Table 18: Cabling principles (FC Expansion Bricks)
defines the principles that
must be followed when cabling FC Expansion Bricks in strings within a Pillar
Axiom 600 system.
Table 18 Cabling principles (FC Expansion Bricks)
Cabling principle
Applicability
FC RAID Bricks (version 1) can be configured alone or in pairs of
one FC RAID Brick (version 1) and one FC Expansion Brick
(version 1). FC RAID Bricks (version 2) do not support
FC Expansion Bricks.
ALL
FC Expansion Bricks are connected to FC RAID Bricks (version 1)
using the J0, J1, and PNet ports. One FC Expansion Brick is
supported with one FC RAID Brick (version 1). For more
information, see
Pillar Axiom 600 SSF Cabling Reference.

ALL
Table 19: Cabling principles (Brick order in strings)
defines the order in which
different Bricks are placed in the string within a Pillar Axiom 600 system.
Table 19 Cabling principles (Brick order in strings)
Cabling principle
Applicability
The functionality or performance of Bricks is not affected by their
relative position in a Brick string.
ALL
Factory manufacturing practice places SSD Bricks at the head of
string position followed by FC Bricks, and then SATA Bricks.
NEW
When adding Bricks to an existing system, attach the new Brick to
the last Brick on a string.
Note: The practice of adding Bricks to the last Brick on the string
is recommended for non-disruptive upgrades and for existing
customer systems. The goal in the field must be to perform non-
disruptive upgrades, if at all possible.
FIELD
Table 20: Cabling principles (Brick balance in strings)
defines the balance that
must be maintained between the various Brick types in the Brick strings within a
Pillar Axiom 600 system.
