HyperDrive 5 and 'fixed Direct Access SCSI-2 device.

Colleagues ESX - ers,

I think to buy a very fast RAM-disk, the "HyperDrive5", in:


It is fully compatible SATAII (and therefore must be recognized by my E200 very well). It is, will be virtualization ESX 3.5 as SCSI drive slow down questions too? My server lists current as disc:

da0: fixed Direct Access SCSI-2 device

da0: 320,000 MB/s transfers (160,000 MHz, offset 127, 16-bit),

Tagged Queueing active

Thus, when you buy the ramdisk, fixed Direct Access SCSI-2 unit of Vmware will be the bottleneck? Or it dimensionnera upward, in speed, according to the new features of the psycical (much faster) of the RAM disk?

Thank you



If it works fine, but SAS, SATA, SCSI and RAM all have different performance characteristics. It will not change the other. The controller will be your factor limiting.

  • vSwitch ESXi 5.1 workaround to virtual machines (direct access to the network)

    Hello world!

    I have a server running properly the 5.1 ESXi hypervisor and got inside the physical grid active router with DHCP. How can I configure the vSwitch on ESXi 5.1 work not managed on the network, without VLAN and have direct access to the network?

    Just to clarify, I would like to first of all virtual machines VMware Workstation works - if it is possible to run several virtual machines and define all NICS (Network Interface Card) as connected by a bridge, that is to say. Each VM gets the specific configurations of IP to the external router.

    Since now, thank you very much for the help!

    Best regards


    With ESXi the vSwitches work comparable to Bridged networking, so there is really nothing special to do.


  • BlackBerry Z10 Spam directly to the PIN device

    Hello, maybe it's a coincidence, but after the installation of pushplane for pushbullet and Blackbullet apps (access to required device ID), I got my first message spam sent directly to my device via its address PIN. Of course, I'm a winner of the grand prize! Concerned about the safety of the phone for the first time. Is it possible to get the PIN reset by BB device?

    Apps have been removed. For access mixture will wait Z10.


    Thank you for that. I did google it and was surprised by the number only. I have always removed apps that seemed to be the catalyst. First time since started using BlackBerry feels less safe.

    Thanks to all for the replies.

    First of all, for later use, you must clear your Event Viewer logs occasionally (your app log has 70 000 + events).

    There are literally has dozens of different errors both on the client side and on the side server.  First step I would run a file system check to verify the operating system (there are probably mistakes)

    When SFC returns clean (not found in access violations) you should post this on Technet (or msdn) because it contains a component of Active directory.

  • Error: "cannot open Volume for Direct access" is displayed when Chkdsk runs at startup

    Original title: Edit/Fix key in my registry

    CHKDSK keeps trying to run during startup, but "cannot open volume...". "If I can solve this problem, I want to put it in the manual, not automatic.      My registry key: "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\rchelp is missing.   Can I remedy this by creating a text file with an REG extension and if so, where can I find the exact measurements to do?  It is the DOS Cmd or in Notepad?

    Hi BarneyBear,

    1 did you allow that chkdsk runs successfully at the start of the system?

    Editing registry is not necessary here. We recommend you to check if the disk check is scheduled.

    This problem can be solved by installing the latest service pack Windows XP.
    See the error message "Impossible open Volume for Direct access" When Chkdsk runs at startup

    See also, Chkdsk.exe or Autochk.exe starts when you try to shut down or restart your computer

  • Just after I turn on the laptop (before that turns on Vista) I get "cannot open volume for direct access.

    Just after I turn on the laptop (before Windows Vista turns on) the following message appears "cannot open volume for direct access.  What this mean and how can it be solved?

    Thank you


    Hi EddieLopezA,

    ·         Which version of Windows Vista is installed on your computer?

    ·         You have antivirus software on your computer?

    This problem may occur if another utility or service, for example a virus check program or a program disk monitoring, locked the partition before you try to run the Chkdsk.exe or Autochk.exe utility.

