Storage Controllers in VMware vSphere
Storage controllers are virtual environment tools essential for locating and accessing both block-based devices and SCSI devices. Storage controllers in VMware vSphere virtualization platform can operate with different storage controllers, varying in types, purposes, and usages. A wide range of functional capacities allows you to establish storage controller compatibility, choose configurations, and process SCSI emulation and paravirtualization. Use a storage controller as best suited for your preferred OS!

Changing the hardware resources on a running VM

Each virtual machine (VM) is a collection of resources provided by the infrastructure layer, usually organized in a pool of resources and assigned dynamically (or in some case statically) to each VM. VMs “see” a subset of physical resources in a form of virtual hardware components defined usually by the certain minimum elements. Adding hardware components can be useful in some cases, or they can be necessary for performing some basic operations, like, for example, installing the guest OS where a video driver, a keyboard and a mouse device are needed to use the remote console. That is why you should be aware of which hardware resources can be hot-add and which hot-remove.

StarWind Virtual SAN for vSphere Linux Software RAID configuration

StarWind & VMware vSphere users get unrestricted StarWind Virtual SAN features, storage capacity, and outstanding cost-efficiency. Using StarWind VSAN, the process of deploying VMs, providing fault-tolerant storage, connecting it to hypervisor, and creating highly available VMs becomes a “piece o’ cake!”. But what about software RAID configuration? How not to get lost in a variety of choices between the different RAID levels?

Migrate On-Premises Virtual Machines to AWS

Migration of virtual machines is an important feature of virtualization technology that allows applications to move transparently along with their runtime environments between physical machines. AWS Server Migration Service (SMS) allows the migration of one or multiple on-premises virtual machines to AWS in an easy way from a single pane of glass. Plan, automate, and track step-by-step replication of running server volumes with just one tool — the AWS console!

StarWind Virtual SAN for vSphere

In this article, I discuss what StarWind Virtual SAN for vSphere is and how to set it up on the hardware RAID. StarWind VSAN for vSphere is a Software-Defined Storage solution that is designed specifically for vSphere environments. It comes as a preconfigured VM template, so just a couple of quick steps are needed to start running your vSphere environment on StarWind VSAN: download the solution, deploy it, and “play”. Here, I want to share some tips and tricks on working with VSAN for vSphere.

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.

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.

VMware Skyline – Advanced Technical Support for Large Virtualized Environments

For some reason, VMware Skyline is not common knowledge for VMware vSphere admins and VMware products users on the whole. Skyline is VMware proactive support technology allowing to provide advanced technical support for VMware vSphere products (including vSAN 6.6 and later) and VMware NSX. Soon, some other products will be supported. But wait, what is this service actually for? To make that thing clear for everyone, I’d like to shed light on VMware Skyline in this article.

Secure your data for good with Challenge Handshake Authentication Protocol

Today we will look at one of them – Challenge Handshake Authentication Protocol or CHAP. Before we start, let me tell you a few words about CHAP. Challenge Handshake Authentication Protocol (CHAP) is a network login protocol that uses a challenge-response mechanism. You can use CHAP authentication to restrict iSCSI access to volumes and snapshots to hosts that supply the correct account name and password (or “secret”) combination. Using CHAP authentication can facilitate management of access controls because it restricts the access through account names and passwords, instead of IP addresses or iSCSI initiator names.

Generating a Support Bundle: How to Retrieve Virtual Infrastructure Logs from VMware vCenter and ESXi Servers

One day, any VMware administrator may require the so-called “support bundle” which contains log-files, diagnostic information, and performance metrics. Taken together, these parameters allow troubleshooting VMware vSphere. The bundle provides VMware GSS (Global Support Services) the insight into virtualized environment configuration which allows them to resolve issues, when a client submits a support ticket with this bundle attached.
