Planning For Network And Communications Requirements - IBM DS8800 Introduction And Planning Manual

Rack specifications for the external management consoles
If you install your external management console in a non-IBM rack, ensure that the
rack satisfies the required specifications. The following specifications are required
for a non-IBM rack:
v The rack must meet EIA-310-D standards for mounting flanges and hole
locations.
v The front-to-rear distance of the mounting flanges must be 720 mm (28.3 in.).
v The thickness of the mounting flanges must be between 1.9 and 3.3 mm (0.08
and 1.3 in.).
v The mounting flanges must have either 7.1 mm (0.28 in.) diameter holes or 9.6
mm (0.38 in.) square holes on the standard EIA hole spacing.
v The rack must have a minimum depth of 70 mm (2.76 in.) between the front
mounting flange and inside of the front door for appropriate cooling.
v The rack must have a minimum depth of 157 mm (6.2 in.) between the rear
mounting flange and inside of the rear door to install the external management
console and provide cable management space.
v The minimum side-to-side clearance in the rack between the front and rear
mounting flanges must be of 467 mm (18.2 in.) to accommodate the width of the
server and the slide mounting brackets.
v The front edge of the keyboard/display tray is 19 in. wide including the tabs for
the front thumbscrews. To use the tray, it must be extended out fully on its rails.
If the rack is equipped with front covers, ensure that they are hinged in such a
way that in their fully open position they allow the keyboard/display tray to be
fully extended.
v The rack must include perforated front and rear doors and must not prevent the
flow of cool air into or out of the rack.
v The weight-handling capacity of the rack must be able to support the maximum
rack configuration, including all servers, external cables, PDUs, and so on.
v The rack must provide proper stabilization so that the rack does not become
unstable when the external management console or other equipment are pulled
out for use or for service.

Planning for network and communications requirements

You must locate your DS8000 storage units in a location that meets the network
and communications requirements.
Keep in mind the following network and communications issues when you plan
the location and interoperability of your storage units:
v Management console network requirements
v Remote power control requirements
v Host attachment requirements
v SAN considerations
Management console network requirements
You must plan for the network requirements of the management console.
Each management console requires a dedicated connection to the network.
Note: If you plan on accessing the CLI or the Storage Manager and have a firewall
between the management console and your network, you need to open the
following TCP/IP ports prior to installation: 427, 1718, 1720, 1722, 1750,
1755, 6989, and 8451-8455.
