How to avoid VM sprawl and improve resource utilization in VMware and Veeam backup infrastructures
You're facing VM sprawl if you're experiencing an uncontrollable increase of unused and unneeded objects in your virtual VMware environment. VM sprawl occurs often in virtual infrastructures because they expand much faster than physical, which can make management a challenge. The growing number of virtualized workloads and applications generate “virtual junk” causing VM sprawl issue. Eventually it can put you at risk of running out of resources.

You're facing VM sprawl if you're experiencing an uncontrollable increase of unused and unneeded objects in your virtual VMware environment. VM sprawl occurs often in virtual infrastructures because they expand much faster than physical, which can make management a challenge. The growing number of virtualized workloads and applications generate “virtual junk” causing VM sprawl issue. Eventually it can put you at risk of running out of resources.

Getting virtual sprawl under control will help you reallocate and better provision your existing storage, CPU and memory resources between critical production workloads and high-performance, virtualized applications. With proper resource management, you can save money on extra hardware.

This white paper examines how you can avoid potential VM sprawl risks and automate proactive monitoring by using Veeam ONE, a part of Veeam Availability Suite. Veeam ONE will arm you with a list of VM sprawl indicators and explain how you can pick up and configure a handy report kit to detect and eliminate VM sprawl threats in your VMware environment.

The ability to leverage the data at the disaster recovery target site or in the cloud for VM backup eliminates the impact on production workloads.

Zerto Offsite Backup in the Cloud

What is Offsite Backup?

Offsite Backup is a new paradigm in data protection that combines hypervisor-based replication with longer retention. This greatly simplifies data protection for IT organizations. The ability to leverage the data at the disaster recovery target site or in the cloud for VM backup eliminates the impact on production workloads.

Why Cloud Backup?

  • Offsite Backup combines replication and long retention in a new way
  • The repository can be located in public cloud storage, a private cloud, or as part of a hybrid cloud solution.
  • Copies are saved on a daily, weekly and monthly schedule.
  • The data volumes and configuration information are included to allow VM backups to be restored on any compatible platform, cloud or otherwise.
User Profile and Environment Management with ProfileUnity
This whitepaper has been authored by experts at Liquidware Labs in order to provide guidance to adopters of desktop virtualization technologies. In this paper, we outline how ProfileUnity was designed to address many of the shortcomings of Roaming Profiles, and basic profile management tools that are just a step away from roaming profiles, in managing user profiles and user-authored data over multiple desktop platforms, including physical upgrades and refreshes, Windows migrations and moves to
User Profile Management on Microsoft Windows desktops continues to provide challenges.  Most Administrators find that Roaming Profiles and even Microsoft UEV generally fall short due to several factors. Profile Corruption, Lack of Customization, and lack of Enterprise Features are just some of the top shortcomings of Microsoft Windows profile management with these options.

Basic tools such as roaming profiles do not support a mixed operating environment, therefore it does not allow users to move among desktops with mixed profile versions, e.g. Windows 7, Windows 10, Server2008, 2012 r2, etc.

The lack of support of mixed OS versions makes Microsoft profile management methods a serious hindrance when upgrading/migrating operating systems. Microsoft profile management tools also only support very limited granular management, so admins do not have the ability to exclude bloated areas of a user profile or to include files and registry keys outside of the profile. Profile bloat is one of the number one reasons for long logon times on Windows desktops.

Most organizations who will upgrade from a previous Windows® OS, such as Windows 7, to Windows 10, will want the flexibility to move at their own pace and upgrade machines on a departmental or ‘as needed’ basis.  As a result, management of Microsoft profiles and migration become a huge challenge for these environments because neither operation is seamlessly supported or functional between the two operating systems.  

