If you’ve spent much time around data centers, you’re likely familiar with load balancing. But if you haven’t, it’s a vital concept to understanding how to keep your infrastructure available to all of your users, while also maximizing the efficient use of your computing resources. Even if you’re familiar with load balancing, there are some recently released tools and similar concepts that we’ll cover in order to share your workloads across your servers — and even across the country.
Disaster recovery is a vital part of any backup strategy, but sometimes it's not clear how it differs from your everyday backups. A Microsoft survey discovered most organizations experience 4 or more disruptions each year with an average cost of $1.5 million an hour. To fight the high cost of downtime, 43% of IT professionals are planning to invest in or improve their business continuity with cloud-based disaster recovery, citing reduced costs and expanded coverage as their primary reasons, according to IDG.
With disaster recovery (DR) taking such a high priority in the IT world right now, we asked our resident expert Josh Larsen, Sales Engineer, to answer some of the most common DR questions.
If you’re running an open source server in the gBlock cloud, you are probably already familiar with a LAMP stack. If you haven’t used one before, LAMP is a web application and deployment stack that is very common and simple to install and use on your virtual machines. This blog will walk you through a LAMP installation so you can get development cranking.
One of the more ingenious forms of computer hacking in the past decade is the development and implementation of ransomware. Ransomware is a type of computer malware which when infected into a user’s computer restricts access to that computer and demands a form of ransom be paid before the system can be accessed. The ransom can range from $100 to upwards of $10,000.
Systems Administrator Jeremy Smario explains what ransomware is and how can you avoid data loss or the huge expense of freeing your files from its grip in this post.
Amazon is building a wind farm. Apple has tens of megawatts of solar power. Google builds in Nordic countries and sources power from hydroelectric facilities. Other providers started giving out Renewable Energy Credits to cover customers’ electric costs (and they aren’t the only ones buying RECs and PPAs—but this blog post isn’t just about Green House Data).
Despite the recent trend of data center operators going green, does the IT industry really care about the environmental footprint of their data center? According to our recent survey results, the answer is a resounding…maybe.
We polled 166 IT professionals, from system administrators to the CTO. All but two had input into IT and infrastructure decision-making at their company. What they had to say was surprising. In a nutshell, it makes smart business sense to have a green data center, because it saves on operating costs. Whether IT departments consider energy efficiency or sustainability when evaluating service providers is up for debate.
Uh-oh. A virtual machine is down. Or a user accidentally deleted a project they’ve been working on for weeks. Or an application has become corrupted. Or…you get the picture. Good thing you have virtual machine images ready to go in storage (you can create backups using the VMware Consolidated Backup tools, which takes your latest snapshot as a basis for the full image backup). Now all you need to do is decide on a restoration method.
For a full VM restore, you’ll use VMware Converter, while for file-level restoration you’ll use VMware Consolidated Backup (VCB), which also has the choice for centralized, per-group, and self-service restoration.

As you grow more comfortable in the cloud, you’ll likely find more and more of your applications making the transition to your VMware environment even as your existing virtual apps continue to grow. Add backups or DR to the list and your storage use might start to get a little out of control, especially with linked clone virtual desktops or snapshot trees that save multiple VM states.
Storage costs can add up, so you’ll want to stay proactive in maximizing disk usage and eliminating inefficiencies. There are a few ways to maximize storage and reduce disk sizes depending on the VMware product and deployment:
Public media in VMware vCloud is organized in catalogs. Administrators can create and organize files in catalogs for public users. In vCloud Director, media can be virtual machine and vApp templates or ISO images used as boot and installation disks. Media images stored in catalogs can be attached to vApps and mounted by virtual machines. This blog post will take a look at how to upload and use public media.
Since the launch of vSphere 3.5, ESXi has been the default hypervisor for VMware environments. Here’s a quick description of how to get your ESXi environment up and running.
ESXi uses approximately 2 GB of space and 1 GB of RAM. It requires a 64-Bit x86 CPU, 2 GB RAM and at least a 1 GB network card. There is a free version of ESXi but it lacks many of the features of a licensed version.
