Quick Requirements Run-through

Production Environments

  • 32 GB minimum RAM recommended
  • Minimum free disk space depends on project requirements, should be above dev environment requirement for disk space

Development and Testing Environments

  • 8 GB minimum RAM recommended
  • 10 GB minimum free disk space recommended


Basic Aspire has a fairly small footprint. Dev/Test installs can be done on any modern (<5 years of age) mid-high spec laptop. For most production implementations, we recommend:

  • A server with >=4 physical core processor running a 64-bit Linux or Windows instance with Java 11 SE 64-bit properly configured.
  • JVM Heap Size set to a minimum of 8 GB RAM (32 GB recommended for production).
    • Heap Size allocation can be modified at startup, please change corresponding heap settings in <aspire install path>/bin/aspire.bat or <aspire install path>/bin/
    • For Aspire instanced installed as a service, please check the guides for Run as a Windows Service or Run as a Linux Service.

    • 8 GB is the minimum recommended heap size for lightweight Aspire instances. This may change depending of the content sources and the data to process.
  • Minimal disk space: The Aspire binaries and dependencies take up less than 1GB; however we recommend a minimum of 10 GB free disk space for development and testing environments
    • We don't recommend the minimal disk space for production environments - we've observed production environments that easily occupy scores of GB of disk space
    • Logs and data generated from crawls and other component activity will occupy additional disk space aside from what's mentioned above. Please plan your storage needs accordingly.

  • Network connection speeds of 100 Mbps minimum, preferably 1 Gbps or 10Gbps. If using an online instance of Aspire, a broadband/fiber connection with low latency is preferred for quicker Aspire component updates.

Factors Affecting Recommendations

What you need to run Aspire optimally in a complex, enterprise production environment depends on multiple factors, including:

  • The total number of data sources to be crawled, and for each data source:
    • What type of repository holds the data (i.e. SharePoint, Documentum, RDBMS, etc.)
    • Total number of documents
    • Total number of bytes
    • How long an initial indexing crawl should take
    • How long a periodic incremental indexing crawl should take
    • Are real-time updates required?
    • Network speed between repository and Aspire server
  • Data metrics for query client connections:
    • Number of client connections expected
    • Number of queries per second expected
    • Query latency times required / expected
    • Is authentication, authorization, and group expansion required for client search requests?
  • Will distributed processing be required?
