F.1 Determining Number of Manageable Devices

The number of manageable devices by one ETERNUS SF Manager is determined using the following evaluation formula. If the value calculated by the evaluation formula (comprehensive evaluation value) exceeds 2048, allocate the devices to multiple ETERNUS SF Managers to manage.

Comprehensive evaluation value = Basal value
                               + Evaluated value of registered device
                               + Evaluated value of fault monitoring
                               + Evaluated value of performance management
                               + Evaluated value of AdvancedCopy Manager
                               + Evaluated value of Automated QoS function
                               + Evaluated value of Reporting function
                               + Evaluated value of Storage Cluster function
                               + Evaluated value of VMware vSphere Virtual Volumes function

Basal Value

This is a value required for behaviors of ETERNUS SF Manager (including the Automated Storage Tiering). Specify the following value:

Basal value = 560

Evaluated Value of Registered Devices

For evaluated value of registered device, specify the value calculated by the following formula:

Evaluated value of registered devices = Evaluated value 1 per model
                                      + Evaluated value 2 per model
                                      + Evaluated value 3 per model
                                      + Evaluated value 4 per model
                                      + Evaluated value 5 per model
                                      + Evaluated value 6 per model

Evaluated Value 1 to 6 per Model

For evaluated value per device, select the appropriate value for a device to be registered from the table below.
If the number of devices to be registered is 6 or less, specify the values only for the number of devices to be registered. If the number is 7 or more, specify the 6 largest evaluated values of the devices.
