Like all big data applications, Gateway Hub has significant hardware requirements. Refer to the table below for our recommended hardware specifications and consult the Hardware guidelines for guidelines for components.
To get some guidance on how many nodes to include in your cluster based on the size of your Geneos estate, see Plan the cluster.
The following hardware specification is recommended for each Gateway Hub node in production:
|Component||Recommended Setup||Minimum Requirements|
|Server||2U Rack Server/Chassis.|
|System board||Dual CPU socket system board.|
|CPU||2 x 8-core 64-bit CPU, 32 cores with hyper-threading enabled.||8 cores|
8 x 8GB DIMMs, 64GB RAM (DIMM count must be multiple of CPU memory channels).
|Network||10GbE network interface.|
Note: The above server specification corresponds to the EC2 (Amazon Web Services) instance
m5.2xlarge, which is suitable for deploying Gateway Hub in the cloud.
- Use CPUs with as many cores as possible, and prioritise additional cores over a slightly higher clock speed.
- The MapR disks must be entirely SSDs or entirely HDDs on one node. Mixing disks on the same node for MapR is not supported.
- Fewer and/or smaller disks can be used for MapR. The number of disks is dependent on your organisation's storage requirements.
- An SSD is recommended for the disk for the Zookeeper transaction logs.
- SAS drives can provide better I/O latency. SSDs provide even lower latency.
- Match aggregate drive throughput to network throughput. 10GbE ~= 10-12 drives.
- Raw disks should be used instead of Logical Volume Manager (LVM).
