Acer | HDS AMS200 User and Reference Guide 3
Ethernet: With the 1 G bps Ethernet connection, the subsystem can transfer data between
host computer and the subsystem at a maximum speed of 100 M bytes/s per port via a
network. Enough throughput can be obtained even when having multiple access to the
multiple devices connected to the same network loop.
„
Cable
Fibre Channel: With Fibre Channel, the subsystem can be located up to 300 meters from the
host.
Ethernet: With Ethernet, the subsystem can be located up to 100 meters from the host. The
subsystem can be installed in the location far from the host.
„
The Number of Connectable Devices
Fibre Channel: The AMS200 subsystem enables you to construct a system which can connect
up to 126 fibre channel devices by using the fibre channel interface and connecting the FC-
AL and the FC-SW.
„
Security Function
Fibre Channel and Ethernet: When the system is configured to connect multiple hosts, a
function is provided which rejects a boot by any host except a specified host. This function
can prevent access from an illegal host.
1.1.3 Scalability
The architecture of the AMS200 enables the user to scale the subsystem to meet a wide
range of capacity and performance requirements:
„
You can construct a variety of systems; for example, a system with 15 disk drives can be
configured using a single RKS, or a more complex system can be set up using the
maximum of 105 disk drives, expanded by connecting up to 6 RKAJs/RKAJATs to the RKS.
„
Up to 15 spare disks can be set up in any location. Use the system effectively by
configuring each spare disk in a disk drive slot left unused due to system construction.
„
From the host computer, the subsystem can be used as a single large-scale disk drive or
as 512 logical disks (LUs) maximum.
1.1.4 Performance Reporting and Monitoring
The Storage Navigator-Modular program provides the capability to either monitor the disk
array in real-time or to collect historical data regarding the performance of the disk array.
