2.2.4 Required Resources for Operation (for Operation as Express's Manager)

2.2.4.1 Required Disk Space for Operation

For operating ETERNUS SF Manager, in addition to disk space described in "2.2.3.1 Required Disk Space for Installation", the server on which it is installed must have free disk space as described below.

For Windows

Directory Name	Required Disk Space (Unit: MB)	Explanation
Environment Directory	a + b	a: Database capacity of the repository for Manager. Refer to "3.1.3 Estimation of Database Size" for details. b: Repository size for common control. Refer to "Estimation Formula for Repository Size for Common Control" for details.
Work Directory	c + 20(*1)	c: Required for performance management. Refer to "Disk Space Required for Performance Management" as described below for details. *1: Disk space required for the license management function

For Linux

Directory Name	Required Disk Space (Unit: MB)	Explanation
/etc/opt/FJSVswstf	a	a: Database capacity of the repository. Refer to "3.1.3 Estimation of Database Size" for details.
/var/opt/FJSVssmgr	b	b: Required for performance management. Refer to "Disk Space Required for Performance Management" as described below for details.
/var/opt/FJSVesfcm	c	c: Repository size for common control. Refer to "Estimation Formula for Repository Size for Common Control" for details.
/var/opt/FJSVesflm	20	Disk space required for the license management function

Disk Space Required for Performance Management

For performance management, add disk space as described below, depending on the number of Logical Units (LUs) on the storage device to be managed, the number of Disk Enclosures (DEs) and the number of days for which performance data are to be stored.

Storage Device	Required Disk Space (Unit: MB)
ETERNUS DX60 S2 ETERNUS DX60 ETERNUS DX80 S2/DX90 S2	8 * (240 + (1.2 + 0.3 * DEs + 0.3 * (securedLUs + securedRAIDgroups [*1])) * 1440 + (95 * DEs) + (50 * (securedLUs + securedRAIDgroups [*1]))) / 1024 + 2.61
ETERNUS DX60 S4/S3 ETERNUS AF250 ETERNUS DX200F (*2)	8 * (475 + (1.2 + 0.7 * DEs + 0.4 * (securedLUs + securedRAIDgroups [*1])) * 1440 + (290 * DEs) + (76 * (securedLUs + securedRAIDgroups [*1]))) / 1024 + 2.25
ETERNUS DX100 S4/S3 ETERNUS DX200 S4/S3 (*2)	8 * (774 + (2.2 + 0.7 * DEs + 0.2 * NASVolumes + 0.4 * (securedLUs + securedRAIDgroups [*1])) * 1440 + (290 * DEs) + (38 * NASVolumes) + (76 * (securedLUs + securedRAIDgroups [*1]))) / 1024 + 2.25

*1: RAIDgroups is the number of RAID groups created from LU.
*2: When enabling Deduplication/Compression to operate the device, you must add 170 MB to the capacity calculated by the formula.

Estimation Formula for Repository Size for Common Control

Required size (MB) = 400 + (servers + switches + devicesToBeManaged + disks + RAIDGroups + volumes) / 100 + (servers + switches + devicesToBeManaged) * users / 500

• servers : Number of Managed Servers

• switches : Number of managed switches

• devicesToBeManaged : Number of managed ETERNUS Disk storage systems

• disks : Total number of disks in each managed ETERNUS Disk storage system

• RAIDGroups : Number of managed RAID groups

• volumes : Number of managed volumes

• users : Number of users using Web Console (Number of user accounts)

2.2.4.2 Required Memory for Operation

For operating ETERNUS SF Manager, the server on which it is installed must add the following amount of memory.

4.1 GB

For the manageable environment by ETERNUS SF Manager, refer to "Appendix F Upper Limit of Manageable Environment".

Note

Set swap memory. For capacity, set the value that is recommended by the operating system.