A user’s profile consists of nearly everything needed to provide a personalized user experience within Windows.  If one could separate out the user profile from Windows and enable dynamic profiles that can adapt to any Windows OS version, several advantages can be realized:
  • User state can be stored separately and delivered just-in-time to enable workers to roam from workspace to workspace
  • Users’ profiles can co-exist in mixed OS environments or automatically migrate from one OS to the next, making OS upgrades easy and essentially irrelevant during a point-in-time upgrade
  • Integral policies and self-managed settings, such as local and network printer management, as well as security policies, can be readily restored in the event of a PC failure or loss (disaster recovery)
Given the growing complexity and diversity of Windows desktops technologies, today’s desktop administrators are looking for better ways to manage user profiles across the ever-increasing spectrum of desktop platforms available. In this whitepaper, we will cover the issues inherent with Roaming Profiles and how ProfileUnity addresses these issues.
Vembu Changes the Dynamics of Data Protection for  Business Applications in a vSphere Environment
This paper examines how to use Vembu BDR to implement distributed backup and disaster recovery (DR) operations in a centrally managed data protection environment with an ingenious twist. Rather than store image backups of VMs and block-level backups of physical and VM guest host systems as a collection of backup files, Vembu BDR utilizes a document-oriented database as a backup repository, dubbed VembuHIVE, which Vembu virtualizes as a file system.
Normal 0 false false false EN-US X-NONE X-NONE In this analysis, openBench Labs assesses the performance and functionality of the Vembu Backup & Disaster Recovery (BDR) host-level (a.k.a. agentless) data protection solution in a VMware vSphere 5.5 HA Cluster. For this test they utilized a vSphere VM configured with three logical disks located on separate datastores to support an Exchange server with two mailbox databases. Each of the mailbox databases was configured to support 1,000 user accounts.

This paper provides technically savvy IT decision makers with the detailed performance and resource configuration information needed to analyze the trade-offs involved in setting up an optimal data protection and business continuity plan to support a service level agreement (SLA) with line of business (LoB) executives.

To test backup performance, they created 2,000 AD users and utilized LoadGen to generate email traffic. Each user received 120 messages and sent 20 messages over an 8-hour workday. Using this load level, we established performance baselines for a data protection using direct SAN-based agentless VM backups.

In this scenario they were able to :

  • Finish crash-consistent incremental agent-less backups in 18 minutes, while processing our base transaction load of 12 Outlook TPS.
  • Restore a fully functional VM in less than 5 minutes as a Hyper-V VM capable of sustaining an indefinite load of 4 Outlook TPS
  • Recover all user mailboxes as .pst files from a host-level agentless VM backup with no need to schedule a Windows Client backup initiated within the VM’s guest Windows OS.
In a DR scenario, Vembu leverages the ability to restore a VM in any format, to provide an Instant-boot function, When Vembu Backup Server is installed on a server that is concurrently running Hyper-V, Vembu exports the datastores associated with a VM backup as Hyper-V disks and configures a VM to boot from the datastores.
True 15-Minute RTO for Mission-Critical VM Systems with Vembu VMBackup Replication
Vembu Backup & Disaster Recovery (BDR) provides IT with a Disaster Recovery Management (DRM) system capable of meeting even more aggressive RTO and RPO goals than the previous release. For highly active database-driven systems, Vembu VMBackup leverages VMtools and VMware Changed Block Tracking (CBT) to perform incremental backups in 15-minute intervals with minimal impact on query processing. As a result, IT can limit data loss to 15 minutes of processing on active mission critical VMs.

The only way to recover a VM with full functionality and full performance without performing an explicit restore operation is through VM replication. Maintaining a replica VM, however, requires frequent and potentially expensive update processes that involve both explicit backup and implicit restore operations. To enable the extensive use of replication by IT, VMBackup adds critical optimizations to both restore and replication operations that dramatically minimize overhead on ESXi hosts and production VMs to just VM snapshot processing. Specifically, a BDR Backup server running on a VM is able to leverage hot-add SCSI transfer mode to write logical disk and logical disk snapshot files directly to a vSphere datastore, without involving the ESXi host for anything more than creating a VM snapshot.

