This will create an FTV.

The items which can be specified during creation of an FTV are as follows.

Item

Specification

Explanation

Tier Pool Name

Required

This is the name of the Tier pool in which the FTV will be created.

FTV Name

Optional

This is the name of the FTV.

Total Capacity

Required

This is the capacity of the volume that will be created.

Volume Number

Required

This is the number of volumes that will be created.

Caution Threshold of FTV

Optional

This is the threshold of the ratio of the usage capacity at which caution is notified.

  • For ETERNUS DX100 S3/DX200 S3, DX500 S3/DX600 S3:

    Specify a threshold (%) at which a caution will be sent when the ratio of the physically assigned capacity in relation to the total capacity of the FTV exceeds this threshold.

  • For ETERNUS Disk storage systems other than those listed above:

    Specify a threshold (%) at which a caution will be sent when the ratio of the available capacity of the pool in relation to the remaining physically available capacity exceeds this threshold.

Priority FTSP

Optional

Select the sub-pool used when new allocation is required. If space is not available another sub-pool will be used.

Low Quota Share

Optional

This is the share to be assigned to the Low sub-pool upon relocation. (*1, *2)

Middle Quota Share

Optional

This is the share to be assigned to the Middle sub-pool upon relocation. (*1, *2)

High Quota Share

Optional

This is the share to be assigned to the High sub-pool upon relocation. (*1, *2)

Target Response Time
(*3)

Optional

This is the target value of the response time of the volume the user will be using.

*1: When Tiering policy is not set to the Tier pool where FTV is made, this item cannot be set.

*2: The assignment share is an approximation, and there are cases when data is not assigned exactly according to specification. When the assignment share has been omitted, relocation is performed according to the Tiering policy.

*3: This can be specified when utilizing the Automated QoS function.
