Memory and Processors

The following table specifies basic server processor and RAM requirements for an eDiscovery Analyzer system. To optimize performance, different processor and memory configurations are suggested for small, medium, and large systems. For multiple server configurations, ensure that you have the same processor and memory model on all eDiscovery Analyzer servers.

	System size	Processor Requirements	Memory Requirements
Δ	Small	2 processors per server	4 GB, plus 2 GB paging space
	Medium	2 or 4 processors per server	4 GB, plus 4 GB paging space
	Large	Minimum 8 processors per server	16 GB, plus 4 GB paging space

Disk space

The minimum disk space required to install eDiscovery Analyzer is 1 GB, plus 1 GB of temporary space.

The disk space requirements for running the system can vary and depend on the average document size, the number of documents in the case, and number of cases.

For a multiple node configuration, the disk space requirements affect the main node in the eDiscovery Analyzer setup, as all the case related data is stored on the main node. On the helper nodes, there is no specific disk requirement other than the minimum disk requirement to install.

The following disk space requirements are suggested for the main eDiscovery Analyzer node for an average use case.

	System size	Disk Space Requirements	Memory Requirements
Δ	Small	100 GB	4 GB, plus 2 GB paging space
	Medium	500 GB*	4 GB, plus 4 GB paging space
	Large	1 TB*	16 GB, plus 4 GB paging space

* In multiple server configurations, the main server hosts all the case related data and indexes, therefore requiring the listed amount of space. The helper servers are used for processing power.
