System requirements for EcoStruxure IT Gateway

Operating system

• A server or a PC that is always on with:
  • English install of Microsoft® Windows® 10 and 11 64-bit, Server 2016, Server 2019, and Server 2022 
  • Rocky Linux 8.7 and 9.1; Red Hat Enterprise Linux 7, 8, 9; CentOS 7 (end of life June, 2024)

Support for CentOS 8 ended

Red Hat Enterprise Linux (RHEL) announced that no further operating system updates will be available for CentOS 8 after December 31, 2021. As of now, updates and security patches for CentOS 7 will be available through June of 2024.

If you installed the Gateway on CentOS 8, you should replace it with another supported operating system.

Back up your Gateway installation on CentOS 8 first, then restore it on the new operating system.

Support for CentOS 7 ending in June 2024

If you installed the Gateway on CentOS 7, consider replacing your Gateway on another supported operating system soon.

How to replace your EcoStruxure IT Gateway with a new installation

CPU and Memory

The required CPU and memory depends on the number of monitored devices and the protocol.

The following guidelines are based on our testing. Your actual results may vary due to differences in hardware, network, and device responsiveness.

The Gateway service (OpenJDK Platform binary) allocates up to half the total system memory for its use.

Recommended minimum CPU and memory

The number of SNMPv3 devices the Gateway can monitor is about 25% of what is possible with SNMPv1 and Modbus TCP. 

SNMPv1 and Modbus TCP

Size	Number of devices	Number of sensors	RAM	CPU
Small	250	34,000	4GB	4
Medium	2000	270,000	8GB	8
Large	5000	540,000	16GB	24

 

SNMPv3

Size	Number of devices	Number of sensors	RAM	CPU
Small	60	8,500	4GB	4
Medium	500	65,000	8GB	8
Large	1,200	130,000	16GB	24

 

One Minute Polling

A maximum of 25 devices can be configured to poll at 1 minute.

When you use the small Gateway configuration to discover SNMPv3 devices, only about 10 out of the 60 SNMPv3 devices can be polled at 1 minute.  More than 10 devices may cause the Gateway to become overloaded and not keep up with the configured poll rate.

See Configure 1 minute polling in EcoStruxure IT Gateway

Alarms

If the combination of number of devices, poll rate, and protocol is more than the Gateway can handle, you may get a device communication alert alarm.

 

Disk Space

800MB of disk space is required for the application itself, plus additional space for a maximum of 8 days of sensor data.

Additional disk space required

Size	Additional disk space	Total disk space
Small	128MB per day	2GB
Medium	512MB per day	5GB
Large	1.1GB per day	10GB

 

Firewall

• Intelligent Network Management Card

• Modbus TCP or SNMP V1 and V3 enabled
  Gateway versions older than 1.15 do not allow discovery of SNMPv3 devices with the Authentication type and Encryption type set to None. See Discover devices

• Connected to a TCP/IP network that the Gateway has access to
  Note: Firmware update and mass configuration with APC NMC 4 (AP9644) devices are not yet supported.

• Redfish server protocol support

  • HP Proliant with iLO 4, 5
    Note: iLO 4 requires ManagerFirmwareVersion 2.55 or greater.

  • Dell PowerEdge with iDRAC 7, 8, 9

• NetBotz support

  • Rack Monitor 570, 250, 750/755

Security certificate

When you launch the EcoStruxure IT Gateway, the browser might display a message that the connection is not secure. Since the application is installed on the local machine, the security certificate used by localhost is a self signed certificate. It is safe to add an exception to your browser for https://localhost.
