A2U, an IGEL Platinum Partner, recently experienced a situation where one of its large, regional healthcare clients was hit by a cyberattack. “Essentially, malware entered the client’s network via a computer and began replicating like wildfire,” recalls A2U Vice President of Sales, Robert Hammond.
During the cyberattack, a few hundred of the hospital’s PCs were affected. Among those were 30 endpoints within the finance department that the healthcare organization deemed mission critical due to the volume of daily transactions between patients, insurance companies, and state and county agencies for services rendered. “It was very painful from a business standpoint not to be able to conduct billing and receiving, not to mention payroll,” said Hammond.
Prior to this particular incident, A2U had received demo units of the IGEL UD Pocket, a revolutionary micro thin client that can transform x86-compatible PCs and laptops into IGEL OS-powered desktops.
“We had been having a discussion with this client about re-imaging their PCs, but their primary concern was maintaining the integrity of the data that was already on the hardware,” continued Hammond. “HIPAA and other regulations meant that they needed to preserve the data and keep it secure, and we thought that the IGEL UD Pocket could be the answer to this problem. We didn’t see why it wouldn’t work, but we needed to test our theory.”
When the malware attack hit, that opportunity came sooner, rather than later for A2U. “We plugged the UD Pocket into one of the affected machines and were able to bypass the local hard drive, installing the Linux-based IGEL OS on the system without impacting existing data,” said Hammond. “It was like we had created a ‘Linux bubble’ that protected the machine, yet created an environment that allowed end users to quickly return to productivity.”
Working with the hospital’s IT team, it only took a few hours for A2U to get the entire finance department back online. “They were able to start billing the very next day,” added Hammond.
This eBook explains how to identify problems with vSphere and how to solve them. Before we begin, we need to start off with an introduction to a few things that will make life easier. We’ll start with a troubleshooting methodology and how to gather logs. After that, we’ll break this eBook into the following sections: Installation, Virtual Machines, Networking, Storage, vCenter/ESXi and Clustering.
ESXi and vSphere problems arise from many different places, but they generally fall into one of these categories: Hardware issues, Resource contention, Network attacks, Software bugs, and Configuration problems.
A typical troubleshooting process contains several tasks: 1. Define the problem and gather information. 2. Identify what is causing the problem. 3. Fix the problem, implement a fix.
One of the first things you should try to do when experiencing a problem with a host, is try to reproduce the issue. If you can find a way to reproduce it, you have a great way to validate that the issue is resolved when you do fix it. It can be helpful as well to take a benchmark of your systems before they are implemented into a production environment. If you know HOW they should be running, it’s easier to pinpoint a problem.
You should decide if it’s best to work from a “Top Down” or “Bottom Up” approach to determine the root cause. Guest OS Level issues typically cause a large amount of problems. Let’s face it, some of the applications we use are not perfect. They get the job done but they utilize a lot of memory doing it.
In terms of virtual machine level issues, is it possible that you could have a limit or share value that’s misconfigured? At the ESXi Host Level, you could need additional resources. It’s hard to believe sometimes, but you might need another host to help with load!
Once you have identified the root cause, you should assess the impact of the problem on your day to day operations. When and what type of fix should you implement? A short-term one or a long-term solution? Assess the impact of your solution on daily operations. Short-term solution: Implement a quick workaround. Long-term solution: Reconfiguration of a virtual machine or host.
Now that the basics have been covered, download the eBook to discover how to put this theory into practice!
If you’re here to gather some of the best practices surrounding vSphere, you’ve come to the right place! Mastering vSphere: Best Practices, Optimizing Configurations & More, the free eBook authored by me, Ryan Birk, is the product of many years working with vSphere as well as teaching others in a professional capacity. In my extensive career as a VMware consultant and teacher (I’m a VMware Certified Instructor) I have worked with people of all competence levels and been asked hundreds - if not thousands - of questions on vSphere. I was approached to write this eBook to put that experience to use to help people currently working with vSphere step up their game and reach that next level. As such, this eBook assumes readers already have a basic understanding of vSphere and will cover the best practices for four key aspects of any vSphere environment.
