Virtualization Strategies for the CIO
-
Consider maintenance costs and design for efficiency
Taking an innovative approach to your virtual infrastructure design can minimize time spent on maintenance and improve operational efficiency.
-
Resource contention, other factors limit VM performance
Resource contention plays a huge role in the quest for optimal virtual machine performance, but it's certainly not the only source of bottlenecks.
-
The five most common reasons your VM migration failed
It's not uncommon for a virtual machine restart to fail. Combat VM migration errors by learning to diagnose the error and prevent it from recurring.
-
Easing the legacy server virtualization process
Moving a legacy server to a virtual environment provides the same benefits as virtualizing new servers, though the process is considerably trickier.
-
Data center use cases for Red Hat Storage are limited
Red Hat Enterprise Virtualization data centers can now use Red Hat Storage technology, but whether they will have a practical use for it is unclear.
-
VSphere storage wars: Block-based versus file-based
For performance rivaling Fibre Channel, you can bet on iSCSI or NFS. But one protocol has the edge when it comes to ease of configuration in vSphere.
-
Building a highly available oVirt 3.1 environment
Dodge dreaded downtime by enabling power management in your oVirt 3.1 environment.
-
Building a VMware virtual infrastructure
Building a virtual infrastructure starts with good design and careful planning. These five tips will get you started with a VMware infrastructure.
-
What your physical NIC allocation plan should look like
The way you distribute physical NICs could be affecting more than you think. Boost network efficiency with the right allocation strategy.
-
Cloud migration can wreak havoc on IT budget planning
A lot goes into a cloud migration strategy. IT budget planning -- for today's infrastructure as well as for cloud computing -- has to be part of it.
-
New features make it easier to ditch expensive DR tools
Third parties offer extensive disaster recover protection options, but you may not need to look further than your hypervisor’s built-in capabilities.
-
Getting started and adding VMs with oVirt 3.1
Before you get started using the free oVirt 3.1 hypervisor, you'll need to set up the basic organizational structure and add hosts. Learn how here.
-
Automate to accelerate Hyper-V host deployments
If you're looking to speed up a deployment and add new Hyper-V hosts faster, ditch the graphical tool and use PowerShell to automate the process.
-
Seek and find SCVMM PowerShell cmdlets
If you think you have to memorize 529 cmdlets to use PowerShell to manage SCVMM 2012 SP1, think again.
-
Why you should consider manually controlled HA
High availability has clear benefits, but what about HA without a cluster file system? You may want to opt for a manual HA environment instead.
-
Calculate your virtual data center licensing needs
Licensing virtual servers can get confusing and expensive. Brien Posey shares the ins and outs of server licensing with a Windows Server 2012 example.
-
Now is the time to update your DR plan
Update your business's disaster recovery strategy to take full advantage of virtualization's time- and cost-saving benefits.
-
The 'automate everything' mindset misses the point
IT automation isn't for everyone. Deciding what and how much to automate is an important point to consider before jumping headfirst into automation.
-
Use VMM cmdlets without installing management tools
Learn how to get the cmdlets you need to manage SCVMM from anywhere in the world by using Remoting to import a PowerShell module.
-
Virtualization-aware storage benefits infrastructure
Virtualization admins will have less of an opportunity to blame storage for unidentifiable problems thanks to the advent of hypervisor-aware storage.
-
Hyper-V simplifies storage migration
Live Storage Migration eliminates the downtime associated with moving VM files from one storage location to another and helps improve performance.
-
The practical limits to Hyper-V Live Storage Migration
Live Storage Migration makes it easy to move multiple storage files of running VMs without downtime, but there are practical limits you should know.
-
The Xen hypervisor may be poised for a revival
After falling out of favor among many Linux distributions, the Xen hypervisor may be on the verge of a comeback, courtesy of the Linux Foundation.
-
Hyper-V virtual Fibre Channel opens new doors
Hyper-V 3.0 allows VMs to connect to a SAN through a virtual Fibre Channel adapter, making even more servers good candidate for virtualization.
