  • PostgreSQL supported configuration includes case sensitive and Unicode implementation.
Email Engine

Microsoft Exchange Server 2016 (64-bit) and Microsoft Office 365 Exchange

Notes:

  • BMC internally certifies Email Engine with Microsoft Exchange Server and Microsoft Office 365 Exchange. Because Email Engine makes use of JavaMail API that is capable of working with other SMTP servers, SMTP servers that are not listed in this table might still operate correctly with AR System. You might be able to run AR System in a configuration not listed as supported. However, BMC has not certified the integration of Email Engine with such SMTP servers in their labs.
  • Microsoft has discontinued MAPI support in Microsoft Exchange Server 2016; Support for EWS (exchange web service) is available for Microsoft Exchange Server 2016 only.
    See, https://docs.microsoft.com/en-us/exchange/new-features/discontinued-features?view=exchserver-2016.
  • OAuth 2.0 based authentication is required for Microsoft Office 365 Exchange starting with 20.02.01 and later
  • Starting with AR System 20.02.01 (also known as 20.02 Patch 1), Email Engine supports OAuth 2.0 based authentication for the Exchange Web Services (EWS) protocol to access Microsoft Office 365 Exchange.
    For more information, see AR System 20.08 enhancements in the AR System online documentation.
Metrics Server

BMC Helix uses the HorizontalPodAutoscaler (HPA) for its services so that the product can scale based on the customer usage. For the HPA to function, Kubernetes must expose metrics that are used to trigger scaling activities, for which a Metrics Server is required.

For information about the HPA, see this page in the Kubernetes documentation .

For information about the Metrics Server, see this page in the Kubernetes documentation .

sshpass program

The sshpass utility helps administrators use the 'ssh' connection type with passwords. Install the sshpass program to easily manage SSH connections in scripts.

For more information, see To install sshpass.

Jenkins server requirements

Review the following requirements for the Jenkins server: 

Component

Node

vCPU

Operating System

RAM (GB)

Disk (GB)

Jenkins server14
  • Cent OS 7.x and RHEL 7.x are certified.
  • Equivalent releases of Fedora and Oracle Linux are supported.
Minimum 16 GB200

For information about setting up BMC Deployment Engine, see Setting up BMC Deployment Engine.

To install sshpass program

Install sshpass, if not already installed by using the following steps:

  1. Verify that sshpass is not already installed in your system. The following command checks if sshpass is available in any of the available repositories.

    # which sshpass

    If sshpass is not found on any of the available repositories, the following response is returned:

    /usr/bin/which: no sshpass in
  2. Use the following command to know the possible repositories in which sshpass is available on the system:

    # yum provides sshpass
  3. Install sshpass by using the following command:

    # yum -y install sshpass
  4. Verify that sshpass is installed in your system by using the following command:

    # which sshpass

Harbor repository requirements

Make sure that your system meets the following requirements to access images from a local Harbor repository:

RequirementDescription
Hardware

Minimum 4 CPU with 8 GB memory and 500 GB disk space

Software
  • Docker Engine version 20.10.7
    To install Docker Engine, see Install Docker Engine .
  • Docker Compose version 1.29.2
    To install Docker Compose, see Install Docker Compose .

Namespaces

Review the following requirements for the namespaces in your cluster: 

  • Namespace to install the common services provided by BMC Helix Platform.
  • Namespace to install EFK for logging.
    For information about creating namespaces to install BMC Helix Platform services and EFK, see Setting up the installation environment.
  • Namespace to install BMC Helix IT Service Management.
    Make sure that the namespace name consists of only lowercase alphanumerics and hyphens. Example, 'bmc-itsm'.

The actual namespace names are specific to your environment.

Important

To support Elastic deployment, increase the maximum number of memory maps on each worker node by running following command:

 # echo vm.max_map_count=262144 > /etc/sysctl.d/es-custom.conf

 # sysctl -w vm.max_map_count=262144

 For more information, see https://www.elastic.co/guide/en/elasticsearch/reference/current//vm-max-map-count.html.

    Hi, I'm missing the system requirements for the "deployment engine" in this area.

      Hi Eric,

      it's here https://docs.bmc.com/docs/brid2105/setting-up-bmc-deployment-engine-1012762678.html

    I'm missing information on the number of required nodes? Are there recommendations on number of nodes depending on planned customer size?

    1. Ariel Manka

      Hi Andreas,

      As a general rule any odd number of 3 or more should be able to do the trick. If you take the specs from here https://docs.bmc.com/docs/brid2105/system-requirements-1002902065.html you will see that recommended number of CPUs on worker node is 8. When you unzip "Helix on prem deployment manager" you will find configuration files in the ./helix-on-prem-deployment-manager/configs. For instance poc.config has an entry for TOTAL_REQUIRED_CPU=150 which means that you need 150 CPU cores available on all worker nodes in total. This is a ridiculous number and means that you need at least 19 worker nodes. I have three worker nodes with 16 CPU each and I edited that file to more reasonable 50 total CPUs. Perhaps someone from BMC could review the requirements here? It will be joy explaining why production large environment needs 600 CPU cores. Similar scenario with RAM: TOTAL_REQUIRED_RAM=327798360 (327MB or am I converting something wrong?)

        This page does not currently show the sizing information for an overall deployment. We expect to be able to publish guidance on approximate sizing for Innovation Suite deployments in the coming few weeks.

        Until then we are able to provide provisional sizing estimates for customers who urgently need this information in order. You can reach this service by contacting your partner or account manager.

        Until we have issued formal sizing guidance, please do not plan sizing based on the data in this configuration file!

        For the avoidance of doubt:

        • An odd number of worker nodes is not a requirement, this typically applies to Master or Control nodes.
        • 8 CPU is listed as the minimum for a worker node. You may have any number or profile of worker nodes as long as you meet the overall compute requirements, which we will publish.

    Hi,

    Could you please specify if the requirements: The storage of 60gb is that a separate disk from the OS boot disk? Or same boot disk plus 60G per node?

    Oct 01, 2021 01:29
    1. Poonam Morti

      Hi Gerardo,

      The storage of 60 GB can be same disk. However, the 60 GB storage is in addition to OS.

      Thanks,

      Poonam

      Hi Jani,

      RHEL 8 is not supported. The supported version is RHEL 7.

      Thanks,
