• output voltage DAQ for external device control

  Hi all

  I have been using LabView 8.5 to acquire data from an acquisition of data USB Multifunction (1608FS of MCC DAQ) module.  However, I now want to use this device even for controlling an optical shutter, but also to detect the position of the shutter sensor.  Is it possible using this device in LabView?

  I had no problems on the side of the acquisition but I was not able to generate any output voltages can any body in this case help.

  Concerning

  Steven

  According to my quick google search, this device is listed as

  DAQ module with eight 16-bit analog inputs and eight e/s digital

  So there are no outputs only digital outputs.

• Help to configure storage for vSphere 4

  Hi all

  I am designing the datstores for our new vSphere installation.  The virtual machine will be Windows servers with a default configuration of a logical drive C and D.  Some servers will have additional logical drives.  Some of the team think that it will be better to place the virtual disks for the C drive in a single VMFS volume, while placing the D virtual disk drive in another.

  Are there performance problems or advantages with this configuration, or is it better to store all of the virtual disks associated with a virtual machine in the same data store?

  If we divided the VMDK in different datstores could this affect pagaing if the pagefile is stored on the logical drive that D?

  Storage is a HP EVA 4400 with SAN disks (which is currently proposed to store the virtual disks of drive C) and a 1500 (SATA) MSA (currently proposed to store the virtual disks for drive D).

  Thanks for your help

• Remove the inactive storage for vSphere

  Hi all

  I need to delete some idle of my installation of vSphere storage. I removed before storage, right-click on the storage and choosing Delete but I don't have this option either available, I guess because the storage is inactive.

  There is no chance of this more active storage yet, but for administrative reasons, I want to remove it.

  For the registration of all hosts are the ESXi.

  Thanks for the pointers,

• Cannot find the specified device, path, or file. May not be the appropriate permissions for access you.

  Hey everybody,

  I was running Windows vista professional for more than 2 years yesterday, I formatted my hard drive and reinstalled vista prof. (entirely new, different CD key). Everything works very well excenp for one thing - I had saved some of the programs and files on my external hardrive before formatting my laptop. Now, when I try to access these files I get the following msg-"cannot find the specified device, path, or file." You don't have permission to access them. ".
  I am logged in as administrator.
  
  
  Help, please. I reallly need the files.
  
  
  Any help would be appreciated.
           

  Hey Jihirshu,

  It looks like permissions.

  Try this on one of the files on the disk to see if it allows you to copy the files.

  1 right click on the file, then select Properties
  2. click on the Security tab
  3. click on change, in the name box, type "Everyone".
  4. in the boxes next to the permissions below, put 'Total control' for everyone
  5. click OK, and then close the dialog boxes
  6. try to copy the file that you just modified.

  If the works above, you must change the permissions on all the files you want to copy.  Normally, you can just highlight all the and follow the steps above to change the permissions on all files at the same time.

  Hello
   
  1. don't you make changes before the show?
  2. is the computer is joined to the domain controller?
   
  You can not start any application on a client computer that is joined to the domain controller. When you try to start this type of application, you receive an error message similar to the following:
  "Windows cannot access the specified device, path or file. You can not have the appropriate permissions to access the item.

  This can also occur if the user account is damaged. If the computer is not connected to a domain controller, try the following steps.
  1. connect to another user account and create a new user account to fix the damaged user account.

• Writing files apps get the "Windows cannot access the specified device, path or file. May not be the appropriate permissions for access you the items"error

  It only occurs with certain applications. Firefox and steam (the game application), for example.

  He regularly happening when trying to download a file with Firefox, regardless of the folder I tried to save the item to. Helped Disabling UAC. Sometimes, even when from time to time, however. I usually just download the file again in the same place, and it works fine.

  With steam, it happens 100% of the time when he tries to update. I am trying to troubleshoot with them, but I strongly suspect that there is an underlying problem related to Windows. I am running Windows 7 Home Premium 64-bit.

  It may be relevant that all my files have the blob (not checked) in the box 'read only '.

  There has been no recent changes to my computer.

  I tried:

  Creating a user profile. The question persists while the user as well.
  Using the attrib command from the command prompt to reset the properties of the folder.
  Run the checker system (no errors found) files.

