Update: Web-host company fully embraces solar

Correction: In the original version of this article, I mistakenly suggested that Greenest Host was the owner of the solar-powered datacenter I discuss. The facility belongs to AISO; Greenest Host is leasing a portion of the datacenter for its Web-hosting operation.

Additionally, I reported that Greenest Host is running 600 servers. They say they’ve reserved enough space to run as many as 600, though at the time of writing, they are unable to provide a specific figure.

I apologize for any confusion I may have caused.

Following the lead of other companies seeking to boast green credentials, San Diego, Calif.-based Greenest Host has set up its Web-host service in AISO’s 100-percent solar-powered datacenter. The facility is located in the inland desert of Southern California where its solar panels can soak up the sun year ’round.

The appeal of being a fully solar-powered company was strong for the company’s CEO Mike Corrales. “Personally, my core values tend to skew toward green application and green causes,” he says. “We wanted to make it really easy for end consumers and small businesses to be able to build their own Web sites in a way that coincided with their own personal value system.”

According to Phil Nail, founder of AISO, many organizations have been turning to his company’s hosting services for similar reasons. “We’ve seen a lot of that,” says Nail. “Even out of the U.K, they’re really coming out of the woodwork. A lot of companies have decided to resell our service.”

By day, AISO’s servers feed directly off the panels. By night, they get their power from batteries that store the excess solar energy. But the company has a backup plan. “[AISO.net] has a backup generator that runs on propane, just in case there is a shortage, or for some reason, we went 30 days in a row without sun,” says Corrales.

Inside the datacenter, AISO runs new AMD Opteron-powered servers, “which use 60 percent less energy and generate 50 percent less heat” than the previous generation, according to the company.

“[AISO] worked closely with AMD to make sure that we have the best possible solution for our green datacenter. Because of their willingness to literally work hand-in-hand through the entire design and development process of the datacenter infrastructure, [AISO] felt that AMD was and still is the only way to go,” says Corrales.

And, of course, AISO employs virtualization (from VMWare, specifically) “to reduce cooling and electrical requirements with a 30:1 ratio of virtual servers to physical servers.”

For cooling, AISO uses two Energy Star-compliant systems from Freus. The cooling systems monitor outside air temperature, according to the Greenest Host, and when it reaches 50 degrees or below, “they suck the outside air in, filter it, and direct it into the datacenter, thus saving electricity when it’s cool outside.”

Moreover, AISO employs redundant environmental monitors from APC. These act as smoke alarms, but they also monitor humidity and cooling levels. “In case of a cooling issue, our support staff is notified immediately. This ensures all servers are maintained in a cool environment, which will prolong the life of the servers,” according to the company.

The datacenter itself is built from steel and multiple layers of environmentally friendly insulation, the company says. The design keeps the cool air in and the hot air out, thus reducing the amount of energy necessary to run the facility.

AISO is also in the process of adding a green roof, which it says will reduce cooling and heating requirements by up to 50 percent. (A green roof, essentially, is a layer of soil and vegetation atop a building.)

Moreover, the company has a to-do list of other innovative and eco-friendly projects, according to Nail. “We are adding an underground water-storage tank to recycle grey water. Next, we are installing a new solar-panel automated-washing device we created. This will automatically wash the solar panels each morning, and all excess water will be filtered back into the storage tank. We’ll also be using the storage tank water to water our landscape,” he tells me via e-mail.

Given the green wave that’s swept the business world, Corrales anticipates organizations will be lured by the eco-friendly nature of the service. “We can have an ethically superior choice available for people, but they don’t have to sacrifice higher performance,” he says. “Our pricing is pretty in line with all the major standard Web-hosting options out there.”

Greenest Host will open to the public on Aug. 1. For more information, go to greenesthost.com. For more information about AISO, go to aiso.net.
