Ibm Midrange System Storage Expansion Enclosure - IBM Midrange System DS4000 Series Hardware Manual

1.3 IBM Midrange System Storage expansion enclosure

At the time of writing, the IBM Midrange System Storage expansion enclosures offer a 4 Gbps
FC interface, and four models are available:
EXP810 Expansion Enclosure
This expansion unit is packaged in a 3U rack-mountable enclosure, supports up to 16 FC
disk drives or E-DMM SATA drives. It contains 16 drive bays, dual-switched 4 Gbps ESMs,
and dual power supplies and cooling components. Fully populated with 450 GB FC disk
drive modules, this enclosure offers up to 7.2 TB of raw storage capacity or up to 16 TB
when populated with the 1000 GB E-DDM SATA drives. The EXP810 expansion unit is the
only one that may be connected to every storage subsystem of the DS4000/DS5000
family. Through the proper firmware level, this expansion unit is able to host both FC and
SATA Drives. Intermix of FC and SATA drives is supported within this expansion enclosure.
EXP5000 Expansion Enclosure
This expansion unit is packaged in a 3U rack-mountable enclosure, supports up to 16 FC
disk drives, E-DMM SATA drives, Full Disk Encryption (FDE) drives, and up to 20 SSD. It
contains 16 drive bays, dual-switched 4 Gbps ESMs, and dual power supplies and cooling
components. Fully populated with 600 GB FC disk drive modules, this enclosure offers up
to 9.6 TB of raw storage capacity or up to 16 TB when populated with the 1000 GB E-DDM
SATA drives. The EXP5000 expansion unit may be connected to the DS5100 or DS5300
storage server. Through the proper firmware level, this expansion unit is able to host both
FDE, FC, SATA drives, and SSD as well. An intermix of FC, SATA, FDE, and SSD drives is
supported within this expansion enclosure.
EXP520 Expansion Enclosure
This expansion unit is packaged in a 3U rack-mountable enclosure, supports up to 16 FC
disk drives, E-DMM SATA drives, or Full Disk Encryption (FDE) drives. It contains 16 drive
bays, dual-switched 4 Gbps ESMs, and dual power supplies and cooling components.
Fully populated with 600 GB FC disk drive modules, this enclosure offers up to 9.6 TB of
raw storage capacity or up to 16 TB when populated with the 1000 GB E-DDM SATA
drives. The EXP520 expansion unit may be connected to the DS5020 storage server.
Through the proper firmware level, this expansion unit is able to host both FDE, FC, and
SATA drives. An intermix of FC, SATA, and FDE drives is supported within this expansion
enclosure.
EXP5060 Expansion Enclosure
The IBM System Storage EXP5060 storage expansion enclosure provides high-capacity
SATA disk storage for the DS5100 and DS5300 storage subsystems. The storage
expansion enclosure provides continuous, reliable service, using hot-swap technology for
easy replacement without shutting down the system and supports redundant, dual-loop
configurations. External cables and Small Form-Factor Pluggable (SFP) modules connect
the DS5100 or DS5300 storage subsystem to the EXP5060 storage expansion enclosure.
The EXP5060 uses redundant 4 Gbps Fibre Channel connections to make connections to
the DS5100 or DS5300 storage subsystem, and another EXP5060 storage expansion
enclosure in a cascading cabling configuration, offering reliability and performance.
Note: A maximum of eight EXP5060 storage expansion enclosures (with 480 hard
drives) can be attached only to the DS5100 and DS5300 storage subsystems and only
SATA disks are supported in the EXP5060 expansion.
