best practices for adding 2nd drive Windows VMS on SAN

If I have a VM on an Equallogic SAN and want to add a second drive letter I will add it as a second file VMDK for this virtual machine, or I should have the BONES of the VM (Windows 2003) use the built in iSCSI initiator to turn up the volume on the SAN?  What are the advantages and disadvantages of these methods... or am I totally wrong in how I think these work

Thank you

With the help of a second disk vmdk will give you much better performance because iSCSI has a much higher latency and adds a layer of complexity that is not necessary.  More then send iSCSI traffic on your network that add overhead.  I strongly suggest you simply add a new vmdk.

  • Best practices for adding form fillable form designer EULA & forcing acceptance by the user

    What are created the best practices for adding a license agreement end user to a form with LiveCycle Designer. and to force the user to signify the acceptance of the EULA before access inside the form?

    Time, I have the kludged with a series of four message boxes (which is necessary because my LICENSE agreement, like most) is too long to fit in a single messageBox).  3 first message boxes have OK/Cancel buttons.  If the user clicks OK, she gets the following message EULA box; If she clicks cancel the form closes.  The last post (fourth) area a Yes/No buttons with the corresponding behavior.  It seems that the work (I think?), but it's ugly.  Is there an "easy way" to do it with a single drop-down dialog box "I agree" and "I refuse" custom buttons?

    I've seen references to Tools like this but they are marked as obsolete or abandoned due to security or other unspecified concerns.

    Best, Blake

    Another way might be, keep the form pages hidden at the beginning and only display a single page that has text box that contains the EULA with accept and refuse to scroll buttons. IF someone refuses, you can keep the rest of the hidden form or display message boxes to force acceptance of the EULA.

    If anyone agrees, you can simply hide the EULA page, and display form pages.

    I hope that used here too scripting required to reach it either.

  • Best practices for adding text to the Flex container?

    Hello
    I'm having problems to expose a TextFlow class correctly inside of a Flex container. What is the best practice to achieve, for example adding a lot of text to a small sign?
    Is it possible to do anything other than static width and height DisplayObjectContainerController constructor, or is - not the place to implement this? I guess what I'm looking for is the logic of the layout, I normally wrap in a custom Flex component and implement within Measure [] and so on.

    My use case: a chat application that adds several elements TextFlow to a Flex for example the Panel container. Or use TextFlow substitute UITextField.

    Examples of code would help me greatly.

    I'm using Flex 3.2.

    Kind regards

    Stefan

    You are right, the examples we have provided are specific to TLF, an ActionScript component, rather than a Flex component. Flex Gumbo is implementing what I think you are looking for (a UIComponent to TLF). Gumbo is still under active development, we chose to stay with examples that apply as much 3.2 Flex Gumbo.

    Check out mx.components.FxTextArea; I'd be curious to know if it's the 'start of market' looking in terms of using TLF in Flex.

  • Best practices for adding video

    Hello. I designed a nice app with several slide shows that has been rejected due to lack of interactivity. I am now in the process of planning for multiple short videos and audio files to add in it.

    To test the video feature I used handbrake to turn a video at a resolution of 330 x 178 MP4 h.264. (I'll probably do the final versions on 400 horizontal.)

    I used the command set and in the preview of the content viewer, it seems fine.

    (1) using the media Panel, you can choose the poster come from a current frame, but this does not add the symbol Play so app users he might think a static image. It is my only option to do this is to create my own poster and add the Play symbol on the top or is there a built-in way to do this?

    (2) my app pages have white background. Aesthetically it is 'bad' placing the video directly on it. Should I create just a big black rectangle for each video to give it a border or is there something else to make it look professional?

    (3) the media group has also a controller which I assume to set the video playback controls, but everything I select does not seem to make a difference. I have also used Lynda but have not found an explanation. What is doing?

    (4) I saw the soft of my 9 months made by forum MVP Bob Levine. When it turns to a new page a button pops out with a microphone. symbol when you press return audio plays. It looks pretty nifty. If this isn't a trade secret how to get the button out?

