Supported |
| Δ | Added or changed information since the last release, modification, or fix pack. This mark in the far left column indicates new or changed information in the row. |
| x86 | Systems with processors that support the x86 instruction set. |
| x86-64 | Systems with processors that support the x86-64 instruction set. |
| POWER | Systems with IBM POWER-based processors, including IBM System p, eServer pSeries, System i and eServer iSeries servers. |
System size capacities
The following table provides the size capacities for small, medium, and large eDiscovery Analyzer systems.
| System size | Number of documents to be processed |
|---|---|
| Small | Suitable for up to 250,000 total documents under management. Usually one eDiscovery Analyzer server. |
| Medium | Suitable for up to 2 million total documents under management. Usually one or two eDiscovery Analyzer servers. |
| Large | Suitable for up to 10 million total documents under management. Usually four eDiscovery Analyzer servers. |
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.
If your system size is large, your helper servers can be medium. If your system size is medium, your helper servers can be small.
| System size | Processor requirements | Memory requirements |
|---|---|---|
| Small | 2 processors per server. 64-bit recommended. |
4 GB, plus 4 GB paging space. |
| Medium | 4 processors per server. 64-bit required. |
8 GB, plus 4 GB paging space. |
| Large | Minimum 8 processors per server. 64-bit required. |
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 server configuration, the disk space requirements affect the main server in the eDiscovery Analyzer setup, as all the case related data is stored on the main server. On the helper servers, there is no specific disk requirement other than the minimum disk requirement to install.
Required disk space must be 3 times larger than the sum of all index sizes because during an index merge, the unpacked files create two copies. The files, when merged, create an additional third copy. The first two copies are subsequentially deleted.
The following disk space requirements are suggested for the main eDiscovery Analyzer server for an average use case.
| System size | Disk space requirements |
|---|---|
| Small | 100 GB |
| Medium | 500 GB* |
| Large | 1 TB* |
* 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.
Fix Pack 4 Space Requirements
IBM eDiscovery Analyzer Fix Pack 4 requires the following amount of disk space:
AIX
- 920 MB of temporary disk space to install the fix pack.
- 460 MB of disk space for the installed fix pack.
Windows:
- 910 MB of temporary disk space to install the fix pack.
- 455 MB of disk space for the installed fix pack.
Server hardware and operating systems
IBM eDiscovery Analyzer requires one of the following operating systems and the associated server.
| Operating system | x86 | x86-64 | POWER | Notes |
|---|---|---|---|---|
| AIX® V6.1 (64-bit) | |
Minimum: One two-way POWER server. |
||
| AIX V5.3 TL 7 or later (64-bit) | |
Minimum: One two-way POWER server. |
||
| Microsoft Windows Server 2008, 2008 R2 | |
|
Minimum: One server with two or more processors. |
|
| Microsoft Windows Server 2003 SP2 or R2 | |

Software
IBM eDiscovery Analyzer requires IBM eDiscovery Manager Version 2.2 Fix Pack 4, AIX or Windows, as a prerequisite.
Content management servers
IBM eDiscovery Analyzer must be configured to connect to a content management server that contains cases created in IBM eDiscovery Manager.
For a complete list of the supported content management servers and supported content archives, refer to the System requirements for IBM eDiscovery Manager Version 2.2 Fix Pack 4.
Virtualization support
IBM eDiscovery Analyzer is supported running within VMWare ESX, IBM PowerVM Hypervisor, and some configurations of AIX workload configurations.
Note: In all virtual environments, each runtime instance of eDiscovery Analyzer must be supported by its own independent installation of product files.
eDiscovery Analyzer's performance might be impacted when running in a virtual environment. This should be taken into account when sizing your virtual environment.
