MicroVM and Firecracker: Discover Advantages and Disadvantages

During virtualization revolution, physical servers replaced with virtual machines to run multiple different workloads on a single server hardware but virtual machines were still large and needs some resources to run as isolated servers. Virtual machines needs to have their own operating system and applications. Also they needs to manage and configure separately. MicroVM or Micro Virtual Machine offering benefits of two different technologies and Firecracker will help you to implementing MicroVM.

Guest Operating System Upgrade or New Virtual Machine?

Virtual Machine needs guest operating system (OS) to operates same as physical machine. Operating system is a system software and has life cycle same as other software. But what should we do about updating and upgrading guest operating systems in virtual environments. Guest Operating System Life-Cycle Most implemented services don’t need to any new features on operating system, so we should choose guest operating system with long term support. Both Windows and Linux (Some distributions) offering different of channels. You can choose a path that more stable or choose a path for have new features. Update vs Upgrade When you need to newest technologies and features on the latest major version of operating system, you have to do Upgrade. But when you are applying regular patches on operation system, you are doing Update. Keep Update Guest Operating System Operating systems’ vendors releasing patches during operating system life-cycle. Apply patches (Security or others) to keep guest operating system secure and stable as well as your services and business. Even installing service packs or upgrading to a minor version of current guest operating system is an update process and there is no limitation to do it. When We Should Upgrade Guest Operating...

HPE FlexFabric 650FLB Adapter May Cause PSOD on ESXi 6.x

Seems, there is an issue on HPE Blade Servers when a specific adapter is installed on server. If there is any server of the below models in your virtual environment that you should consider to this post: HPE ProLiant BL460c Gen10 Server Blade HPE ProLiant BL460c Gen9 Server Blade HPE ProLiant BL660c Gen9 Server HPE servers running VMware ESXi 6.0, VMware ESXi 6.5 or VMware ESXi 6.7 and configured with an HPE FlexFabric 20Gb 2-port 650FLB Adapter with driver version 12.0.1211.0 (or prior), a “wake NOT set” message is logged in the Vmkernel logs. Then after 20 to 30 days of server run time, a Purple Screen of Death (PSOD) may display a brcmfcoe: lpfc_sli_issue_iocb_wait:10828 message. The following errors are displayed in the VMkernel logs after approximately 50 to 70 days of server run time: 2019-07-20T00:46:10.267Z cpu33:69346)WARNING: brcmfcoe: lpfc_sli_issue_iocb_wait:10828: 0:0330 IOCB wake NOT set, Data x24 x0 2019-07-20T01:10:14.266Z cpu33:69346)WARNING: brcmfcoe: lpfc_sli_issue_iocb_wait:10828: 0:0330 IOCB wake NOT set, Data x24 x0 2019-07-20T02:16:25.801Z cpu33:69346)WARNING: brcmfcoe: lpfc_sli_issue_iocb_wait:10828: 0:0330 IOCB wake NOT set, Data x24 x0 2019-07-20T02:22:26.957Z cpu33:69346)WARNING: brcmfcoe: lpfc_sli_issue_iocb_wait:10828: 0:0330 IOCB wake NOT set, Data x24 x0 2019-07-20T03:26:39.057Z cpu11:69346)WARNING: brcmfcoe: lpfc_sli_issue_iocb_wait:10828: 0:0330 IOCB wake NOT set, Data x24 x0 2019-07-20T04:06:46.158Z cpu11:69346)WARNING: brcmfcoe: lpfc_sli_issue_iocb_wait:10828: 0:0330...

Kubewise, Multi-Platform Desktop Client for Kubernetes

Kubewise is a simple multi-platform desktop client for Kubernetes. In the same way the kubectl command requires only a valid kubeconfig file to run commands against a Kubernetes cluster, Kubewise requires you just to configure one or more valid kubeconfig files to interact with the corresponding Kubernetes clusters. Main features: Support for multiple kubeconfig files. UI-driven interaction with the most frequently used Kubernetes entities. One-click terminal with the proper KUBECONFIG env variable set. Generation of custom kubeconfig files for a given namespace. Highlight sustaniability and security-related data. Requirements Kubewise is a desktop application built with HTML, JavaScript, CSS and Node.js, and it runs on Electron, a framework for building cross platform apps using web technologies. So for running it, basically, all you need is: Any modern macOS, Windows or Linux (Debian-based) OS. kubectl v1.14.0+ installed to access Kubernetes v1.14.0+ clusters. External Links Kubewise

HPE G10 Servers: Best and Optimized Setting for VMware vSphere

Optimizing HPE server configuration is always one of biggest challenges for virtual environments administrators. The administrators always trying to provide best performance by changing configurations on hypervisor, virtual machines or other components or virtual infrastructure. There are best practices which published by server vendors to achieve best performance on their server platform. Server hardware is one most important component in every environment, server provides main power and resource: Computing Resources. Processor and memory and other server’s component made to work almost like as human brain. Some Important Things! Human brain needs consumes about 20 percent of the body’s energy. Consume more energy is equal to more heat in human body. Server components needs energy and cooling, like human body. Energy and cooling needs money. So there is a challenge to keep balance between performance and cost of services in any IT environments. What’s Important About Server Hardware? In fact, processors and cooling system consume most power which provided by power modules. Don’t think about single server, think about hundreds of servers and thousands processors, thousand x 200W! (At least). Best performance has more cost for any environment also needs more maintenance. What’s Best Practices? Best practices are depended to workload...

Using Network Partitioning (NPAR) in VMware ESXi

Data Center design is changing year by year, before virtualization all servers was physical and data centers were full of devices and cables. Virtualization helped to make data centers smaller and consolidate different workloads in same hardware. Hardware technologies are also helping to achieve this goal. Network Partitioning (NPAR) is one of hardware technologies which helping to reduce cabling, switch devices and use all I/O capacity in data centers. What’s Network Partitioning (NPAR)? NPAR is an operating system and switch agnostic technology that allows customers to reduce the number of I/O adapters required to support different application workloads. Traditional best practices require separate LAN or SAN connections for different aspects of application workloads. Converged Network Adapters already support widely used SAN protocols like Fibre Channel over Ethernet (FCoE) and iSCSI, administrators can already reduce the number of adapters needed for separate protocols, including separate Fibre Channel and Ethernet adapters. With NPAR, these adapters can now partition their network bandwidth further into multiple virtual connections, making one dual-port adapter appear as eight adapters to the operating system for use by the applications. This greatly simplifies the physical connectivity to the server, reduces implementation time, and lowers the acquisition cost of the...
