The design of potential - thoughts?

Looking at a updating of the material here and entertaining vSAN as part of the solution.

Proposed solution:

Two sites. Will use SRM with vSphere replication and vSAN.

Consolidation to three ESXi hosts in the primary and secondary sites with Essentials more license kit. With the help of vSAN. The material is Dell R720xd servers filled with possible drive with disc magnets 12 24 bays to allow expansion. Either two or four of the 12 other bays on each host will fill with SSDs. Solution will build HA.

Issues related to the:

Can you jump on a 10GbE switch and interconnect between hosts 10GbE adapters? X 520 or x devices using Intel 540, would double on them and connect the hosts to another directly instead of buy two switches 8-port 10 GbE by the environment for redundancy.

Whereas 12 x 600 internal GB 10K 2.5 "drives per host with SSDS additional 2-4 for the cache. What my useful capacity provides 1 failure to tolerate by VM?

Am I missing any consideration here with regard to interoperability, etc.?

Thank you!

Cheap is always subjective depending on what is the budget and what you are to compare.   The set of features is compelling for its price range.

I wouldn't imagine you can ignore the switch with a host 3 VMware Virtual SAN environment, but I've seen other systems that work in a configuration of 2 host.

SynchroNet did a performance white paper switch VSAN - http://www.synchronet.com/blog/vsan-switch-performance-whitepaper/

The results show that you could get good performance with relatively modest network facilities.

VSAN requires SSDs, they are not optional.  Each disk group must have a minimum of 1 SSD and 1 HDD (up to 7 hard drives by group).  SSD is used to read the cache and writing to the buffer.

I would not use all records that were not on the VSAN from VMware HCL list. You want something with an endurance of write.  The recommendations are of life 5 years with 10 operations of writing per cell per day.

The discs of the series intel s3700 are fine for this.

I'm happy to help where I can.  If you really want to get a jump on things I recommend the book of Cormac and Duncan essential Virtual SAN (VSAN): Guide to VMware Virtual SAN administrator. There is also a hands on lab, you can play with over at VMware - Labs

  • After applying a template to a page, the design mode is empty - I can change only in code view.

    When I apply a template to a page, it's fine. I can see the elements of the page in design view and code view. I can edit the page and upload it and everything is fine. However, when I save the page under a new name or close the page and then reopen the design mode is empty, the code mode is normal. I would like to be able to see the page in design view and cannot. I don't know what to do. I hope someone has an idea for me. Thank you.

    I use PS CS5 and pages are ASP.

    I was opening a page, then application of a model (dwt) him - then ' record as. I now create a page that you mentioned, and that's fine. I saved and closed and then reopened and things are visible in Design view. It will take a while to redo this page and others - but it seems that it will work.

  • Help required to choose the designer of Livesycle or any other

    Hi

    I am working on a project of web based Government developed using J2EE. Forums are pretty useful. I need help from your team choosing products adobe for our requirement.

    We have a requirement in which we want to give a form offline to users of the client. (Unlimited)

    Then, we wanted to give the provision the user to download the form in the customer Web site.

    Finally retrieve us the data from the form and store them in DB.

    For the prescription above I thought to use Adobe LiveCycle designer. Once the form is designed and sent to end-users,

    1. how the user can save the form.

    2. it can save the form to PDF / XML or in any other format that it can download from the site.

    3 is there a provision to get the fields in pdf form by calling request.getParameter () in HTML forms is how to read form in JAVA is to say like.

    (Including images)

    Once I get the fields of the form in Java, I can store in DB.

    Please help in this regard and to offer the right product for our needs.

    Once this is done, then assess us and plan to purchase

    Thank you

    Designer would create a PDF file that the user could load in their Reader or Acrobat. The PDF would be either the data input by the user (XML) or PDF to your web server for the treatment of post like an HTML form). The ability to present outside of the browser and the ability to allow users to partially drop the form and save work in progress and users use drive then you would require LiveCycle Reader Extensions enable the features of the player. Once you decide what you send, then you would enter the presentation into your program Java the same way you would for a HTML presentation.

