In Datacenter Edition, the maximum
supported cluster size has been increased from 4-nodes in Windows 2000, to
8-nodes in Windows Server 2003.
In Enterprise Edition, the maximum
supported cluster size has been increased from 2-nodes in Windows 2000 Advanced
Server to 8-nodes in Windows Server 2003.
Server clusters running Windows Server
2003, Enterprise Edition or Datacenter Edition integrate with the Microsoft
Active Directory service.
This integration ensures that a
"virtual" computer object is registered in Active Directory. This
allows applications to use Kerberos authentication and delegation to highly
available services running in a cluster. The computer object also provides a
default location for Active Directory-aware services to publish service control
points.
Server clusters are fully supported on
computers running the 64-bit versions of Windows Server 2003. Windows Server 2003
supports Encrypting File System (EFS) on clustered (shared) disks.
