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.

Set up your Hyper-V environment to boot VMs in the correct order every time, keeping dependent services happy and downtime minimal.

Today, I’ll talk about a thing that any sysadmin running Hyper-V VMs does (or still dreams about) while managing infrastructure resources: hot modifying assigned to VM memory amount. I’ll discuss not only the feature itself but also how it works on different OS and its impact on the environment stability. All of us keep an eye on resource consumption within our environments. If a VM needs extra RAM to have the job done, we provide it with some, right? And, we usually run many VMs on our servers each with own purpose and configuration. That’s, actually, why changing the amount of assigned to a VM memory without rebooting it may come in handy. Also, many guys run some parts of their environments on Windows while having other parts run on something from Linux family. Looks pretty hectic in terms of management, doesn’t it?

Hyperconvergence has dramatically transformed data center landscape over the past few years. New technologies are being developed, good old ones are being improved… We live in exciting times! And as data centers are becoming more reliable and powerful, it is important to get more out of the hardware in use: nobody likes to leave money on the table! Intel, Mellanox and StarWind have teamed up to develop a Hyper-V highly available cluster where you’ll get awesome performance without compromising ease of manageability of the environment. This article discusses the measurements in brief, showcasing the recent results.
