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.

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.
ESG Lab Spotlight: SIOS iQ & FlashSoft: Analytics-driven Server Acceleration
Download this ESG Lab Spotlight and learn how easy accelerating performance in your VMware environment through host-based caching can be. ESG Lab looked at a new approach that uses SIOS iQ machine learning analytics platform to identify candidate VMs that can be accelerated with FlashSoft host-based caching software using SanDisk Fusion ioMemory PCIe application accelerators and SanDisk SAS and SATA SSDs. They validated the benefits of this approach in this detailed Lab Spotlight

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.

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: The Biggest Little Data Protection Company You Probably Haven't Heard Of (Yet)
Vembu wants to do more to let people know that it exists—it wants its own name to be in the marketplace and attached to its products—especially after hearing from many customers who desire to know whom the products they rely on truly belong to. So, in the past year, Vembu established relationships with more VARs and reached out directly to select enterprise and midmarket segments. It added 400 channel partners, 180 VARs, and 300 customers in 2014 alone.

If it appears that this analyst is impressed with Vembu, he is. Vembu’s feature set surpasses what one might presume to come from a backup company that most folks (in North America at least) haven’t heard of.And although it would be easy to assume that some of Vembu’s capabilities are mere boasts, the hesitations wash away with the recognition that this is a vendor with ten years in the business, and that well over half its workforce are R&D engineers. Said another way, Vembu appears to have been quietly solving its customers’ backup challenges for more than a decade through technology, instead of marketing.

In fact, not only did Vembu not have a marketing team until 2015, but it also didn’t have a sales team to speak of. This is an incredibly engineering-focused company—one whose revenues and customers have accumulated through word of mouth. But now, Vembu is building out a solid U.S.-based sales and marketing engine focused on penetrating awareness among IT decision makers, especially decision makers in the SMB segment.

The product Vembu will push in 2015, BDR 2.0, could be a “game changer” for Vembu’s growth. BDR appears to have the potential to quite effectively address the varied requirements of small and midmarket businesses who run mixed physical and virtual IT environments and who also want to leverage the cloud.

If Vembu continues to invest as much into its North American marketing and channel outreach programs as it historically has invested into engineering its technology, then 2015 could be the year that a lot of SMBs discover the “secret” to solving a lot of their backup problems.

European and APJ businesses may know Vembu, but many U.S. IT organizations will be surprised by the solution set of this ten-year-old company that is launching its first concerted marketing push into North America.

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.

Growing at 35% per year, Vembu branches out from its backup/recovery roots
Cloud­based backup/recovery is a cutthroat business with shrinking margins, commoditization and a surfeit of contenders trying to get a piece of the pie. The company's decision to push its resellers away from rebranding and into carrying Vembu's name on their services will give it much ­needed name/brand recognition in a crowded arena.

Vembu has grown its revenue 35% annually over the past two years and is on track to meet that mark in 2014. Key product additions this year include a suite of CRM applications and the introduction of on­premises virtual appliances (with physical appliances to come in the near future). The latter move puts Vembu in more direct competition with relatively well ­known players in the hybrid cloud backup battle.

Vembu is celebrating its 10­ year anniversary by exceeding the 60,000 ­customer milestone, sold mainly through its 4,400 channel partners. That compares with 55,000 customers and 4,000 resellers in February 2014. The company has added 400 resellers so far this year, and has begun to emphasize VARs in addition to its traditional target market of MSPs. Notable service­provider partners include Verizon's Terremark subsidiary, mindSHIFT Technologies, HostPapa and Hitachi Data Systems. The profitable Vembu claims to have exceeded 35% revenue growth in each of the past two years, and is on track for similar gains this year.

The company expects to have 200 employees by the end of 2014 (up from 160 in February), and 300 by the end of 2015. Most of its employees are near its headquarters in Chennai, India (with 65% engaged in R&D), but Vembu has been steadily expanding internationally. It opened an office in London this year, and relocated its US headquarters to Addison, Texas, where it expects to grow its workforce from 15 employees this year to 50 next year Vembu's worldwide distribution of partners roughly equates to its worldwide revenue distribution: 70% North America, 20% Europe and 10% AsiaPacific – a distribution that has remained fairly steady over the past year. However, although about 30% of its revenue comes from outside North America today, Vembu hopes to increase that to 50% in 2015. Key target markets for 2015 include the EU­5 countries, Scandinavia, Brazil and China

Does Backup Need a File System of its Own?
VembuHIVETM is an efficient cloud file system designed for large-scale backup and disaster recovery (BDRTM) application with support for advanced use-cases. VembuHIVETM can be thought of as a File System of File Systems with in-built version control, deduplication (elimination of redundant information to enhance storage reduction), encryption, and in-built error correction.

Backup is just not about storage. It’s the intelligence on top of storage. Typically when businesses think of backup, they see it as a simple data copy from one location to another. Traditional file systems would suffice if the need were to just copy the data. But backup is the intelligence applied on top of storage where data can be put to actual use. Imagine the ability to use backup data for staging, testing, development and preproduction deployment. Traditional file systems are not designed to meet such complex requirements.

With the advent of information technology, more and more organizations are relying on IT for running their businesses. They cannot afford to have downtime on their critical applications and need instant access to data in the event of disaster. Hence, a new type of file system is necessary to satisfy this need. 

VembuHIVETM manages the metadata smartly through its patent-pending technology, in a way that is agnostic to the file system of the backup, which is why we call VembuHIVETM, a file system of file systems. This helps the backup application to instantly associate the data in VembuHIVETM to any file system metadata, thereby allowing on-demand file or image restores in many possible file formats. The data and metadata storage, harness cluster file system and computing and storage.

This is a really powerful concept that will address some very interesting use cases not just in the backup and recovery domain but also in other domains, such as big-data analytics.

The key to the design of VembuHIVETM is its novel mechanism to capture and generate appropriate metadata and store it intelligently in a cloud infrastructure. The increment data (the changes with respect to a previous version of the same backup) are treated like versions in a version control system (CVS, GIT). This revolutionary way of data capture and metadata generation provides seamless support to a wide range of complex restore use cases.
