NetApp Best Practice and independent labels
Hi, Best practices for VMware NetApp recommends, transitional and temporary data such as comments
pagefile operating system, temporary files and swap files, must be moved to another disk virtual one
different data store as snapshots of this type of data can consume a large amount of storage in a very short time
high time due to the rate of change (that is, to create a data store dedicated to transitional and temporary for all VMS data without other types of data or VMDK residing on it).
NetApp recommends also configure the VMDK residing in these stores data as "Independent persistent" disks in vCenter. Once configured, the transitional and temporary data VMDK will be excluded from the VMware vCenter snapshot and copy snapshot of NetApp initiated by SnapManager for Virtual Infrastructure.
I would like to understand the impact of this best practice - can anyone advise on the following:
- If the above is implemented:
- Snapshots will work via vcenter?
- Snapshots will work via the Netapp Snapmanager tool?
- The snapsot includes all of VM disks? If this is not the case, what is the consequence of not having the whole picture of the VM?
- The snapshot of vcenter can restore ok?
- Netapp snapshot can restore ok?
- What impact the foregoing has on the process of return if using a backup product that relies on snapshot technology?
Thank you
Hi Joe
These recommendations is purely to save storage space when the replication or backup.
For example, you can move your *.vswap (VM swap file) file to a different data store. NetBackup can do instant IVMS of the warehouses of data and with this configuration, you can exclude this particular data store
This is also true if you create a data store dedicated for OS Swap files, mark independent so that vCenter not relieve these VMDK.
I did a project with NetApp on boxes of SAP production
We moved all the files in *.vswap to warehouses of data created and dedicated RDM for the OS Swap locations
We actually used the SnapDrive one NetApp technology to suspend the DB SQL on the ROW before the ROW is broken, but I won't go into too much detail
To answer your questions (see the comments in the quote)

-OS Swap VMDK of location must be re-created in the case of restoration. WIndows will be
always Prime if the Swap disk is missing, and you specify the new location of swap.
- What impact the foregoing has on the process of return if using a backup product that relies on snapshot technology? -These backup products use vCenter snapshots and because the vCenter snapshots works 100% it shouldn't be a problem.

I can work on after effects being coded by best practices and Media Encoder file
I just found out that after effects files can be returned outside the program using the media encoder. I had been made in after effects of .mov, then open the file in photoshop to render the .mov to a mp4. Not the process faster, but it worked. If I use media encoder to make my legacy model would still be able to work in AfterEffects and edit and save the file rendered in media encoding, or it is locked? I hear also the media encoder is slower than the after effects encoder. What are the best practices for a comp sequelae which makes a mp4 (h264)? Thank you...
Depending on what you do the SOUL can be slower than using index rendering, but that's the only thing that you must use to make H.264 files.
When you send a model to the SOUL a virtual copy of this composition that is the source for this rendering. You can continue to work on the same computer and additional changes but if you want these changes appears you will need to send this model to the SOUL again after making the changes.
Almost without exception, I'm working on plans not and certainly never movies sequences in After Effects. My average computer is probably seven seconds, my average film is probably 30 minutes so I use AE to work on plans for effects which cannot be treated in my NLE. I almost always send a model to the SOUL to render a h.264 or a suitable production master, or both, and then I continue working in AE because I can't afford to wait for a rendering time. On almost all of it is the more efficient workflow.

Upgrading ESX 3.0.2 for 3.5 - best practices and tips
Hello
I am currently managing a virtual environment running on ESX 3.0.2 and VC 2.0.2. I intend to upgrade this year to ESX 3.5 and VC 2.5. Anyone know where I can find information on best practices to upgrade and / or a document of instructions that will take me through the process? I had a glance on the VMWare Web site but cannot find anything.
See you soon

I have attached a document with this information.
First of all you must upgrade the VC and the database, then you must upgrade from ESX.

R610 Perc 6 / i Can I have matrix Raid and independent labels?
My R610 with a Perc 6 / I can take 6 physical disks. I want to create a raid 1 with the first two discs, then install 3 drive more that BONES can see and use in a storage space. However, I can't figure out how.
I have my setting up a raid and windows installed and I have the other 3 drives inserted, but Windows does not see them. Maybe that's not possible, but I wanted to ask if anyone else had any ideas on how to make this work.
Thank you.
PERC 6 is not compatible no RAID, so if you want to use these disks separately, you must configure each as a single drive RAID 0.

