LDOMS 1.3 CONFIGURATION DEMO ON SOLARIS 10

LDOMS:
A logical domain is a discrete logical grouping with its own  operating  system,  resources,  and identity within a single computer system. Each logical domain can  be  created,  des-troyed,  reconfigured,  and  rebooted independently, without requiring a power cycle of the server.
Control domain
  Creates and manages other logical  domain  and  services  by  communicating  with the hypervisor.
Service domain 
   Provides   services   to   other   logical domains,  such as a virtual network switch   or a virtual disk service.
  I/O domain 
       Has direct ownership of and direct  access to physical I/O devices, such as a network card in a PCI EXPRESS  controller.  Shares  the  devices  to other domains in the form of virtual devices when the I/O domain  is also  a  service domain. The number of I/O domains you can have is dependent on  your platform architecture.
 For example,
if  you  are using a Sun UltraSPARC  T1  processor,  you can have a maximum of two I/O domains, one of which  must  also  be  the  control domain.
Guest domain  
   Uses services from  the  I/O  and  service  domains  and  is  managed  by  the control  domain.
NOTE:
 WE can use the Logical Domains Manager to establish  dependency relationships between domains.
Master domain  
 A domain that has one or more domains  that depend  on  it.
 A master domain specifies a failure policy to be enacted by  its  slave domains  when  the master domain fails.
 depending on the master  domain’s   failure  policy, a slave can be left as-is, panicked, rebooted,  or  stopped  when  the master domain fails.
     Slave domain    
A domain that depends on another domain.  A domain   can  specify  up  to  four  master  domains that indictate the failure policy  to enact  when  one  or  more  of  the  master  Following  are  the  supported

FIRMWARELEVEL: Ok prompt level
OPERATING SYSTEM LEVEL: Solaris,windows,linux,
APPLICATIONS: Oracle ,Sap …...

2.SOLARIS CONTAINERS


3.LOGICAL DOMAINS

• The hypervisor is the layer between the operating system and hardware.
• The hypervisor implements a stable sun4v interface. The operating system makes calls to the hypervisor, and therefore, does not need to know intimate details about the hardware, even if the platform changes.
• The hypervisor is very thin; it exists only to support the operating system for hardware-specific functions, making it small and simple, which assists in stability.
 • The hypervisor creates a virtual machine allowing the system to be partitioned by exposing some of the resources to a specific partition and hiding others.
4.DYNAMIC DOMAINS


NOTE:
Resource Management     :  Hear Task,Project is implimented.
Solais Containers  :           Hear o/s level virtulization
Ldoms    : Hear  Firmware level virtulization
Dynamic Domas  :           Hear  System Control level
