Virtualization Performance Monitoring: vCPU Demand, Usage, and Contention

Written by Joe Kozlowicz on Wednesday, June 13th 2018 — Categories: Cloud Hosting, VMware

When managing a virtualized environment you’ll naturally want to monitor your compute resources such as memory, CPU, storage, and bandwidth in order to keep an eye on any possible performance issues.

We’ve covered monitoring before – like how much information to collect, how granular you need to get, how to check load averages, and configuring vSphere Alarms for resource consumption. Today we’re taking a closer look at CPU performance monitoring in particular.

Often times the CPU is the first potential culprit to check when you encounter a struggling virtual machine. Learn the differences between CPU metrics, some common problems, and best practices for provisioning CPU cores in this blog.

Don’t Turn NUMA NUMA Yay into NUMA NUMA Nay: Checking Your Virtual Machine NUMA Configuration

Written by Joe Kozlowicz on Thursday, May 10th 2018 — Categories: Cloud Hosting, VMware

NUMA architectures allow for greater scalability, which is of course great for building cloud data centers. But if your virtual machines aren’t configured correctly, NUMA can cause performance degradation in VMware virtualized servers.

Here’s an overview of what NUMA is, why it’s useful for cloud computing, and how to address it when configuring your VMware cloud server.

Why We Added Azure Management After a Decade of VMware Expertise

Written by Thomas Burns on Friday, March 30th 2018 — Categories: Cloud Hosting, Cloud Storage, Hybrid Cloud, Cloud Hosting, Cloud Storage, Microsoft, VMware

Green House Data announced the addition of Azure cloud to our stable of managed cloud services this week. For some, this may come as a bit of a shock. We’ve been a VMware shop since the company was formed, with the gBlock Cloud hosted within our data centers on the vSphere platform.

We’ll continue to offer our own hosted VMware cloud as well as VMware cloud management on behalf of our clients, but we’ve expanded our scope to include Azure managed services. There are a number of reasons for this shift in strategy, which ultimately allows clients a wider breadth of service options to best suit their IT infrastructure goals.

Staying on Top of Resource Commitment with VMware High Availability

Written by Joe Kozlowicz on Thursday, October 12th 2017 — Categories: Cloud Hosting, Cloud Hosting, VMware, Documentation

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.

Introducing the gBlock™ Cloud 2.0: What’s Improved in the Green House Data Cloud

Written by Josh Larsen on Friday, July 28th 2017 — Categories: Cloud Hosting, Cloud Storage, Hybrid Cloud, Cloud Hosting, Cloud Storage, VMware, Product Information

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.

How to Choose an Availability Strategy for SQL Server on vSphere

Written by Joe Kozlowicz on Tuesday, January 17th 2017 — Categories: Cloud Hosting, Microsoft, VMware

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.

Four Hybrid Use Cases to Get Your Head in the Cloud

Written by Joe Kozlowicz on Wednesday, January 11th 2017 — Categories: Cloud Hosting, Hybrid Cloud, Cloud Hosting, Cloud Storage, VMware

“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.
