For ease of management, the disk drives are referred to by their physical location, the drive bay number.
Fibre Channel loop switches
The Fibre Channel loop switch acts as a central point of interconnection and establishes a fault-tolerant
physical loop topology between the controllers and the disk enclosures. The EVA5000 uses four loop
switches to connect the drive enclosures to the controller pair.
The FC loop switches provide the following features. For detailed information on Fibre Channel loop
switches, see
•
2.125–Gbps operating speed
•
Twelve ports
•
Half-width, 1U size
•
System and port status indicators
•
Universal power supply that operates between 100 to 250 VAC and 50 to 60 Hz
NOTE:
Each bezel covers two FC loop switches in a space of 1U.
HSV110 and HSV100 controllers
Two controllers are contained in each rack. Each controller is contained in a separate enclosure and
provides the features listed below. For detailed information, see
.
•
High-performance microprocessor
•
An Operator Control Panel (OCP)
•
Two 2–Gbps Fibre Channel-Switched fabric host ports
•
Four 2–Gbps Fibre Channel drive enclosure device ports (two device ports in HSV100 controller)
• Arranged in redundant pairs
• Data load/performance balanced across a pair
• Support for up to 240 disks with HSV110 and 56 with HSV100
•
1.25 GB cache per controller, mirrored, with battery backup
•
2–GBps FC cache mirroring ports with device port backups
•
Dual power supplies
In addition to managing the operation of the storage system, the HSV controllers serve as the interface
between the storage system hardware and the SAN. All host I/Os and all HP Command View EVA
management commands are processed by the controllers. Up to 18 drive enclosures are supported
by one controller pair.
NOTE:
To avoid impacting Secure Path operation, the internal identification of the controllers has been changed
for VCS v4.001. For VCS v4.001 and later firmware, the EVA3000 controller is now identified as
HSV101 and the EVA5000 controller is identified as HSV111.
