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.
The Guide to Selecting Flash for Virtual Environments
High-performance flash-based storage has dramatically improved the storage infrastructure’s ability to respond to the demands of servers and the applications that count on it. Nowhere does this improvement have more potential than in the virtualized-server environment. The performance benefits of flash are so great that it can be deployed indiscriminately and still performance gains can be seen. But doing so may not allow the environment to take full advantage of flash performance. It may also b
Flash storage allows for a higher number of VMs per host. Increasing VM density reduces the number of physical servers required and thereby reduces one of the largest ongoing costs, buying more physical servers, which often are configured with multiple processors and extra DRAM. At the same time, the high performance and low latency of flash allows more mission critical applications to be virtualized. This report explains how storage and hypervisor vendors are getting smarter about leveraging this faster form of storage by including storage quality of service (QoS) intelligence in their systems or environments.
3 things you can ONLY do when your all-flash storage is VM-aware
There’s a disconnect in your data center. You’ve virtualized your applications and your teams are thinking and working in virtual machines.

While many storage products wear the VM-aware label, it doesn’t take much to assess its authenticity. If the product’s architecture is still built on a foundation of LUNs and volumes, it can never be fully VM-aware. 

Truly VM-aware storage is built specifically for virtualized applications. It provides you visibility across your infrastructure, control over performance and complete analytics at the VM level. If your data center is experiencing pain—poor performance, complex management and cost over-runs—you can’t solve it with all-flash or hyperconverged alone. Only VAS can help you see storage differently.

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.

A Deep Dive into Tintri VM Scale-out
This paper illustrates how Tintri’s per-VM management tools work together with predictive analytics and VM Scale-out technology to make it possible to scale out storage while utilizing the management simplicity that is designed into each Tintri VMstore.

LUNs, volumes, RAID, striping and more have nothing to do with the virtual machines and applications that run your business, and only result in storage performance issues and management complexity. Tintri lets you manage what matters: individual virtual machines. With the announcement of VM Scale-out and analytics, Tintri provides virtualization scale-out technology that makes it possible to focus on managing individual VMs instead of storage.

This paper illustrates how Tintri’s per-VM management tools work together with predictive analytics and VM Scale-out technology to make it possible to scale out storage while utilizing the management simplicity that is designed into each Tintri VMstore.

ESG Lab Review: Protecting Virtual Environments with Spectrum Protect Plus from IBM
This ESG Lab Review documents hands-on validation of the IBM Spectrum Protect Plus solution with a focus on how IBM makes deployment and management easy, while delivering multi-workflow recovery agility.
Even today, the reliable protection and recovery of virtual environments continues to be a daunting task for many IT organizations. That said, backup and recovery software does not always make VM protection and recovery easy. As an example, and perhaps most alarmingly, one in nine VM recoveries fails because the data was never backed up. When looking into why VM recoveries fail, one finds a startling range of causes. With so many challenges—the less-than-perfect track records of IT organizations when it comes to VM protection, coupled with failures to meet modern-day SLAs—it is not surprising that some respondents report they continue to lack complete confidence in their VM protection and recovery solution.

It’s apparent through the introduction of the Spectrum Protect Plus solution that these challenges have not been ignored by IBM. Now IBM customers can quickly and easily deploy a solution specifically designed to meet the challenges of virtual machine data protection and administration.
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.
