Question on the iSCSI initiators and several NIC

I read the attached document.

The document speaks to create more iSCSI initiators to talk to the SAN (I understand this bit).

Page 15 step 4: VMkernel Ports associated with physical cards

The document speaks about 3 network cards that have been attributed to a vSwitch.

The document then continue to talk about the creation of links to individual access to a network adapter for each VMkernel path.

My question is:

Why do this?

Why not create three separate vSwitches and create an initiator iSCSI for each vSwitch?

VCP3 & VCP4 32846

VSP4

VTSP4

Why would you not create a vSwitch for each iSCSI NIC and VMkernel port. Why the document insists on putting all the NIC in a vSwitch?

The number and type of vSwitches is not interesting.  You can use a vSwitch or vSwitches as much as you have physical NIC.  It works as well for the former two vSwitches static or vDS.  The configuration example is just one of the ways that you can do.  Any combination is supported.

  • question on the layer effects and filters - Jews Becker

    Hello

    I have a question about the layer effects and filters

    first is there a way to layer effects in flash (as in photoshop 'coup' "outter glow" etc...)

    so it is a kind of plug-ins to special effects - perhaps with particles or pretty effects that I can buy

    Thank you very much!

    (as you may have guessed I'm very new at this and appreciate all the advice I can get!)

    -Jews Becker

    You won't find anything exactly like filters in Photoshop for use in Flash. There are filters in Flash. They are available at the bottom of the Properties window for an object MovieClip or button on the stage. Alternatively, you can apply and animate a filter in Actionscript. There is a good third-party developer, http://www.greensock.com, where you can find a few effects tools very useful. Most are free.

  • How to lock the scroll bar and several tabs to prevent them from scrolling erratically

    I have upgraded to Windows 10.
    Now the fireplace (Yes, it's the latest version) scrolls top down in erratic Web pages.
    I can't control the right scroll bar.
    Even after clicking on it or by moving up and down, either with the use of the touchpad, arrows and arrows at the top / below the scroll bar itself, it moves just everywhere anywhere on the page.
    The same thing occurs when multiple tabs are open. They scroll left and right erratically.
    Help! It's the most boring, frustrating and time consuming.
    I have already searched several forums and blogs, disabled the auto-scrolling and scrolling soft, all to nothing will do.

    On my system, the mouse pad has a mind of its own. So I opened it from the

  • FPGA reference questions between the station development and execution? 63195 error code

    I will do my best to describe the problem, I was see.  Note, I tried a few other messages that kind of touch on my problems, but they never seem to have a definitive solution.

    Background-

    I have 3 screws:

    VI 1) opens / runs the bitfile FPGA reference and stores the reference to a global file so that I can call the reference of other screws I need to do this as opposed to the opening of a new reference because I use the FPGA for digital communications and it adds about 100 ms to to open a new reference whenever I need to read/write in the target FPGA to host (100 ms are long in the) digital world!).  Some people use Shift Registers.  I finally called my whole army FPGA screws of TestStand to run a test automated, so it was easier to break up of my functions for open/close/read/write.

    VI 2) called the global reference of the file for FPGA, then going to a read/write node to change the settings of the target, then passes the reference out of the node back to the global reference of the file read/writable

    VI 3) calls close reference FPGA and the function is passed the global reference of the file.

    Question-

    I understand not why this method works fine when I run either of TestStand with station options defined for the development (not running) mode or when I open VI which calls these 3 screws individually in sequential order but IS NOT working when I try to run these screws individually (Run VI 1 - open-> write Ref to the global reference of the file-> Run VI 2 - read global file reference-> playback control function / writing-> error-63195) or when I have run in the same sequence TestStand but together with station for execution options.  Maybe I need to change the TestStand sequence to load all the modules at startup?

    Why the reference becomes lost when global failover between development and execution and why labview cannot drop keep the reference stored?  Is there a work around?

