Joined-bus mode

Up

Low Voltage Differential (LVD) termination on the

 

 

split-bus module is disabled, electrically joining the

 

 

two SCSI buses to form one contiguous bus. In this

 

 

mode, neither the split-bus nor the cluster Light-

 

 

Emitting Diode (LED) indicators on the front of the

 

 

enclosure are illuminated.

Split-bus mode

Center

LVD termination on the split-bus module is enabled

 

 

and the two buses are electrically isolated, resulting in

 

 

two seven-drive SCSI buses. The split-bus LED

 

 

indicator on the front of the enclosure is illuminated

 

 

while the system is in split-busmode.

Cluster mode

Down

LVD termination is disabled and the buses are

 

 

electrically joined. The cluster LED on the front of the

 

 

enclosure is illuminated while the system is in

 

 

cluster mode.

 

 

 

The split-bus module has only one LED indicator (see Figure 3-1 for location), which is illuminated when the module is receiving power.

Enclosure Management Module (EMM)

The EMM serves two primary functions in your storage system:

•SCSI bus expansion — Acts as a buffer for the SCSI bus, electrically dividing the bus into two independent segments while logically allowing all SCSI bus traffic to pass through it transparently. The buffer improves the quality of the SCSI signals and allows longer cable length connections.

•Management functions — Includes SCSI enclosure services (SES) and SCSI accessed fault-tolerant enclosures (SAF-TE) reporting to the host initiator, control of all enclosure LED indicators, and monitoring of all enclosure environmental elements such as temperature sensors, cooling modules, and power supplies.

A system with redundant enclosure management features two EMMs that are designated as primary and secondary and can be configured in either a cluster, joined-bus, or split-bus mode. A nonredundant configuration consists of one EMM and one SCSI terminator card, and can be configured in a joined-bus mode only. In a redundant system, only one EMM per SCSI bus is active at one time, so only one EMM per SCSI bus can respond to SCSI commands from

an initiator.
