the appropriate personnel, floor layouts, and any ancillary moving equipment that is
required to facilitate delivery.
This section describes about the room environment which must be considered before
DLm installation.
Install the DLm in a properly equipped and well-ventilated computer room.
DLm requires the environmental specifications that are outlined in each chapter for
the specific DLm model. Ensure that the site meets or exceeds the specifications that
are listed for both raised and non-raised floor environments.
This section describes about the requirements for system host cabling.
The Presite Survey, completed with the Dell EMC Systems Engineer, reports the Fibre
connection (FICON) cable length that is required for each host connection to the
DLm. From a physical planning perspective, review the routing paths from the hosts to
the DLm system. Resolve any physical access issues before the installation day.
Layout and space considerations are described in the chapter for the specific DLm
model.
CAUTION When moving the DLm cabinets down an incline, the rear of the cabinet
must go first and when moving up an incline, the rear of the cabinet must go last.
This section describes about the remote support service.
Remote support is an important and part of the Dell EMC customer service and
support strategy. Communication between the Dell EMC Customer Support Center
and the DLm occurs either through IP connections to the local area network.
DLm supports Secure Remote Support (SRS) Gateway that provides a secure, IP-
based, distributed remote service support solution giving you command, control, and
visibility of remote support access.
Contact Dell EMC Customer Support to configure SRS. This is an optional feature.
This section provides an overview of SSH trust establishment.
DLm features such as DLm health monitoring, DDRL, command processors,
configuration, and setup tools must run commands and operations on the backend
storage systems remotely. For this operation to work, SSH trust must be established
between DLm VTEs and the backend storage systems. SSH trust ensures that
applications on the DLm can run commands on the storage system without a
