RAID-1 RAID-5 RAID-10 FAST W HS POOL


This page allows you to modify some of the array attributes.

This help is divided into sections :


Additional 'Hot-spare' Attributes:
(Common to RAID-1, 5 & 10)
Top

All array types, except RAID-0, can make use of Hot-spare resources to further enhance the availability of the SSA subsystem.


Hot-spare Pool Additional 'Hot-spare Pool' Attributes:
(IBM Advanced SerialRAID/X Adapter Only)
Top

With the Advanced SerialRAID Adapter, all array types, except RAID 0, can make use of Hot-spare Pool resources. These Pools further enhance the availability of the SSA subsystem.


RAID-0 Icon

Additional 'RAID-0' Attributes:

Top

Note:

RAID-0 arrays do not have any attributes that can be modified.


RAID-1 Icon

Additional 'RAID-1' Attributes:

Top

Note:

RAID-1 arrays can only consist of two components.

The attributes of your RAID-1 arrays will depend on the adapter that created the array. Select your adapter from this list to view the RAID-1 attributes your adapter will present.


RAID-1 Icon

Additional 'RAID-1' Attributes:

when created with the
IBM SSA RAID Adapter or the
IBM SSA RAID Cluster Adapter

RAID-1 Arrays created with either of these adapters will have the following attributes. These are in addition to the Hot-spare attributes outlined above.


RAID-1 Icon

Additional 'RAID-1' Attributes:

when created with the
IBM Advanced SerialRAID/X Adapter

RAID-1 Arrays created with this adapter will have the following attributes. These are in addition to the Hot-spare attributes outlined above. For further information see the help which explains Multiple Domains and Component Ordering.


RAID-5 Icon

Additional 'RAID-5' Attributes:

Top

Note:

RAID-5 arrays can consist of three to sixteen components. The larger the number of components, the worse the performance may be for long transfers. However, the larger the number of components, the greater the reduction in the overhead of the parity function. Therefore the available capacity is maximised by using a larger number of components.

RAID-5 attributes depend on which adapter created the array. Select your adapter from this list to view the relevant attributes.


RAID-5 Icon

Additional 'RAID-5' Attributes:

when created with the
IBM SSA RAID Adapter

RAID-5 Arrays created with this adapter will have the following attributes. These are in addition to the 'Hot-spare' attributes outlined above.


RAID-5 Icon

Additional 'RAID-5' Attributes:

when created with the
IBM SerialRAID Adapter or the
IBM Advanced SerialRAID/X Adapter

RAID-5 Arrays created with either of these adapters will have the following attributes. These are in addition to the 'Hot-spare' attributes outlined above.


RAID-10 Icon

Additional 'RAID-10' Attributes:

when created with the
IBM Advanced SerialRAID/X Adapter

Top

RAID-10 Arrays are only supported by the Advanced SerialRAID/X Adapter. Such arrays have the following attributes in addition to the 'Hot-spare' attributes outlined above. For further information see the help which explains Multiple Domains and Component Ordering.

Note:

RAID-10 arrays can consist of four to sixteen components. The larger the number of components, the more the data is spread across disks and performance is increased. With a finite number of disks available for RAID-10 arrays, best performance is achieved with an equal number of RAID-10 arrays on each SSA loop.


Fast Write Icon

Additional 'Fast Write' Attributes:

when created with the
IBM SerialRAID Adapter or the
IBM Advanced SerialRAID/X Adapter

Top

See the Fast Write Attributes in the array view help.


Actions:

Modify

This action submits the modified attributes.

Note:

Some modifications may cause the array to start rebuilding.

Cancel

This action aborts the array modification, and returns to the relevant Array View.
