Failed Virtual Disks

NOTE: This warning message appears if one or more virtual disk(s) are spanned across two or more enclosures or if an enclosure in split mode is shared by one server.

1During POST, press <Ctrl><R> to enter the Ctrl-R utility.

2Find the virtual disk(s) marked as Failed and record all settings from the Properties screen, including RAID level, physical disk members, physical disk order (sequence), virtual disk size, and stripe (element) size.

3Delete the failed virtual disk.

4Clear the remaining foreign configuration.

5Re-create the original virtual disk using the original set of disk drives, and the identical parameters recorded in step 2. This re-establishes the configuration information.

NOTE: Do not initialize the new virtual disks.

6Exit the Ctrl-R utility and boot to the operating system.

For more information on the Ctrl-R utility, see the Dell PERC5/E Adapter User’s Guide.

Troubleshooting External Connections

Loose or improperly connected cables and bent pins are the most likely source of problems. Ensure that all external cables are securely attached to the external connectors on your system and that none of the connectors are damaged. See "Back-Panel Indicators and Features" for the back-panel connectors on your enclosure.

Troubleshooting a Wet Enclosure

Problem

Liquid spilled on the enclosure.

Excessive humidity.

Action

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.
