Kubernetes on VMs vs. Bare Metal: Comparison of Performance

This article presents empirical performance data of Kubernetes running stateful and stateless applications on VMs (SMTX Kubernetes Services, referred to as SKS) and bare-metal servers. Overall, the results demonstrate that SKS shows performance ranging from 82% to 96% of bare-metal-based Kubernetes, indicating that VM-based Kubernetes can effectively meet the requirements of the majority of containerized applications in production environments.

Preserving Data Integrity with Temporary Replica Strategy of SmartX HCI

Hyperconvergence software (HCI) usually leverages multiple replicas to provide redundant protection for storage data. However, the mainstream multi-replica strategy still cannot avoid the risk of data loss during the replica recovery process. To address this challenge, SmartX HCI 5.1 introduces the innovative “temporary replica” strategy. This strategy prevents the degradation of replica numbers during the replica restoration process, enhances the security of storage data, and strengthens the stability of core business services.

Network I/O Virtualization in SmartX HCI: Virtual NIC, PCI Pass-through and SR-IOV Pass-through

To facilitate users in leveraging network virtualization, SmartX has introduced PCI NIC pass-through capability in SMTX OS 5.1. This feature, combined with the existing SR-IOV pass-through and virtual NIC capabilities supported in previous versions, enables SMTX OS 5.1 to comprehensively support ELF (SmartX native hypervisor) users in harnessing the benefits of network I/O virtualization. Users can select the most suitable options based on their requirements for network performance, network isolation, and cost efficiency in various use cases, including futures trading, HPC, and more.

GPU Passthrough & vGPU: Using GPU Application in Virtualization with SMTX OS 5.1

To maximize GPU utilization, many enterprises choose to virtualize GPUs or use them in virtualization (including HCI). But how can we fully leverage GPU’s capabilities on virtualized IT infrastructure? And how can we provide stable, high-performance storage as well as compute resources for various GPU applications with an integrated IT infrastructure? To help users address these challenges, SmartX has introduced GPU passthrough and vGPU features in the upgraded HCI software SMTX OS 5.1.

Eliminate Virtual Network Blind Spots with SmartX Network Visualization

As cloud computing has advanced, technologies like network virtualization have made it easier for administrators to centrally manage networks. However, this has also led to increased complexity in network traffic within the cloud. Traditional methods and tools for diagnosing data traffic face challenges when it comes to visualizing and analyzing "east-west traffic" on virtual networks. This creates network blind spots and further complicates issue locating. 

Reuse Existing Devices with SmartX HCI: 4 Customers Achieve IT Infra Transformation at a Lower Cost

When businesses upgrade their IT infrastructure to hyperconvergence (HCI), they often hope to cut costs and improve resource utilization by repurposing existing hardware devices like servers. However, this can be challenging in practice as the selected HCI product may not be compatible with the existing hardware or may only be available in a packaged hardware form. Another challenge is managing both legacy and new hardware devices in a unified manner.

Exploring the Architecture of ZBS – How NVMe-oF Boosts Storage Performance

In the article “Exploring the Architecture of ZBS – SmartX Distributed Block Storage”, we explained the communication between the Access (data access component) and the Meta (management component) in ZBS when I/O occurs. This is the latter part of the I/O path.
In this article, we will focus on the former part, i.e., the access protocol layer for communication between the computation side and ZBS. We will first evaluate different access protocols and explain the design and implementation of NVMe-oF in ZBS, and then provide test data of ZBS performance based on different access protocols.

Three Performance Comparisons Disclose Why You Should Choose SmartX HCI as a VMware Alternative

Users of VMware vSAN may experience issues such as high latency, cache breakdown, and performance degradation. While many factors can contribute to these problems, the design of storage architecture (e.g., I/O path and cache) plays a critical role. If you are troubled in the same way and seeking to upgrade your legacy IT infrastructure, here are some articles that can help you understand how vSAN works and how SmartX, with modernized HCI, can improve cluster performance and make IT simple.

Automatic Data Recovery Policy: Stabilizing Application Performance While Accelerating Data Recovery

As far as we know, the ultimate performance of a distributed storage cluster is physically decided by its hardware configuration. However, if unexpectable problems such as hard disk and node failures happen and trigger the data recovery during business rush hours, users may find themselves facing a hard choice: which should be the priority, accelerating data recovery or optimizing business performance?

Unprecedented Scalability: Explore SmartX HCI’s Flexible Scale-out Options

Due to the limitation of centralized storage, it’s usually difficult and risky for the IT infrastructure based on legacy virtualization architecture to scale out. Hyperconvergence, on the contrary, enables flexible expansion and on-demand investment as it streamlines the architecture by converging compute virtualization and distributed storage. This is one of the most critical reasons why more enterprises are turning to HCI.

How to achieve seamless and zero-downtime upgrade of IT infrastructure software and hardware?

As anyone who has worked as an IT infrastructure administrator knows, upgrades of software, hardware, and patches can always be nightmares. This is because IT infrastructure upgrades may incur unexpected problems and cause system outages, which can be a catastrophe to critical business — with a massive loss not limited to revenue and reputation. So most companies would avoid upgrading their IT infrastructure too often. 

SmartX ZBS CSI Driver Officially Merged on K8s Drivers List

SmartX announced that the Container Storage Interface (CSI) driver of its distributed storage platform SMTX ZBS has been added on Kubernetes CSI production drivers list so as to integrate block storage system with Kubernetes containerized environment. Enterprise users can not only leverage SMTX ZBS to build private cloud and hyper-converged infrastructure system, but also introduce persistent storage into stateful applications on Kubernetes.
