book.book Page 11 Monday, April 19, 2010 5:06 PM Dell Remote Access Controller/Modular Chassis or Chassis Management Enclosure The Dell Remote Access Controller/Modular Chassis or Chassis Management Enclosure (DRAC/MC or CMC) is a management module located in the back of the blade server system chassis that provides all of the chassis management functionality. The DRAC/MC or CMC provides serial and out-of-band Ethernet management ports to allow for management of the chassis and some basic blade functions.
book.book Page 12 Monday, April 19, 2010 5:06 PM Server Modules Depending on the PowerEdge blade server module you choose for your cluster, the number of available expansion ports and dual inline memory modules (DIMMs) varies. Table 1-1 provides details about the supported PowerEdge server modules and PowerEdge server enclosures. Table 1-1. PowerEdge Blade Server Features Server Enclosure 1855/1955 M1000e Supported blade server modules PowerEdge 1855, 1955 See the Support Matrix at dell.
book.book Page 13 Monday, April 19, 2010 5:06 PM Gigabit or 10 Gigabit Ethernet The following are the Ethernet network connections available, depending on your configuration: • Public connection from the server modules to the public network • Private node-to-node connection between the server modules for the private network • iSCSI connection between the server modules and storage system(s). For more information, see "Supported Cluster Configurations" on page 16.
book.book Page 14 Monday, April 19, 2010 5:06 PM Ethernet Pass-Through Module The Ethernet pass-through module provides a non-switched connection between the server modules and an external Ethernet device. Table 1-2 summarizes the supported Ethernet module configurations. Table 1-2.
book.book Page 15 Monday, April 19, 2010 5:06 PM For more information about the Fibre Channel modules, see your Dell PowerEdge system documentation. Fibre Channel Switch Module The Fibre Channel switch module provides a switched connection between the Fibre Channel daughter card in the server modules and a supported Fibre Channel device. The switch module functions as a director, mapping requests and responses between the interconnected devices.

book.book Page 25 Monday, April 19, 2010 5:06 PM Cabling Your Blade Cluster Hardware 2 NOTE: The cluster nodes represent the individual server modules in your Dell™ PowerEdge™ server enclosure. The designations namely, node 1 and node 2 and the server enclosure are used for illustrative purposes only. The system and the storage components in your cluster configuration may vary.
book.book Page 26 Monday, April 19, 2010 5:06 PM Figure 2-1.
book.book Page 27 Monday, April 19, 2010 5:06 PM Cabling the Private Network The private (heartbeat) network is used for sharing cluster health and status information between the cluster nodes. Each cluster node connects to the private network through the second embedded NIC port on the server module system board. The second NIC port connects to the internal connections in the system chassis to the second Ethernet switch module or the associated port in the corresponding Ethernet pass-through module.

book.book Page 29 Monday, April 19, 2010 5:06 PM Cabling the Storage Systems This section provides information for connecting your cluster to a storage system in a direct-attached configuration, or to one or more storage systems in a network-attached configuration. NOTE: The cluster nodes represent the individual server modules in the PowerEdge server enclosure. The designations namely, node 1 and node 2 and the server enclosure are used for illustrative purposes only.
book.book Page 30 Monday, April 19, 2010 5:06 PM Figure 2-2 shows an example of a direct-attached, two-node cluster configuration using redundant connections to server modules 5 and 6. See your Dell PowerEdge system documentation for more information about the Fibre Channel/Ethernet pass-through module.

book.book Page 32 Monday, April 19, 2010 5:06 PM Network-Attached Cluster A network-attached cluster is a cluster configuration where all cluster nodes are attached to a single storage system or to multiple storage systems through a network using a redundant switch fabric. Network-attached cluster configurations provide flexibility, expandability, and performance with either iSCSI or Fibre Channel storage arrays.
book.book Page 33 Monday, April 19, 2010 5:06 PM Figure 2-3.
book.book Page 34 Monday, April 19, 2010 5:06 PM NOTE: You can connect additional cables from the fibre channel switches to the storage system, if there are available front-end fibre channel ports on the storage processors.

book.book Page 37 Monday, April 19, 2010 5:06 PM Cabling One PowerEdge Server Enclosure to Multiple Storage Systems You can increase your cluster storage capacity by attaching two storage systems to your cluster using a redundant switch fabric. PowerEdge cluster systems can support configurations with two storage units attached to clustered servers.
book.book Page 38 Monday, April 19, 2010 5:06 PM NOTE: If you are using other Dell/EMC storage systems for the configuration shown in Figure 2-6, you can also connect the remaining iSCSI ports 2 iSCSI and 3 iSCSI (not shown) depending on the required level of redundancy. Cabling One PowerEdge Server Enclosure to a Tape Library To provide additional backup for your cluster, you can add a tape backup device to your cluster configuration.

book.book Page 40 Monday, April 19, 2010 5:06 PM For high availability, each PowerEdge server enclosure requires direct paths to the attached storage systems. This configuration ensures that all running applications are available if one of the PowerEdge server enclosures needs to be shut down for maintenance. Figure 2-8 shows two PowerEdge 1855/1955 server enclosures cabled to one supported Dell/EMC storage system in an iSCSI configuration.

book.book Page 43 Monday, April 19, 2010 5:06 PM Network-Attached Cluster Connected to an External Fabric External Switches incorporate the external switch network or SAN connected to the PowerEdge Enclosure through the pass-through modules or switch modules. These configurations allow you to extend the Fibre Channel/iSCSI network by connecting more storage systems. The following sections provide examples for these configurations.
