StarWind SAN & NAS as Hardened Repository for Veeam B&R

Ransomware is a global threat, and the best answer to it is to have immutable backups. Veeam’s Hardened Backup Repository is an efficient and cost-effective solution, but it can require some effort to configure. StarWind simplifies the process, allowing you to easily set up an immutable backup repository with just a few clicks.

ESXi is free… So why would you buy an ESXi anyway?

Most admins know that VMware offers Free and Evaluation versions of their hypervisor. However, there are still some nuances that explain why people would actually buy ESXi.

How to Convert Hyper-V to VMware VM

VMware vSphere and Microsoft Hyper-V are among the most popular type 1 enterprise hypervisors. However, their VM formats are incompatible, and it is not uncommon for users to look for an easy way to migrate a virtual machine from one hypervisor to another.

Access Rights in StarWind Virtual SAN® How it works

This blog article discusses Access Rights feature and its implementation in VSAN from StarWind environment. Access Rights allows you to segregate the storage between multiple clusters or hypervisors. You can configure the feature with StarWind Management Console, and, in this article, I’ll teach you how that can be done.

In-Place Upgrade Domain Controllers from Windows Server 2016 to Windows Server 2019

Windows Server 2019 should be available in barely two months. So, first migration will start shortly after. From experience, I know that the first feature customers ask for migrating is Active Directory. Therefore, I wanted to try In-Place Upgrade, which has been improved in Windows Server 2019. To try this feature, I upgraded a forest that is handled by two domain controllers running on Windows Server 2016. It was not a “click and fun” process, but Microsoft has really improved In-Place Upgrade. Let’s take a look at how to migrate Windows Server 2016 DC to 2019.

Persistent memory in VMware vSphere 6.7: what is it & how fast is it?

Persistent Memory (PMEM) support is introduced in the recently released VMware vSphere 6.7. This new non-volatile memory type covers the gap in performance between the random-access memory (RAM) and Flash/SSD. But, is PMEM really that fast? In this article, I take a closer look at what persistent memory is and its performance.

RDM disks for VMware vSphere VMs: how & why to create them

Sometimes, you need your VMs to access a LUN directly over iSCSI. Direct access comes in handy when you, let’s say, run SAN/NAS-aware applications on vSphere VMs, or if you’re going to deploy some hardware-specific SCSI commands. Also, with direct access, physical-to-virtual conversion becomes possible without migrating a massive LUN to VMDK. Whatever. To enable your VMs to talk directly to LUN, you need a raw device mapping file. Recently, I created vSphere VMs with such disks. Well, apparently, this case is not unique, so I decided to share my experience in today’s article.

Make a disaster recovery plan with Veeam Backup & Replication 9.5

Veeam Backup and Replication is a backup and replication product. The backup part ensures your workloads are protected against bad manipulation, ransomware or disaster. It enables to restore the data in case of loss. The replication part ensures that your workloads can quickly start again in another datacenter in case of sinister in the first one. Products such as Microsoft Hyper-V or VMware vSphere can also handle this task. In this topic, I will show you how to leverage Veeam Backup and Replication to make a disaster recovery plan. The same steps can be applied to Hyper-V or VMware but in this topic, I will take VMware as example.

VMware OS Optimization Tool (OSOT) – Free tool for Virtual and Physical systems

VMware OS Optimization Tool (OSOT) is a free tool provided by VMware Labs website. A website which is well known for the “Flings”, which are free utilities which helps IT admins in their day-to-day administration tasks. The utility uses templates which provides an easy way to disable windows services which aren’t mostly necessary. By disabling unnecessary services you’re basically make the system run more “light” so you’re saving resources which can be used for other programs.

Security threats in a virtual environment

Security is typically a hot-topic due also to several regulations and compliant rules and laws. But more important, a security breach can have huge collateral effects, also if no data has been stoled, or compromised. But, for example, a “simple” DoS attack that makes a service not available can have a bad effect on the reputation of a B2C company. This post will try to give an idea of some possible security threads in a virtual environment based on VMware vSphere (but several concepts are quite general also for other virtualization platforms) and some possible approaches to minimize the effect or prevent the attacks.

Working with Azure Container Instances

ACI lets you create Linux or Windows Containers without the need to deploy a Container host, so in other words, ACI is serverless, and it works like a charm! So in this article, I will describe how to create a simple Container using Azure Container Instances (ACI). In the first part, I will describe ACI using the Azure Portal and the command line, and in the second part, I will describe Azure Container Registry.

Using the AWS cli to backup to AWS from a remote server

I run a few small non-AWS hosted VM’s for things like my blog and email. These VM’s are typically run on LAMP stack style environments with a few customizations for monitoring and reporting that I like to run on the servers. Because of the hosted nature of the servers, I will admit that I did not always back up the content as often as I should.

Hybrid Cloud Extension – Part 2

If you ever worked with vSphere, you definitely used at least one of those. However, in HCX they are used with Secure Proxy. All migration traffic is proxied via HCX WAN Interconnect appliance (WAN-IX). Deployed WAN-IX simulates new ESXi host under local vCenter. You can actually see it in the Web Client inventory. From the point of view of vCenter and other ESXi host the WAN-IX is just another regular host.
