Introduction

This guide provides information about deploying Dell PowerVault MD3860f storage arrays. The deployment process includes:

• Hardware installation

• Modular Disk Storage Manager (MD Storage Manager) installation

• Initial system configuration

Other information provided include system requirements, storage array organization, and utilities.

NOTE: For more information on product documentation, see Related Documentation.

MD Storage Manager enables an administrator to configure and monitor storage arrays for optimum usability. The version of MD Storage Manager included on the PowerVault MD Series resource media can be used to manage both the PowerVault MD3860f Series and other PowerVault MD Series storage arrays. MD Storage Manager is compatible with both Microsoft Windows and Linux operating systems.

System Requirements

Before installing and configuring the PowerVault MD3860f Series hardware and software, ensure that the supported operating system is installed and minimum system requirements are met. For more information, see the Support Matrix at dell.com/powervaultmanuals.

Management Station Requirements

A management station uses MD Storage Manager to configure and manage storage arrays across the network. For more information on management station requirements, see the Support Matrix at

dell.com/powervaultmanuals.

Introduction To Storage Arrays

An enclosure containing physical disks accessed through RAID controller modules is called a storage array. A storage array includes various hardware components, such as physical disks, RAID controller modules, fans, and power supplies.

One or more host servers attached to the storage array can access the data on the storage array. You can also establish multiple physical paths between the host(s) and the storage array so that loss of any single path (for example, through failure of a host server port) does not result in loss of access to data on the storage array.

The storage array is managed by MD Storage Manager running on a:

• 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.

• Management station — On a management station, MD Storage Manager communicates with the

storage array either through an Ethernet connection to the storage array management port or

through an Ethernet connection to a host server. The Ethernet connection passes management

information between the management station and the storage array using array connectivity.

Using MD Storage Manager, you can configure the physical disks in the storage array into logical components called disk groups and Dynamic Disk Pool (DDP), then divide the disk groups into virtual disks. Disk groups are created in the unconfigured capacity of a storage array. Virtual disks are created in the free capacity of a disk group.

Unconfigured capacity comprises physical disks not already assigned to a disk group or DDP. When a virtual disk is created using unconfigured capacity, a disk group is automatically created. If the only virtual disk in a disk group is deleted, the disk group is also deleted. Free capacity is space in a disk group that is not assigned to any virtual disk.

Data is written to the physical disks in the storage array using RAID technology. RAID levels define the way in which data is written to physical disks. Different RAID levels offer different levels of accessibility, redundancy, and capacity. You can set a specified RAID level for each disk group and virtual disk on your storage array. For more information about using RAID and managing data in your storage solution, see the Dell PowerVault MD Series Storage Arrays Administrator's Guide at dell.com/powervaultmanuals.

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.

• Dell PowerVault MD Series Storage Arrays Administrator's Guide — The Administrator's Guide provides

information about important concepts you must know before setting up your storage solution. For

more information, see dell.com/powervaultmanuals.

• The Rack Installation instructions — Provides information on how to rack your system. This document

is shipped with your system.

Planning The Storage Configuration

Consider the following before installing your storage array:

• Evaluate data storage needs and administrative requirements.

• Calculate availability requirements.

• Decide the frequency and level of backups, such as weekly full backups with daily partial backups.

• Consider storage array options, such as password protection and e-mail alert notifications for error

conditions.

• Design the configuration of virtual disks, disk groups, and DDP according to a data organization plan.

For example, use one virtual disk for inventory, a second for financial and tax information, and a third

for customer information.

• Decide whether to allow space for hot spares, which automatically replace failed physical disks.

Connecting The Storage Array

The storage array is connected to a host using two hot-swappable RAID controller modules. The RAID controller modules are identified as RAID controller module 0 and RAID controller module 1. The ports on the RAID controller module and their functions are listed below:

• 16 Gbps Fibre channel Host Ports (4) – Provides FC connection to the host or node.

NOTE: When you connect a host server to a storage array FC IN port connector, any OUT port connector of the host bus adapter (HBA) of the server can be used.

• 1 Gbps Ethernet Management (MGMT) Port (1) – Management port allows for out-of-band

management of storage array.

