2.2.4 Required resources for operation (for Windows)

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 operation as Express's manager

Directory name	Required disk space (Unit: MB)	Explanation
Environment Directory	a + b	a: Database capacity of the repository for Manager. Refer to "3.1.4 Estimation of database size" for details. b: Repository size for common control. Refer to "Estimation formula for the repository size for common control" for details.
Work Directory	c + 20(*1)	c: Required for performing the performance management. Refer to "Disk space required for performance management" as described below for details. *1: Disk space required for the license management function

Directory name

Required disk space
(Unit: MB)

Explanation

Environment Directory

a + b

a: Database capacity of the repository for Manager. Refer to "3.1.4 Estimation of database size" for details.

b: Repository size for common control. Refer to "Estimation formula for the repository size for common control" for details.

Work Directory

c + 20(*1)

c: Required for performing the performance management. Refer to "Disk space required for performance management" as described below for details.
*1: Disk space required for the license management function

Disk space required for performance management

For performing the 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.

8 * (240 + (1.2 + 0.3 * DEs + 0.3 * (LUs + RAIDGroups)) * 1440 + (95 * DEs) + (50 * (LUs + RAIDGroups))) / 1024 + 2.61

RAIDGroups : The number of RAIDGroups created from the LUs

Estimation formula for the repository size for common control

Required size (MB) = 300 + (servers + switches + devicesToBeManaged + disks + RAIDGroups + volumes) / 100 + (servers + switches + devicesToBeManaged) * users / 500

servers : The number of Managed Servers
switches : The number of managed switches
devicesToBeManaged : The number of managed ETERNUS Disk storage systems
disks : The total number of disks in each managed ETERNUS Disk storage system
RAIDGroups : The number of managed RAID groups
volumes : The number of managed volumes
users : The number of users using Web Console (The number of user accounts)

For operation as Storage Cruiser's manager

Directory name	Required disk space (Unit: MB)	Explanation
Environment Directory	5 + 1(1) + 1.2(2) + 65(*3) + a	a: Repository size for common control. Refer to "Estimation formula for the repository size for common control" for details. 1: Configuration definition file 2: Database (co-operation with middleware) *3: Database capacity of the repository for Manager - Calculated assuming a maximum of a 100 products.
Work Directory	1055 + 35(4) + 20(5) + 20(*6) + a + b	a: Repository size for common control. Refer to "Estimation formula for the repository size for common control" for details. b: Repository for Storage Cruiser - The database requirement is calculated for 1000 registered servers and two devices for each server. (12KB * the number of registered servers + 4KB * the number of registered devices) 4: Log 5: Database *6: Disk space required for the license management function

Repository for Storage Cruiser

Add disk space as described below, depending on the numbers of storage devices, server nodes and switches to be managed.

Required size (MB) = 1 + devicesToBeManaged * 4

Add the total of disk space as described below to the above disk space, depending on the numbers of storage devices to be managed.

For ETERNUS DX80 S2/DX90 S2 (The firmware version is V10L40 or later):
```
Required size (MB) = devicesToBeManaged * 4
```
For ETERNUS DX400 S2 series (The firmware version is V10L40 or later):
```
Required size (MB) = devicesToBeManaged * 6
```
For ETERNUS DX8000 S2 series (The firmware version is V10L40 or later):
```
Required size (MB) = devicesToBeManaged * 23
```
For other than the above:
```
Required size (MB) = 0
```

Additionally, for performing the performance management, disk space is necessary depending on the number of devices from which to collect performance data and the number of days for which performance data are to be stored.

Refer to "Appendix C Required Disk Space for Performance Management" for details.

Estimation formula for the repository size for common control

Required size (MB) = 300 + (servers + switches + devicesToBeManaged + disks + RAIDGroups + volumes) / 100 + (servers + switches + devicesToBeManaged) * users / 500

servers : The number of Managed Servers
switches : The number of managed switches
devicesToBeManaged : The number of managed ETERNUS Disk storage systems
disks : The total number of disks in each managed ETERNUS Disk storage system
RAIDGroups : The number of managed RAID groups
volumes : The number of managed volumes
users : The number of users using Web Console (The number of user accounts)

For operation as AdvancedCopy Manager's manager

Directory name	Required disk space (Unit: MB)	Explanation
Environment Directory	For performing the backup operation: If not backing up the Symfoware: (a + 35 * b) / 1024 + e If backing up the Symfoware: ((a + 35 * b) + (b + 0.5 * c)) / 1024 + e	a: Number of backup volumes b: Number of transaction volumes c: Number of DSIs of all database spaces to be backed up d: Number of volume pairs for replication management e: Repository size for common control. Refer to "Estimation formula for the repository size for common control" for details.
Environment Directory	For performing the replication operation: (1.1 * d) / 1024 + e
Work Directory	1107 + f + 20(*1)	f: Capacity of saved file that is output according to "Volume lock error investigation function" in the ETERNUS SF AdvancedCopy Manager Operation Guide (for Windows). The output for each number of backup and transaction volumes and for each volume pair for replication management is made in sizes between several hundred KB and 2 MB each time an "in-use lock error" occurs. *1: Disk space required for the license management function
Database Creation Directory	g	g: Database capacity of the repository. Refer to "3.1.4 Estimation of database size" for details. Database Creation Directory is "Database creation folder" specified in "3.2 Installation procedure of ETERNUS SF Manager (for Windows)".

Assuming a size of 2 MB per saved volume file, for n times an "in-use lock error" occurs, capacity f is determined by the following formula:

f = (a + b + 2 * c) * 2(MB) * n(times)

Estimation formula for the repository size for common control

Required size (MB) = 300 + (servers + switches + devicesToBeManaged + disks + RAIDGroups + volumes) / 100 + (servers + switches + devicesToBeManaged) * users / 500

servers : The number of Managed Servers
switches : The number of managed switches
devicesToBeManaged : The number of managed ETERNUS Disk storage systems
disks : The total number of disks in each managed ETERNUS Disk storage system
RAIDGroups : The number of managed RAID groups
volumes : The number of managed volumes
users : The number of users using Web Console (The number of user accounts)
