Groundplex requirements: Hardware and operating systems

Computing requirements

Hardware requirements

A Groundplex is a local server running on hardware that you provision. The hardware must meet the following minimum requirements.

Nodes Minimum value: 1

Recommended: 2 or more nodes

 Groundplex nodes can be configured in the following sizes:
  • Medium: 2 vCPU and 8GB RAM
  • Large: 4 vCPU and 16GB RAM
  • X-Large: 8 vCPU and 32GB RAM
  • 2X-Large: 16 vCPU and 64GB RAM

SnapLogic recommends two nodes for high availability. For requirements about clustering nodes, refer to the Node Cluster section in Groundplex Requirements.

Important: All JCC nodes should be alike. Similarly, all FeedMaster nodes should be alike. However, JCC nodes can be (and typically are) larger than FeedMaster nodes.
RAM Minimum value: 8GB Depending on the size, number, and nature of pipelines, more memory (RAM) might be required to maintain an acceptable level of performance. The memory used depends on the volume and size of the documents being processed. Some Snaps, like the Sort Snap, hold many documents in memory during processing and, therefore, consume more memory.
Note: Contact your SnapLogic Sales Engineer to perform an optimum-sizing analysis based on your requirements.
CPU Minimum value:
  • 2 cores
  • 64-bit Architecture - Intel or AMD
 All Snaps execute in parallel in their own threads; therefore, the more cores that are available to the Snaplex, the more performant the system.
Disk Space Minimum value: 80GB

Recommended: 100GB

 Local disk space is required for logging and for any Snap that uses the local disk for temporary storage, such as the Sort and Join Snaps. For details, refer to Temporary Folder.
Note: SnapLogic does not restrict the disk size of your Groundplex nodes.

Supported operating systems

Groundplexes are certified as supported on the following operating systems:
  • Linux: Debian-based and Red Hat-based distributions. Both *.deb and*.rpm packages are available for download via the Snaplex dialog.
    CAUTION: In general, any Linux version that has not reached end-of-life and is still supported by the vendor should work but might not be certified by SnapLogic.
  • Windows: Any version that has not reached end-of-life and is still supported.

CPU Clock Alignment

CPU clock alignment is an important consideration for Groundplexes, especially those in production environments. The Date.now() expression language function might be different between Snaplex nodes, and internal log messages might have skewed timestamps, making it more difficult to debug issues. For example, with Ultra Tasks, large clock differences can also affect communication between the FeedMaster and the JCC nodes.

The Groundplex machine timestamp is verified to check if it is in sync with the timestamp on the SnapLogic cloud. Running a time service on the Groundplex node will ensure that the timestamp is always kept in sync.
