Predefined configurations
Several predefined configurations are available to help in configuring the zoning
for the SAS connectivity module.
Predefined configurations are available to support most typical environments.
There are several ways to choose a predefined configuration, including:
v
Storage Configuration Manager
v Advanced management module configuration wizard
v
Advanced management module Web based user interface
v
The SAS connectivity module command-line interface (CLI)
Note:
Predefined configuration 01 is not intended to be used with the BladeCenter
S system.
Predefined configurations cannot be modified. Therefore, when choosing a
predefined configuration, plan for future growth. For example, if you are currently
going to install a single blade server, but you intend to install additional blade
servers in the future, you might consider choosing the predefined configuration
that supports the total number of blade servers that will be installed. Then, when
you do install additional blade servers, you will not need to modify the predefined
configuration.
If you implement a predefined configuration that meets your current requirements
and then change the BladeCenter S system (such as adding an additional blade
server), you will need to choose a new predefined configuration that matches the
BladeCenter S system setup.
Tip: You can use Storage Configuration Manager to edit a predefined
configuration. However, you must save any changes that you make as one of the
four user-defined configurations.
Predefined storage configuration 02
Use predefined storage configuration 02 to implement up to six blade servers, two
SAS connectivity modules, and up to two storage modules, each with up to six
hard disk drives. Each blade server can access one hard disk drive in each storage
module and all external ports on both SAS connectivity modules.
This configuration has the following characteristics:
v
Each blade server has access to a single hard disk drive in each storage module
(for a maximum of two hard disk drives if you are implementing both storage
modules).
With this predefined configuration, blade server bays are mapped to hard disk
drive locations in each storage module. The location of the hard disk drives in
each storage module is important. For example, if you install a blade server in
blade server bay 3, it can access only the hard drives located in hard drive bay 3
of each storage module.
v
The SAS connectivity module in I/O module bay 3 controls access to the hard
disk drives in storage module 1.
v
The SAS connectivity module in I/O module bay 4 controls access to the hard
disk drives in storage module 2.
v
All blade servers have access to all external ports on both SAS connectivity
modules.