    Thank you

    1. I generally create an image of the poster with this symbol of game. Pretty easy

    to do. Open the video in Photoshop, go to the section you want, add the

    symbol and save it as a PNG file.

    2. If it looks good, it's good.

    3. If you really want the video I suggest the creation of control buttons

    and by assigning video shares their

    4. those are three State ESM. The first State is a sequence of images with

    go to the next State button. The next State is out pop glossary

    containing a framework placed MP3 files scrollbar with anchored above the

    terms. The close button will take you to a third State with a version of the State

  • HP stream 11-d008tu: best practices for migrating to Windows 10?

    Hey there, I have a HP flow 11-d0008tu and received the notification I can upgrade to Windows 10. I want to do a clean install with a downloaded ISO but knowledge first of all, it is better to upgrade so that you get the activation done.

    Can someone give me some ideas on best practices for the upgrade? The stream has only 30GB HD so I have no recovery disk, I'll just do a recovery later on USB or SD card. When I do the upgrade can deselect recovery option or delete?

    Also, any other suggestions appreciated, especially which helps make effective for small HD

    See you soon

    Hi, I posted an installation procedure for Windows 10 fresh for the Tablet HP Stream here.  Also, I have a laptop 11 flow but do not have that yet. I think it must be the same because they both the same drive of mem 32 GB Hynix. A change would you probably want to use the 64-bit instead of 32-bit Windows 10 ISO file, the Tablet has only 1 GB of RAM.

  • I would like to know the "best practices" for unplugging my computer permanently to the internet and other updates.

    Thank you for taking the time to read this. I would like to know the "best practices" for unplugging my computer permanently to the internet and other updates. I thought I would do a clean install of Windows XP, install my Microsoft Works again and nothing else. I would like to effectively transforming my computer into a word processor. He continues more and more slow. I get blue screen errors, once again. I received excellent Microsoft Support when it happened before, but since my computer is around 13 years, I think it is not worth the headache to try to remedy. I ran the Windows 7 Upgrade Advisor, and my computer would not be able to upgrade. Please, can someone tell me how to make it only a word processor without updates or internet connection? (I already have a new computer with Microsoft Windows 7 Home Premium, it's the computer that I use. The old computer is just sitting there and once a week or so I updates.) I appreciate your time, thank you!

  • Just improved m tips on best practices for sharing files on a Server 2008 std.

    The field contains about 15 machines with two domain controllers, one's data is the app files / print etc...  I just upgraded from 2003 to 2008 and want to get advice on best practices for the establishment of a group of file sharing. Basically I want each user to have their their own records, but also a staff; folder. Since I am usually accustomed to using windows Explorer, I would like to know if these actions can be done in the best conditions. Also I noticed on 2008 there is a feature of contacts. How can it be used? I would like to message or send an email to users their file locations. Also, I want to implement an admin at a lower level to handle the actions without making them far in on the server, not sure.

    I read a certain bbut I don't like test direct more because it can cause problems. So basically a way short and neat to manage shares using the MMC, as well as the way that I approach their mail from the server of their actions. Maybe what kind of access cintrol or permissions are suitable also for documents. Also how can I have them use office templates without changing the format of the model.

  • Best practices for the integration of the Master Data Management (MDM)

    I work on the integration of MDM with Eloqua and are looking for the best approach to sync data lead/Contact changes of Eloqua in our internal MDM Hub (output only). Ideally, we would like that integration practically in real time but my findings to date suggest that there is no option. Any integration will result in a kind of calendar.

