Mini is still usable and the flow seems good, just with a latency.

• X 220 dpc high latency

  Hey,.

  I m very disappointed at my new X 220.

  I ve got dpc very high latency when I m using the built-in 82579LM adapter.

  Sound is stuttering in surfing, playing music.

  With the Wireless 6205, so good!

  What I tried:

  -New Windows install (Lenovo installation clean tutorial)

  -Most recent Intel driver for the network card

  -New Lenovo driver for the network card

  -The powermanager max performance value

  -By default in the BIOS

  All drivers, BIOS, utilities (such as powermanager etc.) and windows are updated.

  Any suggestions?

  
  

• Automatically start vCenter and vms

  Hello

  We have Windows Server 2008 R2 running vCenter 4.1 connected to host computers running ESXi 4.0 Update 1.  Every time we restart the server, the vmware vCenter and vmware vCenter Webservices services start up, they are set to start.  They need to be on the delayed start?  I check the event logs to see what is happening.  Is there a log of vmware that I could look at?

  In addition, we want to implement our virtual machines as the domain controller starts automatically, but I can't find a way to do.

  Thank you

  Mike

  Thank you very much, we are using SQL Express despite 2 virtual machines running SQL Server 2008 :-)  I'm going to the delay value and see.

  If it does not help there are some registry entries, you can make

  http://KB.VMware.com/kb/1007669

  In addition, we vSphere Essentials.  How can I know that if it is configured for high availability and where I see these priorities?

  Essentials does not come with HA.  You can configure your options of start/stop for your guests by going to the configuration of the host tab: start/stop of the VM - properties (upper right corner)

• "the high latency of disk" on the performance tab appears

  Is it normal to have absolutely no activity on the upper Desk of the default latency '1 day summary' tab in vCenter performance? I have the latest updates on vCenter and ESXi 4.0.0 running on my hosts. Guests show CPU, disk use, and use of memory... but zip on this disk latency. We use a copula of IBM Nseries 6040 boxes I think (same as Netapp 3040) with NFS (no fibre channel).

  Since NFS is the network file system and not a block, file system you get not disk performance statistics, it is normal.

• Connectivity issues and touchpad Wi - Fi with Satellite L650 on Win8

  Hello
  I recently updated my Satellite L650 - 18 c (short part no: PSK1JE) to Windows Pro 8, thanks to a commercial copy. The laptop works very well and I am happy with the new OS, but I have a few problems.

  1 - Touchpad
  During my first installation of Windows the touchpad used generic drivers, then I went [here | http://pt.computers.toshiba-europe.com/innovation/download_drivers_bios.jsp?service=PT] to download the proper drivers. I couldn't find the drivers of Windows 8, so I went to the Web of Synaptics site to get the drivers directly from there. I got Windows 7 drivers.
  When I try to open the settings for the touchpad in Windows I get an error that looks something like "Unable to connect to the Synaptics pointing device" and I have to reinstall the drivers.

  2 - wireless
  I high speeds (~70Mbit/s) with an Ethernet cable, but Wi - fi, I only have 3.5Mbit / s.
  I read that this is related to the drivers, so I looked up the proper drivers, but so far found no one who even settle (I click Yes on UAC and then nothing happens).

  I really want to avoid going back to Windows 7.
  Is there something I can do?
  Any help would be much appreciated.

  As a first step, you should check if your laptop is supported for Win8 or not. Do it on
  http://EU.computers.Toshiba-Europe.com/innovation/JSP/checkWindows8Compatible.do?service=EU

  If this isn't the case, then you can try to use the drivers for the recent but similar laptop models.

  WLAN I checked the specifications of the laptop and your laptop has WIFI and Bluetooth combo card. It is Wifi b/g/n 11 + BT V2.1 + EDR (Broadcom BCM94313). Unfortunately the Toshiba WLAN portal you won't find Win8 drivers at the moment.

• Qosmio F30-140: Vista stopped and I heard a very high noise

  Hello everyone

  Really, I have a big problem
  My operating system is Windows XP media center 2005 and it is written above (Designed for windows xp, Windows Vista capable)

  2 last week I had installed windows Vista ultimate 32 bit and pilots of the Qosmio, but after 2 days when I worked in Microsoft office Word, the system stopped and I heard a very high noise of it (maybe the processor or fans) but he was really scared and immediately, I turned it of the power button.

  This problem occurred 4 times through this time. I had installed windows xp again from the recovery disk and there is no problem and I installed Windows Vista again hard night but today in the morning the same problem again.

  I don't really know how to fix this and I look forward to receiving help from you.

  Hello

  It s certainly nothing wrong with the firmware Toshiba VAP this nothing to do with your question, you issue sounds more like an overheating problem the OS freezes at a temperature inside the laptop.

  Probably don t cooling modules run a full implementation because of the dust and debris inside the laptop.

  The second reason why a laptop could overheat is the graphics driver installed _non-Toshiba_!

