Connection and Operation
This chapter outlines some basic rules you should follow when configuring a
storage system and introduces basic information about how to connect the
cabling and design a topology for the Galaxy 24bay RAID subsystems. You can
follow these sample topologies or use them as a guide for developing your own
unique topologies. A complete description of the power on and power off
procedures is also given in this chapter.
4.1 FC Host Connection Prerequisites
4.1.1 Choosing the Fibre Cables
It is recommended to apply Galaxy certified Fibre Channel transceivers and
optical cables. The Fibre host ports connect to Fibre Channel host adapters
(HBA) that features a 4/2Gbps transfer rate, SFP interface, and support for full-
duplex transfer, best interfaced through a 64-bit/133MHz PCI-X or higher speed
system bus. In order to bring out the best of your RAID performance, HBAs of
high speed interface are recommended.
WARNING!
All Fibre cables are sensitive and must be handled with care. To prevent
interference within a rack system, the cable routing path must be carefully
planned and the cables must not be bent.
