Fibre Channel Connection

and SAN Connectivity

Fibre channel on BS2000/OSD s series business servers


Fibre Channel

ESCON

FC

Every 2-3 years, doubling of server and disk subsystem performance.

Since the transition from Type 2 to Type S, nothing has happened in the I/O area!

Innovation Fibre Channel

high performance

low cost

The real innovation for BS2000 customers


BS2000 offering for S customers

Systematic implementation of our open system strategy

Hardware – SAN connection - openness

High-performance connection

Fibre Channel on /390 systems is a highlight for the S architecture and a

unique selling point

Real alternative to IBM’s FICON

not a “proprietary” connection, but standard technology

2


Mainframe features in the SAN

Customer benefits:

Up to 8 paths to a Device

Redundancy for failure scenarios

Dynamic load balance

One FC connection can be used for several guest systems (VM2000)

Efficient utilization of the HW resources by server and Storage subsystem

Such Features are standard for mainframe systems

– in open systems area not available yet
