EVA5000 HSV110 controllers
Two high-performance HSV110 controllers are contained in one EVA5000 rack. Each controller is
contained in a separate enclosure and features:
• High-performance microprocessor
• An Operator Control Panel (OCP) for easy operation
• Two 2-Gbps Fibre Channel-Switched Fabric host ports
• Four 2-Gbps FC-AL device ports
• Arranged in redundant pairs
• Data load/performance is balanced across a pair
• Supports up to 240 disks (12 0 disks per pair)
• 1-GB cache per controller, mirrored, with battery backup
• 2-Gbps FC cache mirroring port with device port backups
• Dual power supplies
The controller is the interface between Command View EVA and the Enterprise Virtual Array (the interface
between hosts and disks). It is the interface to your data and performs I/O correctly and reliably. Up to
18 drive enclosures are supported by one HSV110 controller pair.
Each controller pair consists of two controllers. Figure 7 shows the controllers as they reside in the
storage system.
