8-way VM on ESX 4.1 - Win2k8 R2 Standard edition

Today, I had to configure a VM with 8 vCPU's on an ESX 4.1 cluster. The guest OS was Windows Server 2008 R2 Standard Edition. However, after configuring the VM with 8 vCPU's it still only registered 4 vCPU's in the guest OS.

The reason is that both Win2k3 and Win2k8 R2 standard edition only can be configured with four physical CPUs or sockets. By default vSphere 4.0 and 4.1 presents 1 vCPU as one socket.

To bypass this, there is a feature (experimental in 4.0 but supported in 4.1) allowing you to configure multiple cores per socket. See this KB article. This feature has been included in vSphere 5.0 in the GUI.

See this article for comparison of Windows 2003 editions.

See this link for comparison of Windows 2008 edition (look for 'Editions Guide' at the bottom of the page). Or download PDF here.

There are many reasons why you would want to find your computer IP address.some reasons might include, Internet connection problems, setting up a new home network, sharing files over a home network, and so on.

Every device connected to the public Internet is assigned a unique number known as an Internet Protocol (IP) address. IP addresses consist of four numbers separated by periods (also called a ‘dotted-quad’) and look something like 127.0.0.1. Go here for your public Internet IP address lookup.

However sometimes you need to find your computers IP address on your home network. Now days computer networking is very common in the average household and not just used in the office or business work environments. In fact many home computer networks have already upgraded to a wireless setup. If you ever need to change your ip address because of a conflict on your network here’s how…

 

Here are two ways to find your computer IP address:

First Way

1. If you have an Internet connection icon in the bottom right corner of the taskbar, you can double click this to open it.
2. Then choose the support tab at the top.
3. Your IP Address will be there.

Second way

2. Choose Network connections. (Choose Wireless Network for Wireless setups)
3. Right click on your internet connection icon and choose properties.

2. Then from the list choose Internet Protocol (TCP/IP)

This is my Internet Protocol Properties box. I have chosen to Set my IP address to 10.0.0.1 and the default gateway is my modem IP address.

How to find your IP address for your computer in Windows Vista?

How to Find Your Computer Name and Change it

There will be times when you need to know your computers name. This is not the same as your computer username. You might use your computer name to share files and printers on your home network and sometimes the default computer name is just too difficult to remember. This is the number one reason for changing your computer name. If you are using the computer name to setup a shared printer you will need to rename your computer something easy. You do not want a string of numbers and letters.

How to find your computer name and change it?

1. Press the Windows key and the Pause Break button at the same time. How easy is that? Applies to Windows Xp and Vista.
2. Or go to Start menu>control panel>system (For Vista you can get more details by clicking on the items in the left bar menu.)
3. Or go to the Start Menu and right-click on My Computer and select Properties (For Vista its not my Computer but just computer)

To get a similar dialog box, as above, to appear in Vista you need to look a bit further. When you open system properties as in the steps above, you also need to click on a menu item in the left panel. For example, you can click on Advanced Options. This will bring up a dialog box like the Windows XP one.

You can also see your computer name  in System properties as the arrow shows below. And here you can click on change settings to change your computer name.

Where is the name of your computer?

1. Choose computer name from the tab
2. And there it is in small writing…If it is a difficult or overly long name click on change. Change your computer name to something easy. Mine is called ‘server’ See screenshot below.

Can I change the computer name and still keep all of my files?

Changing your computer name will not effect your files on your computer. The will stay where they are, untouched and safe. Changing the name of your computer may effect your network settings. For example if you are sharing a printer and the path to the printer is rizviprinter and you change rizvi to saboo it will not find the printer.

Notes:

• Windows Vista displays the computer name on the first page of the system properties.
• When networking or sharing files you can either use your computer IP Address or your computer name.
• All computers on the Network should have different names and IP address’s to avoid conflicts.
