What's New in the ESX Server 3.0.1/VirtualCenter 2.0.1 Release

This release of VMware Infrastructure, comprised of ESX Server and VirtualCenter, offers the following improvements:

  • Support for selected 64-bit guest operating systems. For more information on 64-bit guest operating system support including important hardware requirements, see Details of What's New and Improved in VMware Infrastructure 3 and the Systems Compatibility Guide for ESX Server 3.x.

  • Improved upgrade support from Virtual Infrastructure 2 to VMware Infrastructure 3. For more information, see the Installation and Upgrade Guide.

  • Introduction of the esxupdate utility for upgrade deployment. For more information, see the Installation and Upgrade Guide.

  • NEW: Support for Microsoft SQL Server 2005 (SP1 only) as a database for VirtualCenter. See Requirements for Running VirtualCenter with MS SQL 2005 (KB 6565318) for information on using this database with VirtualCenter.

  • Support for servers based on the AMD 2000/8000 and Intel Xeon 7100 (codename Tulsa) series of processors.

  • Enablement of QLogic QLA 4050/4052 hardware iSCSI HBAs. See the ESX Server 3.x I/O Compatibility Guide and the ESX Server 3.x Storage/SAN Compatibility Guide for the latest support status because testing and certification is not yet complete at the time of these release notes publication.

  • Support for iSCSI arrays such as EqualLogic PS300 and NetApp FAS3000.

  • Support for Symmetric Multiprocessing (SMP) on Windows XP virtual machines.

  • Critical bug fixes related to ESX Server 3.0 and VirtualCenter 2.0.

  • Enablement for German and Japanese product versions.

    Note: Technical support services for VMware Infrastructure are currently delivered in English. German and Japanese speaking Support Engineers are available in a limited capacity during the operating hours of the local support center. For more information, see VMware local language support.

ESX Server 3.0/VirtualCenter 2.0 Feature Highlights

The ESX Server 3.0 and VirtualCenter 2.0 product lines offer an array of new features and enhanced functionality. Here are some highlights:

  • NAS and iSCSI Support
    ESX Server 3.0 can store virtual machines on NAS and iSCSI. iSCSI LUNs, like Fibre Channel LUNs, can be formatted with the VMware file system (VMFS). Each virtual machine resides in a single directory. Network attached storage (NAS) appliances must present file systems over the NFS protocol for ESX Server to be able to use them. NFS mounts are used like VMFS with ESX Server creating one directory for each virtual machine. iSCSI enabled through a software initiator (100% implemented as a software layer over TCP/IP) is fully supported in this release.

  • Clusters
    A cluster is a collection of hosts that can be managed as a single entity. The resources from all the hosts in a cluster are aggregated into a single pool. A cluster looks like a stand-alone host, but it typically has more resources available.

  • VMware DRS
    VMware DRS allows resources from all hosts in a cluster to be treated as a single, aggregated pool. When changes occur in the environment, DRS can tune the resource scheduling on individual hosts as well as use VMotion to rebalance workload across hosts in the cluster. When a virtual machine is powered on, DRS calculates the optimal host on which to start it, given current resource levels and the resource configuration of the new virtual machine.

  • Resource Pools
    A resource pool provides a way of subdividing the resources of a stand-alone host or a cluster into smaller pools. A resource pool is configured with a set of CPU and memory resources that are shared by the virtual machines that run in the resource pool. Resource pools can be nested.

  • VMware HA
    VMware HA (HA) increases the availability of virtual machines by detecting host failures and automatically restarting virtual machines on other available hosts. HA operates on a set of ESX Server 3.0 hosts that have been grouped into a cluster with HA enabled.

  • 64-Bit Virtual Machines
    64-bit guest operating systems are experimentally supported and visible in the Virtual Infrastructure Client interface, with full support available in future VI3 releases.

  • Remote CD/Floppy
    Using either the Virtual Infrastructure Client or Virtual Infrastructure Web Access, a virtual machine can access a CD or floppy device from the client's machine.

  • Hot-Add Virtual Disk
    ESX Server 3.0 supports adding new virtual disks to a virtual machine while it is running. This is useful with guest operating systems capable of recognizing hot-add hardware.

  • New Version of the VMware File System: VMFS 3
    There is a new generation of VMFS in ESX Server 3.0. Scalability, performance, and reliability have all improved. Furthermore, subdirectories are now supported. ESX Server system will create a directory for each virtual machine and all its component files.

  • VMware Consolidated Backup
    Consolidated Backup enables offloaded and impact-free backup for virtual machines running on an ESX Server system by allowing traditional file-based backup software to leverage VMware virtual machine snapshot technology and efficient SAN-based data transfer.

  • Virtual Infrastructure Client
    The VirtualCenter Client has been renamed the Virtual Infrastructure Client or VI Client to convey its ability to connect to a VirtualCenter Management Server or to individual ESX Servers. When connected to VirtualCenter 2.0, the VI Client provides full monitoring and management of multihost configurations and multihost functionality, such as VMotion, DRS, and HA. When connected to ESX Server 3.0, the VI Client provides the subset of functionality needed to manage the virtual machines and configurations of single hosts. In both cases, the VI Client contains all the functionality previously available through the separate Web-based Management User Interface (MUI) in ESX Server Server 2.x and provides an interface to configure ESX Server 3.0.

  • New Guest SDK Available

  • The VMware Guest SDK allows software running in the guest operating system in a VMware ESX Server 3.0 virtual machine to collect certain data about the state and performance of the virtual machine. Download the Guest SDK package from www.vmware.com/support/developer/

  • Tools Auto-Upgrade

  • VMware Infrastructure 3 (ESX Server 3.0/VirtualCenter 2.0) supports the ability to install or upgrade VMware Tools on multiple virtual machines at the same time without needing to interact with each virtual machine. Detailed instructions are provided in the Installation and Upgrade Guide.

  • Licensing Scheme

  • ESX Server 3.0 and VirtualCenter 2.0 introduce new licensing mechanisms based on FlexNet mechanisms. The first option is called "License Server Based" licensing and is intended to simplify license management in large, dynamic environments by allowing licenses to be managed and tracked by a license server. The second option is called "Host Based" licensing and is intended for smaller environments or customers preferring to keep ESX Server systems decoupled from a license server.

    Use "License Server Based" license files to unify and simplify the license management of many separate VirtualCenter and ESX Server licenses by creating a pool of licenses centrally managed by a license server. Licenses for the VirtualCenter Management Server and for the VirtualCenter add-on features, such as the VirtualCenter Management Agent, VMotion, VMware HA, and VMware DRS are only available in this form.

    "Host Based" license files are not centrally managed and not dynamically allocated but might be placed directly on individual ESX Server hosts. Only the licenses for ESX Server and VMware Consolidated backup are available in this alternative form.

  • VMware Experimental Feature Support Definition

  • VMware includes certain experimental features in some of our product releases. These features are there for you to test and experiment with. We do not expect these features to be used in a production environment. However, if you do encounter any issues with an experimental feature, we are interested in any feedback you are willing to share. Please submit a support request through the normal access methods. You will receive an auto-acknowledgement of your request. We cannot, however, commit to troubleshoot, provide workarounds, or provide fixes for these experimental features.