A key a value proposition for Vembu VMBackup is its ability to directly read and write all backup and restore data directly to and from a datastore snapshot. As a result, Vembu VMBackup offloads all I/O overhead from production VMs and ESXi hosts, which is critical for maintaining an aggressive DRM strategy in a highly active virtual environment. What’s more, the performance of Vembu VMBackup in openBench lab's test environment made it possible to enhance support for a mission-critical OLTP application running on a VM using a combination of incremental backups for backup and replication. As a result, they were able to comply with a 30-minute RPO, restore the VM to a production environment in 5 minutes, and return to full-production level processing of business transactions—850 cTPS—in under 15 minutes.

VMBackup adds a new replica management module that enables an IT administrator to fully manage an initial failover and later finalize failover or failback with consolidation. In addition, BDR backup server simplifies all management functions by eliminating the need to run a separate client module on a BDR backup server, which becomes its own client within the BDR reporting hierarchy.

Vembu OffsiteDR Server: Optimize RPO & RTO While Enhancing DR Resilience
Vembu BDR’s data protection solution enhances DRM operations by eliminating all potential single points of failure for restore functions. Using Vembu BDR Suite, IT is able to replicate backup data from multiple BDR Backup servers to a system running OffsiteDR Server within their own data center. As a result, IT garners an alternate system from which to recover protected VMs and physical servers using the same procedures that IT administrators employ on a BDR Backup server.

The ability to configure and deploy high-performance VMs within a vSphere virtual environment continues to put CIO’s under increasing pressure to deal with the rampant bête noire of IT: business continuity. What started with Line of Business (LoB) driven Service Level Agreements (SLAs) requiring IT to meet rigorous Recovery Time and Recovery Point Objectives (RTO and RPO) has grown into an auditable ISO standard (ISO22301) and an emerging software niche for Disaster Recovery Management (DRM) systems.

For this analysis, openBench Labs assessed the performance and functionality of the Vembu OffsiteDR Server, a DRM device that increases the resilience of recovery processes. Their initial intent was to examine the ability to restore data in the event of a catastrophic failure in vSphere environment, including:

  • A VM running BDR Backup server,
  • an ESXi host, and
  • a SAN device.

The full capabilities of Vembu OffsiteDR Server, however, quickly revealed that the device had a much broader operational impact. With the installation of OffsiteDR Server on an external physical server, they were free to configure end-to-end backup and restore operations in a way that optimized RTO and RPO for all business-critical application scenarios running in vSphere test environment.

In openBench lab's test environment, the combination of Vembu OffsiteDR Server deployed on a physical server with a Vembu BDR Backup server deployed on a VM provided a value proposition that extended far beyond the enhancement of DRM recovery resilience. With OffsiteDR Server installed on a physical server, they were able to optimally leverage VM and physical server platforms to easily implement all of the data protection functionality provided by Vembu BDR Suite, leverage all of the performance optimizations available to VMs in a vSphere environment, and do so in the most cost-effective system configuration.

This checklist provides an overview to help plan a datacenter migration project and ensure accountability through each step including:
  • Communication: Maintain clear, and regular communication with everyone.
  • Scoping: Understand what makes up the application. Get rid of the unknowns to ensure nothing breaks.
  • Ownership and permissions: Who owns the server and application and who will test and validate pre and post migration?
  • Priority: Are there other projects in your way?
  • Organization: Checklists and spreadsheets: How are you tracking all of this?
  • Execution: How is the migration happening? How will the servers and data be moved?
  • Contingency: If something goes wrong, how do I back out and reschedule if necessary?
  • Tracking: Prepare for change. Track what changes need to occur on machines, applications, and infrastructure.
  • Data Hygiene: Cleanup the source environment
The Next Generation Clusterless Federation Design in the Cloudistics Cloud Platform
Is there another way to manage your VMs? Yes, the introduction of the Cloudistics Cloud Platform has an innovative approach – non-clustered (or clusterless) federated design.The clusterless federation of the Cloudistics Cloud platform uses categories and tags to characterize computer nodes, migration zones, and storage groups (or blocks). With these benefits: ⦁ Node Limits Are A Thing of the Past. ⦁ Locking limitations are removed. ⦁ Flexibility is Enhanced. ⦁ Ladders of Latency are Removed. ⦁

This paper is written in the context of modern virtualized infrastructures, such as VMware or Nutanix. In such systems, a hypervisor runs on each compute node creating multiple virtual machines (VMs) per compute node. A guest OS runs inside each VM.

