Network Card Bonding On CentOS

Bonding is the same as port trunking. In the following I will use the word bonding because practically we will bond interfaces as one. Bonding allows you to aggregate multiple ports into a single group, effectively combining the bandwidth into a single connection. Bonding also allows you to create multi-gigabit pipes to transport traffic through the highest traffic areas of your network. For example, you can aggregate three megabits ports into a three-megabits trunk port. That is equivalent with having one interface with three megabytes speed. Where should I use bonding? ----------------------------------------------------------------------------------------------------------- You can use it wherever you need redundant links, fault tolerance or load balancing networks.

Install vSphere 4.1 Update Management display "ODBC 32bit"

Install the ODBC drivers. For Microsoft SQL Server database servers, install the 64-bit database ODBC drivers on your Microsoft Windows system. When you install the 64-bit drivers, the 32-bit drivers are installed automatically. For Oracle database servers, install the 32-bit database ODBC drivers on your Microsoft Windows system. Run the 32-bit ODBC Administrator application, located at [WindowsDir]\SysWOW64\odbcad32.exe. Use the application to create your DSN. You will now have a DSN that is compatible with the Update Manager server. When the Update Manager installer prompts you for a DSN, you should select the 32-bit DSN. Note: The Microsoft SQL Server 2005 Express database package is installed and configured when you select Microsoft SQL Server 2005 Express as your database during the VMware vCenter Update Manager installation or upgrade. No additional configuration is required.
