Figure 1. Comparison of Dell PowerVault MD1000 and PowerVault MD3000 storage

Disk Storage Manager graphical user interface (GUI) or command-line interface (CLI). The GUI includes wizard-based tools and a task-based structure designed to simplify installation, con- figuration, management, and diagnostic tasks. Modular Disk Storage Manager enables admin- istrators to discover storage systems through either Serial Attached SCSI (SAS) or Ethernet, troubleshoot using diagnostic utilities, and manage virtual disks, hot-spare drives, firm- ware upgrades, and event logs (see Figure 4). It includes both in-band and out-of-band man- agement capabilities, along with an optional event monitoring service (used to send alerts when a critical problem occurs).

In-band management is available when the PowerVault MD3000 is connected to the host server using SAS and Modular Disk Storage Manager is fully installed, including the host- based storage agent, multipath drivers, and management station package. Out-of-band man- agement is available when client systems can connect to the PowerVault MD3000 using Ethernet and the Modular Disk Storage Manager management station package is installed.

Figure 2). The Automatic Virtual Disk Transfer feature of Dell Modular DiskStorage Manager provides failover and is designed specifi- cally for single-port cluster failover; it is automatically selected by host type during host access configuration.

Dual port: Administrators can use this mode with dual storage paths and with dual-port RAID controllers (see Figure 3, which shows a configuration utilizing two HBAs on each

host server). Multipath drivers such as MPIO and MPP are installed on host servers and provide I/O path failover. The controller firmware executes ownership transfer oper- ations for virtual disks and owns the logical units (LUNs).

Management and monitoring features Administrators can manage and monitor the PowerVault MD3000 using the Dell Modular

The Modular Disk Storage Manager CLI gives administrators direct access to a script engine utility that reads commands and runs script files. Tasks administrators can perform using the CLI include the following:

Create script command batch files when installing the same configuration on multi- ple storage arrays

Run script commands on a storage array directly connected to a host, a storage array
