5 Fundamentals of Modern Data Protection
Some data protection software vendors will say that they are “agentless” because they can do an agentless backup. However, many of these vendors require agents for file-level restore, proper application backup, or to restore application data. My advice is to make sure that your data protection tool is able to address all backup and recovery scenarios without the need for an agent.
Legacy backup is costly, inefficient, and can force IT administrators to make risky compromises that impact critical business applications, data and resources. Read this NEW white paper to learn how Modern Data Protection capitalizes on the inherent benefits of virtualization to:
  • Increase your ability to meet RPOs and RTOs
  • Eliminate the need for complex and inefficient agents
  • Reduce operating costs and optimize resources
The Expert Guide to VMware Data Protection
Virtualization is a very general term for simulating a physical entity by using software. There are many different forms of virtualization that may be found in a data center including server, network and storage virtualization. When talking about server virtualization there are many unique terms and concepts that you may hear that are part of the technology that makes up server virtualization.
Virtualization is the most disruptive technology of the decade. Virtualization-enabled data protection and disaster recovery is especially disruptive because it allows IT to do things dramatically better at a fraction of the cost of what it would be in a physical data center.

Application Response Time for Virtual Operations
For applications running in virtualized, distributed and shared environments it will no longer work to infer the performance of an application by looking at various resource utilization statistics. Rather it is essential to define application performance by measuring response and throughput of every application in production. This paper makes the case for how application performance management for virtualized and cloud based environments needs to be modernized to suit these new environments.

Massive changes are occurring to how applications are built and how they are deployed and run. The benefits of these changes are dramatically increased responsiveness to the business (business agility), increased operational flexibility, and reduced operating costs.

The environments onto which these applications are deployed are also undergoing a fundamental change. Virtualized environments offer increased operational agility which translates into a more responsive IT Operations organization. Cloud Computing offers applications owners a complete out-sourced alternative to internal data center execution environments. IT organizations are in turn responding to public cloud with IT as a Service (IaaS) initiatives.

For applications running in virtualized, distributed and shared environments, it will no longer work to infer the “performance” of an application by looking at various resource utilization statistics. Rather it will become essential to define application performance as response time – and to directly measure the response time and throughput of every application in production. This paper makes the case for how application performance management for virtualized and cloud based environments needs to be modernized to suit these new environments.

How Software-Defined Storage Enhances Hyper-converged Storage
This paper describes how to conquer the challenges of using SANs in a virtual environment and why organizations are looking into hyper-converged systems that take advantage of Software-Defined Storage as a solution to provide reliable application performance and a highly available infrastructure.
One of thefundamental requirements for virtualizing applications is shared storage.Applications can move around to different servers as long as those servers haveaccess to the storage with the application and its data. Typically, sharedstorage takes place over a storage network known as a SAN. However, SANstypically run into issues in a virtual environment, so organizations arecurrently looking for new options. Hyper-converged infrastructure is a solutionthat seems well-suited to address these issues.

Building a Highly Available Data Infrastructure
Topics: DataCore, storage, SAN, HA
This white paper outlines best practices for improving overall business application availability by building a highly available data infrastructure.
Regardless of whether you use a direct attached storage array, or a network-attached storage (NAS) appliances, or a storage area network (SAN) to host your data, if this data infrastructure is not designed for high availability, then the data it stores is not highly available by extension, application availability is at risk – regardless of server clustering.

Scale Computing’s hyperconverged system matches the needs of the SMB and mid-market
Scale Computing HC3 is cost effective, scalable and designed for installation and management by the IT generalist
Everyone has heard the buzz about hyper-converged systems – appliances with compute, storage and virtualization infrastructures built in – these days. Hyper-converged infrastructure systems are an extension of infrastructure convergence – the combination of compute, storage and networking resources in one compact box – that promise of simplification by consolidating resources onto a commodity x86 server platform.
2015 State of SMB IT Infrastructure Survey Results
Overall, companies of all sizes are moving faster to virtualize their servers but very few are taking advantage of hyperconvergence and all that it offers.
Demandson IT in small and medium businesses (SMBs) continue to rise exponentially.Budget changes, increased application and customization demands, and more arestretching IT administrators to the limit. At the same time, new technologieslike hyperconverged infrastructure bring light to the end of thestrained-resources tunnel through improved efficiency, scaling, and managementbreakthroughs. More and more, IT groups at SMBs are being pushed to “do morewith less,” as the unwelcome saying goes. So, in order to meet thesechallenges, some SMBs leverage new technology.

