Page 47: Sfp Transceivers
Chapter 3: Subsystem Connection 3.1.3 SFP Transceivers SFP transceivers should typically have at least 4Gbps bi-directional data links, a laser transmitter (for fiber optic cables), low-profile LC connector, and a metal enclosure to lower the EMI. NOTE: LC connectors are small form-factor, fiber-optic connectors based on a 1.25-mm ceramic ferrule with a latching mechanism. - Page 48 Galaxy A16F-R2431 Installation and Hardware Reference Manual When selecting the number of hard drives that will be configured into a logical configuration, the mechanical performance of the hard disks should be considered. As shown below, if eight (8) members are included in a logical drive, this logical drive should be associated with a host ID, and accessed through a host channel making efficient use of the channel bandwidth.
-
Page 49: Fibre Channel Topologies
Chapter 3: Subsystem Connection 3.2.2 Fibre Channel Topologies The Fibre Channel standard supports separate topologies. They are Fibre Channel Arbitrated Loop (FC-AL) and fabric switch topologies. • FC-AL: This is the most common topology currently in use. Fibre Channel devices are all connected in a loop. Each device is assigned an arbitrated loop physical address (AL_PA). -
Page 50: Unique Identifier
Galaxy A16F-R2431 Installation and Hardware Reference Manual 3.2.6 Unique Identifier The unique identifier is a user-specified, 16-bit hexadecimal number that is used to generate Fibre Channel port names and node names. By factory defaults, each RAID controller is assigned with a separate hexadecimal number and the firmware then determines which unique identifier to use. - Page 51 Chapter 3: Subsystem Connection Figure 3-3: Host Ports Hubbed Together IMPORTANT: 1. One drawback of using the hub function is that the host ports looped together may not be connected to the N_ports on a fabric switch. When host ports are hubbed together, they are ideal for connecting other RAID enclosures and direct-attached servers with path redundancy while without the costs on expense of FC switches.
