How VembuHIVE, a backup repository as a file system is changing the dynamics of Data Protection
MS Applications are a critical segment of the core systems managed and run in IT of most organizations. Backing them up is not enough. The effect of the backup process on your system and storage determines its efficiency. From this whitepaper, learn how VembuHIVE transforms the way backups are performed to achieve disaster-readiness.
It is imperative that Microsoft Applications like SQL, Exchange, Active Directory and many others have been instrumental in running some of the mission-critical processes of an IT setup. While there are many solutions that address its Data Protection concerns, efficient recovery from a storage medium has always been a pivotal issue. Read this white paper that includes performance and resource utilization reports on how Vembu BDR Suite with its in-house proprietary file system VembuHIVE, reduces the backup footprints on the storage repositories enabling quick recovery with minimal RTOs.
UNC Health Care Leverages IGEL in Virtual Desktop Infrastructure Deployment
UNC Health Care selected IGEL Universal Desktop Converter (UDC) and IGEL Universal Management Suite (UMS) for simplicity, cost-savings and security. This document outlines key findings on how IGEL helps organizations manage entire fleets of thin clients from a single console.

UNC Health Care selects IGEL Universal Desktop Converter (UDC) and IGEL Universal Management Suite (UMS) for simplicity, cost-savings and security.

“The need to provide users with access to their desktops from any device anywhere, anytime is driving a growing number of IT organizations to migrate toward VDI environments,” said Simon Clephan, Vice President of Business Development and Strategic Alliances, IGEL. “One of the key advantages that IGEL brings to the table is the simplicity that comes from being able to manage an entire fleet of thin clients from a single console. Additionally, the IGEL Universal Desktop Converter provides IT organizations with the flexibility they need to convert any compatible thin client, desktop or laptop computer into an IGEL thin client solution, without having to make an upfront investment in new hardware to support their virtualized infrastructures.” 

UNC Health Care selected the IGEL UDC and UMS software for its Citrix VDI deployment following a “bake-off” between thin client solutions. “IGEL won hands down due the simplicity and superiority of its management capabilities,” said James Cole, Technical Architect, UNC Health Care. “And, because the IGEL UDC software is designed to quickly and efficiently convert existing endpoint hardware into IGEL Linux OS-powered thin clients, we knew that by selecting the IGEL solution we would also realize a significant reduction in our capital expenditures.”

Since initiating the deployment of the IGEL UDC and UMS software, UNC Health Care has also experienced significant time savings. “Prior to deploying the IGEL UDC and UMS software, it took our team 25-30 minutes to create a virtual image on each system, not counting the personalization of the system for each use case, now that process takes less than 10 minutes, and even less time when converting the system to VDI roaming,” added Cole.

Additionally, the ease of integration between the IGEL UDC and IGEL UMS with Citrix XenDesktop and other solutions offered by Citrix Ecosystem partners, including Imprivata, has enabled secure access to the health care network’s Epic Systems’ Electronic Medical Records (EMR) system.

Ovum: Igel's Security Enhancements for Thin Clients
Thin client vendor Igel is enhancing the security capabilities of its products, both under its own steam and in collaboration with technology partners. Ovum sees these developments as important for the next wave of thin client computing, which will be software-based – particularly if the desktop-as-a-service (DaaS) market is to take off.

With hardware-based thin client shipments in the region of 4–5 million units annually, this market is still a drop in the ocean compared to the 270 million PCs shipping each year, though the latter figure has been declining since 2011. And within the thin client market, Igel is in fourth place behind Dell and HP (each at around 1.2 million units annually) and China’s Centerm, which only sells into its home market.

However, the future for thin clients looks bright, in that the software-based segment of the market  (which some analyst houses refuse to acknowledge) is expanding, particularly for Igel. Virtual desktop infrastructure (VDI) technology has stimulated this growth, but the greatest promise is probably in the embryonic DaaS market, whereby enterprises will have standard images for their workforce hosted by service providers.

Optimizing Performance for Office 365 and Large Profiles with ProfileUnity ProfileDisk
Managing Windows user profiles can be a complex and challenging process. Better profile management is usually sought by organizations looking to reduce Windows login times, accommodate applications that do not adhere to best practice application data storage, and to give users the flexibility to login to any Windows Operating System (OS) and have their profile follow them.

Managing Windows user profiles can be a complex and challenging process. Better profile management is usually sought by organizations looking to reduce Windows login times, accommodate applications that do not adhere to best practice application data storage, and to give users the flexibility to login to any Windows Operating System (OS) and have their profile follow them. Note that additional profile challenges and solutions are covered in a related ProfileUnity whitepaper entitled “User Profile and Environment Management with ProfileUnity.” To efficiently manage the complex challenges of today’s diverse Windows profile environments, Liquidware ProfileUnity exclusively features two user profile technologies that can be used together or separately depending on the use case.

These include:

1. ProfileDisk, a virtual disk based profile that delivers the entire profile as a layer from an attached user VHD or VMDK, and

2. Profile Portability, a file and registry based profile solution that restores files at login, post login, or based on environment triggers.

Application & Desktop Delivery for Dummies
In this book, you learn how solutions, such as Parallels Remote Application Server (RAS), replace traditional application deployment with on-demand application delivery, and why it's right for your organization.
Applications are essential to the businesses and organizations of all sizes and in all industries. End-users need to have continuous and reliable access to their applications whether working in the office or remotely, at any time of the day or night, and from any device. With the advent of cloud computing, office desktops with installed applications (that had to be constantly updated) have become a thing of the past — application streaming, virtual desktop infrastructure (VDI), and hosted applications are the future (and the present, for that matter). Application virtualization is an easy way to manage, distribute, and maintain business applications. Virtualized applications run on a server, while end-users view and interact with their applications over a network via a remote display protocol. Remote applications can be completely integrated with the user’s desktop so that they appear and behave like local applications. Today, you can dynamically publish applications to remote users in several ways. The server-based operating system (OS) instances that run remote applications can be shared with other users (a terminal services desktop), or the application can be running on its own OS instance on the server (a VDI desktop).

vSphere Troubleshooting Guide
Troubleshooting complex virtualization technology is something all VMware users will have to face at some point. It requires an understanding of how various components fit together and finding a place to start is not easy. Thankfully, VMware vExpert Ryan Birk is here to help with this eBook preparing you for any problems you may encounter along the way.

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!
