The face of the enterprise data center has evolved in recent years. The disruptive and innovative datacenter technologies of hyperscale cloud giants are gradually making their way into enterprise data centers.

Case in point: the container orchestration platform Kubernetes, Open Compute Project OCP and composable disaggregated infrastructures CDIwhich were all created and practiced by Google, Facebook and the likes, are now touted as enterprise-grade solutions. Although public cloud adoption is progressing rapidly, public offerings have not taken over a big piece of the enterprise pie. While hybrid clouds provide a cost-effective and agile solution, they also expose organizations to a cyber threat landscape that is broad and continuously changing, fast beyond what the guards can respond to with traditional security tools.

Thus, a holistic approach is needed for enterprises to enhance their security postures and achieve a robust and complete protection. Only solutions that protect all types of workloads, at any speed and against both current and future threats can deliver the highest levels of security, integrity and reliability in the hybrid cloud era.

Micro-segmentation is an emerging data center and cloud security best practice that enables enforcement of fine-grained security policies for any network in a multi- hybrid cloud environment. It provides several advantages over the traditional approaches of using VLANs for network segmentation and firewalls for application separation.

Micro-segmentation uses software-defined controls running on each node to provide individual workload isolation and protection, reducing risks and simplifying security management. These advantages are key as enterprises adopt a hybrid cloud approach consisting of cloud services from one or multiple vendors while maintaining their own datacenters.

The rise of cloud-native applications where microservices architectures and containers create new communication frameworks reinforce the need for elastic micro-segmentation implementation.

Guardicore, a leader in the internal datacenter and cloud security realm, offers Centra, a comprehensive hybrid cloud security solution that delivers the simplest and most intuitive way to apply micro-segmentation controls to reduce the attack surface and detect and control breaches within east-west traffic. However, there are ample reasons why deploying agents is neither possible nor desired in many modern, data-driven workloads.

Some application environments, like in high-frequency trading, are optimized for high-performance, low-latency transactions. Other businesses with a track record of failed agent deployment may be reluctant to try a different one. The result is a lack of visibility, which leaves enterprises with infrastructure silos where security policy enforcement cannot be applied.

A software-defined and hardware-accelerated security policy enforcement at wire speed, fully isolated from the workload itself. The joint solution is ideally positioned to those environments in which deploying agents is not permitted:.

Deliver Predictable Networks Performance Report by The Tolly Group Understand the fundamental differences between Mellanox Spectrum and Broadcom Tomahawk based switches and the importance of predictable performance and zero packet loss.As cloud use cases and the public cloud matures, hybrid cloud and multi-cloud adoption is growing significantly.

The trend clearly shows that more and more vendors are looking to deploy less critical workloads in the cloud and run critical database or even apps on premise data centers.

The concept behind this trend is known as edge computing sometimes also called fog computing where most of the local and critical processing is done on the edge instead of sending all the data to the cloud.

The trend of edge computing and the hybrid cloud is clearly identified by public cloud providers such as Azure and the on premise Azure stack — both evidence of a growing trend. Almost all of the Enterprise using the cloud believes in a multi cloud approach; making sure that they are not locked in with just one cloud vendor and have either on premise or have multiple cloud vendors. So, hybrid cloud comes with two options:. In past few years networking also evolved to support cloud use cases.

BYoIP, multitenancy, agile workloads, devops, massive data growth, Machine Learning and advanced visibility requirements have helped networks to evolve. Hybrid cloud networks require special networking because the networks must connect the workloads sitting in different environments which, in turn, in different domains and likely running different protocols.

In the past, many technologies have been available for DCI. All of these technologies were great for solving the challenges associate with older data centers. New data centers which are designed for the latest cloud properties multi tenancy, high speed, application level segregation, etc.

A protocol that has the ability to not only identify a customer network in multi-tenant environment but also the service running inside that customer network which is another layer of segmentation inside customer network. The concept remains same in terms of preserving the service and customer tag and map the right customer and service inside a multi-tenant environment.

