Build HA project - looking for feedback

Hello. I need to test the response of our software to a host failover high availability in a vSphere environment. We do not currently have the equipment or the necessary licenses to test this workflow, so I'm looking for an overview acceptance or rejection of the next generation. Any thoughts are appreciated.

Our software:

We have a two server configuration (A and B) with each server that holds a mirrored to a proprietary database stored on a raw partition. These servers run on Red Hat Enterprise Linux 5/6. Customers and various demons are balanced on these servers.

If one server dies, the survivor of the system reconfigures to balance the load of the customer. It works very well in stand-alone virtual environments, but we have to see what happens if A is on VMHost 1, B is on 2 VMHost, one of host channels and the prompt automatically skip to the other host.

Construction project:

  • One license for VMware vSphere Essentials Plus Kit.
    • The kit more essentials offers vSphere Storage Appliance. This device would be used for a store of data mirrored on two hosts.
  • Two Dell PowerEdge T320 towers, each of which contains:
    • 64 GB OF RAM
    • 1 processor (6 core Xeon E5-2430)
    • 3 TB RAID6 with PERC H710p RAID controller

Guests:

  • Host 1 hosts our server A and several other independent auxiliaries/utility servers.
  • Host 2 hosts our server B and several other independent auxiliaries/utility servers.

Goals:

  • Determine how our software reacts in general in a failover scenario, where 1 host dies and comments automatically reassigns on host 2.
  • Determine if our local databases are mirrored if no disconnection is detected (30-60 seconds of non-contact).

Issues related to the:

  • A single VMware vSphere Essentials Plus Kit offer all the necessary licenses and the appropriations allocated for this test?
  • The proposed material is acceptable?

Ask you questions about the specifications of equipment for the production or test?

You can also make the HA using VMware workstation tests, and some nested ESXi hosts (all in eval mode). I have this setup at home using VMware workstation 8, 5 x servers (60 days trial license) virtual ESXi and vCenter Server apparatus or else a Win2k8 server with vCenter installed (my preference). The entire Setup is running on standard HP media computer with 16 GB of RAM and I also use NFS on my NAS for shared storage. Maybe the server files open or something else might work for you?

    I'm actually trying to figure out how I can find the email for my eprinting between my HP Officejet Pro 8600 and my Android II. I downloaded the eprint through market software on my android and I checked everything on the menu on my printer for the e-mail, and I can't seem to find an email address. I'm confused. I saw your posts and I'm not finding what I need. Can you help me? Thank you!

    Hi rlwrites4u,

    Try to find the menu "Web Services" or "Menu of the Web". Once you find this menu if you have already activated it before it will ask you to activate the web services, then it will print a page "info" with the steps to set up the email address of your printer. If you don't get invited to enable web services once in the "web" menu, then look for the option "Print a Page of Info". The page may take a few minutes before it prints but after that just follow the steps that it prints.

    Although I work for HP, my messages and responses are my own opinion and not of HP.

  • ~ construction of $3,000 for PrPro (and PS/LR edition) - looking for feedback

    Hi all! First time poster here.

    It's finally time I put together a new video editing PC. my current is from early 2012, and it's definitely showing its age (cost about $1200 at the time). Here is the parts that I chose after extensive research, but I was expecting a feedback (or hopefully, confirmation) when it comes to a balanced system. I'll mainly be video from a C100 and 5 3 edition, so no 4 K (yet), but I want something that will last me a few years of publishing. My current level of use floats somewhere between hobby and side business, but I hope to edit more as time passes.

    PCPartPicker list of the part: http://pcpartpicker.com/p/tdJrhM

    Processor: Intel Core i7 - 5820 K 3.3 GHz 6 - Core Processor

    Project/media player will only be used at home for projects that are currently active. everything will be saved and archived on a device NAS Synology DS415 + connected to my network servant gigabit. I'm going to be creating that at the same time that this build; due to financial constraints, I will start with either one alone 4 TB WD drive red or two of them during a RAID in mirror, but hope to add more soon!

    Thanks for the comments and especially by harm Millaard whose words of wisdom of storage I hope have interpreted correctly.

    CPU cooler: take a look at the Noctua NH - D14, D15 - NH or Phanteks-PH-TC14PE

    thermal paste: switch to something that is not conductive and does not have 200 hours to turn on completely.

    There are a lot of compounds of coolermaster, artic and tuniq to name a few.

    motherboard: asus or gigabyte, make sure it has the features you need.

    storage: move to the PRO samsung series 850 or intel 730 480 GB. If planning on the Raid in the future to go with the intel 730 480 Go.

    GPU: pass the 980 to the 970 gtx gtx. the price of the performance does not justify the gtx 980.

    case: move to something with 140 mm fan options, like Fractal Design refine R5.

    power supply: If do an overlock considers going to 1000 watts or more.

    OS: windows 8 looks like a joke and was made for tablets or noobs in microsofts lyrics, it is better under the hood and its possible to use programs such as the classic interface or debut8 to make it look like win7.

  • Looking for a CMake build

    Hello

    I'm looking for a generation of CMake project sigar.
    I found this thread http://communities.VMware.com/thread/347442 is a former. Unfortunately this version does not work for me (linux_sigar.c:32:43: error: asm/page.h: no such file or directory).

    I was wondering if CMake builds were always held by someone. It would be easier for me to integrate the sigar like this library.

  • Is it possible to build a project with Labview 2010 on a Windows XP system, which is useful for a system with windows 7 on it?

