Chapter 3: System Connections

 

 

                                                                                                                   3-5

 

With more disk drives over the SAS expansion links, you can create 
more logical groups of drives. Avail these logical partitions  using 
more LUN numbers.  

 

 

 

Sample 2:

  DAS (Direct-Attached  Storage)  Connections to Two 

Servers 

 NOTE: 

If  you would like a LUN (a logical partition) to be accessed by multiple hosts, file 
locking or multi-pathing access control will be necessary. 

 

Single Paths to Servers
