On-Premises Fabric Configuration Parameters
This page describes the configuration values that you need to specify to create a new fabric that is hosted on-site.
Parameters with an asterisk (*) are required. Before you can initiate the Create process, you must specify all required parameters.
Creating an on-premises fabric requires you to provide host nodes before starting fabric creation. These nodes must meet certain prerequisites. Before creating an on-premises fabric, review Prerequisites for On-Premises Installation.
- Name*
- Name of the fabric. Use a name that is unique across all of your fabrics and is from 1
to 40 characters. The name:
- Must start with a letter (either lowercase or uppercase).
- Can contain lowercase letters, uppercase letters, numbers, and hyphens.
- Must not contain consecutive hyphens.
- Must include a letter or a number as the final character.
- Provider
- The cloud or on-premises platform where you want to create the fabric. Select On-premises.
- Username*
- The SSH username.
- Password*
- The SSH password.
- Airgap repository
- The repository for the Installer to use if your installation cannot access the internet.
The repository must contain nested folders. For example:
./installer/redhat
. You must create this repository before installing an air-gapped fabric.
- Data-at-rest encryption
- Data on disk (or data at rest) on a secure fabric can be encrypted, enabling you to protect the data if a disk is compromised. Encryption of data at rest not only prevents unauthorized users from accessing sensitive data, but it also protects against data theft via sector-level disk access. Data-at-rest encryption is ON by default.
- IPv6 support
- The setting that enables or disables support for IPv6 network addresses. For more information about IPv6, see IPv6 Support in Data Fabric.
- Nodes*
- The recommended minimum number of nodes that should be allocated. The form provides this information based on the Storage tier you selected.
- Node FQDN
- The fully qualified domain name of a node that will host the fabric. This is a required
field. Specify the FQDN of a node that you provided, as described in Prerequisites for On-Premises Installation. For example:
mynode.lab.mycompany.net
. Use fully qualified domain names (FQDNs). DO NOT specify hostnames as aliases or IP addresses.
- EDF subnet
- The Data Fabric subnet. This parameter is optional. This
parameter allows you to set a subnet mask to restrict fabric services to a subset of
network interface cards (NICs). Specify one or more comma-separated subnet masks. For
example:
10.10.15.0/24,10.10.16.0/24
- EDF external
- The Data Fabric external IP addresses for the CLDB, file
system, and MAST Gateway nodes. This parameter is optional. This parameter allows you to
designate a specific IP of the host as a public IP address to handle the external traffic
targeted to the host. Specify a comma-separated list of tuples using this format:
<hostname>:<host_external_IP_address>
. For example:host1.corp.net:1.1.1.1,host2.corp.net:1.1.1.2,host3.corp.net:1.1.1.3
