Sprint is one of the largest telecommunications companies in the United States, currently serving over 54 million wireless and wireline customers. As an organization, Sprint has three main goals: strengthen and grow the Sprint brand; generate revenue to support and sustain long-term growth; and provide excellent customer experience and satisfaction. Sprint’s IT organization consists of 4 datacenters with 6,000 hosts, and a 30 petabyte SAN environment.
After noticing increasing performance challenges across their infrastructure, Sprint turned to Virtual Instruments to help pinpoint and solve some very specific issues. And VirtualWisdom did just that—and very quickly.
“Within an hour of turning it up, we started to see SAN flow problems that we’ve never been able to isolate before. Specifically, we found a buffer-to-buffer credit starvation issue that had impacted our dot-com environment,” said Josh Morton, vice president of IT services at Sprint.
Once VirtualWisdom was implemented across their entire storage infrastructure, problem-solving and troubleshooting became a breeze. “We had a VMware environment that had been having chronic performance problems, and with VirtualWisdom we were able to identify and isolate that problem, and improve response time by over 90%,” said Morton.
But it didn’t just stop there.
