Hardware and Software Requirements for Clustering
All vSphere MSCS configurations require certain hardware and software components.
The following table lists hardware and software requirements that apply to all vSphere MSCS
configurations.
Table 1‑1. Clustering Requirements
Component Requirement
Virtual SCSI adapter LSI Logic Parallel for Windows Server 2003.
LSI Logic SAS for Windows Server 2008 SP2 and above.
VMware Paravirtual for Windows Server 2008 SP2 and above.
Operating system Windows Server 2003 SP1 and SP2, Windows Server 2008 SP2 above releases. For supported guest
operating systems see Table 6‑2.
Virtual NIC Use the default type for all guest operating systems.
I/O timeout Set to 60 seconds or more. Modify
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Disk\TimeOutValue.
The system might reset this I/O timeout value if you re-create a cluster. You must reset the value in
that case.
Disk format Select Thick Provision to create disks in eagerzeroedthick format.
Disk and networking setup Add networking before disks. Refer to the VMware knowledge base article at
http://kb.vmware.com/kb/1513 if you encounter any errors.
Number of nodes Windows Server 2003 SP1 and SP2 : two-node clustering
Windows Server 2008 SP2 and above: up to five-node clustering
For supported guest operating systems see Table 6‑2.
NTP server Synchronize domain controllers and cluster nodes with a common NTP server, and disable host-based
time synchronization when using clustering in the guest.
Supported Shared Storage Configurations
Different MSCS cluster setups support different types of shared storage configurations. Some setups
support more than one type. Select the recommended type of shared storage for best results.