• If you run the program Setup 'Run as Administrator', executable runs with high fees?

  Hello

  Installer of LV chose "run the executable at the end of installation.
  If you run the installation program "Run as Administrator", the executable runs with high fees?

  Best regards

  My apologies - configure when the installer to "run the executable at end of installation", it will run this executable with the admin rights because the installation program itself requires administrator rights.

  LabVIEW installation program can create registry keys for you.

  For your more advanced customization (e.g. selection modules), you have to look different (e.g. InnoSetup) using a solution of installation or you would need to write an executable in LabVIEW that you run after installation that allows you to select the Setup programs you want and run them using System Exec.

• The most effective way to log data and read simultaneously (DAQmx, PDM) high data rates

  Hello
   
  I want to acquire the data of several Modules cDAQ using several chassis to
  high data rates (100 k samples per second if possible). Let's say the measurement time is 10 minutes and we got a large number of channels (40 for example). The measured data is written to a PDM file. I guess, the memory or the HARD disk speed is the limits. For the user, there must be a possibility to view the selection of channels in a graph during the measurement.

  My question: what is the best and most effective way to save and read data at the same time?

  First of all, I use an architecture of producer-consumer and I don't want to write and display the data in the same loop. I expect two possibilities:

  [1] to use the 'DAQmx configure logging.vi' with the operation 'journal and read' to write the data to a PDM file. To display the data in a second loop, I would create a DVR samples documented and 'sent' the DVR for the second loop, where the data will be displayed in a graph (data value reference). This method has the disadvantage that the data of all channels is copied into memory. Correct me if I'm wrong.

  [2] use 'DAQmx configure logging.vi', but only with the "journal" operation to write the data to a PDM file. To view the selected data, I had read a number of samples of the TDMS file in the second loop (I'm currently writing the TDMS file). In this case, I have only one copy data from the selected channels (not), but there will be more HARD drive accesses necessary.

  What is the most effective and efficient solution in this case?

  Are there ways to connect and read data with high frequencies of sampling?

  Thank you for your help.

  You say that the measurement time is 10 minutes. If you have 40 channels and you enjoy all CHs at 100 kHz, it is quite a number of values.

  In this case, I always try to approach under the conditions of use. If a measure is only 10 minutes, I just connect all PDM data and create a graphic module that could be in the same loop of consumers where connect you the data. You can always work on the raw data files big offline afterwards, the extraction of all the information you need (have a look at the product called NI DIAdem: http://www.ni.com/diadem/)

  The main issue is that the user needs to see in the graph (or perhaps a chart can be useful too). Lets say that the graph is 1024 pixels wide. It makes no sense to show multiple data to 1024 points, Yes? Every second will produce you 100 data points k per channel. What is the useful information, which should see your username? It depends on the application. In similar cases, I usually use some kind of data reduction method: I use a moving average (Point by point Mean.VI for example) with a size of the interval of 100. This way you get 100 data points of 1000 per channel every second. If you feed your graph every second with these average values, it will be able to data points in 1024 of the store (as a default) by channel (curve), which is a little more than 10 minutes, so that the user will see the entire measurement.

  So it depends on the frequency at which you send data to the consumer. For example, collect you values 1024 by iteration of the producer and send it to the consumer. Here you can make a normal means calc or a bearing (according to your needs) and he draw a graphic. This way your chart will display only the values of the last 10 seconds...

  Once I programmed some kind of module where I use a chart and not a graph, and the user can specify the interval of the absolute timestamp that is traced. If the data size is larger than the size of the chart in pixels, the module performs an average calculation in order to reduce the number of data points. Of course, if you need to see the raw data, you can specify an interval that is small. It all depends on how you program zoom functions, etc... In my case I hade a rate of 1 Hz, so I just kept all data in RAM limiting the berries to keep 24 hours of data, so that technicians could monitor the system. In your case, given the enormous amount of data, only a file read/write approach can work, if you really need access to all of the RAW data on the fly. But I hope that the values of working capital means will be enough?

• Canon 6 d noise long exp with high iso speed

  Hello

  I would like to know the 6 d can I adjust on the noise of long exp with high iso speed and raw?

  Thank you.

  If you mean high ISO NR Don t speed you should use it with raw. I know that he doesn´t whether you have enabled or disabled. Only if you shoot jpg.

  With raw, you can still enable or disable high speed ISO NR in Canon's Digital Photo Professional or noise reduction in another raw converter.

  

  As written TCampbell long exp. noise reduction will take two images and remove all hot and dead pixels. RAW converters often have stripper hot pixels.

  Another thing to do to make less noise is to keep your cold camera sensor. It's in Swedish, but you will understand the temperature in degrees Celsius. Live view mode will heat the sensor, so Don t use Live view for minutes before taking a longer exposure. You can check the temperature inside your camera with an exif viewer. I Don t know where inside temperature is measured.