    I suggest you contact your Adobe representative to discuss more in detail.

  • Lights of fireworks or Dreamweaver to start the design process?

    Please tell us which is the best application use to start the design process a site, from the point of view of a print designer code-illiterate - I assumed it would be Dreamweaver but read somewhere recently that I should start in Fireworks (which I always thought was more for the creation of graphical web content optimized).

    As a print designer, I use InDesign CS4 (with Photoshop and Illustrator) and would like the tool more logical and intuitive to use to start the work of designing a site with advice.

    Once the design is approved I will have someone who knows what they're doing with HTML, CSS and PHP etc to check everywhere and make the delicate bits.

    Any help in pointing me in the right direction would be appreciated.

    Thank you.

    PS - my apologies if this is wrong forum label, but I posted this question yesterday on the Web Design Forum, but then thought that this may be a more appropriate forum to publish.

    If you are a designer to create a new design, Fireworks is a great place to start. (I can't imagine trying to design in Dreamweaver, frankly). If you are familiar with Photoshop and Illustrator, you might start with one of these applications, too, but Fireworks has been built to work.

    However, Fireworks is not a coding tool. Like Photoshop, it has the ability to export HTML, but the feature is designed to create models, not live sites. After you have your site designed in Fireworks, you or someone else can use Dreamweaver for (re) - produce the design in the code.

    You can use Fireworks to statements your vertical grids, placing graphics header and navigation, place-holding text value (remember that HTML text can be resized by our users, places for blocks of text must therefore be able to resize). And Yes, once you have your design, use Fireworks to slice that design and export the graphics optimized for your encoder to use.

  • Philosophical question about the design of the table

    I'm new in the world of RDBMS. I read a lot but have little practical experience. I'm upgrading of old applications that I know well. I'm interested in advice/opinions on a number of issues, from it.

    My application periodically (at the discretion of the user, so can be daily, weekly or monthly) should take a snapshot of some data. This snapshot is then used for various activities, such as a control point of reconciliation with external clients - so it must be 'frozen' rather than be derived at a later date. But if the snapshot proved to be a mistake, I can possibly be rerun (crushed) - requiring all lines to delete everything first.

    Data must be accessible in different ways, everything would need the date of snapshot to be part of the index or a group of clauses.

    Snapshots can be copied or replicated to other servers for purposes to relieve the burden of filing database. Old clichés may be archived, ignored backups of routine, deleted and so on.

    Is there a case for the inclusion of the date of snapshot as part of the name of the table? It would simplify the index structures, reduce the size of the individual table, perhaps to improve the competition (for users who access an old cliché while another is being created), facilitate separate archiving and much easier to drop and create table to remove all the lines before a replay. Of course, it reduces the size of the table that could potentially become very large.

    However, the previous snapshot is used as a starting point for the following, or a subsequent repeat) you need to be able to quickly determine who is the nearest date start - easy if they are all in 1 table, can be more load trying to determine is whether a specific table at the time to a given date.

    I look forward to some expert advice. :)

    No--not from a point of view of the data modeling. The snapshot date is an attribute. Attributes are not incorporated in the name of the entity being modeled.

    However, you can decide to implement the instant entity tabular instant daily - but the attribute date (column) will always be an attribute. In other words, you must not remove the attribute date as a table column as the table name now.

    This decision (implemented as a multi table entity) have meaning when not having is not a better way to manage the physical aspects of the table. Partitioning for example would be a much better option to use - a single partitioned table, containing multiple partitions, where a partition physically contains data for a specific instant day (including the index).

    Basically, there is a very clear line between the logical data modeling and the material realization of this model. Oracle provides a bunch of features that you can use on the side of the material realization. As index organized tables. Table of clusters, partitioning and so on. But how you implement the physical model does not dictate the design of the logic model.

    However, the previous snapshot is used as a starting point for the following, or a subsequent repeat) you need to be able to quickly determine who is the nearest date start - easy if they are all in 1 table, can be more load trying to determine is whether a specific table at the time to a given date.

