Page 13: San-Attached Cluster
EMC PowerPath provides failover capabilities, multiple path detection, and dynamic load balancing between multiple ports on the same storage processor. However, direct-attached clusters supported by Dell connect to a single port on each storage processor in the storage system. Because of the single port limitation, PowerPath can provide only failover protection, not load balancing, in a direct-attached configuration. -

Page 22: Cabling The Storage Systems
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|EMC storage system. Direct-attached configurations are self-contained and do not share any physical resources with other server or storage systems outside of the cluster. - Page 23 (LC) multimode connectors that attach to the HBA ports in the cluster nodes and the storage processor (SP) ports in the Dell|EMC storage system. These connectors consist of two individual Fibre optic connectors with indexed tabs that must be aligned properly into the HBA ports and SP ports.

With the CX3-40f or CX3-80 you can configure four cluster nodes and with CX3-20f you can configure six cluster nodes in a direct attached configuration.
- Page 26 (fourth Fibre Channel port). Cabling Two Clusters to a Dell|EMC Storage System The four fibre channel ports per storage processor on Dell|EMC CX3-40f and CX3-80 storage systems allows you to connect two two-node clusters in a direct-attached configuration. Similarly, the six fibre-channel ports per processor on Dell|EMC CX3-20f storage system allows you to connect three two-node clusters in a direct-attached environment.

Page 41: Installation Overview
Installation Overview Each node in your Dell Failover Cluster must be installed with the same release, edition, service pack, and processor architecture of the Windows Server operating system. For example, all nodes in your cluster may be configured with Windows Server 2003 R2, Enterprise x64 Edition. -
Page 42: Installing The Fibre Channel Hbas
Placing the adapters on separate buses improves availability and performance. For more information about your system's PCI bus configuration and supported HBAs, see the Dell Cluster Configuration Support Matrix on the Dell High Availability website at www.dell.com/ha. Installing the Fibre Channel HBA Drivers For more information, see the EMC documentation that is included with your HBA kit. -
Page 43: Using Zoning In San Configurations Containing Multiple Hosts
Zoning automatically and transparently enforces access of information to the zone devices. More than one PowerEdge cluster configuration can share Dell|EMC storage system(s) in a switched fabric using Fibre Channel switch zoning and Access Logix™. By using Fibre Channel switches to implement zoning, you can segment the SANs to isolate heterogeneous servers and storage systems from each other. - Page 44 If you are sharing a storage system with multiple clusters or a combination of clustered and nonclustered systems (hosts), you must enable EMC Access Logix and Access Control. Otherwise, you can only have one nonclustered system or one PowerEdge cluster attached to the Dell|EMC storage system. Preparing Your Systems for Clustering...

Page 45: Installing And Configuring The Shared Storage System
Fibre Channel topologies allow multiple clusters and stand-alone systems to share a single storage system. However, if you cannot control access to the shared storage system, you can corrupt your data. To share your Dell|EMC storage system with multiple heterogeneous host systems and restrict access to the shared storage system, you can enable and configure the Access Logix software. - Page 46 Access Logix is enabled by configuring the Access Logix option on your storage system. The storage systems are managed through a management station—a local or remote system that communicates with Navisphere Manager and connects to the storage system through an IP address. Using Navisphere Manager, you can secure your storage data by partitioning your storage system arrays into LUNs, assign the LUNs to one or more storage groups, and then restrict access to the LUNs by assigning the storage groups to the appropriate host systems.
-
Page 47: Access Control
Access Control Access Control is a feature of Access Logix that connects the host system to the storage system. Enabling Access Control prevents all host systems from accessing any data on the storage system until they are given explicit access to a LUN through a storage group. - Page 48 Table 3-3. Storage Group Properties Property Description Unique ID A unique identifier that is automatically assigned to the storage group that cannot be changed. Storage group name The name of the storage group. The default storage group name is formatted as Storage Group n, where n equals the existing number of storage groups plus one.
-
Page 49: Navisphere Manager
EMC PowerPath PowerPath automatically reroutes Fibre Channel I/O traffic from the host system and a Dell|EMC CX-series storage system to any available path if a primary path fails for any reason. Additionally, PowerPath provides multiple path load balancing, allowing you to balance the I/O traffic across multiple SP ports. -
Page 50: Enabling Access Logix And Creating Storage Groups Using Navisphere
Enabling Access Logix and Creating Storage Groups Using Navisphere 6.x The following subsection provides the required procedures for creating storage groups and connecting your storage systems to the host systems using the Access Logix software. NOTICE: Before enabling Access Control, ensure that no hosts are attempting to access the storage system. -

10 Click OK. 11 Right-click the icon of your storage system and select Create Storage Group. The Create Storage Group dialog box appears. 12 In the Storage Group Name field, enter a name for the storage group. 13 Click Apply. 14 Add new LUNs to the storage group. - Page 52 Using the Windows Dynamic Disks and Volumes For more information on deploying your cluster with Windows Server 2003 operating systems, see the Dell Failover Clusters with Microsoft Windows Server 2003 Installation and Troubleshooting Guide located on the Dell Support website at support.dell.com.
- Page 53 Naming and Formatting Drives on the Shared Storage System When the LUNs have completed the binding process, assign drive letters to the LUNs. Format the LUNs as NTFS drives and assign volume labels from the first cluster node. When completed, the remaining nodes will see the file systems and volume labels.
- Page 54 Assign drive letters on each of the shared disks, even if the disk displays the drive letter correctly.

Page 55: Optional Storage Features
Optional Storage Features Your Dell|EMC CX3-series storage array may be configured to provide optional features that can be used in conjunction with your cluster. These features include MirrorView, SnapView, and SANCopy. MirrorView MirrorView automatically duplicates primary storage system data from a cluster or stand-alone system to a secondary storage system. -
Page 56: Updating A Dell|Emc Storage System For Clustering
Updating a Dell|EMC Storage System for Clustering If you are updating an existing Dell|EMC storage system to meet the cluster requirements for the shared storage subsystem, you may need to install additional Fibre Channel disk drives in the shared storage system. The size and number of drives you add depend on the RAID level you want to use and the number of Fibre Channel disk drives currently in your system. -
