1 Introduction This document provides information about deploying Dell PowerVault MD3800f and MD3820f Fibre Channel storage arrays. The deployment process includes: • Hardware installation • Modul.
• Host server — On a host server system, MDSM and the storage array communicate management requests and event information using in-band or out-of band-connections.
Contacting Dell Dell provides several online and telephone-based support and service options. If you do not have an active Internet connection, you can find contact information on your purchase invoice, packing slip, bill, or Dell product catalog. Availability varies by country and product, and some services may not be available in your area.
2 Hardware Installation Before using this guide, ensure that you review the instructions in the documents: • Getting Started Guide — The Getting Started Guide shipped with the storage array provides information to configure the initial setup of the system.
Each PowerVault MD3800f and MD3820f series storage array can be expanded to a maximum of 120 (or 192, if enabled using Premium Feature activation) physical slots. Configuring Fibre Channel With Dell MD Series Storage Arrays This section provides information about configuring Fibre Channel communication between the host server and the storage array.
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.

Figure 4. Mixed Environment Cabling PowerVault MD1200 Series Expansion Enclosures You can expand the capacity of your PowerVault MD3800i and MD3820i series storage array by adding PowerVault MD1200 series expansion enclosures.
CAUTION: If a PowerVault MD1200 series expansion enclosure that was previously attached to PERC H800 adapter is used as an expansion enclosure to a PowerVault MD34xx/MD38xx series storage array, the physical disks of the expansion enclosure are reinitialized and data is lost.
b. Set up the PowerVault MD1200 series expansion enclosures. For information about setting up the PowerVault MD1200 series expansion enclosures, see the Owner’s Manual at dell.com/support/ manuals . c. Using MDSM, update the RAID controller module firmware and NVSRAM to the latest versions available on dell.
3 Installing PowerVault MD Storage Software The Dell PowerVault MD series resource media contains software and drivers for both Linux and Microsoft Windows operating systems.
Installing Host Bus Adapters and Drivers Ensure that you read the Configuring Fibre Channel With the Dell PowerVault MD Series Storage Arrays document before continuing with this procedure. 1. Install the host bus adapters (HBAs). 2. Connect the cables.
Console Installation NOTE: Console installation only applies to Linux systems that are not running a graphical environment. The autorun script in the root of the resource media detects when there is no graphical environment running and automatically starts the installer in a text-based mode.
Upgrading MD Storage Software To upgrade from a previous version of the MDSM application, uninstall the previous version (see Uninstalling MD Storage Software ), and then follow the instructions in this chapter to install the new version.
4 Post Installation Tasks Before using the Dell PowerVault storage array for the first time, complete these initial configuration tasks in the order shown.
4. If the array still shows an Unresponsive status, contact Dell. Initial Setup Tasks Enter the context of your task here (optional). This is where introductory content goes. 1. The name of the first storage array found is displayed in the Devices tab of the EMW.
5 Uninstalling MD Storage Software Uninstalling MD Storage Software From Windows 1. From the Control Panel, double-click Add or Remove Programs . 2. Select MD Storage Software from the list of programs. 3. Click Change/Remove . The Uninstall Complete window is displayed.
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 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.
3. With the SFP+ module latch in the unlocked position, remove the SFP+ module. For SFP+ modules that contain wire tabs, grasp the wire latch and pull the SFP+ module out of the port. 4. Replace the protective cap on the SFP+ module and the host port.
Before installing an FC cable, see Guidelines for Using Fiber Optic Cables . 1. If applicable, remove the protective cap from the SFP+ module and store the protective cap for future use. 2. Remove the two protective caps from one end of the cable and store them for future use.
8 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.
Single-Controller and Dual-Controller Topologies While creating a topology for a RAID enclosure that contains only one RAID controller module, attach expansion enclosures that contain only one single environmental services monitor (ESM). Do not attach an expansion enclosure that contains two ESMs to a single-controller RAID enclosure.