    I would use a management entity - that describes the metadata for a snapshot. As when it was created, the filter criteria used, the time it took (still useful for performance and troubleshooting purposes), be it an an active/valid capture instant or not - or any other attributes necessarily to manage this logical snapshot as a set of data.

    The biggest problem with a physical model that uses separate physical tables for the same entity, it is appropriate to use table name must be determined at run time. This means dynamic SQL. Dynamic SQL means an increase in complexity, open any SQL injection holes, having to deal with errors which would not intervene with static SQL, etc.

    If this approach to your data model's physical implementation needs a review carefully to ensure that it works as efficiently and effectively as required.

  • I use the full version of DASYLab 8.0, how to add PID module in the design of the façade (window layout)? while I can vary the p, i, d values in the window layout

    I use the full version of DASYLab 8.0, how to add PID module in the design of the façade (window layout)? while I can vary the p, i, d values in the window layout

    To do that you will need to change the varibles PID values and then use the sliders to add numbers to a latch for variables that point.

    This is how I think it works in Version 8.

    In all cases, you should move on to 12 more stable summer.

    In addition, unless that is a very slow process, I generally do not like closed loop PID with DASYLab due to the fact that computers is not reliable with timing.

  • Should I use the design of producer/consumer model (Instead of Globals)?

    Hello everyone.

    I have a request including several loops in it. A loop reading data series and he analyses for use in the other loops, another loop acquires via DAQmx data and performs calculations on it for use in other loops, the other formats the data from two loops and poster and one last test data. I was wondering if this is a good candidate for the design of producer/consumer model.

    For now, I use global variables to send data from the series and DAQmx loops to other loops. I use motors of the action for the different parts of the program that should be used everywhere, as the serial port. The test loop needs than the most recent data to run his test.

    Thanks for your suggestions!

    The short answer is Yes. If nothing else using queues to pass data will allow your various loops inactive if no data is present. By using globals your curls must continuously survey to see if the data has changed. You always are beter off if you can make your request, driven by events rather than to use the polling stations.

  • High availability of components in the design of vWorkspace tips

    Hi all

    Would ask you some advice regarding the design of vWorkspace components highly available. Suppose that vWorkspace components will be deployed in vSphere or hypervisors managed SCVMM hence HA is in place, if the failure of a host. In this situation, if we still need components redundant (n + 1 VMS) vWorkspace?

    On the other note, I understand that we can add a couple of broker for vWorkspace in vWorkspace Management Console connections and based on KB 99163 it would just work. I'm not sure how the traffic would be when an application is web access? As in, I guess that the connection broker news would be 'defined' at the request of the web call to the broker for connections. Or this is done automatically? Access Web would choose randomly from the broker for connections to go?

    Thanks for any advice in advance

    Kind regards

    Cyril

    Hi Cyril,.

    Big questions. As with any IT architecture in layers, you must plan HA and redundancy at all points of failure required by your environment or level of Service (SLA) agreements. For vWorkspace, the center of his universe is SQL and you must plan accordingly the failure and recovery. In some environments, full backup can meet the requirement of HA. In others, full SQL Cluster, Mirroring, replication, or Always-On configurations may be required. With our broker, we recommend N + 1 deployment in most scenarios HA. When you move peripheral components or enabling, you must evaluate each component and needs its impact of failure as well as its valuation to determine the appropriate AP.

    Load balancing between several brokers is done automatically by logic in the client connectors. In the case of Web access, when you configure the site Web Access in the Management Console, it includes broker list in the Web access configuration xml file. As client connectors, Web Access includes balancing logic that distributes the client load on brokers available automatically.

    If you have any questions about specific components and requirements of HA or architecture, please add them in the discussions.

  • Why the touch screen is good for the design of the window?

    Touchscreen seems to be an approach of incorrect interface on the design window, I need a lot of lotion to keep my skin healthy, been to designers?

    Thank you

    Well, a touch screen is completely optional with Windows 8. While it is designed for you to use a touchscreen, there is nothing in the design that prevents you from using a mouse and a keyboard. In fact, IMO it works a little better with m/k with the touch screen.

    It's just an additional way to interact with your computer - touch screen is not intended to replace other ways.
