With the Diamanti platform, even though Ingress controllers are recommended, applications can be architected without going through an Ingress controller. Each endpoint can optionally be annotated to use a specific performance tier that sets minimum guarantees and maximum allowed throughput (similar to Kubernetes Requests and Limits ) for network and storage I/O. This eliminates the noisy neighbor problem. Quality of Service (QoS)ĭiamanti provides guaranteed SLAs based on hardware-level QoS for each virtual interface.

Each pod has its own unique MAC address allowing customers to use traditional network inspection at the TOR switch and track individual packets back to the originating pod. L2 networks allow pods to be part of the corporate network and can be configured to directly communicate with the rest of the network. Pods are first-class citizens in the corporate network Kubernetes API, Diamanti API, WebUI, and administrative shell access) and storage traffic are segregated from container traffic for performance and security reasons. Traffic Isolationĭiamanti nodes have physically separate interfaces for management, storage, and container traffic. This fits very well with traditional network architecture. Network architects have the option to configure those VLANs to be private within the local network of the cluster or exposed to the whole corporate network, and even though not recommended, it can be theoretically exposed to the public internet. As in traditional networking configuration, the network architect can carve out VLANs and IP address ranges, and configure them on the switch to which the Diamanti cluster connects to. Each Diamanti node is connected to a TOR (Top of Rack) switch, and pods on different nodes communicate with each other via this TOR switch. From Diamanti’s perspective, these IP addresses are ranges of reserved IP addresses that are part of your corporate network.ĭiamanti L2 networking provides many unique advantages: VLAN-based segmentationĭiamanti’s hardware-defined network uses VLAN-based segmentation for isolating the traffic between different tenant pods. Diamanti allows users to create multiple Diamanti networks by assigning an IP to each VNIC, essentially the pod, out of a pool of IPs. Each pod can be part of the corporate network and can be accessed directly within the corporate network. IT administrators can choose to plumb more than one VNIC to a pod.ĭiamanti L2 networking brings traditional and familiar networking approaches to containers, making it very simple for organizations to move a workload to a container architecture.
Diamanti’s Ultima SmartNIC comes with a 40G (4x10G QFSP) interface, out of which 20G is reserved for Diamanti storage traffic and 20G is reserved for pod data traffic.ĭiamanti Ultima SmartNIC bypasses the host networking stack and uses SR-IOV virtual functions to plumb a VNIC (Virtual Network Interface) directly to a pod’s network namespace on its local eth0 interface. Figure 1: Diamanti’s unique networking architectureĭiamanti provides two separate networking planes for storage and pod traffic which are physically isolated from the host network. This improves overall efficiency and reduces the server footprint, which in turn can provide 80% total cost of ownership (TCO) savings. By offloading storage and network traffic, Diamanti Ultima SmartNIC drives 95% host utilization, making more processing power available for actual applications. L2 networking model with hardware acceleration and VLAN-based segmentationĭiamanti accelerates networking with its Ultima I/O offload cards which virtualize networking and storage at the hardware layer, freeing up the host from networking and storage functions. In this blog, we’ll deep dive further into Diamanti’s unique Layer 2 (L2) and Layer 3 (元) networking models. In Part 1 of this blog, we discussed at a high-level how Diamanti helps solve many shortcomings found in most of the common Container Network Interface (CNI) plugins available for Kubernetes.
