The SASE node-x (decoder/concentrator) storage configuration is dependent on a few configuration attributes defined in /opt/rsa/saTools/cloud/host-models.yml (referred to as host-models file) and /opt/rsa/saTools/cloud/sase-deployment-models.yml (referred to as sase-deployment-models file).
The configuration files are installed on Admin Server/Node-z during orchestration (Refer to SASE Installation Guide for details). When the SASE deployment script (nw-create-cloud-hybrid) is run for the first time, it copies both the configuration files (/opt/rsa/saTools/cloud/host-models.yml and /opt/rsa/saTools/cloud/sase-deployment-models.yml) to /root/.sase/ directory on the Admin Server/Node-z. Any subsequent SASE deployments refer to /root/.sase/host-models.yml and /root/.sase/sase-deployment-models.yml. All subsequent updates such as changing a model-name must be made to /root/.sase/sase-deployment-models.yml.
The SASE node’s disk specifications such as disk_name, disk_type, disk_size for each node along with gcp virtual machine type (machine_type) is collectively referred to as a model. Three models: c1r6m30, c1r12m60 and c1r23m120 are defined in the host-models.yml. One of these models is assigned as model-name attribute value in sase-deployment-models.yml.
The SASE node(s) deployment and storage configuration are tightly coupled and storage needs should be considered before installation or deployment. The SASE Installation guide should be cross referenced for complete attribute definition in host-models and sase-deployment-models files. As a best practice, the storage requirements should be identified and host-models.yml and sase-deployment-models files updated before deploying or installation of the nodes.
The below outlines the steps for successful installation and storage configuration of SASE nodes in GCP.
-
Identify the storage requirements for each of the SASE services - decoder and concentrator.
-
Identify or define the storage model: Identify a predefined model or define a new custom model. If defining a custom model, copy the /opt/rsa/saTools/cloud/host-models.yml and /opt/rsa/saTools/cloud/sase-deployment-models.yml to /root/.sase/ and update the model-name attribute for every node in /root/.sase/sase-deployment-models.yml.
-
Deploy the SASE GCP nodes: Execute the nw-create-cloud-hybrid script on admin node or node-z to complete the installation. Refer to SASE Installation Guide for details.
-
Complete storage configuration using Explore view of the Decode or Concentrator by logging into Admin Server or UI.