    Here are the options that we had:

    1. "Exotic" CRM integration: using internal events to capture and queue in the queue changes internal (QIP) and allows access to the queue from outside Eloqua SOAP/REST API
    2. Data export: set up a Data Export that is "expected" to run on request and exteernally annex survey via the API SOAP/REST/in bulk
    3. API in bulk: changes in voting that has happened since the previous survey through the API in bulk from Eloqua outside (not sure how this is different from the previous option)

    Two other options which may not work at all and who are potentially antimodel:

    • Cloud connector: create a campaign questioning changes to schedule and configure a connector of cloud (if possible at all) to notify MDM endpoint to query contact/lead "record" of Eloqua.
    • "Native" integration CRM (crazy): fake of a native CRM endpoint (for example, Salesforce) and use internal events and external calls to Eloqua push data into our MDM

    Issues related to the:

    1. What is the best practice for this integration?
    2. Give us an option that would give us the close integration in real-time (technically asynchronous but always / event-based reminder)? (something like the outgoing in Salesforce e-mail)
    3. What limits should consider these options? (for example API daily call, size response SOAP/REST)

    If you can, I would try to talk to Informatica...

    To imitate the integrations of native type, you use the QIP and control what activities it validated by internal events as you would with a native integration.

    You will also use the cloud api connector to allow you to set up an integration CRM (or MDM) program.

    You have fields of identification is added objects contact and account in Eloqua for their respective IDs in the MDM system and keep track of the last update of MDM with a date field.

    A task scheduled outside of Eloqua would go to a certain interval and extract the QAP changes send to MDM and pull the contacts waiting to be sent in place of the cloud connector.

    It isn't really much of anything as outgoing unfortunately use Messaging.  You can send form data shall immediately submit data to Server (it would be a bit like from collections of rule of integration running of the steps in processing of forms).

    See you soon,.

  • Best practices for network configuration of vSphere with two subnets?

    Well, then I'll set up 3 ESXi hosts connected to storage shared with two different subnets. I configured the iSCSI initiator and the iSCSI with his own default gateway - 192.168.1.1 - targets through a Cisco router and did the same with the hosts configured with its own default gateway - 192.168.2.2. I don't know if I should have a router in the middle to route traffic between two subnets since I use iSCSI ports linking and grouping of NETWORK cards. If I shouldn't use a physical router, how do I route the traffic between different subnets and use iSCSI ports binding at the same time. What are the best practices for the implementation of a network with two subnets vSphere (ESX host network: iSCSI network)? Thank you in advance.

    Install the most common iSCSI would be traffic between hosts and

    the storage is not being routed, because a router it could reduce performance.

    If you have VLAN 10(192.168.1.0/24) iSCSI, VLAN 20 (192.168.2.0/24) ESX

    MGMT and VLAN 30 (192.168.3.0/24) comments VMs and VLAN 40 (192.168.4.0/24)

    vMotion a deployment scenario might be something like:

    NIC1 - vSwitch 0 - active VMK (192.168.1.10) MGMT, vMotion VMK (192.168.4.10)

    standby

    NIC2 - vSwitch 1 - current (VLAN30) guest virtual machine port group

    NIC3 - vSwitch 2 - active VMK1 (192.168.1.10) iSCSI

    NIC4 - vSwitch 2 - active VMK2 (192.168.1.11) iSCSI

    NIC5 - vSwitch 1 - current (VLAN30) guest virtual machine port group

    NIC6 - vSwitch 0 - MGMT VMK (192.168.2.10) standby, vMotion

    VMK (192.168.4.10) active

    You would place you on VLAN 10 storage with an IP address of something like target

    192.168.1.8 and iSCSI traffic would remain on this VLAN. The default value

    gateway configured in ESXi would be the router the VLAN 20 with an ip address of

    something like 192.168.2.1. I hope that scenario help set some options.

  • Best practices for storing the Logs of the system for all newly improved ESXi hosts?

    Hi people,

    What are the options and best practices for the Logs of the system for all newly improved 5.1u1 ESXi hosts?

    Do I need to have the Syslog server or it can be safely ignored?

    Thank you

    Evening,

    Syslog is preferred, but VMware has provided a collector of syslog on the vcenter installation disc can be installed on any windows host or your vcenter. I can't count the number of times where I had guests CMTF or newspapers lost... Fortunately for the syslog which collects up to the accident.  It is not necessary, but it's really a good idea without any real cost since you can use your vcenter host.

