In 2021 where every digital platform is transforming, the new trend, or we can say A SURPRISING BENEFICIAL RELATIONSHIP between Kubernetes-managed containerization and the NVME has been found. The NVMe over Fabrics (NVMe-oF) protocol is a game-changer in storage technology. It has offered the storage infrastructure a pioneering breakthrough that stateful applications needed for a long time to allow Kubernetes-based setups to step up the computing landscape.

To understand the relationship and benefits of NMVE for Kubernetes, you must know WHAT NMVE and Kubernetes are.

Let’s start!

The NVMe Protocol

NMVe stands for “Non-Volatile Memory express,” which is clearly explained as a protocol used in storage procedure/access that allows the CPU to reach out to the solid-state drives (SSDs) memory directly via Peripheral Component Interconnect Express interface. The central role of NVMe is in improving the efficiency of transmitting, storing, and retrieving data. With the help of specific rules and intense technologies, NVMe enables optimum SSD utilization along with increased flexibility and scalability features.

Comprising a target controller and a host-side interface is helpful in Storage Disaggregation – one of the significant benefits of using NVMe. Moreover, you can combine it with Kubernetes to upgrade its operational efficiency. The role of non-volatile memory is in persisting data. The key Performance Features of NVME are:

  • NVMe storage works at a much-advanced speed in comparison to the SATA-based SSDs (a maximum read speed of 2 GB/s)
  • NVMe storage appears much quicker compared to any traditional spinning hard drive.
  • PCIe architecture provides speed and helps in mapping operations in memory, consenting up to 64,000 procedures per queue.
  • NVMe guarantees lower latency, ensuring quick response (2.8 milliseconds)

Kubernetes

“An open-source containerized orchestration platform” enabling automated computer application placement, upgrading, management, and supervision. Formerly designed by Google, it is now managed by the Cloud Native Computing Foundation and supports the methodologies used in cloud services. Kubernetes have multiple uses and purposes. Majorly, it assists in data center outsourcing to public cloud service providers. 

You can use it in web hosting, too. Kubernetes container orchestration brings an extraordinarily flexible and competent form of virtualization, eliminating all the problems associated with hardware maintenance.

Do you want to keep track of your activities and possible changes in container applications? Are you worried about starting and shutting down containers as per the usage? Kubernetes can help you get rid of such worries. For every container management setup, Kubernetes is now identified as the de-facto standard. Why? Due to its capacity to maximize your resource utilization.

The Benefits of Choosing NVMe for a Data Center

  1. Assists diverse form factors and connections
  2. Efficient division and rationalization of data 
  3. Top-performance flash memory
  4. Improved security
  5. Decrease power use 
  6. Efficient storage disaggregation and abstraction 
  7. Streamlined command set

NVMe-oF SUPPORT FOR KUBERNETES

The infusion of NVMe-oF in Kubernetes infrastructures is a groundbreaking step. It allows shared storage available throughout a network at an access latency just like any other locally-attached storage. You can integrate a variety of NVMe-oF flash drives across the standard storage nodes through the use of high-bandwidth network interfaces. These interfaces usually increase the volumes of the available storage to compute-only nodes spread inside Kubernetes containerized workloads. 

Typically, the centrally pooled NVMe SSDs are incorporated inside the Kubernetes infrastructures, with the help of a well-architecture Container Storage Interface standard. With NVMe, you can complete the dynamic volume scaling in Kubernetes transparently. NVMe has the ability to extend the low latency of DAS, making NVMe a practical option to deliver storage for extensible, active, and flexible apps running on Kubernetes.

One of the major advantages of NVMe-oF solutions for Kubernetes or any other cloud-native application that cannot be neglected is disaggregation, maintaining, and scaling local performance. It has been found valuable addition for increasing the functionality and optimizing the operational efficiency of Kubernetes. Moreover, this brilliant feature offers ease of migration. 

And, yes, you will never have to compromise on quality. The standard of performance and availability of services will remain preserved.

Do you know this disaggregation will lower the total ownership cost through better performance efficiencies? What a fantastic tool NVMe-oF is!

That is not all!

The NVMe-oF protocols add to the ease of SAN usage and enhance the performance quality of DAS, making inroads at multiple companies who understand the importance and believe in using flexible, expansive, agile, and high-availability storage for persistent Kubernetes stowage. Improved scaling and availability via clustering are one of the many perks NVMe has to offer. The coupling of NVMe and Kubernetes delivers high-performance, ephemeral storage that works well in excessive workloads for easy processing.

In short, the outcome will be ONLY positive, improving the quality and efficiency of data infrastructures.

  1. The centralization of storage resources
  2. The precise amount of storage and compute assigned for every workload
  3. Cost-efficiency
  4. Delivering the high-performance storage
  5. On-demand flexibility
  6. Low-latency storage of locally-attached solid-state drives
  7. Easy and quick upgrading volume allocation if workload demands extra storage
  8. Workload rebalancing
  9. The flexibility of adding storage resources back to the resource pool through quick down-scaling

Currently, you can find multiple enterprises working to integrate an NVMe-oF plugin for Kubernetes storage to limit the problem of bottling up of running NVMe SSDs on a single, local server.

The disadvantages of NVMe-oF

No matter how important NVMe is for Kubernetes, it would help if you remembered that its integration is equally complicated. The complexity it has in its procedures or difficulty you face while its implementation is a significant disadvantage. It is tiresome, time-consuming, and laborious work.

Another issue is reliability. Systems that use NVMe demand alterations in the respective network layouts as well as Ethernet switch settings that are considered foreign to the universal TCP/IP settings available in most Kubernetes setups. When we talk about dependability, few patented arrays prefer using NVMe-oF with failover but still, never tend to believe in the fact of standard servers and software-defined “everything.”

Final verdict

If we summarize, we can say, the use of NVMe in containerized data centers makes your storage facilities faster and cost-effective that are easy to maintain. It can help you manage a broad range of workloads on Kubernetes. Their merging offers excellent performance in terms of latency.
