VMware ESX Server now supports Symmetric Multiprocessing (SMP) virtual machines, with single or dual virtual CPUs. Note: You only will be able to create dual-virtual CPU virtual machines if you have purchased the VMware Virtual SMP for ESX Server product. In addition, the ESX Server machine must have at least 2 physical processors. You cannot create dual-virtual CPU virtual machines on servers with a single processor. For more information on the VMware Virtual SMP for ESX Server product, contact VMware or your authorized sales representative. ESX Server 2.0 includes support for the following IBM and HP servers: NIC teaming enables you to group two through ten physical network interface controllers (NICs) into one single virtual network device. By binding all these physical NICs together, you can help ensure network connectivity to the server (fail-over) and improve network performance (load balancing). ESX Server 2.0 maximizes storage area network (SAN) availability by providing multipathing or automatic path failover in case of HBA, switch or storage controller failure. For information on supported SAN storage devices and configurations, download the VMware ESX Server SAN Compatibility Guide from the VMware Web site at www.vmware.com/support/esx2. ESX Server 2.0 includes a new VMFS version 2 (VMFS-2). VMFS-2 has the ability to span multiple partitions and the ability for multiple ESX Servers (and the virtual machines on these servers) to access VMFS-2 concurrently. Overall, file system operations in the /vmfs directory are faster for backup and restore tasks. ESX Server 2.0 introduces a new VMware Management Interface that contains improved navigation, better performance and an easier-to-use interface. ESX Server 2.0 includes support for Microsoft® Windows® XP Professional, Microsoft Windows Server 2003, Red Hat Linux® 9.0 and SuSE Linux 8.x. ESX Server 2.0.1 includes support for Red Hat Enterprise Linux 3.0 and support for Novell NetWare 6.5 and Novell NetWare 5.1 operating systems. See Supported Guest Operating Systems for a complete list of supported guest operating systems in ESX Server 2.0. ESX Server 2.0 supports the LSI Logic SCSI virtual adapter. By default, ESX Server assigns a virtual BusLogic SCSI adapter to Linux, Microsoft Windows NT® 4.0, Windows 2000 or Windows XP Professional guest operating systems. Similarly, ESX Server assigns a virtual LSI Logic SCSI adapter to Windows Server 2003 guests. You change these default settings by editing the virtual machine's configuration file. You can specify a minimum CPU percentage, a maximum CPU percentage or both for each virtual machine. The minimum CPU percentage represents an absolute fixed lower limit while the maximum CPU percentage represents an absolute fixed upper limit. For example, if you create a virtual machine and a minimum CPU percentage of 30% and a maximum CPU percentage of 80%, then this virtual machine will always have at least 30%, and never more than 80%, of a physical CPU's resources. ESX Server 2.0 includes support for VMware Scripting APIs. To download these packages, go to the ESX Server Download page, www.vmware.com/download/esx of the VMware Web site. The API packages are:
