What's in the Release Notes
The release notes cover the following topics:
Details of What's New and Improved in VI 3.
- 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.
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.
- Creating 64-Bit Virtual Machines
By default, 64-bit guests are now visible in the Virtual Infrastructure
Client interface and marked as "experimental."
- 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
- 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
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.
