Open-systems host attachment with Fibre Channel adapters
You can attach a storage system to an open-systems host with Fibre Channel
adapters.
The storage system supports SAN speeds of up to 16 Gbps with the current 16
Gbps host adapters, or up to 8 Gbps with the 8 Gbps host adapters. The storage
system detects and operates at the greatest available link speed that is shared by
both sides of the system.
Fibre Channel technology transfers data between the sources and the users of the
information. Fibre Channel connections are established between Fibre Channel
ports that reside in I/O devices, host systems, and the network that interconnects
them. The network consists of elements like switches, bridges, and repeaters that
are used to interconnect the Fibre Channel ports.
FICON attached IBM Z hosts overview
The storage system can be attached to FICON attached IBM Z host operating
systems under specified adapter configurations.
Each storage system Fibre Channel adapter has four ports or eight ports,
depending on the adapter type. Each port has a unique worldwide port name
(WWPN). You can configure the port to operate with the FICON upper-layer
protocol.
With Fibre Channel adapters that are configured for FICON, the storage system
provides the following configurations:
v Either fabric or point-to-point topologies
v A maximum of 64 ports on DS8884F storage systems, 64 ports on
DS8884 storage systems, and a maximum of 128 ports on DS8886,
DS8886F and DS8888F storage systems
v A maximum of 509 logins per Fibre Channel port
v A maximum of 8,192 logins per storage system
v A maximum of 1,280 logical paths on each Fibre Channel port
v Access to all 255 control-unit images (65,280 CKD devices) over each
FICON port
v A maximum of 512 logical paths per control unit image
Note: IBM z13
®
and IBM z14
™
servers support 32,768 devices per FICON host
channel, while IBM zEnterprise
®
EC12 and IBM zEnterprise BC12 servers support
24,576 devices per FICON host channel. Earlier IBM Z servers support 16,384
devices per FICON host channel. To fully access 65,280 devices, it is necessary to
connect multiple FICON host channels to the storage system. You can access the
devices through a Fibre Channel switch or FICON director to a single storage
system FICON port.
The storage system supports the following operating systems for IBM Z hosts:
