8320+VSF

Hi,

 

did the 8320 support VSF yet ? or in roadmap ?

 

thanks

Re: 8320+VSF

The 8320 is not shipping yet. For future looking statements, like roadmap information, please contact your local Aruba Sales team or SE.

Re: 8320+VSF

The 8320 will support VSX which is a technology specifically target at a virtualized Agg/Core of networks.  Today, we utilize MC-LAG for a redundant and resiliant Agg/Core today.

 

What is VSX?

VSX (ArubaOS-CX) is a Virtualized Core and Aggregation solution designed ground up to meet the high availability, virtualization and simplicity needs unique to the core of the network. VSF (ArubaOS-Switch) is a Virtualized switching solution that provides simplicity and high availability and is an optimal design for access platforms. These two great high availability technologies will play important roles in their respective areas of our portfolio. 

 

The VSX design is purpose built for core and aggregation networks delivering the best combination of today’s solutions like MC-LAG and VSF. It is designed for high availability in every aspect and we will enhance the solution to ease deployment, enable flexibility in design and provide tools to make it easy to manage and troubleshoot. VSX enables a distributed and redundant architecture that is highly available during upgrades inherently by architecture design. Operationally, VSX will include features to ensure enhanced and robust configuration and consistency checking and tools to make upgrades easy and minimally disruptive.

Re: 8320+VSF

As of today though what are the options to stack two 8320s i have a pair im using as the core of a small business network of a colapsed core design. Its appears VSX isnt in the firmware yet?

Hi Rob, 

 

how many units can 8320 stack?

 

Kind Regards,

Re: 8320+VSF

VSX will be in beta soon and will be available to our customers in the 10.1 release of code coming out later this summer.  Aruba will be adding further innovations to VSX in future releases of code.  You will be able to stack 2 8320's together in a VSX configuration.

Re: 8320+VSF

Rob,

   Thanks for the information, however i bought a pair of 8320s after being told i could use them HA, im assumming my only real option currently is MCLAG? seems the 8320 was released a bit early.

Re: 8320+VSF

That is correct.  ArubaOS-CX 10.0 code provides a high level of resiliancy and redundancy utilizing MC-LAG.  VSX adds all the bells and whistles to simplify deployment, add sync features, active-active features, etc..  Please feel free to reach out to me on e-mail rob.a.haviland@hpe.com and we can help with your initial MC-LAG configurations.

8320 / 8400 / ArubaOS-CX High Availability using MCLAG

The ArubaOS-CX operating system supports HA using an advanced implementation of MCLAG TODAY. It is at the same or higher level than similar technologies in the market.

The MCLAG solution is the same for 8400 and 8320 switches.

The MCLAG elements are: 

  • Control plane: Inter-Switch-Link and Keepalive
  • Data plane L2: MCLAGs
  • Data plane L3: Active gateway

What is MCLAG?

MCLAG is the technology that allows for the configuration of link-aggregation-groups (LAG) with member ports distributed across two chassis.

MCLAG is also the name of these distributed LAGs. These MCLAGs are layer 2 LAGs, and are the optimal solution when connecting layer 2 access devices like access switches and mobility controllers.

Why MCLAG?

MCLAG's main advantage is that it provides redundancy by providing dual homing to layer 2 access devices without the need for STP and at the same time keeps the management and control planes of the two aggregation devices independent, maximizing availability.

Control plane

The inter-switch-link is:

  • a function that implements the coordination and synchronization of MCLAG information like LACP neighbors, MAC address tables, etc.
  • configured on a link between the two chassis implemeting MCLAG - this link is not dedicated to this function, and it can and does carry other traffic

A separate IP-based keepalive mechanism completes the control plane by providing an integrity check in the case of an ISL failure.

Data plane:

MCLAGs are layer 2 LAGs configured on both chassis that connect to a single access device like a switch or mobility controller. From this 3rd device's LACP point of view, all ports in the LAG belong to a single device.

The Active Gateway is a layer 3 function of MCLAG that provides an active-active gateway for the clients connected to the access device(s).

What is VSX?

MCLAG as described above is available today.

VSX is the next generation of MCLAG, that will simplify the deployment, streamline the configuration, ensure configuration consistency across the two chassis, and take advantage of the unique database-centric OS architecture to provide deeper visibility into MCLAG's management, control and forwarding planes.