    Finally found a solution.  I do not understand why it is necessary during the reading of the FPGA and not what writing (in fact I do not understand why it worked at all) but I ended up changing the properties of the step in my TestStand sequence for the step calling my DTL_READ.vi to be properties-> Run Options-> Unload Option-> "Unload after executing the step.  That seemed to do the trick to get my test TestStand sequence to work in runtime.

    I still don't understand why this was not required when you run the same sequence in the design environment and why it is not when I call my DTL_WRITE.vi.

    The DTL_READ.vi and the DTL_WRITE.vi pass the parameter labveiw global.vi 'Reference FPGA VI"of a node in read/write.  I don't know if the root of the problem is in my host TestStand and LabView FPGA VI...

    Thanks for all suggestions from you guys!  I'm happy I work but I am still confused by the solution.

  • Questions after the BIOS updates and driver - place 11 pro

    Hi all

    I am owner of a place of reference dell 11 7140 model 10 64-bit windows running and about 5 days ago I installed the latest drivers and the latest version of the BIOS using the automatic detection of the dell support page www.dell.com/.../drivers printer driver

    Since then, I met the two following questions:

    1: the automatic detection of the dell driver no longer works

    2: the system does not detect when a headset is connected, the audio always comes out the speakers Tablet - I reinstalled the latest drivers, but made no difference

    I wonder if anyone else has experienced those problems and what measures have you taken to solve problems.

    Thank you

    I managed to solve the problem with the audio: it was caused by an incorrect realtek driver installatiion, for some reason any 'Realtek Audio Manager' was not loaded when you start and that's why the system doesn't detect the status of the audio input jack.

    Always have the question of the automatic recognition of the driver, but at least I have a tablet of new work!

  • Question about the memory consumed and active

    I have esx4.1 on three dl585 running. I have about 100 active vm running, and I have a small question.

    My vm is all 2008 r2 datacenter and I gave them 1 cpu and 4 GB of ram. When I recover a single virtual machine and look at the summary page, I see the bones of memory consumed host 4075 mb and the active guest memory 81 MB operating system. My question is can I reduce the host cunsumed memory to 2 GB without noticing a difference within the virtual machine?

    It looks like you can.   To be absolutely sure that you'd need monitor assets long enough to have a good idea of what the average is and what are the tops.

  • Quick question on the button symbols and simple roll overs

    I'm prototyping bee my last several websites in Fireworks in front of her a coding in Dreamweaver. I see two ways to accomplish the same thing and wonder if there is any advantage to one or if it's just a user preference of how to do it.

    When you create a single roll on it seems that this can be done in 2 ways:

    (1) create a slice around the image, and then, in the range, select creatte a behavior simple reversal.

    (2) convert the image into a button symbol and then change the symbol to add more force.

    Both are simple ways to do so. There their advantage to one or the other?

    Fireworks is more powerful, while many think. Not always the best code bit large layout and comping tool!. While you work more with web pages, you can learn how to make CSS based menus in Dreamweaver :-)

  • Question about the game database and the UNICODE character

    Hello

    I have to configure a database for an IBM product where is a requirement:
    "Databases must be created using the UNICODE database and National characters as UTF8 games, AL32UTF8 or AL16UTF16 or."

    My current database character is: WE8MSWIN1252. Change the current database character set is not an option, so I have to create a new db for this requirement.

    My question is:
    (1) how to ensure that "databases must be created using the UNICODE database"?

    (2) to take care of character, I'll use in the database creation script:

    "

  • Question about the Apple Watch and tattoos

    I think buy a Apple Watch very soon.

    I have a full sleeve (which is where I would like to wear the watch) and I wonder if it will cause problems with readings with the heart monitor since I want to use the Apple Watch for fitness training, mainly.

    I read on the page of the heart rate for the saying of Apple Watch:

    "Permanent or temporary changes to your skin, such as some tattoos, can also impact performance heart rate sensor. Ink, model and the saturation of some tattoos can block light from the sensor, making it difficult to get reliable readings. »

    There are other problems in addition to playback of heart rate on the Apple Watch for inked people that may know you?

