Mixing rules
v SSD and HDD cannot be mixed on
a pair of 5903 adapters.
v A maximum of 9 SSDs are
supported on a pair of 5903
adapters.
v SSDs and HDDs can be mixed in
this drive enclosure.
v A maximum of 24 drives are
supported in this enclosure.
v SSDs and HDDs can be attached to
the SAS Controller PCI or PCI-X
adapters. Also, can be attached to
the embedded SAS controller in a
system with an embedded SAS
port.
v A maximum of 24 drives are
supported in this enclosure.
v The EXP24S can be configured as
one set of 24 bays (mode 1), two
sets of 12 bays (mode 2), or four
sets of 6 bays (mode 4).
v The EXP24S serial-attached SCSI
(SAS) ports are attached to SAS
controllers, which can be a SAS
Peripheral Component
Interconnect-X (PCI-X) adapter, PCI
Express (PCIe) adapter, or a pair of
adapters. The EXP24S can also be
attached to an embedded SAS
controller in a system with an
embedded SAS port.
v The mixing of the SSDs and HDDs
is as follows:
– SSDs and HDDs cannot be
mixed in a logical group when
configured as in mode 1.
– SSDs and HDDs can be mixed
when configured as in mode 2:
one set can be SSDs and the
other set can be HDDs.
– SSDs and HDDs cannot be
mixed when configured as in
mode 4 because the SSDs are
not supported by the adapter
that is required to configure the
5887 for mode 4.