• Reserved Ethernet Port (1) – Reserved port.

• 12 Gbps SAS host Ports (2) – Additional SAS Host ports.

• 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.

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. For basic setup information such as racking, power cabling, and recommended handling procedures, see the Getting Started Guide for your Storage Array at dell.com/

powervaultmanuals.

Configuring Fibre Channel On SAN Attached Storage Arrays

You can only cable the host server to the storage array via storage area network (SAN) using supported Fibre Channel switch(es).

NOTE: For detailed information on supported Fibre Channel hardware, see the Support Matrix at dell.com/powervaultmanuals.

The following steps shows the configuration order for connecting to a SAN. These steps assume you are setting up Fibre Channel storage for the first time.

NOTE: If you are adding an additional Fibre Channel storage array or if your host server is already configured to access Fibre Channel storage, some of the steps may not apply. Before proceeding, see the Dell PowerVault MD Series Support Matrix to confirm that your existing hardware components and host bus adapter (HBA) firmware and BIOS levels are supported.

Configuring Fibre Channel

To configure a Fibre Channel for connecting to a SAN:

1. Install the supported HBAs on your host server.

2. Cable the host server to the Fibre Channel switches.

For more information, see SAN-Attached Cabling Example and Remote Replication Cabling

Example.

3. Install the required HBA drivers and firmware versions listed in the Dell PowerVault MD Series

Support Matrix available at dell.com/powervaultmanuals.

4. Install and configure the MD Storage Manager software (included with your storage array) on your

host server.

5. Cable the storage array to the Fibre Channel switches.

6. Configure zoning on all Fibre Channel switches.

For more information, see Switch Zoning Guidelines.

7. Using MDSM, configure the host servers, storage arrays, and virtual disks.

8. Activate and configure premium features (if applicable).

NOTE: All equipment attached to the switch must be powered on before establishing zoning. For additional switch hardware requirements, see the manufacturer’s documentation.

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.

Installing Supported Fibre Channel HBAs

The storage array supports a specific set of Fibre Channel HBAs, each requiring a unique driver and firmware level. See the Dell PowerVault MD Series Support Matrix at dell.com/powervaultmanuals for a list of supported HBAs.

If an HBA is already installed on your host server, verify that it is supported in the Dell PowerVault MD Series Support Matrix. If the HBA is not listed, it should not be used to connect to the storage array.

CAUTION: Connecting the storage array to a non-supported host server HBA or installing nonqualified HBA drivers or firmware can cause instability or loss of access to your data.

Installing Fibre Channel HBA On Your Host Server

For instructions about physically installing an HBA in your host server and loading supported drivers and firmware, see the documentation supplied with your HBA hardware.

NOTE: During installation you must enter the manufacturer-specific timeout and/or node time values. See the Dell PowerVault MD Series Support Matrix at dell.com/powervaultmanuals for information related to your specific HBA.

Using Fibre Channel Switch Zoning

A Fibre Channel switch allows you to connect multiple devices to the SAN without compromising bandwidth or data throughput. Switch zoning implemented on each Fibre Channel switch hardware component using the manufacturer’s embedded utility, allows you to divide port traffic between the host server and storage array to maintain the highest level of redundancy.

The following figure shows each connection to the host server(s) routed to an individual logical zone on the SAN. Two physical switches provide an alternate (redundant) data path to the storage array. If a single HBA, switch or RAID controller fails, the host server(s) can still access data on the storage array through one of the alternate paths provided by the switches.

NOTE: For a list of supported Fibre Channel switches, see the Dell PowerVault MD Series Support Matrix at dell.com/powervaultmanuals.

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. When configuring zoning with your storage array, using a 64 bit World Wide Name (WWN) to uniquely identify each component in your Fibre Channel switch fabric is recommended. An advantage of using WWN port zoning (also called soft zoning) is that it allows you to remove and/or replace cabling to and from the fabric without reconfiguring the existing zone logic.

When implemented on the Fibre Channel switch, port WWN zoning causes the host server to query the World Wide Identifier (WWID) name of all attached physical disks and/or expansion enclosures each time it accesses the switch fabric. By zoning specific ports on the host server(s), switch and storage array