Data associated with each VM is stored in one or more virtual disks (vDisks). A virtual disk appears like a local disk, but can be mapped to physical storage in many ways as we will discuss.

Virtualized infrastructures use clustering to provide for non-disruptive VM migration between compute nodes, for load balancing across the nodes, for sharing storage, and for high availability and failover. Clustering is well known and has been used to build
computer systems for a long time. However, in the context of virtualized infrastructures, clustering has a number of significant limitations. Specifically, as we explain below, clusters limit scalability, decrease resource efficiency, hurt performance, reduce flexibility and impair manageability.

In this paper, we will present an innovative alternative architecture that does not have these limitations of clustering. We call our new approach clusterless federation and it is the approach used in the Cloudistics platform.

The rest of this paper is organized as follows. In Section 2, we describe the limitations of clustering and in Section 3, we drive the point home by using the specific example of VMware; other virtualized systems are similar. In Section 4, we present the clusterless federated approach and show how it avoids the limitations of clustering. We summarize in Section 5.

Essential Guide for Application-Centric Workload Migrations to Hybrid Cloud
Essential guide on migrating from the Private to the Hybrid Cloud environment.

IT leaders turn an eye toward the cloud when they’re looking to solve elasticity and scalability issues. One of the key differentiators of the cloud as compared to traditional infrastructure is that it’s inherently flexible.

Migrating workloads, especially complex, multi-tiered applications, can be a harrowing process. Undertaking the migration without a solid understanding of the interdependencies of applications and the exact resource requirements means almost certain failure. In today’s world, it’s understandable that failures can, do, and will happen; what’s not acceptable today is downtime. Cutovers of migrations need to be instant, or an hour at most.

Read this essential guide on Workload Migrations to learn about:

  • Availability Service Level Agreements
  • On-Premises to Public Cloud Migrations
  • Data Center to Data Center Migrations
  • Workload Migration Challenges
  • Migrate Successfully with Application-Centric Workload Visibility
Switch to Parallels Remote Application Server and Save 60% Compared to Citrix XenApp
This article will explain how Parallels Remote Application Server can easily act as a business’s desktop and application delivery solution, offering the same qualities as other leading solutions such as Citrix XenApp, but at an entirely different and affordable price. As a result, companies who opt to use Parallels Remote Application Server could save up to 60%, while gaining added flexibility and maneuverability for their devices.
A few years ago, Citrix had two separate products for its virtualization solutions: XenApp and XenDesktop. In 2016, Citrix merged them into a single product; XenDesktop 7. The change was not well received by Citrix customers, and Citrix has split them again into XenApp and XenDesktop from version 7.5 onward. The major difference between XenApp and XenDesktop is the type of virtual desktop delivered to the user. XenDesktop includes all XenApp features and also has a VDI solution, so from this point on we will use the XenDesktop term in this document to refer to Citrix virtualization solution: published applications and virtual desktop infrastructure. Although XenDesktop is the most popular solution in the industry, it has several shortcomings coupled with a very expensive price tag. Due to migration from Independent Management Architecture (IMA) to Flexcast Management Architecture (FMA), there is no option in place to upgrade to XenDesktop 7.x from previous versions of XenApp (5 or 6.X). Therefore, now is the right time to jump ship. In this white paper, we examine how migrating to Parallels Remote Application Server can reduce the costs of an application and virtual desktop delivery solution by more than 60%. Parallels RAS is an easy-to-use, scalable application and desktop delivery solution which has the lowest total cost of ownership amongst its competitors. Considered an industry underdog by many, Parallels Remote Application Server has been in the industry since 2005, and many Citrix customers have already switched to Parallels RAS.