    Hello

    I intend to use Labview 2010 in no time.

    But before I go to use it I have a few questions.

    1. I know that it is possible to run Labview 2010 in an XP environment. But is it also possible, when running Labview 2010 on an XP system, to build a project for a version that is useful in a Windows 7 environment?
    2. Or should I run Labview 2010, when I want to build a project that is useful on a Windows 7 system, on a system with Windows 7?

    Please give me some information.

    I hope to hear from you soon.

    Kind regards

  • Looking for ideas of navigation... clarify the terminology used in the project

    Hi people... looking for some ideas for my Captivate 5 projects navigation.

    I have a project which is executed automatically, which means it does not require the participant to click on previous/next buttons to proceed with the project. I display the standard navigation in skin buttons, however. I use also the voice-over to tell the whole project. On several slides I use specific terms or concepts that the participant may want to get more information on the... which I am more than willing to provide.

    What I would like to know many of you seasoned users of Captivate is how you would allow participants to get more information about a specific term / concept presented as underlined text in slide balls without interrupting the flow of the entire project. I thought to use click boxes that send them to another page (branching) and then provide them with a button that we continue them with the project from there. I also considered to use overview legends, too, but if they don't find the bearing before the slide advances, they miss the opportunity to ride on this point. I'm not a big fan of prompting the participant about the existence of the bearings,... I just use underlined text indicating a "hyperlink" so-to-speak.

    Anyone have some creative ways to this address?

    Hello

    Now, you will know that I prefer screenshots: you can easily duplicate a total script (see yellow highlighted button), perhaps it is better to change the default name of the script in double. ATTENTION: each object has the correct ID, in this case, it's the text caption (I've marked it ExplanationTC), so you will have to change.

    It is not possible (yet) for export/import of advanced actions

    In my last blog I tried a workaround using a model solution, maybe you saw?

    Please, this post is still profoundly marked also unanswered?

    I have Production Premium with Encore CS6.  I created my first HD project, tested and received no error but when I went to 'Building' my project still on a BluRay disc, I got the error message "ERROR CORE 03".  What should I do to get this project on a BluRay disc?

    In response to both Richard & Stan.  I received the error message ""device error", Code '3' notes Create Sequence of STC: cannot write file M25.»  Or something very similar to this, but I think it was exactly that.  It was my first HD project but used several times to make projects sustainable development without problems that were not of my own creation.  So it was a shock and cost me money and the failure to meet a deadline.  What I did: on-screen 'Build '.

    Format: Blu - ray,

    Output: Blu - ray Image,

    Source: Currrent project,

    Destination: I Browse... d a location appropriate.  He managed a Blu - ray image.

    Using reminder once again, step 2 - on-screen 'Build '.

    Released: Blu - ray Disc,

    Source: Disk Image,

    Destination: my disc drive that holds a blank Blu - ray disc.  He managed a Blu - ray disc.

    Then I found a job step 2 autour for the problem.  My question is this: I pay $70.00 / month ca to the people Adobe cloud to keep their software up to date and work as advertised.  I do not think I should spend a few hours and lose money looking for a problem created Adobe not yet keeping cs6, updated and works as promised.  I submit my first bug report.  My suspicion is that adobe considers that Blu - ray is out of style, and they do not care to correct this bug in still cs6.

    I'd love to know the thoughts of others on this.

  • Beginner looking for best practices to implement my first ESXi server.

    Hello, tomorrow I will start my first company ESXi.  I ordered a HP Proliant ML350 with e200i Raid 5 controller.  I bought 4 1 TB Sata disks and plan to put them all in Raid 5 for 3 TB of data storage.  I currently have a file Win2k3 server which has approximately1.5TB of files on several physical disks spread now.  My question is how these data should be moved to the new server?  Should I build a new machine virtual server OS 2003 or 2008 and then allocate all 1.5 + TB I this one VM?  How the data will look like ESXi?  Have I not separated or just 1 virtual players a large?  Or is there a better solution?  What should I do when I start running out of space and should allocate more space to the descent to a certain VM?  I apologize if this is a stupid question, but I'm just a little confused and trying to get all oriented upward when I started on this project in the future.

    Thank you very much!

    You can build on Windows Server as shown above, and then create a virtual disk to host your data. You can then use something like copy robo to synchronize the data from your original data source, you could kick off for a weekend and then use robocopy to just capture changes before making your actual failover. Just be aware of the limits that the other person has remarked with the 2 TB. You can select the block maximum size when you create your VMFS datastore for your data drive, otherwise the VMDK max, you create will be a little less then you are looking for.

  • I'm looking for a theme of book with the right combination of text and photo layout.

    I'm doing a book project I have Photos for Mac. I would like to include text, but then discovered that some themes have not; the I took has only pages full of text. Another is, but offered just 3 photos on each page, in strange layouts.

    The main problem is that when I pick I see nothing other than the cover. I have to build the project to see what I get. Is there another way to see them, or choose one based on preferences?

    And when did things become so shitty? I have created a book in iPhoto, and it was really easy.

    Mostly by trial and error.  What I did is create a test with a few photos with the first theme of book available.  I then he reproduced several times and changed the theme to one of the others.  I now have a test for each of the themes book.

    When I want to create a new book with a particular theme I duplicate the test book, rename it and use it.

    There is something generally wishing to each of the book themes: features and Photo Book Formats.  If descriptions are insufficient, so trial and error described above will be necessary.
