Data Manager and One SATA Controller Enclosure

10
Depending on the system ordered, your SGI NAS solution has a 2U compute/data manager, a
RAID controller/drive enclosure (housing one or two RAID controllers), and optional drive
expansion enclosures.
Systems with dual-RAID controllers and serial attached SCSI (SAS) drives come pre-mounted in
a rack from SGI and in most cases only require booting and configuration of the NAS management
software (see "Software Configuration" on page 5). You may need to refer to the rack installation
manual accompanying your system for guidelines on unpacking, moving, and placing a rack.
The written steps and illustrations in "Cabling Examples" on page 10 describe the positioning and
cabling of a single-RAID controller SGI InfiniteStorage NEXIS 2000 system with serial ATA
(SATA) drives. This configuration can be ordered with no rack and would need to be cabled at the
operation site.
Important: Enclosures within a rack should always be placed in locations that keep the RAID
enclosure and any expansion drive enclosures distributed below the data manager. In all cases it
is safest to keep the majority of the weight in the bottom half of the rack.
To cable the single-controller SATA RAID enclosure into an appropriate loop, use the
descriptions and illustrations in the following subsections.
Use the following steps and Figure 1-11 to cable a data manager to a single-controller SATA
RAID enclosure.
1. Connect the Data Manager's Fibre Channel PCI card port A to the RAID controller's host 1
port in the controller enclosure, see Figure 1-11.
2. Connect the Data Manager's Fibre Channel PCI card port B to the RAID controller's host 2
port.
