Before installing the NEC ExpressCluster software, you must prepare the servers.
- Make sure that each server has two network cards and two physical hard disks.
- Configure your first hard disk with one partition only. It will be used for your operating system and software.
Configure your second hard disk with two partitions. One is called the cluster
partition (64 MB raw) and the other is called the data partition (40 GB or more, NTFS).
The data partition will contain Security Center’s SQL database files as well as the
server’s configuration files. This data will be mirrored between the two servers.
IMPORTANT: Not only must the partitions be identical on both servers, but the drive letters assigned must also be identical.
Create the following folders on the data partition for mirroring:
NOTE: In this example “N:” is the drive letter assigned to your mirrored data partition. The folder N:\VertX is only necessary if you are using HID VertX controllers.
- N:\Genetec Security Center 5.9\ConfigurationFiles
- If your system has more than 1,000 entities, or requires extensive reporting, a third disk should be configured with another cluster partition and data partition. SQL’s *.ldf files will be clustered from one disk and SQL’s *.mdf files will be clustered from another physical disk. This step is added for performance stability in larger systems.
Install the same operating system on both servers.
Refer to the NEC ExpressCluster system requirements located at: http://support.necam.com/EnterpriseSW/EC/.
- In Windows, rename the first network card as “Public”. This is the network interface that will accept incoming client connections. Repeat on the second server.
- Rename the second network card as “Private” or “Interconnect”. This is for the dedicated interconnection between the two clustered servers. Repeat on the second server.
Order the Public and Private network interfaces as follows:
IMPORTANT: The network interface on the Private network must be Window’s first available network interface.
- Log on to the first node in the cluster using an administrative Windows account.
- Click ncpa.cpl. , and type
In the Network Connections window, click the
Advanced menu, and then click Advanced
Tip: If the Advanced menu does not appear at the top of the window, press Alt.
- In the Connections list, select the Private network connection, and use the arrow buttons on the right to bring it to the top of the list.
- Click OK.
- Repeat the steps on all remaining cluster nodes.
- On each server, configure the Public network card to use the same IP subnet.
- On each server, configure Private network card to use the same IP subnet.
Disable all network card features of the Private NIC except TCP/IP version 4
(and, if it appears in the list, the driver).
- From the command line, test whether the two servers nodes can ping each other over their public interface and over their private interface.
