Is Water the Elephant in the Room for Data Center Efficiency?

Written by Joe Kozlowicz on Tuesday, July 22nd 2014 — Categories: Data Center Design, Green Data Center

As historic drought spreads in California, environmentalists are turning their attention towards potable water. While this isn’t an entirely new subject for conservation—we’re intimately familiar with water shortages here in Colorado and Wyoming—accelerating buzz and knowledge about climate change is making water shortages a hot topic, and data centers aren’t about to escape unscathed.

An investigative report in the Financial Times is shedding some light on the current water situation in industries around the world. The report includes a look at Google’s data centers, with Joe Kava, Google’s head of data center operations, quoted as saying that water is the “big elephant in the room” for data center companies.

4 Questions to Ask When Preparing for Disaster Recovery as a Service

Written by Joe Kozlowicz on Wednesday, July 9th 2014 — Categories: Cloud Hosting, Disaster Recovery

One of the easiest ways to get into the cloud—and one of the best, most essential uses of cloud infrastructure in general—is disaster recovery. This can be a low-cost method that will give you peace of mind and keep your business technology afloat if you lose primary hosting.

Depending on the recovery service level, you can prop up anywhere from 25% to 100% of your infrastructure to keep business continuity without a second location or colocation. Before you start implementing a disaster recovery plan, here are the essential questions you need to ask yourself and your IT team.

Saving Energy on the Other Side of the Rack: UPS and Transformer Efficiency

Written by Joe Kozlowicz on Wednesday, July 2nd 2014 — Categories: Colocation, Disaster Recovery, Green Data Center

A lot of the focus in the data center energy efficiency world is placed on cooling, and rightly so: cooling servers can consume as much as 37% of a well-designed data center, according to Emerson. But there are opportunities to improve efficiency on the other side of the rack, too. The power delivery systems, including Uninterruptible Power Supplies (UPS) and transformers, can deliver significant energy (and cost) savings.

How to Reduce Your VMware Disk Storage Use

Written by Joe Kozlowicz on Wednesday, June 25th 2014 — Categories: Cloud Hosting, Cloud Hosting, Cloud Storage, VMware, FAQs

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:

vCloud Director v5.1 Console Viewer Incompatible with Firefox v30

Written by Joe Kozlowicz on Tuesday, June 24th 2014 — Categories: Cloud Hosting, VMware

Update: vCloud 5.5 (which the gBlock Cloud was recently updated to) will work with Firefox.

As of June 2014, the newest release of Mozilla Firefox (30) is not compatible with the console viewer of the vCloud Environment. Firefox v30 can be used to navigate the environment itself, but when attempting to console into VMs, the browser experiences hang-ups and is ultimately unable to connect.

VMware is aware of this issue, which is caused by a code update with Firefox 30 that is not supported by vCloud Director 5.1. Unfortunately the latest VMware vCloud Director version is v5.5, so we do not expect support patches for minor issues in v5.1. Currently, Internet Explorer 11 (with compatibility mode ON, and Enhanced Security Configuration OFF) works when attempting to use the console from the vCloud Environment.

The current workaround for the Firefox issue is rolling back to a release before v30 (preferably v29, as it contains many of the same features and look as the newer version). To rollback Firefox to a previously compatible version, follow these steps:
