Enclosure cabling - multiple enclosures
You can connect additional expansion enclosures to an E-842R RAID enclosure. Multiple enclosures
are connected together using SAS patch cables, up to a maximum of five enclosures, including the
RAID enclosure. A typical two-expansion enclosure configuration is shown below. To fully populate
your installation to the maximum number of enclosures, follow the example below connecting the
enclosures in the same fashion for each additional expansion enclosure.
Drive slot arrangement
Each enclosure has 12 drives which are referenced by their locations as shown in the following
table. Drives are numbered column/row. For information on installing drive carrier modules, see
“Installing a drive carrier module” on page 27.