The following figure explains how this feature works. In above example, single translation is happening at the edges and still the internal service tag is preserved and delivered right to the cloud. With the rise of hybrid cloud, it is only a matter of time before you will need to connect to cloud.

Technologies such as VPN gateway, direct connect, etc. However, how flexibly you want to connect to cloud using those technology is up to you to design. With the granularity coming to workload level, it is high time that the networks are defined by service level using technologies like QinVNI.

With the growing number of hybrid cloud use cases, the networking for such scenarios will become crucial. Below is an example of a POC which was setup for a well-known cloud provider. Same VLANs has been used for different tenants.

The following section gives details on how one can configure Hybrid cloud networking on Spectrum-based Mellanox platforms.

The network is enclosed within a 1Gb switch and has no routing outside. This network is used to provide storage services. Public network is used to connect Cloud nodes to an external network. Both networks are represented by IP ranges within same subnet with routing to external networks. For our example with 7 Cloud nodes we need 8 IPs in Public network range. Consider a larger range if you are planning to add more servers to the cloud later. In our build we will use range IP range IP allocation will be as follows:.

Virtual LANs (VLANs)

Note: The interface names eth0, eth1, p2p1, etc. Rack Setup Example:. Fuel Node:. Compute and Controller Nodes:. VLAN on all ports. On Mellanox switches, run the following command to enable flow control on the switches on all ports in this example :. Note: Flow control global pause is normally enabled by default on the servers. If it is disabled, run:. If you are running 56GbE, follow this example to set the link between the servers to the switch.

Networks Allocation Example. The example in this post is based on the network allocation defined in this table:. This is the default Fuel network. Management Storage I would like to know what are typical uses of hybrid ports.

I thought it would be usefull for the switch ports in which I connect servers that have a "shared port iLo". Of course, I got into problems because in hybrid ports, it forces tagged packets on default VLAN, which is 1 by default, therefore breaking my idea. I think a trunk port would give exactly what I want, but I thought trunk ports were mostly for ISL inter-switch links.

You typically don't want to use VLAN 1 in a tagged environment, and this might be where some confusion comes from. Incoming traffic is from PC to switch, outgoing traffic is from swtich to PC. They are different traffic flows. Because PC does not support Can you provide more information on " You typically don't want to use VLAN 1 in a tagged environment"? How would you configure your network if you want to use the shared network port for iLO?

It worked OK except that it wouldn't go through the firewall. Essentially, the hybrid port allows everything from the trunk port, plus : it allows more control over the untagged traffic. This makes it very simple to distinguish the uplinks to other switches display port trunk from the downlink ports to end-points which are vlan-aware dis port hybrid.

You could compare it with a tagged link, which is also packet-based vlan processing, but in that case, the switch will read the With a hybrid port it is the same, but you just change the relation : the switch can read e. This sounds complicated, and it is for manual config examples. You could configure for instance a rule so all untagged packets from mac mask ffffff some printer range would be assigned to vlan x the printers vlanso the packets which are tx on an uplink will be tagged with vlan x.

All other untagged packets would not match the rule, so they would be assigned to the PVID vlan configuration. Essentially, when no rules are defined, all traffic is assigned to the PVID just like a trunk interface. When you enable On a traditional port, the untagged port membership changes, so when a second device macB comes online and would be assigned to vlan12 by the radius, it cannot come online since the port is already untagged in vlan Now with the hybrid port, the switch can program the port with the learned first macA and assign it to vlan 11 better than the manual config!

This means when an unmanaged switch with 2 internal hosts like meeting room would be connected to the hybrid port, 2 internal hosts can be authenticated and assigned to their own vlan at the same point in time. You could even have a 3th host which fails authentication, so it would be assigned to the guest vlan on the same port.