The best practices covered here will focus largely on management and configuration solutions so should remain relevant for quite some time. However, with that said, things are constantly changing in IT, so I would always recommend obtaining the most up-to-date information from VMware KBs and official documentation especially regarding specific versions of tools and software updates. This eBook is divided into several sections, and although I would advise reading the whole eBook as most elements relate to others, you might want to just focus on a certain area you’re having trouble with. If so, jump to the section you want read about.
Before we begin, I want to note that in a VMware environment, it’s always best to try to keep things simple. Far too often I have seen environments be thrown off the tracks by trying to do too much at once. I try to live by the mentality of “keeping your environment boring” – in other words, keeping your host configurations the same, storage configurations the same and network configurations the same. I don’t mean duplicate IP addresses, but the hosts need identical port groups, access to the same storage networks, etc. Consistency is the name of the game and is key to solving unexpected problems down the line. Furthermore, it enables smooth scalability - when you move from a single host configuration to a cluster configuration, having the same configurations will make live migrations and high availability far easier to configure without having to significantly re-work the entire infrastructure. Now the scene has been set, let’s get started!
Each version of Windows and Windows Server showcases new technologies. The advent of PowerShell marked a substantial step forward in managing those features. However, the built-in graphical Windows management tools have largely stagnated - the same basic Microsoft Management Console (MMC) interfaces had remained since Windows Server 2000. Microsoft tried out multiple overhauls over the years to the built-in Server Manager console but gained little traction. Until Windows Admin Center.
WHAT IS WINDOWS ADMIN CENTER?Windows Admin Center (WAC) represents a modern turn in Windows and Windows Server system management. From its home page, you establish a list of the networked Windows and Windows Server computers to manage. From there, you can connect to an individual system to control components such as hardware drivers. You can also use it to manage Windows roles, such as Hyper-V.
On the front-end, Windows Admin Center is presented through a sleek HTML 5 web interface. On the back-end, it leverages PowerShell extensively to control the systems within your network. The entire package runs on a single system, so you don’t need a complicated infrastructure to support it. In fact, you can run it locally on your Windows 10 workstation if you want. If you require more resiliency, you can run Windows Admin Center as a role on a Microsoft Failover Cluster.
WHY WOULD I USE WINDOWS ADMIN CENTER?In the modern era of Windows management, we have shifted to a greater reliance on industrial-strength tools like PowerShell and Desired State Configuration. However, we still have servers that require individualized attention and infrequently utilized resources. WAC gives you a one-stop hub for dropping in on any system at any time and work with almost any of its facets.

If you have a business continuity plan or a disaster recovery plan in place, that’s a good place to start. This scenario may not fit the definition of disaster that you originally intended, but it can serve to help you test your plan in a more controlled fashion that can benefit both your current situation by giving you a head start, and your overall plan by revealing gaps that would be more problematic in a more urgent or catastrophic environment with less time to prepare and implement.
Does your plan include access to remote desktops in a data center or the cloud? If so, and you already have a service in place ready to transition or expand, you’re well on your way.
Read the guide to learn what it takes for IT teams to set up staff to work effectively from home with virtual desktop deployments. Learn how to get started, if you’re new to VDI or if you already have an existing remote desktop scenario but are looking for alternatives.
Companies have NAS systems all over the place—hardware-centric devices that make data difficult to migrate and leverage to support the business. It’s natural that companies would desire to consolidate those systems, and vFilO is a technology that could prove to be quite useful as an assimilation tool. Best of all, there’s no need to replace everything. A business can modernize its IT environment and finally achieve a unified view, plus gain more control and efficiency via the new “data layer” sitting on top of the hardware. When those old silos finally disappear, employees will discover they can find whatever information they need by examining and searching what appears to be one big catalog for a large pool of resources.
And for IT, the capacity-balancing capability should have especially strong appeal. With it, file and object data can shuffle around and be balanced for efficiency without IT or anyone needing to deal with silos. Today, too many organizations still perform capacity balancing work manually—putting some files on a different NAS system because the first one started running out of room. It’s time for those days to end. DataCore, with its 20-year history offering SANsymphony, is a vendor in a great position to deliver this new type of solution, one that essentially virtualizes NAS and object systems and even includes keyword search capabilities to help companies use their data to become stronger, more competitive, and more profitable.
