It’s easy to provision additional VMs and increase resource commitment from your overall resource pool using the vSphere web portal. Maybe too easy. If you overstretch your resources, some features like High Availability failover may not function as planned. HA keeps your VMs from failing by pooling VMs and hosts in a cluster, relaunching failed VMs on alternate hosts.
Overcommitting resources can also lead to general performance problems, so it is in your best interest to use Admission Control to keep a close watch on overall capacity. Another reason? You might be trying to power on new VMs, only to run into errors as you exceed your Admission Control rules. Tweaking them can save you from buying additional host resources.
This post will introduce the concepts of slot sizes and configuration of Admission Control to allow more VMs to move between hosts when you have turned on High Availability in vSphere/vCenter.
We’ve been cloud-native since the beginning, offering VMware-powered virtual hosting for almost ten years. In fact, our very first EMC backend storage array is now sitting in the lobby of our Cheyenne headquarters.
Of course, we couldn’t stay stagnant with our cloud offerings (you’d notice if that old storage array was still powering your cloud, trust us). The hardware, software, and facilities powering the gBlock cloud have undergone a variety of upgrades over the past decade, and the latest set is big enough for us to dub it officially the gBlock Cloud 2.0.
So what’s new in the Green House Data cloud? Let’s dive into the benefits customers can receive when the migrate to this new and improved platform.
Looking to improve your workflow and be more efficient when you’re managing virtual machines in the VMware vSphere Web Client? Keyboard shortcuts not only make you look like a wizard when you’re showing someone how to perform an operation, they also make your daily admin life a little bit faster and easier.
While you may be used to the desktop client, the web client also includes some handy features that can help speed up your workflow. Below are some of our most-used keyboard shortcuts and tips for quickly navigating the VMware vSphere web client.
Here at Green House Data, our technicians are constantly working hard behind the scenes to improve the customer experience in our cloud products. We’ve recently completed a round of upgrades to bring you the latest features and bug fixes to our gBlock Cloud platform.
Here are some of the newest features that are available to you today, including improved web portal access, new disaster recovery features and interoperability with AWS and Azure, and more.
When designing the architecture for your SQL Server virtualized on VMware vSphere, your requirements will determine which SQL availability or vSphere availability features you should use. There are several availability features packaged with SQL server before you even get to vSphere features like Distributed Resource Scheduler, High Availability, Fault Tolerance, or vMotion, each of which have their own considerations when interacting with SQL.
To get started, you’ll want to ask yourself a few questions about your SQL deployment.
“Can my application run in the cloud?”
It’s a question we get more frequently than you might think — and the answer is almost always yes. Just yesterday, we got a web chat from an individual who wanted to know if a cloud server could run his e-mail server, SMTP-based, with PowerMTA, or if he would need a dedicated option. Mail servers are frequently run on virtual machines, so this configuration should pose no problem as a cloud server.
There are thousands of applications, running on a wide variety of operating systems, that play nice with VMware virtualization platforms (the basis of the gBlock cloud). Here are four hybrid cloud use cases to get you started.
You’re probably familiar with the kind of performance issues inherent in antivirus/antimalware tools. Anyone who has used a PC when the antivirus scan boots up can attest to sluggish performance. The same issues rear their head when using antivirus in a virtual environment – but virtual machines come with their own set of wrinkles.
Antivirus software can be installed either on the VM itself or on the host. Depending on your approach, you’ll want to consider these key factors to maximize performance.
Cloud infrastructure is all about providing the right amount of resources for your applications at any given moment. Overprovisioning might be wise for performance-oriented apps, but generally “right-sizing” is the best way to maximize your budget, especially as most IT departments face efficiency and cost struggles.
By being proactive about managing your virtual machine resources and halting underutilized or “zombie” VMs, you can free up those resources either to be decommissioned or reassigned to other uses.
You’ll want to adjust VM size to reclaim overprovisioned VMs, clean up idle or turned-off VMs, and resize VMs that are stretching their current resources beyond acceptable performance. Here’s how to practice active capacity management.
Containers are on the rise, with VMware integrating them into the vSphere platform. What started seemingly as a competitor to virtual machines has proved to be just another tool in the virtualization box available to administrators beyond software testing and development, as enterprises and mid-market companies of all sizes begin to implement containers alongside (and inside) their VMs.
Once you read a bit about the benefits of containerization, you may be curious about trying some out in your environment. But before you start spinning up containers left and right, make sure you’re using the right tool for the job. Containers certainly have their advantages, but there are many applications where a virtual machine will be more effective. Here’s how to decide.
Snapshots are a convenient way to get a “moment in time” copy of your virtual machines. They should not be used as a primary method of backup, as they generally work as a record of changes made—they depend on the original virtual machine in order to roll back. They’re great for testing as they save the virtual machine settings, the state of the virtual disks, and the contents of memory, if you choose.
Snapshots are useful before you make significant configuration changes, upgrades, patches, or new software installations. Any time you’re adding or changing your virtual environment enough to think, “Hmm, I wonder if this will affect my production applications,” it’s probably an opportune moment to take a snapshot.
Here are eight tips to make the most of your snapshots.
