Removing and Installing an EMM

An enclosure with redundant enclosure management contains two EMMs and can be configured in either a unified mode or split mode. An enclosure with nonredundant enclosure management consists of one EMM configured in unified mode.

If only one EMM is installed in your enclosure, the empty slot must contain a blank cover. The blank cover ensures that the enclosure has the proper cooling airflow to prevent overheating. For information on installing the blank cover, see "Installing an EMM Module Cover in an Empty Bay."

NOTICE: EMMs can be removed and installed without shutting down the enclosure. However, removing an EMM while data traffic is occurring that involves that EMM could cause data loss and is not recommended. Replacing or reinserting an EMM that is connected to a host will cause the host to lose communication with the enclosure and will require a reboot of the host server. For more information, see "Troubleshooting a Loss of Communication Condition."

NOTICE: To prevent damage to your enclosure, you should wear a wrist grounding strap while performing the following procedures. See your Product Information Guide for safety information.

Removing an EMM

NOTICE: If you remove an EMM from an enclosure operating in split mode while connected to a host server, you will lose connection to the drives attached to the removed EMM.

1Push up on the release tab on the left side of the module (see Figure 3-5).

2At the same time, pull out on the release lever. When the lever is pulled out, the EMM partially ejects from the enclosure.

3Remove the module from the enclosure and place it on a flat, secure surface.

NOTE: To avoid damage to the sensitive EMI contacts on the bottom of the EMM, do not stack EMMs or place them on a hard surface.

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.
