Connecting Data Hosts to the 2510 Array |
This chapter describes cabling data hosts to the Sun StorageTek 2510 Array using iSCSI. It contains the following sections:
The Sun StorageTek 2510 Array is an Internet Small Computer System Interface (iSCSI) system that communicates with hosts over an Ethernet data path.
The hosts that initiate data need a NIC as noted in iSCSI Concepts.
For initial iSCSI configuration information, go to Appendix C.
As shown in FIGURE 4-1, each 2510 controller has two Ethernet host ports for data path transmission with the hosts.
FIGURE 4-1 Ethernet Host Ports on the Controllers
The most common topologies to connect from the host to the controllers are:
Alternate topologies such as single-controller configurations and mixed configurations are described in Appendix D.
FIGURE 4-2 Direct Topology - Two Hosts Connected to Each Controller
1. Insert one end of the Ethernet cable into a host port on the controller.
2. If direct topology, insert the other end of the Ethernet cable into the port on the NIC on the data host.
3. If network topology, insert the other end of the Ethernet cable into a switch port.
a. Connect a second cable from the switch to the port on the NIC.
4. Repeat steps 1 to 3 for each host-to-controller connection.
Use the following guidelines when relocating trays or drives from one storage array to another.
Do not move controller trays or drive expansion trays that are part of a volume group configuration. If you must move array components, contact a Customer Support representative for procedures. A Customer Support representative might direct you to complete several tasks prior to undertaking the relocation. These tasks might include:
After You Connect The Management And Data Hosts, You Can Power On The Trays, As Described In Chapter 7.
