1 System requirements
The system requirements include detailed information about the software and hardware used for
hosting Relativity in your environment. In addition, they provide various recommendations for
configuring a new deployment of Relativity, as well as scaling your environment as the number of
users and the amount of data continue to grow.
2 Scalable infrastructure example
Relativity is designed with a scalable infrastructure that you can tailor to the requirements of your
environment. It is developed on the .NET framework with a Microsoft SQL Server back-end. As
illustrated in the following diagram, all areas of the platform are scalable providing support for any
hardware vendor, hypervisor, and storage protocol.
Relativity | System Requirements - 3
3 Software requirements
Relativity has specific software requirements for servers or virtual machines, user workstations, and
the Relativity Desktop Client. The requirements for servers differ by the role assigned to them in
your system configuration.
Note: Make sure that you install the latest service packs for Windows, .NET, and SQL Server on your
machines.
3.1 System (servers or virtual machines)
The general software requirements for servers and virtual machines include Microsoft Windows
Server and .NET technologies. Microsoft Office and other applications are required for Native
Imaging and Processing servers. See Obtaining applications for native imaging and processing on
page 12.
Note: For the File (Document) role, the type of storage system used will determine if you need to install the
Windows operating system.

64-bit OS only.
4 Hardware requirements (25-50 named users)
kCura supports the installation of all Relativity components on a single device for 25-50 named user
agreements. We also require that a hypervisor is installed to this device so each Relativity role has
its own virtual machine.

Note: Based on a hard cap placed by kCura, each
Worker server is allowed to spawn 16 threads. Each
processor core and 2GB RAM will create two threads.
Therefore, we suggest allocating 8 logical cores and
16GB RAM to each Worker server for the most
throughput.
* Processing uses only up to 8 cores, in which case there is no benefit to allotting more than 8 cores
for processing. Any additional core will be used by another part of the system.
6 Infrastructure configuration
Relativity supports the following technologies as part of its infrastructure configuration:
n
Virtualization
We suggest virtualizing all Relativity roles with the exception of SQL (workspace databases). Any hypervisor is supported.
Note: Virtualizing SQL may simplify meeting HA and DR requirements. However, it can introduce additional
layers of complexity when properly configuring and troubleshooting performance and stability related issues.
We're not opposed to virtualizing SQL (native imaging/processing). This server demands less hardware
resources, and any performance issues would impact only these Relativity features.
n
n
n
n
n
High Availability (HA)
Relativity supports SQL Server Failover and File Server Clustering along with available hypervisor solutions.
Disaster Recovery (DR)
Relativity supports Microsoft SQL Server mirroring, log shipping, and SAN replication technologies.
These approaches typically require manual failover and increased downtime.
Web Server Load Balancing
Relativity supports only single affinity in Windows Network Load Balancing (NLB). The Relativity User
Load Balancer (RULB) provides the ability to distribute the user load evenly.
Perimeter Networking (DMZ)
Relativity requires certain ports to remain open for proper server communication. See the Relativity
Infrastructure Ports Diagram for details.
NIC Teaming and Multipath I/O
Relativity supports the aggregation of network or storage connections for performance and redundancy.

7 Scalability
You can scale Relativity installations to handle the performance, storage, and other environmental
factors necessary to support the addition of new users, continual growth of data, and increased
demands for searching capabilities.
7.1 Tier level definitions
kCura has identified tier levels that support varying numbers of users and sizes of active data. You
can use these tier level definitions to determine the cores, RAM, and other equipment required to
support the rapid growth of your Relativity installation. Key terms used in the following table
include:
n
n
n
n
n
Enabled User Accounts – amount of enabled Relativity User accounts.
Simultaneous Users - average amount of simultaneous users logged into Relativity.
Active SQL Data (TB) - total amount of disk space consumed by SQL databases (mdf) and full text (ndf)
indexes.
Active Record Count (MM) – total amount of records (documents) included across all active Relativity
workspaces.
Active File Size (TB) - total amount of disk space consumed by native and image files.
This table identifies the combination of users, data, and file sizes associated with each tier.

configuration on page 8. You can distribute Relativity workspace databases across multiple SQL
instances.

both Tier 1 and Tier 2 environments.

8.3 Storage
For each type of data, the amount of recommended space depends on the number of records
imported, as well as the type and length of the expected reviews. Each server or VM needs space
for the OS, page file and less than 1GB for Relativity installation files. For the Relativity Processing
SQL Server, all the same SQL data is required with the exception of SQL Full Text Indexes.
Throughput, especially when multiple SQL Servers are virtualized on a single host, should be put
through a regiment of rigorous random and sequential read/write IO testing before installation of
Relativity is completed.

9.1 Licensing Microsoft products
Relativity requires Microsoft Windows and Microsoft SQL Server, both of which you need to license
through Microsoft or one of their resellers. If using Relativity Processing or Native Imaging, you also
need to license Microsoft Office, Visio, and Project through Microsoft or one of their resellers.
If Relativity is hosted for external customers, you may need to license Microsoft products through
Microsoft’s SPLA (Service Provider License Agreement). You can find more information about
Microsoft’s SPLA program on Microsoft’s Hosting site.
kCura recommends contacting Microsoft, or one of their resellers, for guidance on the licensing
options available.