Why Parallel I/O & Moore's Law Enable Virtualization and SDDC to Achieve their Potential
Today’s demanding applications, especially within virtualized environments, require high performance from storage to keep up with the rate of data acquisition and unpredictable demands of enterprise workloads. In a world that requires near instant response times and increasingly faster access to data, the needs of business-critical tier 1 enterprise applications, such as databases including SQL, Oracle and SAP, have been largely unmet.

Today’s demanding applications, especially within virtualized environments, require high performance from storage to keep up with the rate of data acquisition and unpredictable demands of enterprise workloads. In a world that requires near instant response times and increasingly faster access to data, the needs of business-critical tier 1 enterprise applications, such as databases including SQL, Oracle and SAP, have been largely unmet. 

The major bottleneck holding back the industry is I/O performance. This is because current systems still rely on device -level optimizations tied to specific disk and flash technologies since they don’t have software optimizations that can fully harness the latest advances in more powerful server system technologies such as multicore architectures. Therefore, they have not been able to keep up with the pace of Moore’s Law.

Waiting on IO: The Straw That Broke Virtualization’s Back
In this paper, we will discuss DataCore’s underlying parallel architecture, how it evolved over the years and how it results in a markedly different way to address the craving for IOPS (input/output operations per second) in a software-defined world.
Despite the increasing horsepower of modern multi-core processors and the promise of virtualization, we’re seeing relatively little progress in the amount of concurrent work they accomplish. That’s why we’re having to buy a lot more virtualized servers than we expected.

On closer examination, we find the root cause to be IO-starved virtual machines (VMs), especially for heavy online transactional processing (OLTP) apps, databases and mainstream IO-intensive workloads. Plenty of compute power is at their disposal, but servers have a tough time fielding inputs and outputs. This gives rise to an odd phenomenon of stalled virtualized apps while many processor cores remain idle.

So how exactly do we crank up IOs to keep up with the computational appetite while shaving costs? This can best be achieved by parallel IO technology designed to process IO across many cores simultaneously, thereby putting those idle CPUs to work. Such technology has been developed by DataCore Software, a long-time master of parallelism in the field of storage virtualization.

In this paper, we will discuss DataCore’s underlying parallel architecture, how it evolved over the years and how it results in a markedly different way to address the craving for IOPS (input/output operations per second) in a software-defined world.

FlexApp Application Layering in ProfileUnity enables applications to be virtualized in such an innate way that they look native to the Windows OS and other applications.
FlexApp Application Layering in ProfileUnity enables applications to be virtualized in such an innate way that they look native to the Windows OS and other applications.

Application Layering leads to much higher rates of compatibility than previous technologies which used Application Isolation to virtualize applications. Once applications have been packaged for layering, they are containerized on virtual hard disks (VHDs) or VMDKs.  They can be centrally assigned to users on a machine-level or “context-aware” basis.

This whitepaper provides an overview of FlexApp concepts and ways in which FlexApp can serve as a cornerstone in an application delivery strategy.

Optimizing the way applications are delivered and managed has been an ongoing challenge in enterprise IT, and the variety of approaches over the years have been received with varying degrees of success. While every method has pros and cons, some of the most stubborn issues include time-to-deliver, application conflicts, plug-ins and licensing. The too-frequent result is high IT overhead, too many gold images and excess spending on application licenses.

Too many companies are settling on less than optimal solutions because that is all they are presented with and they are unaware of the true state of the art for application management. It is possible to dramatically reduce the number of Windows gold images, in some cases to a single image. It is possible to deliver exactly what each and every end user needs to do their job, and nothing else. It is possible for a user to log into a random system and instantly be presented with their personal desktop, all the right applications, plugins and add-ons, the right printers, and the right fonts. It is possible and it is simple.

Citrix AppDisk, when integrated with FSLogix Apps, provides a unique set of features that can improve end-user productivity, reduce IT overhead and lower the cost of desktop management. With FSLogix patent pending Image Masking technology, AppDisk gains very granular and powerful user-based policy control over every aspect of a user’s desktop and applications, and enhances the ability to distribute applications on network attached disk images. FSLogix Apps also enable AppDisks to scale to a much greater degree than any other similar technologies available today.

This document details what is possible when FSLogix is combined with Citrix AppDisk and suggests best practices for installing and configuring the products for maximum flexibility and applicability in various environments.
