PRIMERGY S40-DF capacity
extension
The PRIMERGY S40-DF is the active component in the PRIMERGY S40 family
of storage subsystems. The integrated disk array controller allows you to extend
storage capacity using additional externally-connected passive PRIMERGY
S40-ES storage devices. Two of these so-called “daisy-chain” configurations,
i.e., with one or three PRIMERGY S40-ES units, are supported (see also the
chapter on “Configurations” in the PRIMERGY S40-DF Operating Manual).
In order to use a configuration with three external PRIMERGY S40-ES units,
you will need the 1-channel version of the PRIMERGY S40-DF.
This manual contains conversion instructions which describe the steps required
to prepare a PRIMERGY S40-DF (3-channel version) for capacity expansion
with three PRIMERGY S40-ES subsystems.
For more assistance in understanding the details here, see also the operating
instructions for the “PRIMERGY S40-DF Storage Subsystem”. Further relevant
information can be found in the manual “Safety, Warranty and Ergonomy“ (see
section “Related publications” on page 21).
