4.0 Determining Drive and Sled Designations

The Diamond Storage Array has been designed with 12 sleds, each holding two drives. The easiest way to configure a array is to use all the drives on all the sleds. The firmware uses a numbering system to determine which drives and sleds it is affecting.

We recommend that all sled slots are filled

 

 

logical disk or Logical Unit (LUN). Each LUN is

contiguously, starting with the first slot next to the

broken into logical blocks of 512 bytes each,

numbered 0 through n (the Logical Block Number

When configuring a Diamond Array with fewer

or LBN). A 100 GB LUN has approximately

 

 

than 12 drive sleds, you must consider several

The Diamond Storage Array with firmware

 

 

• Each sled is connected to its own internal ATA

version 3.1 and newer uses a unique numbering

 

bus with two disk drives, numbered 1 and 2.

 

 

• Two green LEDs, labeled Drive 1 and Drive 2,

 

convention to orient its drives and sleds to the

 

 

 

controlling firmware. Older versions do not use

solidly lighted when there is no activity.
