Ibm Totalstorage Management Console; Host Systems That The Storage Unit Supports - IBM TotalStorage DS8000 User Manual

IBM TotalStorage Management Console

The IBM TotalStorage Management Console is the focal point for configuration,
copy services management, and maintenance activities.
The Management Console is a dedicated workstation that is physically located
(installed) inside your DS8100 and DS8300 and can automatically monitor the state
of your system, notifying you and IBM when service is required. The Management
Console can also be connected to your network to enable centralized management
of your system using the IBM TotalStorage DS Command-Line Interface or the
storage management software that uses the IBM TotalStorage DS Open API.
To provide continuous availability of customer access to the management console
functions, having a second management console is recommended. This second
management console can be provided in two ways:
v External (outside the 2107) - This console is generally installed in the
v Internal (a second management console that resides within a second 2107) -

Host systems that the storage unit supports

The DS8000 storage unit provides a variety of host attachments so that you can
consolidate storage capacity and workloads for open-systems hosts, S/390 hosts,
and eServer
The DS8100 Model 921 supports a maximum of 16 host adapters and 4 device
adapter pairs, and the DS8300 Models 922 and 9A2 supports a maximum of 32
host adapters and 8 device adapter pairs.
You can configure the storage unit for any of the following system adapter types
and protocols:
v Fibre-channel adapters, for support of fibre-channel protocol (FCP) and fibre
v Enterprise Systems Connection Architecture
For fibre-channel attachments, you can establish zones. The zones must contain a
single port that is attached to a system adapter with the desired number of ports
that are attached to the storage unit. By establishing zones, you reduce the
possibility of interactions between system adapters in switched configurations. You
can establish the zones by using either of two zoning methods:
v Port number
v Worldwide port name (WWPN)
You can configure switch ports that are attached to the storage unit in more than
one zone. This enables multiple system adapters to share access to the storage
series system. Load balancing can help reduce or eliminate I/O bottlenecks
that occur when many I/O operations are directed to common devices that
are using the same I/O path. The SDD also helps eliminate a potential
single point of failure by automatically rerouting I/O operations when a path
failure occurs, thereby supporting enhanced data availability capability.
customer-provided rack. It uses the same hardware as the internal management
console.
This console can be cabled together with the primary internal management
console of the first 2107.'
