b. Decide whether an external management console is to be installed for the
storage unit. Adding an external management console helps to ensure that
you maintain a highly available environment.
4.
For each base and expansion model, determine the disk storage features that
you need.
a. Select the disk drive set feature codes and determine the amount of each
feature code that you must order for each model.
b. Select the disk enclosure feature codes and determine the amount that you
must order to enclose the disk drive sets that you are ordering.
c. Select the disk cable feature codes and determine the amount that you need
of each.
5. Determine the I/O adapter features that you need for your storage unit.
a.
Select the device and host adapters feature codes to order and choose a
model to contain the adapters. Remember that all base models can contain
adapters, but only the first attached expansion model can contain adapters.
b. For each model chosen to contain adapters, determine the number of each
I/O enclosure feature codes that you must order.
c. Select the cables that you require to support the adapters.
6. Based on the disk storage and adapters that the base model and expansion
models support, determine the appropriate processor memory feature code that
is needed by each base model.
7. Decide which power features that you must order to support each model.
8.
Review the other optional features and determine which feature codes to order.
Management console features
Management consoles are required features for your storage unit configuration.
Customize your management consoles by specifying the following different
features:
v
An external management console as well as the required internal management
console
v Management console external line cords
Internal and external management consoles
The management console is the focal point for configuration, Copy Services
functions, remote support, and maintenance of DS8000 storage units.
The hardware management console (HMC) is a dedicated appliance that is
physically located inside your storage unit and it can proactively monitor the state
of your system, notifying you and IBM when service is required. It also can be
connected to your network for centralized management of your system using the
IBM System Storage DS Command Line Interface (CLI) or storage management
software through the IBM System Storage DS Open API. (The DS Storage Manager
cannot be launched from the HMC.)
You can also use the DS CLI to control the access of your service and support
personnel to the HMC remotely.