    I have some steps that may help you.

    Method 1: I suggest you to turn off all third-party applications and check if you have a similar question.

    To do this, follow these steps:

    1. open the start search box, type services.msc and click OK.

    2. in the Services (Local) list scroll the service concerned (for example auditor of virus or disk monitoring tool).

    3. right click on the service and select Properties.

    4. change the startup type to disabled for all applications 3rd - party that could be the cause of the blocking of Chkdsk problem.

    5. click OK/apply.

    6. restart the computer.

    Method 2: If this does not help, try to change the registry value and restart the computer.

    1. click on the start search box, type regedit.

    2. in the Publisher of the registry under the HKEY_LOCAL_MACHINE subtree, go to the following subkey:

    \SYSTEM\CurrentControlSet\Control\Session manager

    3 change the Boot entry run of:

    autocheck autochk * /r\DosDevice\C: (or other)


    autocheck autochk *.

    Note: Change the settings of the REGISTRY can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the REGISTRY settings configuration can be solved. Changes to these settings are at your own risk.  If you want to edit the registry to fix this I urge you to back up your registry before proceeding.

  • blocking direct access to the oracle server

    Dear Sir

    One of our condition of pci - dss to stop direct access to the db. One solution I know:

    TCP.validnode_checking = YES

    TCP.invited_nodes = (, visionhost.solutionbeacon.com)

    But this option will allow the IP address of the node invited with sqlplus using tns names also. Have any have experience to solve the problem of ending up with pci - dss?

    In which paragraph of the PCI - DSS doc that makes you think that there is a problem? I work with version 3.0 (November 2013) and I can't find anything like that. For example, paragraph 8.7 c, "review of database access control settings and application of database to verify configuration settings that the user access directly to the or queries of databases are limited to database administrators" does not say that the DBA is not able to connect to the application server. And all the stuff of firewall in requirement 1 close the access to the network and between networks, not within the network.

    Are you sure that you have a problem? There is no interest to 'fix' something that doesn't have a reference in the doc.

  • Directly access an IP of D-Link camera

    Is it possible to directly access an IP camera. Don't know there is a block that can enter user and password but I don't know what it is. Can someone explain how I can directly access an IP camera in addition to the block is called.

    Thank you


    Hi André,.

    I guess you are trying to access the camera by MAX or LabVIEW. This would require the use of our driver NOR-IMAQdx. Unfortunately, our IP IMAQdx camera support is limited to the cameras manufactured by Basler and axis. Please take a look at the following link for more precision.


    So, I do not think that you will be able to access your D-Link IP camera via our software. I apologize for all that mind which can cause.

  • Access no longer work after the abduction of (Server Essentials 2012 R2) Direct access


    Ive been running around access to the company I work for, its been working well for almost a year.

    I removed a direct access and remote access via the menu "Roles and features" in the Server Manager, since then it is not working and when I try to Config/repair I get a message saying "anywhere access to your server is blocked.

    Ive updated the firmware on the router and the manual configuration of redirection to make sure it wasn't a problem with uPNP port

    Should I check that I can be removed when I removed direct access? Or what I need to change?

    I'm sure I did something stupid...

  • Cannot open volume for direct access?

    OK so I have windows vista 32-bit home... and I installed this program from avg that solves all the problems on the computer... Well now when I boot, I get a cannot open volume for direct access... and I loaded my computer finally and its telling me everything is corrupted?


    I'm sorry but most of the posters, which I am part, who come here do not believe in using Tuneup Utilities, registry cleaners, etc. to improve performance or solve problems.

    They are completely unnecessary.

    Do a Safe Mode system restore to before the problem started.


    How to access Safe Mode



    Or, if you don't have one, borrow a DVD of Microsoft Vista, not a recovery disk and you could do a upgrade in repair facility.

    And I have contacted AVG or their Forums as you say it was their program that caused the problems.
