VMware Hot-Add RAM feature isn’t new, but somehow we haven’t covered it much just yet. So this post will explain What is VMware Hot-Add RAM and How to use it. The Hot-Add RAM goes hand in hand with Hot-Add CPU, but we’ll cover that in a separate post. Using hot-add/hot-plug you can add memory resources to […]
What are Open VM Tools and How to use them?
I had this question recently on Open VM Tools (OVT) and I thought that a blog post about What are Open VM Tools would be a good way to reply. Since several years VMware supports Open VM tools as an Open Source initiative to allow VMware to ease the task of creating and maintaining hundreds of […]
What is VMware Snapshot?
Another post today to our “definition” category, which starts to gain some momentum. The idea behind is to give a basic explanation on VMware technologies and how things work. We always thought that writing technical posts is enough to be successful as a blogger, but we were wrong. Our recent non-technical post What is The Difference […]
What is STUN Server?
A while back we wrote post about WebRTC technology. Today, we’ll continue to remind some basics about WebRTC and learn few things about STUN. Web Real-Time Communication (RTC) is an open standard for embedding real-time multimedia communications directly to a web browser, via VP8 video codec, which is free. WebRTC uses a server called Web Conferencing […]
What is The Difference between VMware vSphere, ESXi and vCenter
This post is not a deep dive, and it’s not even much technical. We’ll focus on VMware terminology. It’ is just a quick post for folks unsure about the differences between the base VMware products. Almost anyone knows ESXi, but the difference between vSphere and vCenter? People are often confused and unsure, but those answers […]
What is VMware vMotion?
What is VMware vMotion? It is THE feature, the function, which “hooked” thousands of millions IT guys on the plane for using VMware for their IT infrastructure. It is kind of a holy grail of virtualization where a running VM moves to another host without interruption of service (of with just a few pings lost). I still […]
What is VMware Cluster?
VMware terminology differs from other IT terminologies. It is specifically focused on VMware virtualization and has completely different meaning than terminologies for other IT vendors and systems. VMware beginners should not be discouraged to learn this technology. You don’t have to manage thousands cloud-scale enterprise infrastructure to learn the basics of VMware vSphere architecture which […]
What is VMware vSphere Hypervisor?
VMware virtualization is based on a bare-metal hypervisor platform and the base product ESXi is also called VMware vSphere Hypervisor. Those days there is many hypervisors out there, but the more ancient and more adopted is the one from VMware. Microsoft’s Hyper-V hypervisor is another example of hypervisor used. Today we’ll focus on What is VMware […]
What is VMware Storage DRS (SDRS)?
Today we’ll get more details about another VMware technology called Storage DRS (SDRS). Storage DRS allows you to manage the aggregated resources of a datastore cluster, which means that you can balance a space and I/O load between different datastores within a datastore cluster. Also, SDRS manages the initial placement of virtual disks based on space […]
What is VMware Orchestrated Restart?
VMware Orchestrated Restart has been introduced in vSphere 6.5. This built-in feature allows multi-tier VMs to be restarted with the right order in case of host failure. Those VMs can be placed on different hosts, either automatically via DRS or manually, via vMotion. VMware orchestrated restart is not referring to single host VM start priority […]