  • Best practices for the application of sharpness in your workflow

    Recently I tried to get a better understanding of some of the best practices for sharpening in a workflow. I guess that I didn't know, but there are several places to sharpen. Who are the best? They are additive?

    My typical workflow involves capture an image with a professional DSLR in RAW or JPEG or import into Lightroom and export to a JPEG file for the screen or printing of two lab and local. 

    There are three places in this workflow to add sharpening. In the DSLR manually into Lightroom and when exporting a JPEG file or print directly from Lightroom

    It is my understanding that sharpening is added to RAW images even if you add sharpening in your DSLR. However sharpening will be added to the JPEG from the camera. 

    Back to my question, it is preferable to manually the sharpness in the SLR in Lightroom or wait until you export or output of your printer or final JPEG file. And additive effects? If I add sharpening to the three places I am probably more sharpening?

    You have to treat them differently both formats. Data BULLIES never have any sharpening applied by the camera, only JPEG files. Sharpening is often considered to be a workflow where there are three steps (see here for a seminal paper on this idea).

    I. a step sharpening of capture which compensates for the loss of sharp in detail due to the Bayer matrix and the filter anti-repliement and sometimes the lens or diffraction.

    II. A creative sharpening step where some details in the image are 'highlighted' sharpness (do you eyelashes on a model's face), and

    III. output sharpening, where you fix the loss of sharpness due to the scale/resampling for the properties of the average output (as blur because of an impression how process works or blurry because of the way that a screen LCD sets out its pixels).

    These three are implemented in Lightroom. I. and II. are essential, and basically must always be performed. II. until your creative minds. I. is the sharpening that see you in the Panel to develop. You need zoom at 1:1 and optimize the settings. The default settings are OK but quite conservative. Usually you can increase the value of the mask a little so that you're not sharpen noise and play with the other three sliders. Jeff Schewe gives an overview of a strategy simple to find the optimal settings here. It is for the cab, but the principle remains the same. Most of the photos will benefit from optimization a bit. Don't go overboard, but just OK for smoothness to 1:1.

    Stage II as I have said, is not essential, but it can be done using the local adjustment brush, or you can go to Photoshop for this. Stage III, however, is very essential. This is done in the export, the print panel Panel or the web. You can't really get a glimpse of these things (especially the sharpening printing-oriented) and it will take a little experimentation to see what you like.

    For jpeg, sharpening is done already in the camera. You could add a small extra capture sharpening in some cases, or simply lowering the sharpening in camera and then have more control in the post, but generally, it is best to leave it alone. Stage II and III, however, are still necessary.

  • AF best practices for video

    I'm using an EOS 7 d for 1080 p HD video shooting. New to SLR camera and digital video. I have watched several tutorials but do not yet have a good understanding of what the best practices for the development.

    If I put the camera in AI Servo it will auto focus if the subject is moving away or toward me with depress me back AF-ON or the shutter button? Or should I press one of these buttons to make the camera continues to focus?

    You know tutorials or video lessons that cross using update with the video?

    Thanks in advance!

    I don't know any tutorials, but more serious videographers say it is best to use only the manual focus.

    Trial and error is a good teacher, when it comes to video DSLR. You'll quickly learn that video Auto Focus is really bad with the 7 d and most of the people do not use it all together.

    The method that works for me is to use AF before the filming of the video and then adjust manually if you want to you to shoot the video. With the help of f/8 or f/11 to keep everything in short without having to keep the setting.

    More recent Canon DSLR's like the T4i, T5i, 70 d and SL1 have a "hybrid AF" that does a much better job of AF during video, but it is not yet as good as a camcorder

    If the data inserted by the user are ok, a new record in my custom db table Users will be created.

    I would be happy if you could give me some examples.

    Assuming you want the validation on the value of the field to any screen data can be entered in (and possibly web services that rely on the same BC ADF) then put the validation on the definition of the attribute in the EO.

    If you want to add a little more friendliness and eliminate some of the network traffic to the server, you can also implement the validation client in your page - for example by using the regular expression validator.
