EonStor F16F-R/S4031 Installation and Hardware Reference Manual
Single-controller RAID to Dual-controller SBODs
A single RAID controller configuration can still enjoy the path redundancy
by the dual-controller SBODs. The configuration below uses CH2, CH3,
CH4, and CH5 for making two separate dual-loops to expansion enclosures.
When configured as drive loops, the onboard hub with CH4 and CH5 should
be enabled.
This configuration allows capacity expansion to terabytes of disk space and
uses an in-band SES monitoring method that requires no additional
management links. The maximum number of SBODs is limited to the
available loop IDs, 224 IDs on two dual-loops across 4 drive channels.
