RightFax 8.5 Installation Guide 41
Appendix A
Installing RightFax in a
Windows NT 4.0 or
Windows 2000 Cluster
System Requirements
Installing RightFax in a Windows cluster environment requires that you have two servers that are
on the Microsoft Clustering Hardware Compatibility List (located on the Microsoft Web site)
running Windows 2000 Advanced Server or Windows NT 4.0 Cluster Server. You must also have
two network cards. A hardware RAID controller is required for external array and is recommended
for internal array. Windows Cluster Service must be installed, configured, and operational. There
also must be an external RAID array running either SCSI or fiber channel.
Configuring the Cluster Group
All of the clustered RightFax resources must be maintained in a single cluster group. This provides
complete failover protection in the event of individual resource failures. This cluster group must
also include a disk resource, a server name resource, and an IP address resource. The combination
of these core resources creates a virtual RightFax server. Configure the cluster group to have a
preferred server and to allow fail-back.
The default group created during the Cluster service installation, named “Cluster Group,” may also
be used for the RightFax resources. In this case, the quorum drive is typically used as the shared
installation drive for the RightFax software. While this approach may add complexity to recovery
procedures in the event of a Cluster service or disk device failure, it will not affect configuration or
performance, and it is a good choice when hardware resources are limited to a single RAID
controller.
Configuring RightFax BoardServers
It is strongly recommended that no RightFax BoardServers be installed on the clustered hardware.
Phone lines and T1 lines cannot be clustered and will not failover in the event of a hardware
problem. Captaris recommends that you use remote BoardServers, connecting to the virtual
RightFax server.
