/PRNewswire/ -- US-Yellow (
) is an independent yellow page publisher with consumers referring to Yellow Pages more than 15 billion times a year, with Yellow Pages a strong revenue producer in addition to the company's online and CD directory products. US-Yellow is a top resource for finding information online, in addition to its print directory and directory on CD.
US-Yellow operates a database-heavy IT infrastructure with multiple large SQL databases as well as Microsoft Exchange, PostgreSQL, and custom SAP applications. It recently undertook a major IT upgrade, adopting server and desktop virtualization platforms for the first time and making the transition from local server-attached storage to a high-availability Storage Area Network.
, IT Director at US-Yellow, was well aware of the storage challenges of a virtualized environment, such as the I/O blender effect of server virtualization and the extreme I/O demands of a Virtual Desktop Infrastructure deployment. To mitigate the I/O challenges of a virtualized infrastructure, Croxton sought out a flash-assisted storage solution but was frustrated by what he found.
"I was looking for SAN storage that I felt comfortable using both for production servers and VDI at the same time," he said. "But after speaking to several larger vendors I realized they either did not have an applicable solution, or their solution was far beyond my price range."
Croxton narrowed his choice down to commercial SSD-hard disk hybrid arrays from Nimble Storage and Tegile Systems (
). The decision was an easy one, he said, with Tegile offering better hardware, better pricing, more storage capacity (Tegile Zebi arrays boast almost a 4x flash capacity advantage per array compared to Nimble), and an honest, up-front sales process with excellent customer service.
Tegile's Zebi arrays bring a new approach to high-performance network storage with an innovative hybrid design that leverages the high performance of SSDs and the low cost-per-terabyte of capacity hard disk drives. The Tegile storage array delivers up to seven times the performance and up to 70% less capacity than legacy arrays. And unlike legacy arrays where any additional storage services require additional license fees, everything needed is built into the Zebi arrays, with a full range of storage services, including backup snapshots, remote replication, inline compression and data deduplication, application optimized templates for fast and easy storage provisioning and one-click deployment of virtual machines and virtual desktops.
