Reducing overhead, delivering ROI, and going green have all become business priorities in recent years. Data centers alone now represent more than 2% of total worldwide energy consumption, with growth rates of as much as 12% per year. That’s a huge chunk of megawatts spinning processors! Reducing energy consumption is not only an eco-priority, it’s also a business imperative as overhead costs rise.
Server vendors have delivered impressive gains with highly efficient, power-saving hardware. But there hasn’t been much discussion about how better software – tighter code and better algorithms – can deliver higher performance to reduce the need for server hardware in the first place.
With Future Ready CacheServe 7, Nominum invested in improving DNS, and performance results are impressive. We delivered a substantial increase to 2.4 MillionQueries per second. That’s a lot of DNS resolution capacity!
Top level, a single server could replace 10 or more legacy servers. Network topology and actual requirements for DNS capacity may reduce the number of servers that can be consolidated, but savings are still attractive for power and cooling in addition to space and staff. And DNS traffic continues to grow at a rapid rate – more than 30% in most networks so inevitably more DNS capacity is needed.
Back to the ROI of green. Benchmarks of centralized and distributed network architectures using CacheServe 7 showed OPEX savings of 54% and 36% respectively (SW and HW support, rack, power, cooling, management). Total Cost of Ownership was reduced by 34% in the centralized topology and 22% in the distributed topology. This includes the cost of commercial software licenses for Vantio CacheServe 7. There’s a difference in savings between the two topologies because in the centralized case more servers can be consolidated, which takes greater advantage of the massive capacity CacheServe 7 delivers.
Taking network architecture out of the equation, a single server starting at 200,000 QPS, growing at 30% per year with a 90% cache hit rate could last for more than 8 years. How green is that ($$$)?
Doing more with less is the essence of green business. With tight margins and slowing growth it’s even more important for service providers. Future Ready CacheServe 7 introduces many ways to do more. For instance, DNS data is a valuable resource that remains largely untapped. CacheServe 7 makes it simple to collect, aggregate, and visualize data so it can be used for operations, security and broader analytical purposes. A robust policy framework protects servers and networks and provides a platform for personalized subscriber services. There’s lots more.
