Learn when to use Raw Device Mapping (RDM) in VMware vSphere, how to configure it, and the trade-offs involved in direct LUN access.

  Sometimes, you badly need to provide your VMware VMs with more RAM or vCPUs without shutting them down. True, there’s a trick allowing you to do that – CPU Hot-Plug and Memory Hot-Add. In this article, I’ll discuss both these features and how to use them in different environments. Why do I write an article about Hot-Plug and Hot-Add in 2018 even though they were introduced back in ESXi 4.0? You see, there are very few in-depth studies of how Hot-Add and Hot-Plug work in different environments for some reasons. Sure, you can find a bunch of good articles about how you enable those features, why you need them, and when you may just want to leave them disabled (yes, they are disabled by default). There were some studies held for Windows guest OS family, but there is very few known about how Hot-Add/Hot-Plug work in Linux. Well, I hope to fill that gap with this article.

If you are new to VMware or just starting out in the tech, you may feel a bit confused about products naming. Well, at least I was. There are tons of products in the suite so many have a hard time grasping how all those things come together. For instance, it may be hard for a beginner to tell apart ESXi and vSphere. What should you do? Well, nothing special, you know. Google. Ask fellow admins. Look through forums. Read books. Well, my post is not here to bring you from the very beginning to finish. It’s rather a long process, and you need to pay your dues sometimes. Honestly, I got some knowledge only through fixing things that I had messed up. This post covers some questions that popped out in my head when I was only starting. And, my case is not unique. So, let’s start with VMware!

VMware ESXi is the industry-leading hypervisor that is installed directly on a physical server. It is a reliable and secure solution with a tiny hardware footprint. At the same time, ESXi architecture is easy in management, patching, and updating. Recently, Mellanox has released iSER 1.0.0.1, the stable iSER driver build for ESXi. iSER is an iSCSI extension for RDMA that enables the direct data transfer out and into SCSI memory without any intermediate data copies. Here, we study the driver stability and performance to understand how the protocol streamlines ESXi environments.