• Add crash function storage for wizzard in vSphere Client 4.1

  Hello

  I separatelly that install ESX 4.1 on HP DL380 G6 with 2 logical drives on SmartArray P410i, first storage was created during the installation process.

  And when I try to add (second storage) storage in vSphere Client wizzard breaks down with configuration of host error, please what I m doing wrong?

  

  Thanks for any help

  Jerome Kovac

  I saw another post there, someone had a similar problem because they had a few other partitions on the disk.  They have manually deleted these partitions with FDISK and then managed to format the volume normally using the wizard so could be a potential cause of this?   Deletion and recreation of the second virtual disk must also remove all partiions.

• Differences between the ISCSI connections to the storage in vSphere 4.1 and 5.0.

  I'm in trouble of setting up the connections of storage in a new VSphere 5.0 test environment. In our environment VSphere 4.1, it was possible to create a virtual switch add two Broadcom NetXtreme II 5709 NIC. Set assets. IP Hash value as load balancing. (LACP Etherchannel on physical switches) This configuration uses a grain port and a single IP address. Then add our NetApp NFS storage and ISCSI Equillogic storage. In VSphere 5.0, I can't create this same configuration. I have to create separate with separate IP addresses vmkernal ports? The idea was to have redundant connections to the storage and flow of these two NETWORK cards. Possibly adding additional if necessary to the futuer NETWORK cards. Any help with this would be greatly appreciated.

  How can I work around this:

  "VMkernel network adapter must have an active link exactly and no waiting rising to be eligible for the iSCSI HBA connection."

  I can certainly say that the way which allows you to configure the iSCSI Multipathing is incorrect.

  The main idea is to let Native Multipathing Plugin to decide what network path to choose, not the vSwitch.

  At the level of the network layer, you must have 1 VMK by a physical NIC.

  This technique applies as well for vSphere 4.1 and 5.0, but with the 5.0 it is configured easier and more quickly.

  Here's a very brief consequence of steps

  1. get 2 VMK interfaces and assign an IP by each VMK.

  2. set each VMK to use only one physical NETWORK adapter

  3 GB with storage iSCSI software adapter, turn it on and bind your VMKs 2.

  4 connect to your iSCSI storage space

  5 rescan devices, create the VMFS datastore

  6. set the desired load balancing VMFS method or just set up a prior default create new VMFS

  Hi Surya,

  No, it's not any problem with the configuration of your path.

  It only means that this policy does not allow additional configuration.

  I.e. with fixed NMP, you would be able to configure a preferred path allowing you to manually distribute the i/o load.

  Your current configuration does not offer this option.

  Kind regards

• Storage for Lab Manager

  My client needs storage for Lab Manager running on 100 servers. Is it recommended to use the NAS or SAN for Lab Manager running and what type of e/s that you wait for the same thing?

  I did a little bit with storage of LM in recent years.

  I have a development/test environment on LM 600 machine, using 2 Sun 7210 storage devices (is no longer available) on NFS shares. We have 2 links 1 G servile vmKernel traffc as well as links to more vmnetwork, management, etc.  The devices are related to links of 4 x 1 G each.

  I don't know what are the current constraints of LM/ESX, but whenever we revisit the decision 'block vs NAS' we end up selecting NFS (our Sun boxes can present the iSCSI as easily).

  As Jon says, what storage you need certainly depend on your VMS and load.  NOTE: my experience is * NOT * in a production environment, where I am squeezing virtual machines performance.  It's more about the functionality and "adequate" performance (where "adequate" is a measure based on the user experience topic).

  Some things we have learned over the years:

  • IOPS / s are kings, and most of them are entries.  (Written at the moment, I have a few heavy ready operations push me down to about 65 percent.)  I saw > 80% of entries maintained for days.)
  • Latency does not seem as important - VMs run about the same at 10ms latency and latency 250ms NFS NFS.  When latencies above 750ms grows, they will be noticiable users and if they go more than a second over 1000 ms you will begin to see the impact on the guest OSes, especially Solaris x 86.
  • Normal operations don't care about bandwidth - just current execution machines don't even fill a link 1 G
  • Deployment operations * could * start filling to the top of the bandwidth, maybe
  • Betware storm IO.  Often people think the storm IO deployment/boot, but 400 RedHat machines all the kickoff of their 'updatedb' cron job at 04:00 can produce any IO storm as well.  NOTE: IMHO if you buy storage to handle this kind of thing, you're overpaying storage.  I've spread my cron through the night and now can not see on the graphs of storage performance.
  • There is * NOT * a good correlation between guest OS IOPS / s as shown, for example, iostat and PAHO are / s NFS presented to the storage system.  I'm guessing that ESX made a lot of caching.

