Introduction
Hitachi AMS 2100/2300 Storage System Hardware Guide
In the AMS2100 with a 4 Gbps Fibre Channel connection, the array provides
high-speed data transfer between the host computer and the array. The
maximum speed is 400 MB/s for one port. Higher throughput can be
obtained, even when accessing multiple devices connected on the same
Fibre Channel loop.
The array supports open system operations and shortwave multimode
optical cables. With these shortwave Fibre Channel cards, the AMS2100/
AMS2300 can be located up to 300 meters from the open-system host.
Fibre Channel provides the following capabilities:
Fibre channel cable
The AMS 2100/2300 supports shortwave multimode optical cables. With
these shortwave Fibre Channel cards, the array can be located up to 500
meters from the open-system host. The array can use 50/125m, 62.5/
125m multimode fibre cable as defined in Table 1-3 , which lists the data
transfer rates at specific distances.

High-speed
Data Transfer Fibre
Channel With the 4 Gbps Fibre Channel connection, the AMS 2100
array can transfer data between the host computer and
the array at a maximum speed of 400 MB/sec on each
port. An 8 Gbps Fibre Channel connection is possible with
the AMS 2300 array. The system provides sufficient
throughput, even when accessing multiple devices
connected on the same Fibre Channel loop.
The AMS 2100 Fibre Channel interface is capable of
operating at data transfer speeds of up to 400 MB/sec.
The AMS 2100/2300 supports shortwave multimode
optical cables. With these shortwave Fibre Channel cards,
The AMS 2100/2300 can be located up to 500 meters
from the open-system host.

Number of
Connectable
Devices Fibre
Channel The array supports systems that can connect up to 128
Fibre Channel devices by using the Fibre Channel
interface and connecting Fibre Channel-SW.
Security
Function Fibre
Channel
and
Ethernet When the system is configured to connect multiple hosts,
a function is provided that rejects a boot by any host
except a specified host. This function can prevent the
access from an unauthorized host.
