4 Before you begin D6000 overview The D6000 is available in several standard-shipping configurations. For cabling purposes associated with this document, the primary types of configurations include the following: Single-domain ready: One I/O module and one I/O blank are installed in each D6000 storage drawer. To convert a single-domain D6000 to dual-domain, obtain and install an additional 6G D6000 I/O module in each storage drawer. Dual-domain ready: Two I/O modules are installed in each D6000 storage drawer. For information about the available, standard-shipping D6000 configurations, including information about the pre-installed hard drive models, see the D6000 QuickSpecs on the HP website ( For QuickSpecs, technical overviews, and other information for a wide variety of HP products, see the HP Product Bulletin on the HP website ( The Product Bulletin is a central information resource of overviews and specifications for HP hardware and software products. Cabling overview The D6000 is designed to support a variety of host environment deployments, with the SAS cabling from the D6000 being very similar, regardless of host environment. For information about supported servers and controllers, see the D6000 QuickSpecs on the HP website ( Cabling guidelines Observe the following guidelines: The only supported cable is the 2.00 m (6.56 ft) mini-sas cable. (8x wide mini-sas cables are not supported in direct connect environments.) Mini-SAS cables do not ship with the D6000. Hosts must be powered down before connecting SAS cables to the D6000. The D6000 has two storage drawers, with each drawer being an independent unit. A separate connection is needed for each drawer. Cascading I/O modules from D6000 drawers is not supported.

6 Cabling Connecting a D6000 in a single-domain environment to one server This example illustrates cabling for a single-domain environment, with both D6000 storage drawers being accessed by the same server. In this example, one 2-port controller is installed in the server. Note the following: One cable from the D6000 storage drawer to the server provides single-domain connectivity. For dual-domain support, an additional 6G, D6000 I/O module must be installed in the storage drawer and cabled to the same server. The cable is connected to the D6000 primary I/O module, SAS port 1. For consistency across all D6000 deployments, even though SAS port 1 and SAS port 2 are functionally equivalent, HP recommends using only I/O module SAS port 1 in direct-connect environments.

7 Connecting a D6000 in a dual-domain environment to two servers This example illustrates cabling in a dual-domain environment, with each D6000 storage drawer being accessed by a different server. In this example, one 2-port controller is installed in each server. Note the following: Two cables from the D6000 storage drawer to the server provide dual-domain connectivity: o One cable connects to the D6000 primary I/O module, SAS port 1. o One cable connects to the D6000 secondary I/O module, SAS port 1. o For consistency across all D6000 deployments, even though SAS port 1 and SAS port 2 are functionally equivalent, HP recommends using only I/O module SAS port 1 in direct-connect environments. Cables from each D6000 storage drawer are connected to two different servers. Cabling 7

8 Connecting a D6000 in a dual domain environment to one server This example illustrates cabling in a dual-domain environment, with both D6000 storage drawers being accessed by the same server. In this example, a 4-port controller is installed in the server. Note the following: Two cables from the D6000 storage drawer to the server provide dual-domain connectivity: o One cable connects to the D6000 primary I/O module, SAS port 1. o One cable connects to the D6000 secondary I/O module, SAS port 1. o For consistency across all D6000 deployments, even though SAS port 1 and SAS port 2 are functionally equivalent, HP recommends using only I/O module SAS port 1 in direct-connect environments. Cables from the two D6000 storage drawers are connected to the same server. Cabling 8
