24 24 Then next innovation is software-based. CLARiiON Virtual Provisioning allows users to present an application with more capacity than is physically allocated to it in the storage array. Virtual Provisioning simplifies and accelerates processes and delivers “just-in-time” capacity allocation and improved utilization. Virtual Pools are easy to create whereby customers simply assign a name, select the drive types and capacity amounts, and choose the appropriate RAID level for protection. To quickly allocate capacity, the user simply selects a pool, chooses the host, and specifies the virtual capacity amount to allocate. Once capacity is allocated, CLARiiON Virtual Provisioning has capabilities to monitor the usage versus pre-set thresholds and automated alerts so that pools can be expanded non-disruptively. CLARiiON Virtual Provisioning supports advanced software capabilities including Virtual LUN, Navisphere QoS Manager, Navisphere Analyzer, and SnapView. The combination of the proven CLARiiON technology and the new capabilities of the CX4 series provide customers with unique energy efficiencies in midrange storage. This is critical for customers as many are running out of power in their data centers. The new energy efficient capabilities include: support for Flash Drive technology which represents 98% better efficiency per I/O when compared to FC disks, Low-power SATA drives which consume 32% less energy than traditional SATA drives, Policy-based spin down which reduces energy for inactive drives while maintaining online access, and CX4’s adaptive cooling feature that dynamically adjusts cooling based on the system’s activity level. 26 EMC has also introduced 1 TB Low Power SATA drives to further extend cost-effective, tiered storage options within the CLARiiON CX4 series. This new Low Power drive delivers the highest density at the lowest cost and requires 96 percent less energy per terabyte than 73 GB 15K rpm Fibre Channel drives. And when co
