Cabling Guidelines; Single Domain Cabling Diagrams With D6000 Disk Enclosures - HP StoreEasy 1000 Storage Administrator's Manual

Cabling guidelines

When connecting disk enclosures to the StoreEasy system, consider the following guidelines:
In a single domain configuration, the secondary I/O modules on the D6000 are not used, so
they may or may not be installed. The cabling diagrams in this section show the secondary
I/O modules installed.
For single domain configurations, the maximum number of disk enclosures supported by
controller model are:
◦
P222: 4 D2000s (up to 104 drives total)
◦
P421: 1 D6000; 4 D2000s (up to 104 drives total)
◦
P822: 8 D2000s (up to 227 drives total); 2 D6000s
For dual domain configurations, the maximum number of disk enclosures supported by controller
model are:
◦
P222: No support for dual domain
◦
P421: 1 D6000 (1/2 utilized)
◦
P822: 1 D6000; 8 D2000s (up to 227 drives total)
NOTE:
system could have additional or alternate controllers installed, which would affect the overall
number of supported disk enclosures. The maximum number of enclosures that can be connected
to a controller is eight.
In the cabling diagrams for the D2000 disk enclosure, the D2600 Disk Enclosure is used. Be
aware that the cabling is exactly the same for the D2700 Disk Enclosure.
The D6000 does not support the use of SAS daisy chains; the D2000 does support SAS daisy
chains. In a SAS daisy chain, the D2000 disk enclosures are connected to each other – I/O
module A from each disk enclosure is connected together and I/O module B of each disk
enclosure is connected together.
Only supported, documented cabling configurations are shown. Only cabling configurations
shown in this document or in related D2000 or D6000 documentation are supported
configurations.
CAUTION:
controllers in the StoreEasy system to the same disk enclosure; this is an unsupported configuration
and might result in data loss. If the StoreEasy system is configured incorrectly, and you attempt to
use Pool Manager, Pool Manager will detect the configuration and display an error message. The
controllers can be connected to different disk enclosures.