  Most storage vendors I spoke last year does not seem to find it.  They think in terms of bandwdith and it accelerates with read cache, so unimportant in my environment - I had to push really hard to get sellers to think in the right conditions and some of them really seem out of their depth there.

  I think that this state of mind is important: consider the IOPS / s as you consider CPU: how much should I give to each machine?  How much should I oversubsubscribe?

  Like CPU, a physical machine which IO a lot more available that he needs and you can consolidate - but don't know how.  A physical machine with a pair of 15 k drives RAID1 has about 200 IOPS / s available and readers spend most of time inactive (a bit like the CPU).

  That will boost the machines and when?  Right now I'm on average 9 inputs/outputs by VM, which in my opinion is quite small.  My storage system can go higher under request, but I have enough machines that it is fairly constant.

  In my quest for the perfect storage of LM, I found the usual: good, not expensive or fast, you can choose any two.  How we use LM (lots and lots of shared models) we would really like a unique namespace shared (i.e. 1 data store). I have yet to find the 'perfect' - storage, the Suns are very profitable for the performance and space, but their management takes too much of my time and my 72XX are not expandable - the 74 might be a different experience.  I am currently looking to add some SSD storage, but the ideal configuration would be automated migratino between levels (for example, EMC QUICKLY) and if I bought only from EMC I would triple my cost per VM.

  I talked to people who have a pattern of use of different models that are quite happy on several data stores.  If you can move your load through many warehouses of data then Isilon looks like interesting storage.

  So, in summary:

  • Watch IOPS / s 1st, 2nd and 3rd, then the latency time, then (maybe) bandwidth
  • Manage the budget or the ability of the IOPS / s as you CPU
  • You may not use comments IOPS / s to provide shared storage IOPS / s

  I'm hoping to have a better storage solution in the next 6 months or more.

• I try to use my Time Capsule as external hard drive. But when I look in the Finder, nothing is available for shared devices.

  I have a Macbook air running OS X El Capitan. I try to use my Time Capsule as external hard drive. But when I look in the Finder, nothing is available for shared devices. I don't know if I need to restart the time Capsule or change the wireless setting, etc. ?

  Please advise...

  The TC appears in airport utility? If not then it is probably not part of your network or is lost... upgrade installed you El Capo because there a lot of questions.

  What is the TC plugged into the network by ethernet? And configured properly? Are you to internet via the TC... but can not see his drive... that would be typical?

  Have you set Finder preferences to display the network drives? Apple keeps making it difficult for some unknown reason.

  You actually have to mount the drive TC if it appears under shared... it still may not appear if you double click on it. Under the search box on the top of the right hand you see Connect (As) box, type the name or IP address of the TC in there... Make sure that you save the password from your keychain.

  I try to use my Time Capsule as external hard drive

  For the storage of the files it is fine.

  For the execution of direct files for an application in the Mac, you are very likely to damage or corrupt the file at some point.

  And how do you do backups? Time Machine can't help you... it won't work.

  Backup is crucial, especially if you do things apple say not to do... That is to say move your photos or the iphoto library to the TC and try to use direct from there... expect any day to need a resumption of the library.

• Do you have an iCloud account or an account for each device purchased iCloud?

  If they use all the same ID, then 5 GB. If you use a different iCloud for each device ID, 5 GB each.

• How to manage the parameters of storage for my iPad?

  I get an error message that my iPad storage is almost full; Yet, I still have 177GB available in iCloudl

  What should do?

  Thank you, Kay

  iCloud-storage is not the physical storage that is ACTUALLY on your iDevice.

  If your iPad is almost full, if you have something important that you want to keep on the device, you must back up these data with iTunes on a computer, or the value up/backup these data iCloud or some other "cloud" off site server storage service or something like DropBox.

  OR buy a local, mobile, storage devices as WiFi enabled portable hard drives for mobile devices or active Wifi USB flash drives store your iPad data locally.

  Then you can selectively decide what you need to delete out of your iPad to gain, to free up space for data storage.

  Good luck!
