Small Deployment for Aternity 10 (up to 20,000 devices)

Use this deployment for small production environments of Aternity to support up to 20,000 monitored devices or virtual desktops, where up to 10% of them (around 2000) are virtual application sessions from up to 90 virtual application servers. It supports two Aternity users updating dashboards simultaneously, and assumes one monitored managed application per device which monitors the application's resource usage.

Important

Synchronize all Aternity components to have the same date, time AND time zone.

Hardware Specifications for Small Deployments

The small deployment requires the following hardware specifications:

Component Minimum Memory (RAM) Minimum CPU Minimum free disk space Additional configuration

Aternity Aggregation Server

8GB

Xeon E3 family, 2 cores at 2.4 GHz

30GB

JVM heap size: (learn more)

-Xmx4096m

-XX:MaxNewSize=2000m

Aternity Management Server

12GB

Xeon E3 family

4 cores

1.9 GHz

220GB

JVM heap size: (learn more)

-Xmx8192m

-XX:MaxNewSize=3072m

ActiveMQ JVM Heap Size: 1G

Aternity Dashboard Server

16GB (you can ignore the RAM size warning during setup)

Xeon E5 family

8 Cores

2.4-3.6 GHz

15MB CPU cache

300GB (SSD)

Or I/O per sec (IOPS): 900

For less standard hardware configurations, see the setup instructions and hardware best practices from Tableau. To deploy on a virtual machine, you must guarantee the CPU and memory requirements.

Aternity Oracle Database Server

12GB

Xeon E3 Family

4 Cores

2.4 GHz

800GB

I/O per sec (IOPS): 800

Oracle's System Global Area (SGA): 8GB

Program Global Area (PGA): 2GB

If you lengthened the retention of some REST APIs (learn more), increase disk by 10GB.

(Aternity upgrades only) If you reduced the retention of Performance Navigator (learn more) to just three months, reduce disk space by 170GB. For only one month's retention, reduce by 210GB.

Aternity Vertica Database Server

32GB

Xeon E5 family

8 Cores

2.4-3.6 GHz

15MB CPU cache

200GB (SSD) in total

Or I/O per sec (IOPS): 900

The disk space is the total required for all Vertica Database Servers together in a cluster, before any high availability (k-safety = 0). For minimum high availability, we recommend at least k-safety = 1 (learn more): 3 servers x 135GB each.

If you deploy on virtual machines, you MUST define all resources as dedicated or reserved (Resource Allocation > Reservation).

Aternity ETL Server

8GB

Xeon E5 family

2 Cores

2.4-3.6 GHz

80GB (SSD)

Includes swap file: 6GB

Aternity Data Source for Portal (optional) and Aternity REST API Server (optional)

8GB together, 4GB each if you separate them

Xeon E3 family

2 Cores

2.4-3.6 GHz

80GB (SSD) together, 40GB (SSD) each if you separate them

Optional. Only required if you use this functionality.

Tip

The setup checks free disk space under the logs directory (/var/log). If you are short on disk space for the setup directory, you can map this directory (soft link) to a different drive.

You must also install each server with the required operating system and other software. For details, see the system and software requirements for each server.
