After TPS in previous post, we will explore Ballooning reclamation technique in this post. Basically I am just following the order in which these techniques are initialized. Ballooning is a process where the hypervisor reclaims memory back from the virtual machine. Also if ballooning is started on an ESXi host, it indicates the beginning of … Continue reading VMware vSphere 7.x Memory Reclamation-Part 4: Ballooning
Previously in Part-1:Basics and Part 2: MinFree, we discussed about memory reclamation, need for memory reclamation, ESXi memory states, sliding scale method for calculating MemMinFreePct value. In this post, we will explore sharing memory pages with memory reclamation technique called as Transparent Page Sharing or TPS. On an ESXi host, many workloads present opportunities for sharing … Continue reading VMware vSphere 7.x Memory Reclamation-Part 3: Transparent Page Sharing (TPS)
So here we are with another post in this series. In previous post we discussed basics of memory virtualization concepts and the need for memory reclamation. In this post we will explore ESXi host memory states, sliding scale method of calculating Mem.MemMinFreePct. As discussed in previous post, multiple VMs that run on ESXi host, share … Continue reading VMware vSphere 7.x Memory Reclamation-Part 2: Mem.MemMinFreePct
Welcome everyone to this series on memory reclamation techniques in vSphere 7.x. This will be one more long series of posts after my previous series on uncovering virtual networking. In this series, we will try to understand the memory virtualization basics, memory reclamation techniques in vSphere (Specifically ESXi hosts), ESXi host Memory states, and sliding … Continue reading VMware vSphere 7.x Memory Reclamation-Part 1: Basics
I was working on some test configuration in my lab and noticed the update pop-up. So just checked it out on my vCenter Server 7.0 update planner for more details about this patch. Out of curiosity, checked the release notes for the same in order to understand details about this patch since it is marked … Continue reading VMware vCenter Server 7.0.0a Update
In previous post on Network failure detection, we started with the Teaming and Failover policies. We are going to explore load balancing algorithms in virtual networking in this post. This one is going to be the longest post I have written until now I guess 🙂 We have two types of switches, standard (vSS) and … Continue reading Uncovering virtual networking Part-8: Load balancing Algorithms
Here we are with yet another post in this series on uncovering virtual networking. In previous post we discussed, Traffic Shaping. In this post, I will try to dive into network failure detection (NFD) policy options available in vSphere (Specifically ESXi 🙂 ). By the way, starting with this post, we are entering into Teaming … Continue reading Uncovering virtual networking Part-7: Network Failure Detection Policy
