Guidelines
Disk shelves can
include 24x HDD,
or combine 20x
HDD plus 4x
write-optimized
flash accelerators
(SSDs). Total
number of chains
is six with 2X4
port SAS-2
HBAs, and 12
with 4X4 port
SAS-2 HBAs.
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
Storage Drive
Enclosure DE2
and legacy Sun
Disk Shelves) to
the same
controllers, but
each chain must
contain only the
same disk shelf
type. Directly
connecting
different disk
shelf types is not
supported.
