Chapter 5. Completing networking, clustering, and storage
access setup
The NAS Gateway 300 uses Microsoft Cluster Server (MSCS) software to provide
clustering technology for your storage. Clustering ensures availability of the storage,
regardless of individual component failure.
After installing the clustering function, you can use Cluster Administration to set up
the failover function. Then, if a node or a node's component were to fail, the NAS
Gateway 300 detects the failure and begins a failover process in less than 10
seconds, and completes the process within 60 seconds. Failover/Failback includes
Active/Active support for the CIFS and NFS protocols.
Active/Active support is available for HTTP and FTP. See the online cluster
administration guide for this procedure.
Novell NetWare and Apple Macintosh shares are available on both nodes, but not
through clustering services. If either node fails, the shares become unavailable until
the node is brought back up.
This chapter gives the details for installing and initially configuring MSCS on the
NAS Gateway 300. Administrative concepts and procedures are provided in the
online help and at the following Web sites:

Networking setup

Attention:
joining node is shut down (see "Shutting down and powering on the NAS Gateway
300" on page 87 for more information on shutting down the NAS Gateway 300).
This is required to prevent corruption of data on the shared storage devices.
Corruption can occur if both nodes simultaneously write to the same shared disk
that is not yet protected by the clustering software.
Note: After you complete this procedure on the first node, you must complete it on

Configuring the interconnect (private) network adapter

To configure the interconnect (private) network adapter, perform the following steps
on both nodes. The Private connection is the "heartbeat" interconnect for the
cluster.

Before you install cluster services on the first node, make sure that the
the joining node with the first node shut down.
1. Right-click My Network Places and then select Properties.
2. Select the network connection that uses the integrated Ethernet controller.
3. Right-click the adapter icon and click Properties.
4. Click Configure, select the Advanced tab, and verify that the following
characteristics are set:
