UK-based provider of IT solutions enhances network monitoring for customers, increasing per-server processing capability by 6x
London-based Modrus Limited provides hosting, cloud, and virtual IT solutions for its customers. Founded in 2004, Modrus is an experienced supplier of outsourced computing and telephony solutions, as well as an industry-respected retailer of networking and VoIP equipment.
Modrus uses Zenoss Network Management software to spot network issues before they ever become problems for its customers. But as its customer base and corresponding network load grew, its hosted Zenoss system servers began to slow.
Modrus’s Managing Director, Edward Armitage described the difficulty: “Zenoss generates a significant amount of disk I/O. Our systems were running close to 100% capacity, so any small performance issue would massively impact the monitoring system.”
To ensure slowness never affected the company’s quality of service, Mr. Armitage promptly began looking for a solution that could deliver the following:
A Cut Above: Providing Enterprise-Level Reliability
After researching options, Mr. Armitage determined Fusion ioMemoryTM solutions had a proven track record for reliability: “We identified Fusion ioMemory use cases through Internet forums that equaled or exceeded our performance requirements, and which had been running for many years.”
Making Performance Problems and Server Footprint Disappear
The data load on the system had exceeded the capability of Modrus’s previous servers. Mr. Armitage was concerned about how to handle future growth while maintaining the best-in-class monitoring service they provided to their customers.
Maximizing Performance per Server
With those goals in mind, Mr. Armitage added a Fusion ioMemoryTM ioDrive Duo® 640GB card to one of its Zenoss servers and moved the Round Robin Database (RRD) data onto it. He found that the performance problems disappeared. Mr. Armitage said, “We processed a total of 11,400 data points per minute across three servers in the old system. With an ioDrive Duo card, we can process 24,600 data points on just one server. This tells me that one server is processing six times the data of the old configuration.”
The chart below shows the server performance improvements.

Driving Costs Down Now and In the Future
The three-to-one footprint consolidation the ioDrive Duo cards enabled had a significant impact on Modrus’s current hardware costs. “SanDisk has really reduced our costs. We’ve managed to decommission some hardware and simplify our monitoring platform,” Mr. Armitage explained.
He also pointed out that these cost savings would continue well into the future: “The SanDisk-powered server is only running at 25% capacity. Not only are we now delivering a better quality of service to our customers, but our workload can increase significantly before we need to add more hardware.”
The chart below shows the performance density improvements:
Less Administration, More Value-added Work
Modrus realized an additional cost benefit by implementing Fusion ioMemory solutions: the simpler, more powerful system was much easier to maintain.
Mr. Armitage said, “We spent a great deal of time coaxing the old system along. We were spending an average of an hour a day, ensuring that the system didn’t lose data. The new infrastructure is significantly better. Our guys now spend less than an hour a week monitoring the system.”
This freed staff to spend time on more value-added activities. Mr. Armitage added, “In essence, the engineer has moved from a daily tactical role to a more strategic role, where he has the time to look for ways we can improve our infrastructure monitoring.”
Implementing Fusion ioMemory solutions gave Modrus the following benefits:
Mr. Armitage concludes, “We’re now considering using the ioDrive Duo cards elsewhere because it’s a guaranteed fix. You know you can get a performance improvement with an ioDrive Duo card.”
