Cabling the Lx0 RAID chassis
Level 35 K2 SAN
If you have more Expansion chassis than those illustrated, continue the indicated
cabling pattern, alternating connections for additional Expansion chassis between
DP1 and DP0. Expansion chassis 1, 3, 5, 7, etc. (odd numbers) connect to DP1.
Expansion chassis 2, 4, 6, 8, etc. (even numbers) connect to DP0. For example, if you
have four Expansion chassis (an even number), they are evenly balanced, so you have
two connected to DP1 and two connected to DP0. If you have five Expansion chassis
(an odd number), the “plus one” Expansion chassis is always connected to DP1, so
you have three connected to DP1 and two connected to DP0.
