Figure 1-1 SES Overview
LUN addressing within the Fabric can be non-sequential because it is based on the switch’s
Domain_ID. Table 1-1 shows the sample LUN mapping used with Figure 1-1.
Figure 1-1 shows that the switch in the lower left hand corner is assigned both LUN5 and
LUN0. (LUN5 because the switch’s
Domain_ID is 5 and LUN0 because the client is
physically connected to that switch.) LUN values for the first byte, shown in Table 1-1, are:
•
00000000 00000000 - the bold characters indicate the local switch
•
0X0X0000 00000000 - the bold characters indicate the SCSI LUN address of the other
switches in the Fabric
