Virtually every area of human endeavour that involves the use of shared resources relies on a reservation system to manage the booking of these assets. Hotels, airlines, rental companies and even the smallest of restaurants rely on reservation systems to optimize the use of their assets and balance customer satisfaction with profitability. Or, as economists would say, strike a balance between supply and demand.
So how can a modern IT environment expect to operate effectively without having a functioning capacity reservation system? The simple answer is that it can't. With the rise of cloud computing, where resources are shared on a larger scale and capacity is commoditized, modeling future bookings and proper forecasting of demand is critical to the survival of IT. Not having proper systems in place leaves forecasting to trending and guesswork - a dangerous proposition that usually results in over-provisioning and excessive capacity.
Download this paper to learn how to manage the demand pipeline for new workload placements in order to improve the accuracy of capacity forecasting and increase agility in response to new workload placement requests.
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.

Active Directory (AD) offers IT system administrators a central way to
manage user accounts and devices in an IT infrastructure network. Active
Directory authenticates and authorizes users when they log onto devices
and into applications, and allows them to use the settings and files
across all devices in the network. Active Directory services are
involved in multiple aspects of networking environments and enable
interplay with other directories. Considering the important role AD
plays in user data-management and security, it’s important to deploy it
properly and consistently follow best practices.
Active Directory Basics is a tutorial
that will help you address many AD management challenges. You’ll learn
what really goes on under the Active Directory hood, including its
integration with network services and the features that enable its many
great benefits. This white paper also explains how administrators can
make changes in AD to provide consistency across an environment.
In addition, the Active Directory Basics tutorial explains how to:
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.
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?
Why Rely on Backup Shipping as Your VMware DR Solution?
people think, if you want to protect data in your virtual VMware
environment, your easiest solution is to backup VMware using snapshots
or agents. However, solutions like this, such as Veeam, can slow down
your production environment, and they are difficult to scale.
many of us understand that backup is not disaster recovery. The right
approach to a BC/DR solution is hypervisor-based replication.
With hypervisor-based replication you receive:
Optimizing the way applications are delivered and managed
has been an ongoing challenge in enterprise IT, and the variety of approaches
over the years have been received with varying degrees of success. While every
method has pros and cons, some of the most stubborn issues include
time-to-deliver, application conflicts, plug-ins and licensing. The
too-frequent result is high IT overhead, too many gold images and excess
spending on application licenses.
Too many companies are settling on less than optimal
solutions because that is all they are presented with and they are unaware of
the true state of the art for application management. It is possible to
dramatically reduce the number of Windows gold images, in some cases to a
single image. It is possible to deliver exactly what each and every end user
needs to do their job, and nothing else. It is possible for a user to log into
a random system and instantly be presented with their personal desktop, all the
right applications, plugins and add-ons, the right printers, and the right
fonts. It is possible and it is simple.
Citrix AppDisk, when integrated with FSLogix Apps, provides
a unique set of features that can improve end-user productivity, reduce IT
overhead and lower the cost of desktop management. With FSLogix patent pending
Image Masking technology, AppDisk gains very granular and powerful user-based
policy control over every aspect of a user’s desktop and applications, and
enhances the ability to distribute applications on network attached disk images.
FSLogix Apps also enable AppDisks to scale to a much greater degree than any
other similar technologies available today.

comprehensive checklist of monitoring-related criteria that should be
considered as part of due diligence by enterprises and service providers to
effectively manage performance of their complex Citrix infrastructures. Jo Harder, Application and Desktop Virtualization
Analyst, details a checklist for importance level and vendor consideration
broken out into the following categories:
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.
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.
