The following standards are maintained in the sample configurations:
Dual domain
Single domain
Device
Depending on the type of server blade
used, two or four switches are installed in
the c-Class enclosure, providing dual paths
between the server blades and the
switches.
nl
When using full-height or half-height server
blades, two switches are required, installed
in adjacent interconnect bays, for example,
in interconnect bays 5 and 6.
nl
When using double-density server blades
in the c7000 enclosure, four switches are
required, installed in different interconnect
rows, for example, in interconnect bays 5,
6, 7, and 8.
Depending on the type of server blade
used, one or two switches are installed in
the c-Class enclosure, providing a single
path between the server blades and the
switches.
nl
When using full-height or half-height
server blades, one switch is required.
nl
When using double-density server blades
in the c7000 enclosure, two switches are
required, installed in different interconnect
rows, for example, in interconnect bays
5 and 7.
SAS switches:
Two controllers are installed in
MSA2000sa controller enclosures,
providing an alternate path between the
switches and the MSA2000sa.
One controller is installed in MSA2000sa
controller enclosures, providing a single
path between the switch and the
MSA2000sa.
MSA2000sa SAS controller
modules:
Four I/O modules are installed in the
MDS600 storage enclosure, providing
alternate paths between the switches and
the dual-port SAS drives in each MDS600
enclosure drawer.
Two I/O modules are installed in the
MDS600 storage enclosure, providing a
single path between the switch and the
single-port SATA drives in each MDS600
enclosure drawer.
MDS600 SAS I/O modules:
Two cables are connected between the
switch and the storage enclosure: one from
the primary controller or I/O module and
one from the secondary controller or I/O
module. If ports on the switch and the
storage enclosure are available, connect
an additional cable between the devices,
for improved performance.
A single cable is connected between the
switch and the storage enclosure. If ports
on the switch and the storage enclosure
are available, connect an additional cable
between the devices, for improved
performance.
Cabling:
When creating and assigning zone groups to server bays, assign server bays 1–8 to
zone groups associated with storage connected to switch ports 1, 2, 3, or 4. Assign
server bays 9–16 to zone groups associated with storage connected to switch ports
5, 6, 7, or 8. For more information, see
“Zoning requirements and device mappings”
