Copy SAN LUN, Data Protection Tab, Auto Tier

Navigation: SAN > Storage > LUNs > Actions > Copy > Data Protection > Auto Tier

Adds data protection schedules to LUN copies. You can also manage data replication schedules from this page.

Storage Domain Capacity

Displays the storage capacity of the selected storage class and Storage Domain that is available for the logical volume. The graph uses colored bars of different thicknesses to indicate the capacity status of the logical volume you are creating as well as the overall system capacity.

Capacity for Clone Storage

Enable Clones

Specifies whether to enable the Capacity for Clones options. Selecting this option also enables the Specify Clone QoS options.

Maximum capacity

Specifies the percentage of storage space to allocate for Clone LUNs.

Note: Changes to this field updates the Maximum and Available Capacity values. The capacity values are based on the Addressable Logical Capacity value that you provided in the Quality of Service tab.
Current Maximum Capacity

Identifies the maximum capacity to which the logical volume can grow. For a clone, this field identifies how much addressable space is available. Capacity must be greater than or equal to the allocated logical capacity.

Current Available Capacity

Identifies the amount of current storage capacity allocated for clones of this LUN.

Estimated Maximum Capacity

Specifies the estimated storage space to allocate for Clone LUNs. The value of this field changes as the Maximum Capacity percentage changes and as the Capacity value changes that you provided in the Quality of Service tab.

Estimated Available Capacity

Identifies the estimated available capacity for Clone LUNs. The value of this field changes as the Maximum Capacity percentage changes and as the Capacity value changes that you provided in the Quality of Service tab.

Clone Storage QoS

Match Repository QoS to LUN QoS

Specifies whether to apply the clone storage QoS properties using a Data Protection schedule, or manually applied by the administrator.

Specifies the enhanced QoS settings to apply to the clone storage that are created by the data protection schedule, or manually created by the administrator.

Initial Storage Class

Specifies the initial category of physical media on which the logical volume resides. For auto‑tiered LUNs, the Oracle FS System determines the actual Storage Class that matches the data usage statistics on the volume to get the most optimal performance.

Valid media types:
Performance SSD

Specifies that the data is stored on solid state drives (SSDs) that are optimized for the performance of balanced read and write operations.

Capacity SSD

Specifies that the data is stored on SSDs that are optimized for the performance of capacity and for read operations. The write performance for this Storage Class is sacrificed somewhat to achieve the optimizations for read performance and for capacity.

Performance Disk

Specifies that the data is stored on high-speed hard disk drives (HDDs). This Storage Class sacrifices some capacity to reduce the access time and the latency of the read operations and of the write operations.

Capacity Disk

Specifies that the data is stored on high-capacity, rotating HDDs. This Storage Class optimizes capacity at some sacrifice of speed. For a storage system that does not include tape storage as an option, this Storage Class always provides the lowest cost for each GB of capacity.

Basic
Allows you to specify indirectly the parity level of the data and the read-ahead policy for the data. You specify those properties indirectly by selecting how the data is typically accessed and the level of data protection that is desired.
Note: After you select how the data is typically accessed and the level of redundancy for the data, the system displays the parity level and the read-ahead policy for the volume that supports your selections.
Initial Typical Access
Identifies the most common method of data access. Valid biases:
Sequential

Indicates that the read requests and the write requests operate on the data mostly by accessing the records one after the other in a physical order.

Random

Indicates that the read requests and the write requests operate on the data mostly by accessing the records in an arbitrary order.

Mixed

Indicates that the read requests and the write requests operate on the data sometimes in sequential order and sometimes in random order.

Initial I/O Bias
Identifies the typical read‑write ratio. Valid I/O biases:
Read

Indicates that most of the access requests are for read operations.

Write

Indicates that most of the access requests are for write operations.

Mixed

Indicates that the number of access requests are similar for read operations and for write operations.

Advanced
Allows you to specify directly the parity level of the data and the read-ahead policy for the data.
Important! Use of this option clears the selections, if any, that were made in the Basic option.
Initial RAID Level

Identifies the initial RAID level associated with the Storage Profile. The Oracle FS System determines the actual RAID Level that matches the data usage statistics on the volume to get the most optimal performance.

Possible RAID levels:
Single parity

Indicates that, in addition to the actual data, one set of parity bits exists for the logical volume. This parity level protects against the loss of one drive. Single parity is implemented as a variant of the RAID 5 storage technology.

Double parity

Indicates that, in addition to the actual data, two sets of parity bits exist for the logical volume. This parity level protects against the loss of one or two drives with a slight cost to write performance. Double parity is implemented as a variant of the RAID 6 storage technology.

Mirrored

Indicates that no parity bits exist for the volume. Instead, the system writes the data in two different locations. This RAID level protects against the loss of at least one drive and possibly more drives with an improvement of the performance of random write operations. Mirrored RAID is implemented as a variant of the RAID 10 storage technology.

Priority Level
Identifies the priority that the system gives to various operational aspects of a logical volume. These operational aspects include the Controller processing queue, the SAN interface requests, and the migration of the auto-tiered LUN extents.
Note: The processing-queue priority defines the percentage of the Controller CPU cycles that are dedicated to the volume.
Premium

Indicates the highest priority for responding to requests in the processing queue. For auto-tiered LUNs, busy LUN extents receive the highest priority when the system migrates the data to the higher-performing storage tiers.

High

Indicates the next highest priority for responding to requests in the processing queue. For auto-tiered LUNs, busy LUN extents receive the next highest priority when the system migrates the data to the higher-performing storage tiers.

Medium

Indicates an intermediate priority for responding to requests in the processing queue. For auto-tiered LUNs, busy LUN extents receive an intermediate priority when the system migrates the data to the higher-performing storage tiers.

Low

Indicates the next to lowest priority for responding to requests in the processing queue. For auto-tiered LUNs, busy LUN extents receive the next to lowest priority when the system migrates the data to the higher-performing storage tiers.

Archive

Indicates the lowest priority for responding to requests in the processing queue. For auto-tiered LUNs, busy LUN extents receive the lowest priority when the system migrates the data to the higher-performing storage tiers.

Additional Options

Displays a dialog that allows you to select Auto Tier Storage Class options.

Clone Schedules

Lists the data protection schedules that are associated with the logical volume.

Name

Identifies the name of the schedule.

Start Time

Identifies the date and time that the schedule begins.

Frequency
Identifies the frequency at which the schedule runs. Frequencies include:
  • Run Once
  • Hourly
  • Daily
  • Weekly
Enabled
Identifies whether the schedule is enabled.
Enabled

Indicates that the scheduled operation performs at the specified time.

Disabled

Indicates that the operation is not performed as scheduled. Disable the schedule, for example, when the source volume (LUN or Clone LUN) has not been made available to users.

Create

Displays a dialog to create a scheduled operation.

Modify

Displays a dialog to modify an existing schedule.

Delete

Removes an existing schedule.