    Thanks for your comments just to decide if this watch will really be for me before making this purchase, because I missed one for some time.

    If you are looking for, there was a very long discussion about this in the past, only shortly after the release of the Apple Watch. What I've read, it seems that the heart rate monitor is the only victim when it comes to the watch, since this is the only thing that requires the sensors to work through ink. Not all inks makes a difference, but most don't. The activity of exercise/app also uses the heart rate monitor to determine the rate for the year. You can take the time to go to the nearest Apple Store and try on the Apple Watch and see if the monitor works with your sleeve.

  • Question on the recovery CD and the Vista anytime upgrade

    Hello

    I bought a toshiba laptop now a year ago, it came pre-installed with vista home premium.
    I would like to do a complete cleaning my system as its useless been lately and isn't a fact since I bought.

    It came only with - a the product recovery disc and upgrade Express windows.
    But I'm worried because if I do a recovery of product I don't have the real vista disk it SHOULD have and will not have vista on my laptop or one of the files that toshiba put on it.

    What should I do?
    What a product recovery disc actually have on it and do? What is the Windows anytime upgrade disc?

    I have been informed by microsoft and I.T. technicians everywhere that i should have a vista installation disc in the same area so the fact it came pre-installed.

    Help, please

    > It came only with - a the product recovery disc and upgrade Express windows.

    As you say you have the product recovery disc.
    This Toshiba drive contains the image of Toshiba.
    The image is a package and it contains the operating system Windows, Toshiba drivers, tools, utility and software further.

    The use of the recovery CD will fix the laptop back to the factory settings.
    So just boot from the recovery CD and follow the instructions on the screen.

    Just for info:
    The recovery CD will format the whole HARD drive, but I see that a backup is not important to you.

    See you soon

    Hi all.  Firstly a bit of background.  I am a former admin of system IT I got a C240 as a gift.  I tried to remove the music from Windows Vista section of the computer where the C240 is listed as a portable device.  Now, I can't get things to work quite right.  I seem to have the 8 original songs/5 albums that come with the device.  The number has doubled to 16, and half of them cannot play.  I'm not sure I want to do with this device, but I want to clear in addition to all the current music and load my own.  I tried to download the update of the firmware and it still just waiting and never took the screen "search for updates".

    Also, I have Media Player 11 and it does not recognize the unit.  So, how do Media Player to see the device, copy music to it and delete the prepackaged songs accompanying?  Any help will be appreciated.  I don't want to choose the format from the settings menu, unless it's the way to go.  Arrest me please make any more mistakes!  Thanks in advance for help a dummie MP3!  -Victor

  • Question on the composite index and index skip scan

    Hello
    I have a confusion.
    I read the post of Burleson on the column of the composite index command (http://www.dba-oracle.com/t_composite_index_multi_column_ordering.htm) where he writes that

    «.. . for composite indexes the most restrictive value of the column (the column with the highest unique values) should be made first to cut down the result set in... »


    But 10g performance tuning book tells the subject INDEX SKIP SCAN:

    "... Index scan Skip allows a composite index that is logically divided into smaller subindex. In Dumpster
    scanning, the first column in the composite index is not specified in the query. In other words, it is ignored.
    The number of logic subindex is determined by the number of distinct values in the first column.

    Skip scanning is advantageous if there are few distinct values in the main column of the composite index and many distinct values in the key do not tip of the index... »

    If design us a composite index according to what said Burleson, then how can we take advantage of index skip scan. These two staements to oppose each other, Don't they?

    Can someone explain this?

    Even if you're not skip scanning, it is best to put the column with less distinct values in the main column of the index.

    If a query specifies two key as predicates of equality columns, it doesn't really matter how columns are sorted in the index.
    If a query specifies a range on a key column, it is most likely on the second column of the index.

    BTW, sometimes even a column 3 or the index of the column 4 is useful. In order to not restrict simply yourself in 2 columns. However, do not create too many clues - especially if there is overlap between the index.
