Table 4. Solid-state drive rules for the 5887 disk drive enclosure.
Disk drive enclosure
Mixing rules
5887 disk drive enclosure
(EXP24S SFF Gen2-bay Drawer)
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, PCI Express Gen2 (PCIE2), PCI Express Gen3 (PCIe3)
adapter or a pair of adapters.
v
The EXP24S can also be attached to a pair of internal SAS controllers (FC EJ0U)
in a system with an external SAS port.
v
The mixing of the SSDs and HDDs is as follows:
– SSDs and HDDs cannot be mixed when configured in mode 1.
– SSDs and HDDs can be mixed when configured in mode 2: one disk partition
can be SSDs and the other disk partition can be HDDs, but you cannot mix
within a disk partition.
– SSDs and HDDs can be mixed when configured in mode 4 depending on the
adapter support. Each disk partition can be either SSDs or HDDs, but cannot
mix within a disk partition.
