To install ETERNUS SF Manager, the following database is required.
Repository
This is used for the managing the information of the operating environment by ETERNUS SF Manager.
For Windows environment
The following database areas are required. The following databases must reside on a drive with NTFS format.
Type | Required size |
|---|---|
RDB log file | 100MB |
RDB dictionary | 55MB |
Repository database | Calculated value by "Formula for calculating repository database" |
The required size of the repository database must be calculated by the following formula.
Required size (MB) = {[(Number_of_servers * 6 + Total_number_of_devices * 11) / 40] * 17 + 512} / 1024Number_of_servers
This is the total number of Management Server and Managed Servers.
For servers that perform the cluster operation, calculate with the number of physical nodes that compose the clustered system.
Total_number_of_devices
For AdvancedCopy Manager
This is the total number of devices (partitions) that are managed by AdvancedCopy Manager. This is not to be confused with the total number of devices that are connected to a Managed Server.
For AdvancedCopy Manager, the meaning of "device" is as follows:
OS type of Managed Server | Meaning of "device" |
|---|---|
Windows | Partition |
Solaris | Slice |
Linux | Partition |
HP-UX | LUN |
AIX | LUN |
For Express
This is the total number of partitions. This is not to be confused with the total number of devices that are connected to a Managed Server.
If a Managed Server is mirrored by SynfinityDISK or PRIMECLUSTER Global Disk Services, the number of devices is the total number of mirror slices. The total number of mirror slices is the result of multiplying the number of devices by the number of disks composing each mirror group.
Point
Cautions for calculating the disk space for the repository database:
Round up to the integer, any fractions in the calculation results for the terms in the square brackets.
When the calculated value is less than 65MB, use 65MB as the required size.
If there is any possibility that the number of servers and/or devices will increase in the future, specify a larger disk space than calculated.
For Solaris/Linux environment
The following database areas are required.
Type | Required size |
|---|---|
DB file directory | 200MB |
RDB log file directory | 50MB |
RDB dictionary directory | 50MB |
The directory containing the repository data storage DB | Disk space that calculated in "Formula for calculating repository database". |
Note
The following when you store the above mentioned database in the new device.
A management block is required for operation with the file system when the file system is created. The size of the file system must be less than the size of the defined device.
The capacity of the management block is specified using the relevant option to when the file system it is created.
Confirm that free space listed above table is secured using df command to check the capacity of the file system after creating the file system.
Required size (MB) = {[(Number_of_servers * 6 + Total_number_of_devices * 11) / 40] * 17 + 512} / 1024Number_of_servers
This is the total number of Management Server and Managed Servers.
For servers that perform the cluster operation, calculate with the number of physical nodes that compose the clustered system.
Total_number_of_devices
For AdvancedCopy Manager
This is the total number of devices (partitions) that are managed by AdvancedCopy Manager. This is not to be confused with the total number of devices that are connected to a Managed Server.
For AdvancedCopy Manager, the meaning of "device" is as follows:
OS type of Managed Server | Meaning of "device" |
|---|---|
Windows | Partition |
Solaris | Slice |
Linux | Partition |
HP-UX | LUN |
AIX | LUN |
When the Managed Server to be managed is using mirroring with the SynfinityDISK or PRIMECLUSTER Global Disk Services, the number of devices is equivalent to the total of mirror slices.
The total number of mirror slices is the number of devices multiplied by the number of disks comprising the mirror group.
For Express
This is the total number of partitions. This is not to be confused with the total number of devices that are connected to a Managed Server.
Note
Although the four directories can be created on the same device, for reliability and performance considerations, we recommend preparing these directories on another partition.
When there are two or more Management Servers, define the number to be estimated as the total number on all Management Servers.
Round up to the integer, any fractions in the calculation results for the terms in the square brackets.
When the calculated capacity is less than 65 MB, use 65 MB as the minimum required size.
When the calculated capacity and the free space in the prepared partition are the same size, the directory usage rate (capacity), displayed by the df command or similar, may be 100%, but this is not a problem.
Point
If there is a possibility that the number of servers or number of partitions will be increased in future, specify a size that is greater than the estimated size.
If there is a possibility that the number of mirrors or number of devices will be increased in future and SynfinityDISK or PRIMECLUSTER Global Disk Services are used, also specify a size that is greater than the estimated size.
