Sample Topologies

Comparing with previous F16F series, there are six (6) dedicated RCC
(Redundant Controller Communications) channels strung between partner
RAID controllers in F16F-R4031. There are no longer configurable "RCC"
or "Drive + RCC" options. These RCC SATA channels are not user-
configurable.
Fault-tolerant Links
The primary concern for configuring host-side data links is to eliminate
single points of failure. It is therefore recommended that the data links
between application servers and storage are configured as fault-tolerant
pairs, including all devices such as FC switches and HBAs. If a data
path is disconnected, the alternate data path can continue the service.
Up to six (6) Fibre Channel SBODs can be added with CH2 and CH3
connection for capacity expansion. Note that the 16 disk drives within
the F16F chassis take up the first 16 physical loop IDs.
Up to seven (7) SBODs can be added for capacity expansion if CH4
and CH5 are manually configured as drive loops.
With fault-tolerant host links, it is also necessary to implement
management software, such as Infortrend's EonPath™ packages, to
manage the fault-tolerant data links to a RAID volume.
