1IntroductionThis document provides information about deploying Dell PowerVault MD3400 and Dell PowerVaultMD3420 storage arrays. The deployment process includes:• Hardware installation• Modular Disk Storage Manager (MDSM) software installation• Initial system configurationOther information includes system requirements, storage array organization, and utilities.NOTE: For more information on product documentation, see Related Documentation.MDSM enables an administrator to configure and monitor storage arrays for optimum usability. Theversion of MDSM included on the PowerVault MD series resource media can be used to manage both theDell PowerVault MD3400 and Dell PowerVault MD3420 systems and the earlier PowerVault MD seriesstorage arrays. MDSM is compatible with both Microsoft Windows and Linux operating systems.System RequirementsBefore installing and configuring the PowerVault MD3400 and MD3420 series hardware and software,ensure that the minimum system requirements are met, and the supported operating system is installed.For more information, see the Dell PowerVault MD34xx/38xx Series Support Matrix at dell.com/support/manuals.Management Station RequirementsA management station uses MDSM to configure and manage storage arrays across the network. Formanagement station requirements, see Dell PowerVault MD34xx/38xx Series Support Matrix at dell.com/support/manuals.Introduction to Storage ArraysA storage array includes various hardware components, such as physical disks, RAID controller modules,fans, and power supplies, gathered into enclosures. The physical disks are accessed through the RAIDcontroller modules.One or more host servers attached to the storage array can access the data on the storage array. You canalso establish multiple physical paths between the hosts and the storage array so that loss of any singlepath (for example, through failure of a host server port) does not result in loss of access to data on thestorage array.The storage array is managed by MDSM running on a:5