Web Viewer: Best practices and Limitations
The opportunity to share our publication online via a web viewer is an asset to have. However, I noticed some blockages in two folios, we have made available online: videos suddenly stop playing; slow scrolling pages are not completely accessible to see; interactivity does not work in different browsers. I wonder if there is any documentation or advice to ensure a smoother experience across all display options.
Hello
Thanks for the additional details. We look at the issues you reported and have a few comments.
Here are a few quick notes for each of the elements.
-Video suddenly stop playing.
We had a new web viewer updated today, and this seems to have solved the problem with the video stopping on this article.
In this article, there is a play button placed inside the OSM. ASM has been put to play as a slide show and the loop. It was originally an interaction with the video that caused it close. We have made some changes to the way video MSOs interact in this latest version, and that avoids this problem.
Yet, in this case, apparently not necessary to use the DSO or even a button. For videos full screen like this, you can simply create the video overlay on the image of the button. With videos full screen, the area of overlay that you define behaves like a button "play" without you having to add explicitly one.
-Scroll effect slow pages are not completely accessible for display
We have also looked at this article and are able to reproduce the problem. As we develop a solution, we will work to get to a workaround to help you avoid this problem. We'll post here when we have some suggestions for you.
-Interactivity does not work properly in different browsers
We have experienced some problems with certain types of content in Internet Explorer. We are working on some improvements to help reduce these.
I will address the two items that you referenced separately.
-Multi-state objects does not properly
There are some limitations with IE when it comes to the way it handles the interaction events. In this case, the layout of the content can be slightly adjusted to avoid this problem. I noticed that the positioning of several ESM is a little bit off.
For example, the "VISUALS4" MSO is supposed to appear on the fourth page (index of the #3 page). However, if you look carefully at the InDesign file, you will see at the top of the OSM superimposed on the previous page of two pixels. As layering begins on the previous page, this is how it is rendered. Most modern browsers can handle this correctly, but it affects the stacking order in a way that causes a problem with IE.
If you move all WHO the problem a few pixels to make sure that the upper part of the WHO is aligned with the top of the page, it should work properly in Internet Explorer.
-Overlay of the play button has somehow to only changed the blue outline
In reviewing the file folio for the article, it shows that the two States for the MSO play button use the same image.
I don't know what the behavior planned for this MSO. It is configured as a slide-show mode that loops between the two States, once it is clicked. Because the OSM will be covered by the video full screen, which is the desired effect? Please explain what you want to achieve and we can provide suggestions.
-No support for overlays
On some browsers, including some versions of Internet Explorer, we support all interactive overlays. The screenshot you posted seems to be an overlay of imageSequence. This special overlay is not supported on some versions of Internet Explorer.
Please let us know if you have any other questions or encounter other problems. We will do our utmost to help.

Best practices and advice to help you need to create an animation
Hello
I produce my first project in AE and came across this example which is similar to what I have need to be implemented in the project.
(see 8 seconds in the video of imagespot)
My scenario is that I need to portray a network of nodes that are all related (and possibly growing in number, network links and nodes flourishing points of spawn of other nodes describing the network is an infinite extensible entity).
Could anyone suggest how I would create this, direct me to tutorials, or let me know what is the term for this kind of kinetic movement related?
The important thing, I guess, is how to manage the efficient workflow. There must be a better way than the animation of 50 + nodes individually, also how better would be the network links that connect the nodes (as in the example), so that they follow the nodes where they (this movement can be random).
Any help appreciated
Thank you

creation of eBook and EPUB Best Practices guide
I plan to convert the EPUB format for display on eReaders in my book, but I can't find a set of guidelines. I ran across a reference to a "EPUB best practices guide", but I was not able to find it. Anyhone knows where it is?
My book is in InDesign CS5, and I was the creation of PDF files for the eBook version. I would be very interested in his comments on the advantages and disadvantages of the EPUB. I understand that the page size will be smaller (it is now 8.5 x 11) and images (there are many of them) will be online. Is there anything else I should know before I plunge into that?

Best practices for .vmx
We are moving a few guests of NetApp storage to a new VNX. NetApp best practices (when we started with them) was to separate hard drives containing BONES and data from the virtual machine configuration file, newspapers, clings. newspapers, etc. VMWare recommends the. VMDK for vm and OS configuration files be on the same data store. From a point of view of the administration, it would be easier to follow the recommendation of VMware, but it would not conflict with features such as compression and dedup VNX storage? Exchange files for example would not be entirely deduped.
I'm probably a more conservative person and use thick provisioning, unless I am forced to do otherwise. If time permits I even create virtual disks "Eager to zero thick" which concentrates hard at the time of creation, rather than files in production. It is also the recommended method to prepare the virtual disks for data bases for example.
I'm not saying a provisioning is not useful, but it really depends on the environment and the ability to quickly add additional storage if necessary.

DTS and independent discs.
Global: How activate DTS move independent disks on vSphere 6.x device
-For some reason, we create all the VM with a persistent independent drive.
-We would like to 'solidarity hard disks.
In this case StorageDRS is unable to do its job, create a recommendation and migrate disks of one volume to another (all VM contains DTS unable to move independent labels and independent labels).
There is a cheat for vSphere 5.x - "a vpxd.cfg option sdrs.disableSDRSonIndependentDisk. "When specified and set to false, storage DRS will move to independent disks" (q) DTS Interview Questions | Virtual reality
> Note: this only works for independent non-shared drives.
Yes, it's ok, we don't have all the independent shared disks.
But the file is modified in vSphere 6.x vpxd.cfg format device, now it is of type xml.
And I still can't find how we can enable this option.
Help, please.
OK, after a bunch of tests, I found, the buildings should work.
Must insert in to before /etc/vmware-vpx/vpxd.cfg "" following lines:
fake and then restart the service vmware-vpxd (beware, you have lost connection to vcenter in this time).

Best practices for vCenter 5.1 with Microsoft SQL Server 2008 R2
I am looking for a best practices or really any documentation on configuring vCenter 5.1 with a SQL Server 2008 R2 database. I see that SQL Server 2008 R2 is supported, but that's all. Any help is appreciated.
Unless you have a huge (and I mean huge) environment, the vCenter database in general is not that big of a deal or go-getter and was apparently not deemed worthy for some secret magic tips because of this.
