1 Introduction This guide provides information about deploying Dell PowerVault MD3860f storage arrays. The deployment process includes: • Hardware installation • Modular Disk Storage Manager (MD S.
• Host server — On a host server system, MD Storage Manager and the storage array communicate management requests and event information using in-band or out-of-band connections.
Contacting Dell NOTE: If you do not have an active Internet connection, you can find the contact information on your purchase invoice, packing slip, bill, or Dell product catalog. Dell provides several online and telephone-based support and service options.
2 Hardware Installation Before using this guide, ensure that you review the instructions in the: • Dell PowerVault MD3460/MD3860i/MD3860f Storage Arrays Getting Started Guide — The Getting Started Guide that is shipped with the storage array provides information to configure the initial setup of the system.
• SAS host Expansion Ports (2) – Allows you to connect the storage array to optional PowerVault MD3060e expansion enclosures for additional storage capacity. Only one SAS OUT expansion port can be used at a time and the recommended expansion port is 0.
Other Information You May Need In addition to this document, see the documentation provided with the HBA and Fibre Channel switch hardware for vendor-specific information required to complete Fibre-Channel setup on your storage array.
Figure 1. Example of Switch Zoning on SAN on an MD38xxf-series Fibre-Channel Storage Array World Wide Name Zoning There are several different switch zoning techniques used across various SANs.
together, the switch allows the host server to see only devices included in that zone, decreasing the amount of time it would otherwise take for the host server to query attached, but out-of-zone, devices.
the host server(s) from losing access to data in the event of a path failure since both RAID controller modules can independently access all the physical disks in the storage array.

Power on all MD3060e expansion enclosures before you power on the array enclosure. For helpful videos and other resources on PowerVault MD series, see dell.
For more information, see the Support Matrix at dell.com/powervaultmanuals . 2. Install the software and driver package included on the PowerVault MD Series resource media. For information about installing the software, see Installing MD Storage Manager .
3 Installing MD Storage Manager The PowerVault MD Series resource media contains software and drivers for both Linux and Microsoft Windows operating systems. The root of the media contains a readme.txt file describing changes to the software, updates, fixes, patches, and other important data applicable to both Linux and Windows operating systems.
The PowerVault MD Series resource media offers the following installation methods: • Graphical Installation (Recommended) — This is the recommended installation procedure. The installer presents a graphical wizard-driven interface that allows customization of components installed.
8. Start MD Storage Manager and discover the array(s). NOTE: If Dynamic Host Configuration Protocol (DHCP) is not used on the network where the PowerVault MD storage array’s management ports are connected, it is recommended that you enable IPv6 on the management station to discover the storage array(s).
NOTE: On Red Hat Enterprise Linux 6 operating systems, run the following script from the root directory to install prerequisite packages: # md_prereq_install.sh 1. Copy the custom_silent.properties file in the /linux directory of the installation media or image to a writable location on the host server.
4 Post Installation Tasks Before using the Dell PowerVault storage array for the first time, complete these initial configuration tasks in the order shown.
• To add an array, in the EMW, select Automatic Discovery . NOTE: You can also add an array in the EMW using its known management ports IP addresses. Initial Setup Tasks 1. The name of the first storage array found is displayed in the Devices tab of the EMW.
5 Uninstalling MD Storage Manager Uninstalling MD Storage Manager From Windows To uninstall the Modular Disk Storage Manager from Microsoft Windows Server: 1. Double-click Add or Remove Programs from the Control Panel . 2. Select Dell MD Storage Software from the list of programs.
Uninstalling MD Storage Manager From Linux By default, PowerVault MD Storage Manager is installed in the /opt/dell/mdstoragemanager directory. If another directory was used during installation, navigate to that directory before beginning the uninstallation procedure.
6 Load Balancing Load Balance Policy Multi-path drivers select the I/O path to a virtual disk through a specific RAID controller module. When the multi-path driver receives a new I/O to process, the driver tries to find a path to the current RAID controller module that owns the virtual disk.
If more than one data path to the virtual disk has the same weight value, the round robin with subset path selection policy is used to route I/O requests between the paths with the same weight value. The least path weight load balance policy is not supported on Linux operating systems.
7 Appendix — Working With SFP Modules And Fiber Optic Cables Each storage controller can have up to four FC host ports. A small-form-factor pluggable (SFP) module is used to connect a host port to a host or switch. The SFP module is inserted into the port, and then a fiber optic cable is inserted into the SFP module.
5. Connect an FC cable. See Installing Fibre Channel Cables . Figure 7. Installing and Removing an SFP Module 1. FC IN slot (4) 2. SFP+ transceiver 3. fibre optic cable 4. gate Removing SFP Modules To remove SFP modules: 1. Remove the FC cable from the SFP module.
Installing Fibre Channel Cables WARNING: Data processing environments can contain equipment transmitting on system links with laser modules that operate at greater than Class 1 power levels. Never look into the end of an optical fiber cable or open receptacle.
8 Appendix — Hardware Cabling Best Practices Handling Static Sensitive Components Static electricity can damage memory modules, system boards, and other static-sensitive components. To prevent damaging the system, follow these precautions: • Move and store all components in the static-protective packaging.
Labeling Cables Cabling is an important part of creating a robust storage array. Labeling the cables identifies system components and drive channels. System maintenance is easier when the cables are correctly identified. Label both ends of each cable.
