What is the maximum number of vCPU can I connect to a virtual computer?
Currently, we are conducting a cluster of 3 ESX host. 2 of them run Xeon Dual Core Pro 7140 M and the rest works a Quad-Core Intel Xeon X 5460 CPU.
HT enabled processor Xeon Dual Core Pro 7140M. In this way, each female, it shows that 4 logical CPU.
We would like to know if we can assign 4vCPU to a virtual machine (as required by a server administrator) WHERE we can assign only 2 vCPU maximally?
Thank you
I think you should spend some time reading about VMware resources management guide and have a good operation of a CPU scheduling understandings and best practices dealing with vSMP. As everyone says, it would be unwise to have a virtual machine running 4vCPU or 8 vCPU and I did not see a need for anything that is 8 vCPU but does not mean that it cannot. It would be nice if you can tell us your current use of the server/application and details of the charge and that would quickly determine 2vCPU is pretty good. The vCPU more assigned to the virtual machine, takes more time to achieve your requests because it must have enough carrots to do and called "Co planning." I have attached the guide so that you can read a few details. http://www.VMware.com/PDF/vi3_35/esx_3/R35/vi3_35_25_resource_mgmt.PDF
It wouldn't surprise if you complain about performance issues when you have tons of 4vCPU or virtual 8vCPU running in the cluster. Always start with 1vCPU and growth like him.
If you found this information useful, please consider awarding points to 'Correct' or 'useful '. Thank you!!!

What is the maximum number of characters that a 2D barcode can have with the symbology PDF417 Matrix? How to solve the problem of code bar having too much data? I'm incorporating data of the bar code under a button field. But when the data is large, the problem occurs.
Apparently the theoretical capacity of the PDF417 barcode is 1850 characters or numbers in 2710. Of course, the actual capacity depends on the size - more square inches, more data. But before the theoretical limit, that you can reach practical limits in scanning technology so test carefully with all models of planned barcode scanner.

What is the maximum number of carrots that I can attribute to a RHEL guest?
What is the maximum number of carrots that I can attribute to a RHEL guest? We have a data center by telling us that they can not affect more than 4 cores in the guest OS, even if the guest OS is reliever of suposto the entire physical host (IE, it's the only host on the ESX node).
We have 16 cores on the physical machine, and they tell us, that we can not have more than 4 in total in a single instance of comments.
4vCPU per guest is max

What is the maximum number of data warehouses in a system of Vcenter?
I had a look at highs of configuration in http://www.VMware.com/PDF/vSphere4/R40/vsp_40_config_max.PDF , he lists100 in the section of SMI-S
SMI-S section list max number of ESX host as 100, although it is 300 in the maximum of vcenter server. Should I look for in the section of SMI-S?
Only if you plan to use SMI - if she does not go with the maximum rates for vCenter - and you are correct to look at the number of hosts since it is the ESX hosts that communicate to the SAN not vCenter-

What is the maximum number of supported in a PDF document hyperlinks?
How will I know how many hyperlinks, there is in a PDF document?
There is no limit per document. Links (with hyperlinks to URLS) are not stored all together, but stored for each page. There is no limit per page either but I would begin to worry about performance if there is more than 100 per page.
Just for fun, I checked how many links there are in the PDF file, I use most often (of about 6000 pages). ; There are 52 000 links inside.

What is the maximum number of files that I can place in a subfolder in FAT32
FAT32 maximum number of files in a folder
The maximum size of a directory of FAT32 is 32-bit 65536 entries. A file it will take at least 2 entries according to the length of the file name. Long filenames are stored in 16-bit UNICODE characters, and only thirteen characters are stored in the directory entry.
Big directories should be avoided for performance reasons. For example, adding a file requires all existing entries to be analysed in order to avoid duplicates.
FAT32 specification can be downloaded here:

What is the maximum number of photos I can stack them in a group?
On Windows 10, second gen Core i7 with 24 GB of RAM using Lightroom 6.1.1. Trying to stack a little more than 1000 pictures. Lightroom not responding initially, then seems to have completed the task, then according to the use of Task Manager ~ 16% (4 hyper threaded cores) CPU, 2, 3 GB of RAM not used, no hard disk activity. This last for hours if I let is sit (watch a movie). Out of Lightroom, it disappears and continues to consume CPU until I have killed him. Go back to the top of Lightroom and no tails do occur. Tried this several times. Tested with an own catalog as well.
There is no issue about a maximum number of pictures that can be stacked in a single stack.

What is the maximum number of vNIC on a vSphere VM?
The maximum configuration said 10, but I can only add 4. 7 material seems to have the same limitations as 4 material:
6 virtual slots PCI, taken by the video card, 5 is available for the vSCSI and controllers vNIC, not more than 4 max from one type to the other. The maximum configuration guide cannot be bad can? Or am I missing something?
Make sure that the hardware has been upgraded - I've had no problems add more than 4 vNIC with a virtual machine that has modernized equipment.
