System Overview
Introducing F5 rSeries systems
F5
rSeries
platforms are powerful systems that are designed specifically for application
delivery performance and scalability.F5
rSeries
systems include a platform layer that runs F5OS-A software, on which you can have multiple tenants. A tenant is a guest system running software (for example, a BIG-IP system). F5 r5000/r10000 platforms
can run a minimum of eight tenants up to 36 tenants. F5 r2000/r4000 platforms
can run a single tenant on the low end and up to four tenants on the higher end.This illustration shows a simplified
rSeries
deployment. The rSeries
system shown here has four tenants attached. In this example, you can have up to eight tenants running at one time.![](/content/dam/projects/techdocs/f5os-a-1-4-0/rseries-sw/images/rseries-diagram.png/_jcr_content/renditions/original)
F5
rSeries platforms offer upgradable three-tier Pay-as-you-Grow (PAYG) licensing options. For more information about the PAYG options, see K44211301: PAYG license support for F5 r5000 and r10000 series platforms or K44442211: PAYG license support for F5 r2000 and r4000 series platforms.For more information about
rSeries
hardware components, see the platform guide for your hardware model at techdocs.f5.comDocumentation-F5OS-A and F5 rSeries.F5 rSeries terminology
This table lists some of the terms you will encounter when configuring the F5 rSeries system.
Term | Definition |
---|---|
appliance mode |
Restricts user access to root and
Bash at the system and tenant levels. When enabled, the root
user cannot log in to the system by any means, including from
the serial console. Disabled by default. |
F5OS-A |
Platform operating system software
that runs on F5
rSeries systems. |
LAG |
Link aggregation group. A way to
group interfaces on the system so they function as a single
interface. The LAG (like a trunk on BIG-IP systems)
distributes traffic across multiple links, increasing the
bandwidth by adding the bandwidth of multiple links
together. |
port group |
A configuration object that is used
to control the mode of the physical ports, whether they are
bundled or unbundled, and adjust their speed. |
tenant |
A guest system (similar to a vCMP
guest) running software on the system. You can deploy multiple
tenants on a system. |
webUI |
Browser-based user interface for configuring the F5 rSeries
system. F5OS webUIs fully support the latest
versions of Chrome and Firefox browsers at the time of each F5OS
release. |
F5 rSeries system licensing overview
rSeries
system licensing overviewBefore you can configure and use the
rSeries
system, you must activate a valid license. The license service coordinates the license installation on the system and configures the same license on the system and the tenants. Because the license applies to the whole system, the tenants all inherit licenses from the system.A base registration key, generated by
F5
, identifies a set of entitlements and is used to obtain the license for an F5 product. The base registration key with associated add-on keys are pre-installed on a new rSeries
system. If you do not have a base registration key, contact F5 Technical Support (support.f5.com). You can obtain add-on keys to enable additional features and functionality.For more information about licensing your
rSeries
system, see F5 rSeries system licensing overview.Licensing terminology
Term |
Description |
---|---|
entitlements |
Features and functionality of an F5
product that a customer can enable by purchasing a
license. |
base registration key |
A 27-character string that informs
the license server about which F5
products are included in the license. |
add-on key |
A 7-character string that enables
features on a device, in addition to the entitlements
associated with the device base registration key. |
dossier |
A digital fingerprint of an F5 product instance. The dossier
uniquely identifies the device. |
F5 rSeries system administration user/role
overview
You can configure and manage the
rSeries
system at two different levels: the platform layer or the individual tenants. Each has their own webUI, CLI, and REST API access.The users at the platform and tenant levels are independent from each other,
and the roles and what users can do are different depending on where the account was
created. Even if one person is performing more than one role, separate accounts are
needed at each level.
These administration roles are available on
rSeries
systems:- System administrator
- Manages the whole system configuration with read-write access to all system settings. Able to change the system root and admin passwords.
- Tenant administrator
- Has access to the tenant only. Performs user management on the deployed tenant(s). No management of therSeriessystem.
F5 rSeries administration tasks overview
There are many different tasks involved in administering an
rSeries
system. Though you might have several different administrators for the system and tenants, it is useful to have a general idea of all of the tasks involved and the order in which you might perform them. This is generally the order in which things happen, and it is just an overview of the many tasks involved:Before using this guide
- Complete hardware installation. For information about the hardware, see the platform guide for your hardware model at Documentation - F5OS-A and F5 rSeries.
- Complete an initial configuration. For information about initial configuration, seeF5 rSeries Systems: Getting Startedat Documentation - F5OS-A and F5 rSeries.
- Make sure therSeriessystem is made accessible. Configure network settings, DHCP, DNS, and NTP. For information about software installation, seeF5 rSeries Systems: Software Installation and Upgradeat Documentation - F5OS-A and F5 rSeries.
Plan the configuration
- What is the network configuration at the system level, including management interfaces, port groups, interfaces, and VLANs. Will you use link aggregation or spanning tree protocol?
- How many administrators and operators will need accounts on the system? At the tenant level?
- How will system users be authenticated? RADIUS, TACACS+, or LDAP?
- How many tenants do you plan to deploy?
- What will the tenants be used for? For example, which application delivery modules will you be configuring? Multiple modules?
- The configuration can be modified later if needs change.
Configure the system
- Log in to the system.
- License the system, if it wasn't done already. See System Settings.
- Adjust network settings such as management interfaces if needed. See Network Settings.
- Optionally, create accounts for administrators, operators, or tenants. See the User Management.
Deploy tenants
- Consider tenant resources needed with regard to the different tenant images of different sizes that are available. See Tenant Management.
- Deploy one or more tenants. See Tenant Management.
- Log in to each tenant and configure the systems as needed. For BIG-IP tenants, see the BIG-IP system documentation at K000130285: F5 Product Manuals IndexK000130285: F5 Product Manuals Index .
