22 QXS 12G Site Planning Guide
Tab l e 10 provides the QXS-324/424 12G chassis components/CRUs.
CAUTION: The RAID chassis supports dual-controller configuration only.
- If a partner controller fails, the storage system will fail over and run on a single controller module
until the redundancy is restored.
- A RAID controller or expansion IOM must be installed in IOM slot to ensure sufficient air flow
through the chassis during operation.
