6Turn off the MD3000 enclosure.

7Connect the MD1000 expansion enclosure(s) to the MD3000 enclosure, as shown in the Dell PowerVault Compatibility Matrix (available from support.dell.com).

8Power on the systems in the following order:

a Turn on the MD1000 expansion enclosure or enclosures. Wait for the enclosure status LED to turn blue.

b Turn on the MD3000 enclosure and wait for the status LED to indicate that the unit is ready:

If the status LED is solid amber, the MD3000 is still coming online.

If the status LED is blinking amber, there is an error that can be viewed using the MD Storage Manager.

If the status LED is solid blue, the MD3000 enclosure is ready.

cAfter the MD3000 enclosure is online and ready, turn on any attached hosts.

NOTICE: If an MD1000 or MD3000 status LED is either blinking or solid amber, follow the troubleshooting steps in the MD Storage Manager.

Changing Your Enclosure’s Operating Mode

If you decide to change the operating mode of your enclosure after initial configuration (for example, from split mode to unified mode or vice versa), it is important to follow some basic steps to guard against preventable problems.

To change to either mode from a previous configuration:

1Back up all data contained in the enclosure and store the backed up data in a secure location.

2When changing from unified mode to split mode, remove any virtual disk configurations that span slot ranges 0-6 and 7-14. For more information, see your Server Administrator documentation.

NOTE: When changing from split mode to unified mode, some virtual disks may appear as foreign if the configuration was not deleted before powering the enclosure back on. These disks must be imported via Server Administrator or the PERC 5/E Ctrl-R BIOS utility before they can be used.

NOTE: If changing from unified mode to split mode, keep in mind that daisy chaining of enclosures is not supported in split mode.

3Power down the server.

4Power down the enclosure by turning off both power supply/cooling fan modules.

5Change the position of the enclosure mode switch (see Figure 1-7).

6Rearrange the disks in the enclosure as necessary.

7Power on the enclosure by turning on both power supply/cooling fan modules.

8Power on the server.

9Re-create any virtual disks within the enclosure, if necessary.

MD1000 specifications

The Dell MD1000 is a storage enclosure designed to provide a scalable and reliable solution for enterprises seeking efficient data storage management. Recognized for its robust performance and versatility, the MD1000 supports a variety of applications, making it a popular choice among organizations that demand high-capacity storage solutions.

One of the standout features of the MD1000 is its modular design, allowing it to integrate seamlessly with various Dell server systems. It provides efficient data storage through its 3.5-inch drive bays, accommodating up to 15 hard drives or solid-state drives. This configuration not only facilitates higher storage density but also supports SATA and SAS drives, offering the flexibility to choose different types of storage media based on organizational needs.

The MD1000 features advanced RAID (Redundant Array of Independent Disks) technology, which enhances data protection and system performance. It supports multiple RAID levels, including RAID 0, 1, 5, 6, and 10, providing users with different options for balancing performance and redundancy. By leveraging RAID, the MD1000 ensures that data remains safe and accessible even in the event of hardware failure, significantly reducing downtime and risk.

Connectivity is another strength of the MD1000. It typically interfaces with a server through a variety of host interface options including iSCSI and Fibre Channel, making it adaptable to different network configurations. This connectivity flexibility supports various environments, ensuring organizations can scale their storage without significant infrastructure overhauls.

Cooling and power efficiency are also critical characteristics of the MD1000. It includes dual-redundant power supplies and cooling fans that not only enhance reliability but also lower operational costs. These components can function independently, ensuring that power loss in one does not affect overall system performance.

Management and monitoring capabilities of the MD1000 are empowered by the Dell OpenManage software, which provides a user-friendly interface to manage the storage subsystem. Users can easily monitor drive health, configure RAID settings, and receive alerts on potential issues, simplifying the administration of large storage networks.

Overall, the Dell MD1000 is built to accommodate growing storage needs while ensuring reliability, performance, and ease of use. With its modular design, support for various drive types, robust RAID capabilities, versatile connectivity options, and efficient power management, it represents an excellent choice for businesses looking to enhance their data storage infrastructure.
