VMware vSphere 7.x Memory Reclamation-Part 3: Transparent Page Sharing (TPS)

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)

VMware vSphere 7.x Memory Reclamation-Part 2: Mem.MemMinFreePct

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

VMware vSphere 7.x Memory Reclamation-Part 1: Basics

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

Uncovering virtual networking Part-8: Load balancing Algorithms

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

Uncovering virtual networking Part-7: Network Failure Detection Policy

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

Uncovering virtual networking Part-6: Traffic Shaping

In previous post, we discussed about Security policies, MAC change and Forged transmit. With that covered, in this post, we will explore next switch policy which is Traffic Shaping policy. Traffic shaping policy allows ESXi host to shape the network traffic in both directions, Egress(Outbound) and Ingress (Inbound)***. Ok, what does it mean by 'shape … Continue reading Uncovering virtual networking Part-6: Traffic Shaping
