In this paper, we outline the Architectural components and considerations for our Stratusphere FIT and Stratusphere UX products. This paper is intended for technical audiences who are already generally familiar with these solutions and the functionality they provide.
As more organizations prepare for and deploy hosted virtual desktops, it has become clear that there is a need to support two related but critical phases. The first is to inventory and assess the physical desktop environment in order to create a baseline for the performance and quality of the user experience for the virtual desktop counterparts. When planning and preparing, organizations would like to know which desktops, users and applications are a good fit for desktop virtualization and which ones are not. The second phase is to track the virtual desktops in production in order to proactively identify when performance and user experience does not meet expectations, as well as to continue to refine and optimize the desktop image and infrastructure as changes are introduced into the environment.
Because virtual desktops live on shared systems, the layers of technology make it more complex to measure and classify fitness and user experience. But with increased industry knowledge and the emergence of best practices, plus new purpose-built products such as Liquidware Labs’ Stratusphere FIT and Stratusphere UX, it is now possible to more accurately measure and classify both fitness and user experience. This white paper covers these best practices and provides an introduction to the VDI FIT and VDI UX classification capabilities in Stratusphere FIT and Stratusphere UX.
This whitepaper provides an overview of Citrix AppDNA with Liquidware Labs FlexApp.
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.
What does good copy data management look like? According to ESG, it starts with seamless integration into existing IT infrastructure rather than a requirement to create yet another copy of data. This allows organizations to truly modernize their IT infrastructure and application-focused processes.
