E-Series Slashes Power & Space Footprint for Virtual Storage
Customer Overview

Facing dynamically growing volumes of data, the Corona-Norco Unified School District needed to consolidate its virtual storage and data protection environment for better management, infrastructure efficiency and cost control.

About Corona-Norco Unified School District


The Corona-Norco Unified School District is located approximately 45 miles southeast of Los Angeles in western Riverside County. The large district has 31 elementary schools, seven intermediate/middle schools, five comprehensive high schools, a middle college high school and three alternative schools. With an enrollment of over 53,000 students, it is the largest school district in Riverside County and the tenth largest district in California.

challenge: Provide a cost effective virtual storage for production data in VMware environment as well as secondary storage for backup and disaster recovery

With mounting volumes of data to protect, the Corona-Norco Unified School District was increasingly concerned with its existing Fibre Channel-based storage infrastructure and associated high cost per terabyte. The school district needed a more cost effective way to provide virtual storage for production data in their VMware environment as well as secondary storage for backup and disaster recovery. Compounding the challenge was the district’s need to optimize depleting rack space while lowering overall power consumption to further reduce costs.

With vital school production data to securely store, such as Exchange email and district databases, the IT staff for the Corona-Norco Unified School District began to seek an iSCSI-based solution that would conserve power and rack space while offering the enterprise-class performance and reliability they needed.

“With data center space at a premium, storage system density is also important to us,” said Brian Troudy, Network Manager, Corona-Norco Unified School District. “The Nexsan E60TM offers 60 drives in a mere 4U of rack space, which provides much greater density compared to alternatives. Furthermore, we can populate the system with a mix of SAS and SATA drives to align storage performance with application requirements.”

solution: NEXSAN E60 STORAGE SYSTEM WITH AutoMAID®

The Corona-Norco Unified School District solved all its challenges with the Nexsan E60 storage system. The system was selected for its performance, density and value. Corona-Norco also benefitted from the system’s unique power management features, providing up to 87% energy savings.

The school district quickly and effectively consolidated production data in their VMware environment and further enhanced its data protection strategy with the Nexsan E60, which includes 40 SAS drives to provide primary storage for Exchange, database and other production data. An additional 20 SATA drives are used for disk-based backup for complete protection of the school district’s information. All of this storage capacity fits in a compact 4U of rack space for superior space efficiency. Delivering further value for the growing school district, the E60 features Nexsan’s power efficient AutoMAID technology for low power consumption and data center maintenance costs.

results: flexible, high density and high performance platform for both primary and secondary storage requirements in a single storage enclosure

The Nexsan E60 has given the Corona-Norco Unified School District the flexible, high density and high performance platform it needed for both its primary and secondary storage requirements in a single storage enclosure. In addition, the school district is seeing up to an 87% reduction in energy consumption without any performance compromise – a result that is delivering significant operational cost savings.

“We needed a storage solution optimized for compatibility and performance in virtual environments. Nexsan fit the bill perfectly,” said Brian Troudy, Network Manager, Corona-Norco Unified School District.
