Order number for disk node DN4x
D:GPDS2-DN413 Disk Subsystem
Disk Subsystem for single node configuration
2 SCSI strings with 7 HDD bays each for disks with SCSI U320 LVD I/F
2 SCSI connection module single port U320
rack-mountable box, needs 3U in a 19“-rack
1 cable carrier (ZB527) and 1 support bracket (ZB5211) for 19“-rack
BG5x are included
D:GPDS2-SV30 Power supply unit
Power supply unit, providing redundant PSU configuration for
D:GPDS2-DN413.
The redundant PSU adds dual AC power input/feed to GPDS2- DN413
NOTES on electrical connection and installation of the box
The " Disk Node " (DN413) can be installed in the 19-inch rack PRIMECENTER.
The plug (IEC320) of the AC power cord, which is shipped with GPDS2-DN413, matches with the outlets of the multiple
socket outlets in the 19" rack.
The GPDS2-DN413 has two AC power cords if a redundant PSU is installed. Note that the boxes do support dual AC power
input/feed when a redundant PSU is installed.
To support dual AC power input/feed the AC power cords (of standard PSU and redundant PSU) must be plugged into
independent power grids (circuits) within the building's wiring.
When connecting the cables from standard PSU and redundant PSU to the same power grid (circuit) within the building's
wiring, you will get redundant power supply functionality instead of dual AC power supply functionality.
As long as standard PSU and redundant PSU are working accurately, they share the output load. The outputs of all PSUs
are connected in parallel.
NOTES on ordering
The (basic) disk node for 19" rack (GPDS2- DN413) does NOT include HDDs. HDDs must be ordered as separate items.
To configure DN413 with redundant power supply or support dual AC power input/feed, a redundant PSU (GPDS2-SV30)
must be ordered.
The maximum Disks are 7 per SCSI string and 14 per Disk Node Box GPDS2-DN413.
Standard cable carrier and support brackets for 19” racks PCR2 (BG5x)
All basic boxes for DN413 include support brackets.
1 cable carrier (ZB527) for mounting within 19“ rack BG5x belongs to all DN413
The diagnostic is done via SCSI in band SAF-TE (SCSI Access Fault-Tolerant Enclosure).
Daisy chaining of disk nodes/ packages DN413) or daisy chaining of the 2 strings of one disk node is not supported.
The disk node DN413 comes without SCSI cable. 1 SCSI cable has to be ordered for each connection from a SCSI string (=7
HDD bays) to a SCSI controller within a node as separate items. Order numbers see below chapter drawing.
You may connect the 2 strings of a disk node DN413 to different compute nodes. The DN413 is switched ON/OFF by
"terminator power“ from the SCSI controller, i.e. ON with ON of the first compute node and OFF with OFF of the last compute
node. If the temperature inside the DN413 reaches an abnormal level (because of a fatale error), all connected compute
nodes shut down and switch off the disk node.
