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.

Zerto Offsite Backup in the Cloud
What is Offsite Backup?
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?
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.
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
In this scenario they were able to :
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.
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:
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.
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.
Tintri Analytics is designed from the ground up to support
resource planning. And like everything that Tintri does, Tintri Analytics is
VM-aware, which provides the critical link between storage metrics, VMs and
applications. Having the ability to ask “what-if” questions and see answers in
real time greatly simplifies resource planning.
This paper explains how you can use Tintri Analytics to
answer important resource planning questions:
