1.6 Gigabit Fibre Channel Adapter AIX 4.3.2 supports the new Gigabit PCI adapter for Fibre Channel Arbitrated Loop (FC-AL) connectivity on RS 6000 S70/S7A machines. The adapter has an expected availability date of March 26, 1999. It uses a shortwave over optical fibre cable for a distance of up to 500 meters. With the use of optical fiber cabling, this adapter allows users to establish a high speed network for local and remote storage. Fibre Channel Arbitrated Loop (FC-AL) began as the Fiber Channel Standard (FCS) originally developed by IBM as a communications technology for computer systems. FC-AL provides a high-speed interconnect running at 100 MB/s for a single loop, 200 MB/s for dual loop-theoretical. FC-AL is an arbitrated loop technology that allows only one-device access to the bus for I/O operations. This adapter is supported on AIX 4.3 with APAR IX81852. This adapter has the following characteristics: • One initiator capability over an optical fiber link, one Gigabit Fibre Channel Adapter per loop • Transmitting distance at 500 meters when using 50/125 micron cable and 175 meters when using 62.5/125 micron cable • Data rate throughput at 100 MB/s burst, 75 MB/s sustained • 25 MHz to 33 MHz clock speeds • 132 MB/s peak data transfer rate • 32-bit PCI Bus Master Mode DMA, 32 bit PCI Bus Slave Mode interface • Slave Mode supports medium device select timing • 32-bit PCI adapter with 64-bit addressing capability • Transmitting rate of 1062.5 MB/s • Short PCI form factor (6.875 x 4.2 inches) • Bus master, scatter/gather architecture • Selectable big/little endian • GLM medium adapter allows future use of copper or longwave optics • Supports 2048 exchanges • 6 KBx36 frame buffer (4 KB receive, 2 KB transmit) • 128 KBx32 SSRAM for processor memory • 512 KB Flash EPROM that contains microcode • 233 MHz ARM processor as the adapter controller • Support for 5.0 Volt or 3.3 Volt electrical signaling • Estimated performance is 5000 to 9000 SCSI 4 KB OP/s • PCI Local Bus Revision 2.1 compliant • No IPL/Boot support 10 AIX Version 4.3 Differences Guide
The Gigabit Fibre Channel adapter provides an attachment of one or two external RAID subsystems to one or two hosts. The two host configuration supports HACMP. Single host configuration with two adapters support fail-over from one controller to the other. A follow-on product will provide 4-way attachment. The new adapter supports connectivity to the IBM 2102-F10 Fibre Channel RAID Disk Array subsystem with IBM 2102-D00 Storage Drawers through the optional IBM 2103-H07 Fibre Channel Hubs. The supported configurations include: • Point-to-Point In this configuration, an adapter is connected directly to one RAID subsystem using the shortwave cable. Even though it is physically a point-to-point configuration, it logically appears to be a private (closed) arbitrated loop. Maximum distance between the adapter and subsystem is 500 meters. • Private Arbitrated Loop In this configuration, one hub is attached to the adapter through the shortwave cable. The hub is a non-intelligent device. It is considered to be part of the cabling and is not recognized by the adapter as a device. From the hub, up to two RAID subsystems can be attached. Although Gigabit Fibre Channel and Gigabit Ethernet could use similar physical media, such as fiber optic cable, Gigabit Fibre Channel and Gigabit Ethernet operate at different speeds and protocols. For example, Fibre Channel operates at 1.0625 Gbps, while Gigabit Ethernet operates at 1.25 Gbps. Fibre Channel protocol is optimized for the low-latency and high reliability required by storage, while Gigabit Ethernet protocol is optimized for LAN.
