Scalability; Performance Reporting And Monitoring - Acer HDS AMS200 Reference Manual

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.

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.

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.
