4 Tech Innovations That Improve Data Center Scalability

In today's business environment, companies are expected to grow quickly. This means their data centers must grow quickly, too. These four technological advances will help firms scale up -- and down, when necessary -- so growth doesn't turn into a bad thing.

CIO — Growth is normally a boon for any business. Servers hum faster when an ecommerce site attracts more customers (and more credit card transactions). When storage requirements for a new business that handles documentation for large companies suddenly escalate, executives high-five each other.

Data Centers

Scaling can be so costly, though, that fast growth isn't always a positive. Fortunately, new technologies can help a company ramp up quickly and efficiently, removing some of the pain of having to expand a data center. Instead of being faced with a major capital outlay that offsets new revenue, these innovations make the impact of scaling up a data center to meet demand less of a drain.

1. Modular Data Center Additions — But Not Modules

Most large companies know they can turn to Microsoft, HP and others to purchase entire data center modules. They provide a way to scale quickly, but usually a high cost.

Tate Cantrell, the CTO for British-based Verne Global, has a data center in Iceland that uses a modular approach — but the company doesn't have to add a module with hundreds of servers.

A new addition might consist of multiple racks and as few as 30, assembled remotely so that the cooling systems, power, cabinets and servers are all ready to go by the time they are installed. (The company can also install racks with up to 10,000 servers for larger companies.)

One key component: A power busway that provides greater flexibility for adding modules. Major electrical manufactures, including Siemens, Snyder, PDI and Universal Electric, offer busway solutions, Cantrell says. Verne Global standardized on Universal Electric Starline infrastructure for its modular data centers, he says, given the company's track record and its monitoring options, which let the company provide "very granular feedback" to customers.

2. Power Enterprise Pools: 'Elastic Capacity'

One challenge in scaling a data center is knowing when to invest in servers and how many to add. There are often spikes in demand, but it's difficult to predict when they will occur — and what to do when you don't need the extra capacity.

One answer: Enterprise Pools, a scaling infrastructure from IBM that works with the IBM Power servers. "Demands for data application is driving clients to look at continuous availability," says Steve Sibley, the director of IBM Power Systems. "When new apps roll out, they need to be able to scale rapidly or recover IT resources and scale down. There needs to be an elastic capability similar to the cloud and a way to not overpay for capabilities."
