Docs latest icon.png Welcome to the latest SEP sesam documentation version 4.4.3/4.4.3 Tigon. For previous documentation version(s), check documentation archive.


The following minimum hardware requirements apply for SEP sesam Si3 deduplication server. Keep in mind that the following requirements represent the demand for deduplication only. In addition to these requirements, the amount of memory for the operating system and other services should be taken into account.

Productive environments
  • 16 GB RAM
  • 4 CPU cores for one Si3 data store
  • 1 TB free hard disk space
Test environments only
  • minimum 8 GB RAM
  • 2 CPU cores
  • 1 TB free hard disk space

For details on the required Java version, see Java Compatibility Matrix. Si3 is not mandatory, therefore there is no dependency rule in the RPM/DEB packages for it.

The following tables show the required additional amount of RAM and CPU cores for one Si3 data store. The TB value is the capacity of the Si3 data store.

Amount Note RAM
10 TB 2.5 GiB
20 TB 4.8 GiB
30 TB 7.1 GiB
40 TB 9.4 GiB
50 TB 11.7 GiB
60 TB 14 GiB

Note: Amount of CPU cores required for one Si3 data store. The TB value is the amount of backed up data (before deduplication)!

Example
RAM required for Si3 data store with 50 TB capacity is 16 GiB RAM for productive environment + 12 GiB RAM for 50 TB Si3 = ~ 32 GiB RAM.
Backed up data CPU cores
10 TB 4
20 TB 4
40 TB 8
80 TB 16
160 TB 32 or 64
