The IOChain is a group of functions that provides connectivity between virtual ports and the virtual switch. It also provides the capability to insert functions into the network data-path regardless of the switch type used i.e. Standard Switch (vSS) or Distributed Switch (vDS). A virtual port has two IOChains based on the direction i.e. to … Continue reading Uncovering virtual networking Part-9: IOChain Framework

AppInfo plugin in VMware Tools 11 enables the collection of the running application processes within a Guest OS and publishes that information to VM guestInfo Property called as guestinfo.appinfo. For each application running inside the guest, the name and version information is captured and published by the plugin. The appInfo plugin collects the information in every 30 minutes by … Continue reading AppInfo plugin in VMware Tools 11.x
In this article, we will explore NSX-T 3.0 architecture components and try to understand the key concepts behind each of them. NSX-T provides the complete set of networking and security services such as switching, routing, fire walling, load balancing, QoS, IDS in software. These services can be programmatically assembled in arbitrary combinations to produce unique, … Continue reading NSX-T 3 Components
Although vRealize Suite is made up of several products, it is a single solution with a single license. All the components of a vRealize Suite edition are licensed as a single entity.
This will be the last post in this series. In this post, we are going to discuss hypervisor swapping as next method after compression. ESXi employs hypervisor swapping to reclaim memory, if other memory reclamation techniques like ballooning, transparent page sharing, and memory compression are not sufficient to reclaim memory. Transparent Page Sharing (TPS) speed … Continue reading VMware vSphere 7.x Memory Reclamation-Part 6: Hypervisor Swapping
In this post, we are going to discuss about memory compression cache technique used by ESXi host. In previous posts we have already discussed TPS and ballooning. So compression is the next technique in order that gets initialized when ESXi host is under memory contention. ESXi provides a memory compression cache to improve virtual machine … Continue reading VMware vSphere 7.x Memory Reclamation-Part 5: Memory Compression Cache
