Controller Connectors (With Sas Host Port Adapters); Enclosure Id Settings; Working With Sas Cables - IBM DS3500 Installation, User's, And Maintenance Manual

Internet Protocol version 4 (IPv4) and IPv6, and have the advanced
networking functions of jumbo frames, IEEE 802.1p, and virtual local area
network (VLAN) support.
Drive expansion port
The drive expansion port is an x4 multilane SAS port. Connect a SAS cable
to this port and to a drive storage enclosure.

SAS host ports
The DS3500 SAS host ports are each a x4 multilane, 6 Gbps universal
mini-SAS port. Connect a SAS cable from your host system SAS host bus
adapter to a host port on each controller.
Drive expansion port
The drive expansion port is an x4 multilane SAS port. Connect a SAS cable
to this port and to a drive storage enclosure.

Enclosure ID settings

The enclosure ID is a unique two-digit identifier for each enclosure in the storage
subsystem configuration. In a dual controller or ESM configuration, both enclosure
IDs are identical under normal operating conditions. Each EXP3500 storage storage
enclosure and DS3500 storage subsystem in the storage subsystem configuration
must have a unique storage enclosure ID.
The controller automatically sets the enclosure ID. You can change the setting
through the Storage Manager software, if necessary. The range of supported
enclosure ID settings is 0 through 99. The enclosure ID is normally set to a value of
00 at the factory.
The enclosure ID is displayed on the seven-segment numeric display located on
the back of each controller and ESM.

Working with SAS cables

Each DS3500 storage controller has up to four x4 multilane SAS host ports and a
single x4 multilane SAS port for drive channel connections.
