As with any update to ESX, make sure you do it in the proper order. First upgrade vCenter and your database and then update each of your hosts. Insights ESX 3. Here are some of the highlights: ESX 3. For example, you will need to have vCenter updated to at least Update 3 in order to be able to use it to manage ESX 3. You can now enable the Enhanced vmxnet driver for bit operating systems. There's no need to share access or a common super user account in order to perform administrative tasks.
This logging ensures user accountability and makes it easy to audit user activity. VMware vSphere live migration allows you to move an entire virtual machine from one physical server to another, without downtime.
Customers can migrate live virtual machines across clusters, distributed switches, vCenters and over long distances of up to ms RTT. Once added, Active Directory handles user authentication and removes the need to create local user accounts on each host. The Auto Deploy library centrally stores all vSphere host images.
Administrators can automatically provision new hosts based on user-defined rules and host rebuilds are as simple as a reboot. The firewall engine allows administrators to define port rules for services. Additionally, you can specify IP ranges or individual IP addresses that can connect to host services. In terms of performance, virtualization imposes a cost in the additional work the CPU has to perform to virtualize the underlying hardware.
Instructions that perform this extra work, and other activities that require virtualization, tend to lie in operating system calls. In an unmodified operating system, OS calls introduce the greatest portion of virtualization "overhead". VMware has been busy what with everything happening right now. The following information provides highlights of some of the enhancements available in this release of VMware Infrastructure Note: Not all combinations of VirtualCenter and ESX Server versions are supported and not all of these highlighted features are available unless you are using VirualCenter 2.
VirtualCenter 2. Alarms can now be configured to trigger when host health degrades. Guided Consolidation now provides administrators with the ability to filter the list of discovered systems by computer name, IP address, domain name or analyzing status. Administrators can also choose to explicitly add physical hosts for analysis, without waiting for systems to be auto-discovered by the Consolidation wizard.
Systems can be manually added for analysis by specifying either a hostname or IP address. Multiple hostnames or IP addresses, separated by comma or semi-colon delimiters, may also be specified for analysis.
Systems can also be manually added for analysis by specifying an IP address range or by importing a file containing a list of hostnames or IP addresses that need to be analyzed for consolidation. Guided Consolidation also allows administrators to override the provided recommendations and manually invoke the conversion wizard.
Therefore, administrators are no longer required to power off a virtual machine in order to create a clone of it. You can now automatically authenticate to VirtualCenter using your current Windows domain login credentials on the local workstation, as long as the credentials are valid on the VirtualCenter server.
This capability also supports logging in to Windows using Certificates and Smartcards. Login Not a member?
