The RAID enclosure can be daisy-chained with up to two additional MD expansion enclosures, providing access to a maximum of 45 disks in the entire storage array.

Getting Started With Your System provides an overview of enclosure features, setting up your enclosure, and technical specifications. Always check for updates on support.

This port allows you the option to connect the RAID enclosure to an expansion enclosure. Refer to the PowerVault MDi Installation Guide for details and illustrated examples of how to configure your storage array. Power is on and enclosure status is OK.

Back-Panel Indicators and Features Figure shows the back-panel features of the enclosure. Link is operating at Mbps.

Battery backup unit or battery has amber. LED green Mbps. Ethernet connection is operating at 10 Mbps or is not active. Debug Port Dell support only. Between 1—3 links are connected. All four links are connected. All links are down. The RAID controller firmware performs a test of the BBU at startup and will illuminate the battery fault LED if the battery is not operating within specified ranges, or if the battery is missing.

Cache Functions and Features Powercault Mirroring The cache mirroring function copies accepted host-write data from the primary controller to the partner controller.

This action ensures that host- write data is safely mirrored to the partner controller before successful completion status is returned to the host. If a controller fails, maual surviving controller safely retains all mirrored data. DC output mxnual are within specifications. No power or voltages not within specifications.

Number LUN that is recognized by the host operating system. Physical Disks Only Dell-supported 3. If the RAID controller module detects unsupported physical disks, it marks the disk as unsupported and the physical disk becomes unavailable for all operations.

Virtual Disks and Disk Groups When configuring a storage array, you would normally proceed in this order: Different RAID levels provide different levels of accessibility, redundancy, and powervautl. Using multiple physical disks manjal several advantages over using a single physical disk, including: RAID 5 RAID 5 uses parity and striping data across all physical disks distributed parity to provide high data throughput and data redundancy, especially for small random access.

Segment Size Disk striping enables data to be written across multiple physical disks. Disk striping enhances performance because striped disks are accessed simultaneously. Powervvault segment size or stripe element size specifies the size of data in a stripe written to a single disk.


The MDi supports stripe element sizes of 8, 16, 32, 64, and KB. By default, the RAID controller module automatically configures the number and type of hot spares based on the number and capacity of physical disks in your system.


A hot spare may have the following states: Other conditions under which sectors are added to the unreadable sector log include: Dell recommends that you run data consistency checks on a redundant array at least once a month. This allows detection and automatic replacement of unreadable sectors. Finding an unreadable sector during a rebuild of a failed physical disk is a serious problem, because the system does not have the redundancy to recover the data. The RAID controller module tracks the cycle for each disk group independent of other disk groups on the controller and creates a checkpoint.

If the media verification operation on a disk group is preempted or blocked by another operation on the disk group, the firmware resumes after the current cycle.

If the media verification process on a disk group is stopped due to a RAID controller module restart, the firmware resumes the process from the last checkpoint. Dynamic segment size migration enables the segment size of a given virtual disk to be changed. A default segment size was set when the virtual disk was created, based on such factors as the RAID level and expected usage. You can change the default value if actual usage does not match your needs. Disk Group Defragmentation Defragmenting consolidates the free capacity in the disk group into one contiguous area.

Defragmentation does not change the way in which the data is stored on the virtual disks. Disk Group Operations Limit The maximum number of active, concurrent disk group processes per controller is one. Only disk groups and associated virtual disks with all member physical disks present can be migrated from one storage array to another. Dell recommends that you only migrate disk groups that have all their associated member virtual disks in an optimal state.

Use either of the following methods to move disk groups and virtual disks: If a disk group is migrated from a storage array that has a premium feature enabled and the destination array does not have this feature enabled, an Out of Compliance error message can be generated.

Storage partitions give multiple host servers or host groups access to the same host server-to-virtual disk mappings. With these mappings, you can control which host server or host group may have access to a virtual disk in your storage array. The first time you map a virtual disk to a specific host server or host group, a storage partition is created.

You can manually configure powervaukt host server-to-virtual disk mapping. When you configure host server-to-virtual disk mapping, consider these guidelines: This, in turn, can result in data loss or an inaccessible snapshot. Microsoft VDS is a set of application programming interfaces APIs that provides a single interface for managing disks and other storage hardware, including creating volumes on those disks.

Virtual Disk Recovery You can use the Edit host server-to-virtual disk mappings feature to recover data from the backup del, disk.

This functionality enables you to unmap the original source virtual disk from its host server, then map the backup virtual disk to the same host server. The best practice for ensuring data access is to avoid a configuration with a single point of failure. A single point of failure is any component or path that is not duplicated redundant or whose failure can cause loss of data access. Redundancy and Non-Redundancy Redundancy means that a storage array has duplicate components, or alternate ways to provide essential services.

Mmd3000i and Alternate Controllers and Paths A preferred controller is a RAID controller module designated as the owner of a virtual disk or disk group. The preferred controller is automatically selected by MD Storage Manager when a virtual disk is created. You can change the preferred RAID controller module owner of a virtual disk after it is created.


Clustering requires simultaneous access from cluster nodes to shared storage. If you have clustering software installed on the host server, automatic failback should be disabled to prevent “ping-pong” with single-path failure. For more information on clustering, a link to clustering documentation is included on the MDi Resource CD under Product Documentation. Thermal Shutdown Enclosure management provides a feature which automatically shuts down the enclosure when the temperature within the RAID enclosure reaches dangerous extremes.

Thermal shutdown protects the data on the physical disks from corruption in the event of a manuap system failure.

The temperature at which shutdown occurs is determined by the enclosure temperature probe’s Nominal Failure Threshold and the Maximum Failure Threshold. You can also download physical disk packages containing the latest firmware files.

Ensure that the firmware files you select are compatible with the physical disks. Installing Enclosure Components This section explains how to install the following components: To avoid data loss when removing a physical disk, Dell recommends that you verify with MD Storage Manager that the appropriate disk is being removed.

Removing an Assigned physical disk could result in data loss. To ensure proper airflow for enclosure cooling, each slot should contain either an active physical disk or a disk blank.

Installing a SAS Physical Disk in the Carrier screws 4 physical disk carrier physical disk 2 With the physical disk carrier handle open, carefully align the channel on the disk carrier guide rail with the appropriate disk slot keying feature on the chassis face plate, and insert the disk see Figure The status LED indicator see Table for manuwl will display a steady green if powrvault physical disk is inserted properly. The battery unit is mounted inside the RAID controller module and connects to the controller circuit board.

This section describes how to remove and replace the battery unit. While the enclosure can operate temporarily with only one functional power supply, both cooling modules with two fans each must be present for proper cooling.

Use both hands when removing. The power supply is seated when its front plate is even with the front plate of the adjacent power supply. If the enclosure is powered on, the manuwl fault indicator see Figure remains illuminated until you connect the AC power cable to the Removing and Replacing the Control Panel faceplate screws 16 control panel thumbscrews manal Using a Torx T10 driver, remove all 16 screws from the front faceplate of the enclosure as shown in Figure Also, make sure the guide md3000l on the control panel is fully inserted into the mounting slot on the backplane.

While working inside the enclosure, do not attempt to perform service except as explained in this guide and elsewhere in your documentation. 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” Only trained service technicians are authorized to remove the enclosure cover and access any of the components inside the enclosure.