HowTo Configure Switch Port Types with Mellanox Onyx

In my case, it is not the communication between two switches, it is the configuration of a server port to allow the use of the shared network port for iLO I know it is not the best practices, but it makes sense in our environment. I didn't find how to have tagged and untagged vlans on the same port using trunk. Turn on suggestions.

There are several models of Spectrum switches, in this example we will use the SN 32 port G Ethernet switches. Before you start, make sure you have the servers installed and powered UP as well as the switches.

We will use the dual port for multi-path solution. Each server will be configured with different VLAN on each port. Create LAG port-channel in trunk mode on ports 31, This link will be used for VRRP communication between switches.

Note : all VLANs are members of trunk ports by default. The trunk allow only tagged traffic, if untagged traffic is needed e. Configure the uplink ports as router ports towards the core switches. Set the IP Address and subnet required on this interface. We design the network to have two VLANs multi-path.

Make sure to install Windows with the latest WinOF-2 driver on the servers. Note : that the second route should have higher metric in the example below. Ping between the servers all to all make sure that traffic reaches the virtual routers and the local router interfaces on the VLANs. Disable a port, verify that the traffic goes via the second port and reach the desired network high availability.

For this example, we will select Profile 5. Note : In the example below, we configure QoS on all ports. It is not needed to do so for the uplink ports, just for the ports that may carry RDMA traffic. For a fair sharing of switch buffer with other traffic classes It is recommended to configure ECN on all other traffic classes as well.

Allocating buffer to priority 3 and mapping it to a lossless pool and allocating buffer to priority 6 and mapping it to a lossy pool:.

Note : the reserved buffer size may be changes according to the port speed and MTU size. PSPath : Microsoft. PSParentPath : Microsoft. Create a Quality of Service QoS policy and tag each type of traffic with the relevant priority.

For testing, you can add another port e. Do not add a Map all untagged traffic to the lossless receive queue. Install-WindowsFeature data-center-bridging. OperationalFlowControl : Priority 3 Enabled.

Open Performance Monitoring tool perfmon and add the following counter sets. Create a synthetic congestion in the network for example, lower the speed of one port to 10Gopen Performance Monitoring perfmon tool, and run the benchmark testing.

Note : PFC counters pause counters are not expected to advance. Run the benchmark test, and verify that the PFC counters are progressing.QinQ with VXLAN is typically used by a service provider who offers multi-tenant layer 2 connectivity between different customer data centers private clouds and also needs to connect those data centers to public cloud providers.

Public clouds often has a mandatory QinQ handoff interface, where the outer tag is for the customer and the inner tag is for the service. Single tag translation adheres to the traditional QinQ service model. The inner C-tag, which represents the service, is transparent to the provider. The public cloud handoff interface is a QinQ trunk where packets on the wire carry both the S-tag and the C-tag.

Single tag translation works with both VLAN-aware bridge mode and traditional bridge mode. However, single tag translation with VLAN-aware bridge mode is more scalable. You configure two switches: one at the service provider edge that faces the customer the switch on the left aboveand one on the public cloud handoff edge the switch on the right above.

An example configuration for single tag translation in traditional bridge mode on a leaf switch is shown below. Double tag translation involves a bridge with double-tagged member interfaces, where a combination of the C-tag and S-tag map to a VNI. You create the configuration only at the edge facing the public cloud.

The double tag is always a cloud connection. The customer-facing edge is either single-tagged or untagged. The configuration in Cumulus Linux uses the outer tag for the customer and the inner tag for the service. For example, consider swp1. It can be either If Double tag translation only works with bridges in traditional mode not VLAN-aware mode. The Linux kernel limits interface names to 15 characters in length. For QinQ interfaces, you can reach this limit easily.

For example, you cannot create an interface called swp50s0. For example:. Double tag translationwhere you map a customer and service to a VNI. An example configuration in VLAN-aware bridge mode looks like this: You configure two switches: one at the service provider edge that faces the customer the switch on the left aboveand one on the public cloud handoff edge the switch on the right above.
