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. 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 Relativity System Requirements - 3

4 Hardware requirements (single server 25-50 named users) kcura supports the installation of all Relativity components on a single device for 25-50 named user agreements. We also recommend that a hypervisor is installed to this device so each Relativity role has its own virtual machine. Hardware Memory Processor Minimum Requirements 128GB RAM 16 logical cores (2GHz) Storage This server can be attached to a storage device (SAN, DAS, NAS). See Storage on page 10. 5 Hardware requirements (multi server 100 or more named users) The following table lists the minimum hardware requirements for a Relativity installation. Note: Depending on the type of file storage system, the File server role may not require a physical server or VM. Server Role Minimum Hardware Requirements Agent (Background Processes) Memory: 4GB RAM Network: Gigabit Ethernet Agent (dtsearch) Memory: 4GB RAM Network: Gigabit Ethernet Analytics (Search) Memory: 32GB RAM Network: Gigabit Ethernet File (Document) Memory: 4GB RAM Network: Gigabit Ethernet Relativity System Requirements - 6

Server Role SMTP (Notification) Minimum Hardware Requirements Relativity requires an active SMTP server on your network. It interfaces with this server to send notifications and monthly billing statistics. The hardware requirements for this role are minimal. You can leverage an existing SMTP server in the network or merge this server with the agent server role. SQL (Native Imaging/Processing) Memory: 16GB RAM Network: 4 Gbps to storage SQL (Workspace Databases) Processor: 8 cores (2GHz) Memory: 64GB RAM Network: 4 Gbps to storage Web (Application) Memory: 4GB RAM Network: Gigabit Ethernet Worker (Native Imaging/Processing) Memory: 8GB RAM Network: Gigabit Ethernet 6 Infrastructure configuration Relativity supports the following technologies as part of its infrastructure configuration: Virtualization kcura suggests virtualizing all Relativity roles with the exception of SQL. 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. 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. Relativity System Requirements - 7

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. 6.1 Guides for infrastructure management Review the following guides to become familiar with best practices for managing the Relativity infrastructure: Pre-Installation Guide Optimization Guide Solutions for Very Large Workspaces o o Infrastructure Workflow Infrastructure Planning Recommendations Performance metrics and recommendations 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: 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. Tier 1 Entry Level Tier 2 Mid-Level Tier 3 Enabled User Accounts < 300 300-1000 1000+ Simultaneous Users < 100 100-500 500+ Large Scale Relativity System Requirements - 8

This table lists the recommendations for environments at Tier 1. Tier 1 Quantity RAM (GB) vcpu Entry Level Web 2 8 4 Agent 2 4 4 Analytics 1 32 4 Worker 1 16 8 For Tier 2 environments, additional virtual machines are recommended as well as increased RAM and vcpus as illustrated in the following table. Relativity System Requirements - 9

Tier 2 Quantity RAM (GB) vcpu Mid-Level Web 4 8 4 Agent 4 8 8 Analytics 2 64 4 Worker 4 16 8 8.2 SQL servers The number of SQL Servers is influenced by HA and DR requirements as described in Infrastructure configuration on page 7. You can distribute Relativity workspace databases across multiple SQL instances. The recommendations for Tier 1 environments are listed in the following table. Tier 1 Quantity RAM (GB) CPU Entry Level SQL (Workspace Databases) 1 64 8 SQL (Native Imaging/Processing) 1 16 4 For Tier 2 environments, the number of SQL Servers as well as RAM and CPU is twice that recommended for Tier 1, while the Native Imaging and Processing recommendations remain the same. Tier 2 Quantity RAM (GB) CPU Mid-Level SQL (Workspace Databases) 2 256 16 SQL (Native Imaging/Processing) 1 16 4 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. Data Type 25-50 Named Users 100+ Named Users Disk I/O Example RAID Type SQL Databases 500 GB 750 GB High 5 5+0 1+0 The databases can live across multiple storage volumes and SQL instances. SQL Full Text Indexes 150 GB 250 GB Moderate 5 5+0 1+0 Index size depends on the number of fields and records indexed. SQL Database Logs 150 GB 250 GB High 1 1+0 Transaction log backups or a simple recovery models keep these values small. SQL Tempdb 80 GB 80 GB High 1 1+0 kcura recommends eight 10GB Tempdb data files for new deployments. Relativity System Requirements - 10

Data Type 25-50 Named Users 100+ Named Users Disk I/O Example RAID Type SQL Backups 500 GB 1000 GB Low 5 5+0 1+0 kcura recommends having a backup strategy. This volume is not required. Larger data sizes may require higher I/O throughput. dtsearch Indexes 150 GB 250 GB Moderate 5 5+0 The dtsearch index share is typically stored in the same location as the files. Analytics Indexes 150 GB 250 GB Moderate 5 5+0 The Analytics index share is typically stored in the same location as the files. Files (Natives/Images) 1500 GB 3000 GB Low 5 5+0 The files may not require a Windows installation depending on the storage. Multiple Processing Workers online will require more file storage I/O. Worker (Native Imaging/Processing) 100 GB 250 GB High 1 1+0 This houses temp files created by the native applications during imaging. This temp location never exceeds 250GB for each Worker server. 9 Obtaining applications for native imaging and processing On the Relativity Native Imaging/Processing worker, you must install additional software to support imaging/processing.
