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.
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 Documentation - F5OS-A and F5
rSeries.F5 rSeries terminology
These are common F5OS terms.
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 the rSeries system. |
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 rSeries system. The rSeries webUI fully supports Chrome and Firefox
browsers. |
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 (my.f5.com). You can obtain add-on keys to enable additional
features and functionality.For more information about licensing your
rSeries
system, see the System licensing overview
section.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 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 User Management.
Deploy tenants
- Consider tenant resources needed with regard to the different tenant images of different sizes that are available. See theTenant Managementsection.
- 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 my.f5.com.
