40 Installing the enclosures
Connecting the 4004 Series controller to the 2U48 drive enclosure
The high capacity J6G48 48-drive enclosure, supporting 6 Gb internal disk drive and expander link
speeds, can be attached to a 4004 Series controller enclosure using supported mini-SAS to mini-SAS
cables of 0.5 m (1.64') to 2 m (6.56') length (see Figure 34 on page 42).
Connecting the 4004 Series controller to the 4U56 drive enclosure
The high capacity J6G56 56-drive enclosure, supporting 6 Gb internal disk drive and expander link
speeds, can be attached to a 4004 Series controller enclosure using supported mini-SAS to mini-SAS
cables of 1 m (3.28') to 2 m (6.56') length (see Figure 34 on page 42).
Connecting the 4004 Series controller to mixed model drive enclosures
The 4004 Series controllers support cabling of 6 Gb SAS link-rate SFF and LFF expansion modules—in
mixed model fashion—as shown in examples that follow. The simplified rear-panel views of the J6G48,
J6G24, and J6G12 are identical. The rear-panel view of the J6G56 is unique.
Cable requirements for storage enclosures
The 4004 Series enclosures support 6-Gbps or 3-Gbps expansion port data rates. Use only AssuredSAN
or OEM-qualified cables, and observe the following guidelines (see Table 5 on page 41):
• When installing SAS cables to expansion modules, use only supported mini-SAS x4 cables with
SFF-8088 connectors supporting your 6 Gb application.
• Qualified mini-SAS to mini-SAS 0.5 m (1.64') cables are used to connect cascaded enclosures in the
rack. The “mini-SAS to mini-SAS” cable designator connotes SFF-8088 to SFF-8088 connectors.
• The maximum expansion cable length allowed in any configuration is 2 m (6.56').
• Cables required, if not included, must be separately purchased.
• When adding more than two drive enclosures, you may need to purchase additional 1 m or 2 m
cables, depending upon number of enclosures and cabling method used:
• Spanning 3, 4, or 5 drive enclosures requires 1 m (3.28') cables.
• Spanning 6 or 7 drive enclosures requires 2 m (6.56') cables.
• You may need to order additional or longer cables when reverse-cabling a fault-tolerant configuration
(see Figure 39 on page 45).
• Use only AssuredSAN or OEM-qualified cables for host connection:
• Qualified Fibre Channel SFP and cable options
• Qualified 10GbE iSCSI SFP and cable options
• Qualified 1 Gb RJ-45 SFP and cable options
• Qualified HD mini-SAS standard cable options supporting SFF-8644 and SFF-8088 host connection
(also see HD mini-SAS host connection on page 60):
• A qualified SFF-8466 to SFF-8466 cable option is used for connecting to a 12 Gbit/s enabled
host.
• A qualified SFF-8644 to SFF-8088 cable option is used for connecting to a 6 Gbit/s enabled
host.
NOTE: The 4U56 enclosure does not use the 0.5 m (1.64') length supported for 2U enclosures.
TIP: Requirements for cabling 4004 Series controller enclosures and supported drive enclosures
are summarized in Table 5 on page 41.
Table 5 on page 41 summarizes key characteristics of controller enclosures and compatible drive
(expansion) enclosures relative to cabling concerns.
