Introduction 1 CAUTION: See the Safety, Environmental, and Regulatory Information document for important safety information before following any procedures listed in this document.

Cabling the storage enclosure There are a number of methods to cable the Dell Storage MD1280 series storage enclosure to host servers and to additional Dell Storage MD1280 series storage enclosures. The particular configuration selected depends on storage capacity, level of resiliency of both the server and storage enclosure, and the OS being used. NOTE: The maximum supported SAS cable length is 4 m. NOTE: Only two systems can be daisy chained behind one HBA or RAID card.

Linux There are three types of configurations supported for Linux host servers: • Single Path configuration: This uses a simplified cabling scheme, but does not provide redundancy or fault-tolerance. Use this when the OS or a higher-level application is being used for data resiliency. • Symmetric Multipath configuration: This uses a cascading configuration that provides path redundancy, but does not provide against enclosure loss.
