24 Installing the enclosures
• Qualified HD mini-SAS cable and fan-out cable options supporting SFF-8644 and SFF-8088 host
connection (also see HD mini-SAS host connection on page 33):
• 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.
• A qualified bifurcated SFF-8644 to SFF-8644 fan-out cable option is used for connecting to a 12
Gbit/s enabled host.
NOTE: Using fan-out cables instead of standard cables will double the number of hosts that can
be attached to a single system. Use of fan-out cables will halve the maximum bandwidth available
to each host, but overall bandwidth available to all hosts is unchanged.
• A qualified bifurcated SFF-8644 to SFF-8088 fan-out cable option is used for connecting to a 6
Gbit/s enabled host (see Note above).
See HD mini-SAS host connection on page 33 and SAS fan-out cable option for more information
about bifurcated SAS cables.
TIP: Requirements for cabling S3200/S2200 controller enclosures and supported drive enclosures
are summarized in Table 4 on page 24.
Table 4 on page 24 summarizes key characteristics of controller enclosures and compatible drive
(expansion) enclosures relative to cabling, including: the cable type needed for attaching one specific
enclosure model to another specific enclosure model; internal disk drive speeds; number of disks of
given size (SFF or LFF) supported per enclosure model; and SAS expander data rates. Enclosure form
factor and NEBS compliance information are also provided.
1
These compatible product models feature 6 Gbit/s internal disk and SAS expander link speeds.
2
See CNC technology on page 30 for information about locating and installing qualified SFP options into CNC ports.
3
See 12 Gb mini-SAS ports on page 32 for information about host connection using SFF-8644 high-density mini-SAS connectors.
4
NEBS compliance is a future consideration for S3200/S2200 enclosures.
5
The S3200 and S2200 enclosures support single or dual-IOMs.
