  • Page 16: Cache Functions And Features

    Write Through for all virtual disks. When the battery is replaced, Write Back is reenabled. The RAID controller module logs the age of the battery and issues a replacement reminder message approximately six weeks before expiration. After replacing the battery, you must use MD Storage Manager to reset the battery age.

  • Page 17: Power Supply And Cooling Fan Features

    Write-Back Cache Write-back cache is a caching strategy whereby write operations result in a completion signal being sent to the host operating system as soon as the cache receives the data to be written. The target physical disk will receive the data at a more appropriate time in order to increase controller performance. In dual- active controller configurations with write-back caching enabled, the write data is always copied to the cache of the second controller before completion status is issued to the host initiator.

  • Page 20: Cabling The Enclosure

    RAID controller module results in loss of host access to storage on the RAID enclosure. Redundancy is established by installing separate data paths between the host and the storage array, in which each path is to different RAID controller modules. Redundancy protects the host from losing access to data in the event of path failure, because both RAID controllers can access all the disks in the storage array.

  • Page 22: Nonredundant Configurations

    Figure 2-3 through Figure 2-5 show two, three and four hosts, each connected to only one RAID controller module. The hosts can share storage space but without redundant paths, if one path were to fail, the server on that path would be disconnected from the storage array.

  • Page 27: Using Your Raid Enclosure

    255 virtual disks that can be assigned to hosts. Physical Disks Only Dell-supported 3.0-Gbps SAS physical disks are supported in the storage array. If the RAID controller module detects unsupported physical disks, it marks the disk as unsupported and the drive becomes unavailable for all operations.

  • Page 28: Self-Monitoring Analysis And Reporting Technology (Smart)

    The RAID controller monitors all attached drives and notifies users when a predicted failure is reported by a physical disk. Virtual Disks and Disk Groups When configuring a storage array, you would normally proceed in this order: • Organize the physical disks into disk groups.

  • Page 29: Supported Raid Levels

    Unconfigured capacity is comprised of the available physical disk space that is not already assigned in the storage array. Free capacity is the space in a disk group that has not been assigned to a virtual disk.

  • Page 30: Raid 5

    This leaves the remaining half of the physical disk capacity for actual storage. RAID 10 is automatically used when a RAID level of 1 is chosen with four or more physical disks.

  • Page 31: Segment Size

    128 KB. Hot Spares and Rebuild A valuable strategy to protect data is to assign available physical disks in the storage array as hot spares. A hot spare adds another level of fault tolerance to the storage array.

  • Page 32: Rebuild

    RAID software automatically attempts to rebuild the data to restore redundancy. If no hot spares are available, an automatic rebuild occurs when a new physical disk is installed. You can use MD Storage Manager to select a specific physical disk on which the rebuild should occur.

  • Page 33: Virtual Disk Operations

    NOTE: 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, since the system does not have the redundancy to recover the data.

  • Page 34: Disk Group Operations

    (RAID 0) by converting it to a RAID 5 set. Select the virtual disk that you want to change and select the type of RAID level to which you want to migrate. MD Storage Manager provides information about RAID attributes to assist you in selecting the appropriate level. You can perform a RAID level migration while the system is still running and without rebooting, which maintains data availability.
  • Page 35 (the segment size multiplied by the number of physical disks in the disk group used for data storage). In this case, multiple disks are used for the same request, but each disk is only accessed once. Virtual Disk Capacity Expansion When you configure a virtual disk, you select a capacity based on the amount of data you expect to store.

  • Page 36: Raid Background Operations Priority

    NOTE: Setting a high priority level will impact storage array performance. It is not advisable to set priority levels at the maximum level. Priority should also be assessed in terms of impact to host access and time to complete an operation.

  • Page 37: Advanced Features

    To create a storage partition, you first define a host or host group, then define a host-to-virtual disk mapping.

  • Page 38: Host Types

    Not every operating system will have the same number of LUNs available for use. Host Types Generally, a host is a server that accesses a storage array, is mapped to the virtual disks, and uses one or more HBA ports. In general, hosts have the following attributes: •...

  • Page 39: Snapshot Repository Virtual Disk

    When you create a snapshot virtual disk, it automatically creates a snapshot repository virtual disk. A snapshot repository is a virtual disk created in the storage array as a resource for a snapshot virtual disk. A snapshot repository virtual disk contains snapshot virtual disk metadata and copy-on-write data for a particular snapshot virtual disk.

  • Page 40: Using Snapshot And Disk Copy Together

    Using Snapshot and Disk Copy Together You can use the Snapshot Virtual Disk and Virtual Disk Copy premium features together to back up data on the same storage array, or to restore the data on the snapshot virtual disk to its original source virtual disk.

  • Page 41: Host Bus Adapters

    You can have multiple SAS HBA host ports-to-array connections for each host. When setting up host mapping, you must select the HBA host ports from the list of Known HBA host ports in MD Storage Manager. Add all of the HBA host ports to the list of Selected HBA host port identifiers/aliases for the host for which you are defining the LUN mapping.

  • Page 42: Host Cabling For Redundancy

    Host Cabling for Redundancy To make sure that the RAID storage array will remain accessible to the host, establish a minimum of two physical paths from each host to the RAID controller modules. The following examples show host cabling for redundancy.
  • Page 43 Figure 3-2. One Host with Four Cable Connections RAID controller module 0 This cabling topology, when used with alternate path software, ensures a redundant path from the host to the virtual disks. If any component (HBA, HBA port, cable, RAID controller module port, or RAID controller module) fails, the host can still access the virtual disks through an alternate path.

  • Page 44: When A Raid Controller Module Is Replaced Or Removed

    • Controller-based Auto Virtual Disk Transfer (AVT) Host-based uses a multi-path driver installed on the host server to access the storage array. If required, the multi-path driver will issue an explicit command to transfer ownership from the RAID controller module that owns the virtual disk to its peer RAID controller module.

  • Page 45: Raid Enclosure Thermal Shutdown

    RAID controller module while the other RAID controller module's firmware is upgraded. Also check the MD Storage Manager to see if it lists both RAID controller modules as optimal. Downloading firmware when either or both controllers are non-optimal may result in unsynchronized firmware and cause you to have to run the download again after restoring the RAID controller module(s) to optimal condition.

  • Page 46: Physical Disk Firmware

    Physical Disk Firmware NOTE: Dell recommends stopping all I/O to the array when downloading physical disk firmware. 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.
