On systems running Solaris
The Cell Manager must meet the following minimum requirements:
• 256 MB of RAM (512 MB recommended)
For each parallel backup session, 40 MB of RAM are required and 5–8 MB per data segment size.
This means that, for example, if you want to run 60 parallel backup sessions 3 GB of RAM plus 512
MB of data segments are needed.
• 300–425 MB of disk space + approximately 2% of planned data to be backed up
(for use by the IDB)
• The following values of kernel parameters are recommended: SEMMNI (maximum number of
semaphore sets in the entire system) = 100 SEMMNS (maximum semaphores on the system) = 256
A system restart is necessary for kernel changes to take effect.
On systems running Windows 2000 or Windows XP
The Cell Manager must meet the following minimum requirements:
• 256 MB of RAM (512 MB recommended).
For each parallel backup session, 40 MB of RAM are required. This means that, for example, if you
want to run 60 parallel backup sessions 3 GB of RAM are needed.
• On Windows 2000 systems, Service Pack 3 or later must be installed.
• On Windows XP Professional systems, Service Pack 1 must be installed.
• 190 MB of disk space + approximately 2% of planned data to be backed up (for use by the IDB)
• 2 × size_of_the_biggest_package_to_be_installed + 5MB of disk space needed on system drive
On systems running Windows Server 2003 or Windows Server2008
The Cell Manager must meet the following minimum requirements:
• 256 MB of RAM (512 MB recommended).
For each parallel backup session, 40 MB of RAM are required. This means that, for example, if you
want to run 60 parallel backup sessions 3 GB of RAM are needed.
• 190 MB of disk space + approximately 2% of planned data to be backed up (for use by the IDB)
• 2 × size_of_the_biggest_package_to_be_installed + 5 MB of disk space needed on system drive
• On Windows Server 2008 systems, the firewall must be configured to accept “Remote Service
Administration” (NP) connections (port 445) additionally.
• On Windows Server 2008 systems, administrative privileges are required to install
