Installing
a
SAS
drive
The
blade
server
has
two
connectors
on
the
system
board
for
installing
optional
small
form
factor
(SFF)
SAS
hard
disk
drives
or
pin-compatible
solid-state
flash
drives.
Depending
on
the
blade
server
model,
a
SAS
hard
disk
drive
or
solid-state
drive
might
already
be
installed.
Two
SAS
drives
can
be
used
to
implement
and
manage
a
redundant
array
of
independent
disks
(RAID)
level-1
array.
See
“Configuring
a
SAS
RAID
array”
on
page
60
for
information
about
SAS
RAID
configuration.
