2 Disk shelves can
include 24x HDD,
or combine 20x
HDD plus 4x
write-optimized
flash accelerators
(SSDs). Total
number of chains
is four. Any
combination of
disk-only and
write-optimized
shelves can be
combined within
the chain in any
order. You can
also connect
mixed disk shelf
types (Oracle

the same
controllers, but
each chain must
contain only the
same disk shelf
type. Directly
connecting
different disk
shelf types is not
supported.
