• RAID levels 0, 1, 0/1, 3, and 5 (RAID level 3 supported on Windows NT and Windows
2000 only)
• EMS hardware monitoring (HP-UX only)
High Availability
High availability is a general term that describes hardware and software systems that are
designed to minimize system downtime — planned or unplanned. The Disk Array FC60
qualifies as high-availability hardware, achieving 99.99% availability.
The following features enable high availability:
• Hot-swappable, high-capacity, high-speed disk modules
• Dual Fibre Channel arbitrated loops (FC-AL) connection to the host
• Redundant, hot-swappable, fans and power supplies
• Support for RAID 1, 0/1, and 5
• Remote monitoring and diagnostics
• EMS Hardware event monitoring and real-time error reporting (HP-UX only)
Note The Disk Array FC60 is designed to operate with either one or two controller
modules; however, for data integrity and high availability it is highly
recommended that dual controller modules be installed.
Scalable Storage Capacity
The Disk Array FC60 is designed to provide maximum scalability, simplifying the process
of adding storage capacity as required. Storage capacity can be added in three ways:
– By adding additional disk modules to a disk enclosure
– By adding additional disk enclosures to the array
– By replacing existing disk modules with higher capacity modules
The controller enclosure supports up to six disk enclosures. Each disk enclosure holds up
to ten disk modules in capacities of 9.1 Gbyte, 18.2 Gbyte, 36.4 Gbyte, or 73.4 Gbyte. The
minimum configuration for the array is one disk enclosure with two 9.1-Gbyte disk
modules. The maximum configuration is six disk enclosures with ten 73.4-Gbyte disk
