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.
In this post, we will discuss about using single or multiple vNICS on a VM and vmkernel networking CPU threads to optimize transmission rate of VM traffic. We can create a VM with single vNIC or multiple vNICs depending upon operational requirements. Using multiple vNICS on a VM could be for different types of traffic … Continue reading How to optimize Virtual machine vNIC transmit (Tx) performance?
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
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)
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
