Cabling Your Public and Private Networks The network adapters in the cluster nodes provide at least two network connections for each node. These connections are described in Table 2-1. Table 2-1. Network Connections Network Connection Description Public Network All connections to the client LAN. At least one public network must be configured for mixed mode (public mode and private mode) for private network failover.
Figure 2-2. Example of Network Cabling Connection public network private network adapter private network cluster node 1 cluster node 2 Cabling Your Public Network Any network adapter supported by a system running TCP/IP may be used to connect to the public network segments. You can install additional network adapters to support additional public network segments or to provide redundancy in the event of a faulty primary network adapter or switch port.
Table 2-2. Private Network Hardware Components and Connections Method Hardware Components Connection Network switch Gigabit or 10 Gigabit Depending on the hardware, Ethernet network connect the CAT5e or CAT6 adapters and switches cables, the multimode optical cables with Local Connectors (LCs), or the twinax cables from the network adapters in the nodes to a switch.
Cabling Storage for Your Direct-Attached Cluster A direct-attached cluster configuration consists of redundant Fibre Channel host bus adapter (HBA) ports cabled directly to a Dell PowerVault MD36x0f storage system. If a component (for example, port, cable, or the storage controller) fails in the storage path, the MPIO software automatically re-routes the I/O requests to the alternate path so that the storage array continues to operate without interruption.
Figure 2-3. Direct-Attached Cluster Configuration public network cluster node cluster node private network Fibre Channel Fibre Channel connections connections storage system Cabling Your Cluster Hardware...
Cabling a Cluster to a Dell PowerVault MD36 0f Storage System Each cluster node attaches to the storage system using two Fibre optic cables with duplex local connector (LC) multimode connectors that attach to the HBA ports in the cluster nodes and the MD36x0f RAID controller module ports in the MD36x0f storage system.

Figure 2-5 shows a four-cluster node connected to two RAID controller modules. Since each cluster node has redundant paths, loss of a single path still allows access to the storage array through the alternate path. Figure 2-5. Cabling a Four-Node Direct-Attached Cluster to a PowerVault MD36 Storage System PowerVault MD360x0f series storage array Corporate, public, or...
Cabling Two Two-Node Direct-Attached Clusters to an MD36x0f Storage System The following steps are an example of how to cable a two two-node cluster. 1 In the first cluster, connect cluster node 1 to the storage system: Install a cable from cluster node 1 HBA port 0 to the Fibre Channel port on the MD36x0f RAID controller module 0, port In-0.
Similar cabling concepts can be applied to clusters that contain a different number of nodes. NOTE: The connections listed in this section are representative of one proven method of ensuring redundancy in the connections between the cluster nodes and the storage system. Other methods that achieve the same type of redundant connectivity may be acceptable.

Storage Subsystem The virtual disks in your shared storage subsystem must be configured into disk groups or virtual disks using the Dell PowerVault MDSM software. All virtual disks, especially if they are used for the quorum resource, must be bound and must incorporate the appropriate RAID level to ensure high availability.
Naming and Formatting Drives on the Shared Storage System Each virtual disk being created in the PowerVault Modular Disk Storage Manager becomes a physical disk in Windows Disk Management. For each physical disk, perform the following: • Write the disk signature •...
access a given physical disk resource at a time. Therefore, if a disk is partitioned and contains multiple NTFS volumes, concurrent access to different volumes is only possible from the cluster node controlling the physical disk resource. If two NTFS volumes need to be controlled by different nodes, these volumes must reside on separate disks.
For more information, see the Premium Feature Activation card that shipped along with your Dell PowerVault MD3600f or MD3620f storage system. These premium features increase the high availability for your cluster solution.
CAUTION: Avoid mapping the Snapshot Virtual Disk to more than one node in the cluster at any point of time. The Snapshot Virtual Disk is not managed by Failover Cluster Manager, so mapping the Snapshot Virtual Disk to the host group or both nodes in the cluster may allow both nodes to access data concurrently and thus cause data corruption.
Remote Replication feature is deactivated. A dedicated zone on each Fibre Channel switch is also required.
