2. In the General group box: a. In the Include default value column on the left, check the appropriate boxes to include properties in the template. The list of values for each property are listed in the Defined default value column on the right. Include any properties for which you wish to define specific values to be used by the template. Checking the Allow override checkbox allow users to modify that property's value when applying the template. b. Use the following table as a guide when choosing which properties to include: Property Allocation Warning Growth Increment Growth Warning Growth Limit Device Type Device RPM Include in the template in order to... Specify the percentage of used copy administration or copy space which results in an alert. Set the growth increment, different than the default. The minimum growth increment and default varies according to the number of controller nodes in the system (see table): # of Nodes Default Minimum 1-2 32GB 8GB 3-4 64GB 16GB 5-6 96GB 24GB 7-8 128GB 32GB Set the threshold when the LD space exceeds this amount. Set the threshold at which the system stops creating additional LDs to support volumes that draw space from a CPG. Set the disk type to Fast Class (FC), Nearline (NL), or Solid State (SSD). Set the disk speed. NOTE: The Device RPM number does not represent a rotational speed for the drives without spinning media (SSD). It is meant as a rough estimation of the performance difference between the drive and the other drives in the system. For FC and NL drives, the number corresponds to both a performance measure and actual rotational speed. For an SSD drive, the number is to be treated as relative performance benchmark that takes into account in I/O per second, bandwidth, and the access time. RAID Type Set Size Set the VV's RAID type. Specify the VV's set size. 3. Click Next to enter allocation settings information, or click Finish. Allocation Settings 1. In the Include default value column on the left, check the appropriate boxes to include properties in the template. The list of values for each property are listed in the Defined default value column on the right. Include any properties for which you wish to define specific values to be used by the template (for example, a step size of 128 KB). Checking the Allow override checkbox allow users to modify that property's value when applying the template. 2. Use the following table as a guide when choosing which properties to include: Property Availability Step Size Include in the template in order to... set the level of failure tolerance for a volume created with this template.
