This is not a paper on disk defrag. Although conceptually similar, it describes an entirely new approach to server optimization that performs a similar operation on the compute, memory and IO capacity of entire virtual and cloud environments.
Capacity defragmentation is a concept that is becoming increasingly important in the management of modern data centers. As virtualization increases its penetration into production environments, and as public and private clouds move to the forefront of the IT mindset, the ability to leverage this newly-found agility while at the same driving high efficiency (and low risk) is a real game changer. This white paper outlines how managers of IT environments make the transition from old-school capacity management to new-school efficiency management.
When Windows Server 2012 hit the market in 2012 a new feature called - Hyper-V Replica
hit the shelf. In 2013, when Windows Server 2012 R2 was released, the
Hyper-V Replica feature was improved. This white paper gives you an
in-depth look at Hyper-V Replica: what it is, how it works, what
capabilities it offers and specific-use cases.
By the end of this white paper, you’ll know:
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
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.

ESG Lab Spotlight evaluates the power of SIOS iQ Machine Learning and Flashsoft software to enable companies to improve application performance through easy, cost-efficient host based caching with solid-state storage devices (SSDs).by reducing storage bottlenecks, speeding application performance, and minimizing latency. However, the challenge for many organizations, especially since many SSDs are still more expensive than HDDs, is to know when and where to apply SSDs to both maximize performance and minimize costs. This lab report evaluates the SIOS iQ IT Analytics and SanDisk FlashSoft, ioMemory, and SSDs. SIOS iQ, a machine learning analytics platform for optimizing VMware environments, identifies which virtual machines will benefit most from host-based caching and recommends the configuration that will provide the best results. FlashSoft host-based caching software leverages SanDisk Fusion ioMemory PCIe application accelerators, SanDisk Lightning, Optimus, and CloudSpeed SSDs, or any other solid-state storage device, to reduce latency and improve throughput in read-intensive virtual and physical server workloads.
ESG Lab used a simulated enterprise IT infrastructure to validate how organizations can use the SIOS iQ analytics platform to identify applications that could be accelerated with host-based caching software, recommend an optimal cache configuration, and predict the resulting storage performance if caching were configured as recommended.
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.
This white paper was created to help organizations make
the right choice for them, whether it be deploying infrastructure in the cloud
or on a dedicated platform. It discusses the many approaches to cloud and
dedicated platforms, highlighting a few use cases along the way.
