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.

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.

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.

Creating ESXi VMs on the Windows based NFS share

Many words were said about NFS (Network File System), but what exactly NFS can give us? In general, NFS used as the ISO library or just simple network file share with easy access from any Windows or Linux based machine. However, starts from NFS 3.0 protocol can give us the good performance and can be as the shared storage for ESXi or any Linux based Hypervisors. In this article, I will create the NFS share on the Windows Server 2016 and then mount NFS share on the ESXi 6.5 and will create the VM on it.

vSphere Upgrade Options

When it comes time for your vSphere upgrade there are many different approaches to how you perform the upgrades on your ESXi hosts.   An administrator who looks after a small cluster may update one way, whereas an administrator who looks after an enterprise with 1000s of hosts may opt to go another.  Also, depending on how your environment is deployed you might want to choose one method over another.  Factors such as a whether or not your hosts are managed by a vCenter server, whether or not they are members of a cluster – these things all impact the methods in which you chose to update to the latest version of ESXi.  Certainly, some methods are much more simplistic than others to perform, some offer more advantages when upgrading at scale, and some are more prone to user error – let’s take a look at each method of upgrading our hosts below and discuss the benefits and drawbacks of each…

Accessing esxcli through PowerCLI

Picture this – you are working away developing a PowerCLI script that is performing multiple actions – you have it just about complete when you come to a roadblock.  After frantically googling around you find out that this one task you are trying to perform simply cannot be done through PowerShell, yet you know it exists within the local ESXi esxcli command namespace!  This has happened multiple times to me and thankfully, there is a way to access ESXi’s esxcli command namespace without having to leave the comforts of the PowerShell Console. Chances are that if you have been working at all with ESXi you are familiar with the esxcli command – but for those that aren’t let’s take a quick look at what exactly it does.

Convert a physical Linux server to VMware VM

When you implement a virtual infrastructure, you may want to convert your physical servers to virtual to improve your datacenter consolidation. In this topic, we will see how to convert a physical Linux server to a VMware VM. To make this conversion, I used VMware vCenter Converter Standalone. To host VMware vCenter Converter Standalone, you need a physical or virtual machine based on Windows Server. Usually, when I run this tool, I use a virtual machine. Then run the executable to process the product installation.
