A medium-sized insurance company has an IBM System Storage ™ DS8000 production machine and several IBM System p and IBM System i servers. The company wants to add three DS6000 machines, primarily to perform copy service functions, and these new machines must be compatible with the current devices. What is the best logical device configuration for this situation?
Clients such as this insurance company should use the DS Storage Manager tasks
to customize a logical configuration that is compatible with their existing
devices. The administrator's first step is to select which DS6000 system to
configure. The second step is to create an extent pool using the autocreation
method. The administrator specifies that 4 terabytes of storage, a fixed-block
type of storage, and a RAID 5 level are required.
The result is a DS6000 system configured to include two extent pools that are
allocated to 500 volumes each. The administrator would then make a copy of this
configuration for the second machine. The third machine has the same configuration
as well, but is formatted for RAID 10. The logical configuration would include
three DS6000 machines, two formatted as RAID 5 and one formatted as RAID 10,
with 3000 volumes of storage.
