The machine types for the DS8000 series specify the service warranty period. The warranty is used for
service entitlement checking when notications for service are called home. All DS8000 series models
report 2107 as the machine type to attached host systems.
Hardware
The architecture of the IBM DS8000 series is based on three major elements that provide function
specialization and three tiers of processing power.
Figure 1 on page 4 illustrates the following elements:
• Host adapters manage external I/O interfaces that use Fibre Channel protocols for host-system
attachment and for replicating data between storage systems.
• Flash RAID adapters manage the internal storage devices. They also manage the SAS paths to drives,
RAID protection, and drive sparing.
• A pair of high-performance redundant active-active Power servers is functionally positioned between
the adapters and a key feature of the architecture.
The internal Power servers support the bulk of the processing to be done in the storage system. Each
Power server has multiple processor cores. The cores are managed as a symmetric multiprocessing
(SMP) pool of shared processing power to process the work that is done on the Power server. Each
Power server runs an AIX
®
kernel that manages the processors, manages processor memory as a data
cache, and more. For more information, see IBM DS8000 Architecture and Implementation on the IBM
Redbooks (www.redbooks.ibm.com/)
