1.1.1 Product Introduction
This hardware manual briefly introduces the EonStor Fibre-to-Fibre RAID
subsystem. The F16F series comes with either six (6) or four (4) 4Gbps
Fibre channels on each RAID controller and supports sixteen (16) hot-
swappable Fibre hard drives in a 3U chassis. The series is built around the
5
th
-generation ASIC400 as the hardware RAID6 engine with a pre-installed
512MB cache memory or
another module of up to
2GB in size. The 4Gb/s
Fibre Channels are
interfaced through twelve
(12) SFP ports to facilitate
flexible, fault-tolerant host
or expansion links.
More significant is the loop switch architecture that eliminates LIP
overheads and improves FC loop performance. Six (6) embedded SATA
channels are used for cross-controller communications providing
exceptional bandwidth for synchronized cache operation.
The F16F series comes with redundant- or single-controller configurations
and the most advanced fault-tolerance features in the industry. Host and
drive channels are routed through separate I/O boards. Channels routed
through an I/O board are each from a different I/O processor to reduce the
chance of down time by component failure.
Dual-redundant, hot-swappable cooling and power supply modules protect
the subsystem from single point of failure. The modular nature of the
subsystem and the easy accessibility to all major components ensure the
ease of the subsystem maintenance.
