DS8000 performance features
The DS8000 series is designed to provide you with high-performance, connectivity,
and reliability allowing your workload to be easily consolidated into a single storage
subsystem.
The following list provides an overview of some of the features that are associated
with the DS8000 series:
POWER5 processor technology
The DS8000 features IBM POWER5 server technology. Depending on
workload, the maximum host I/O operations per second of the DS8100
Model 921 is up to three times the maximum operations per second of the
ESS Model 800. The maximum host I/O operations per second of the
DS8300 Model 922 or 9A2 is up to six times the maximum of the ESS
model 800.
Industry standard fibre channel disk drives
The DS8000 series offers a selection of fibre channel disk drives, including
300 GB drives, allowing a DS8100 to scale up to 115.2 TB of capacity and
a DS8300 to scale up to 192 TB of capacity.
Four-port fibre channel/FICON adapters
These new adapters not only enhance connectivity, but increase
configuration flexibility because the individual ports can be configured to
support fibre channel or FICON.
HOST attachments
The DS8100 offers up to 16 host adapters (64 FCP/FICON ports) and the
DS8300 offers up to 32 host adapters (128 FCP/FICON ports), further
increasing your ability to share your disk storage.
IBM Standby Capacity on Demand
The IBM Standby Capacity on Demand (Standby CoD) offering allows the
installation of inactive disk drives that can be easily activated as business
needs require. With this offering, up to four Standby CoD disk drive sets (64
disk drives) can be factory or field installed into your system. To activate,
you logically configure the disk drives for use—a non-disruptive activity that
does not require intervention from IBM. Upon activation of any portion of
the Standby CoD disk drive set, you must place an order with IBM to initiate
billing for the activated set. At that time, you can also order replacement
Standby CoD disk drive sets.
Online Information Center
The online Information Center is an information database that provides you
the opportunity to quickly familiarize yourself with the major aspects of the
DS8000 and to easily recognize the topics for which you might require more
information. It provides information regarding user assistance for tasks,
concepts, reference, user scenarios, tutorials, and other types of user
information. Because the information is all in one place rather than across
multiple publications, you can access the information that you need more
efficiently and effectively.
Interfaces of the DS8000
The DS8000 provides management interfaces that contain management tools and
utilities to help you increase productivity.
