Connecting Data Hosts |
This chapter explains how to cable data hosts to the system and how to install the host software for data and management host stations. It contains the following sections:
The method you use to connect data hosts depends on how you plan to use the system. The Sun StorEdge 6920 system supports both storage area network (SAN) and direct attached storage (DAS) configurations for host-side server connections.
The main factors in choosing between a SAN or DAS configuration are the number of host bus adapter ports required, the number of Sun StorEdge 6920 system ports required, and the bandwidth required. All host bus adapters and software supported in the SAN are also supported in DAS configurations. You need to first understand the requirements of your application to determine which method to use. For information about DAS and SAN configurations, see the Best Practices for the Sun StorEdge 6920 System for guidelines.
Redundant Fibre Channel (FC) ports located on the service panel are available for data host or external storage connections. FC ports in rows A and paired with FC ports in row C, and FC ports in rows B are paired with FC ports in row D.
To determine which ports are active on your system, open the service panel and check the cards installed in the DSP chassis. DSP slots 1, 2, 3, and 4 correspond to rows A, B, C, and D (respectively) on the service panel.
Your system can have one of the configurations listed in TABLE 4-1.
|
Row / Ports Available for Data Host/ External Storage Connections |
|||
|---|---|---|---|
|
16 SC[1] FC |
|||
FC Port connections are typically evenly allocated between SAN/server and internal storage. However, you can allocate additional ports for either host or internal storage connections, depending on the needs at your site. If you need additional ports for host connections, refer to Selecting Ports for Additional Host Connections for guidelines. If you need additional ports for internal storage connections, refer to Selecting Ports for Additional Storage Connections for guidelines.
The Sun StorEdge SIO-8 card has eight SC Fibre Channel (FC) ports. The FC ports are available for data host, internal storage, or external storage connectivity.
FIGURE 4-1 shows two SIO-8 cards installed in slots 3 and 4, and two MICs installed in slots 1 and 2 of the DSP.
The SIO-8 card FC ports are standard connectors and required SC optical cables.
The Sun StorEdge SIO COMBO card has six LC Fibre Channel (FC) ports and one
RJ-45 Gigabit Ethernet port. The FC ports are available for data host, external storage, or FC-based remote replication connectivity. The Gigabit Ethernet port provides connectivity to a wide area network (WAN) for Ethernet-based remote replication. For information about remote replication, see the online help.
FIGURE 4-2 shows two SIO COMBO cards installed in slots 3 and 4, and two MICs installed in slots 1 and 2 of the DSP.
The SIO COMBO card FC ports are small form-factor pluggable (SFP) connectors and require LC optical cables.
FIGURE 4-3 shows four SIO COMBO cards installed in slots 3, 4, 5, and 6 of the DSP. Two MICs are installed in slots 1 and 2.
FIGURE 4-4 shows a sample configuration of data hosts connected to the system through redundant SAN FC switches.
This example shows three data hosts connected to the system through redundant FC switches. Each host connects to a primary and alternate FC switch. The primary FC switch connects to port C/1. The secondary FC switch is connected to port D/1.
For more information about the allocation of I/O ports for SAN and DAS hosts, see the online help. For information about connecting external storage devices, see Chapter 6.
The Sun StorEdge 6920 system supports direct attached storage (DAS), allowing data hosts to connect directly to storage. FIGURE 4-5 shows an example of data hosts connected directly to the Sun StorEdge 6920 system.
This example shows each data host connected directly to ports C/1 and D/1, C/2 and D/2, C/3 and D/3.
For information about connecting external storage devices, see Chapter 6.
Ports in the columns on the service panel marked 1, 2, 3, and 4 are reserved for host or external storage connections. If you want to allocate more ports for host attachment, take additional ports from left to right and top to bottom.
For example, once you have used all ports in columns 1 through 4 (rows C and D of a two SIO-8 card configuration), add the next host connections to column 5 (rows C and D). If your system has a four SIO-8 card configuration, add the next host connections to column 5 (rows A and B), and then add the next connections to column 5 (rows C and D).
|
Note - You cannot use ports in column 8 of the service panel for host connections. |
|
Note - If you allocate more ports to data hosts than to internal storage, you will need additional 1-meter LC-to-SC cables for each HBA port to physically connect the DSP to the service panel. |
Ports in the columns on the service panel marked 8, 7, 6, and 5 are reserved for internal storage connections. If you want to allocate more ports for internal storage, take additional ports from right to left and top to bottom.
For example, once you have used all ports in columns 8 through 5 (rows C and D of a two SIO-8 card configuration), add the next internal storage connections to column 4 (rows C and D). If your system has a four SIO-8 card configuration, add the next internal storage connections to column 4 (rows A and B), and then add the next connections to column 4 (rows C and D).
|
Note - You cannot use ports in column 1 of the service panel for internal storage connections. |
The Sun StorEdge 6920 System Host Installation Software CD contains software for Solaris data and management host stations. When you run the installation script, you select the functionality you want to install, and the script installs the required packages. You can choose from the following options:
Sun StorEdge SAN Foundation software incorporates kernel drivers and utilities that enable the data host to connect to, monitor, and transfer data on a SAN.
Storage Automated Diagnostic Environment Enterprise Edition is a distributed diagnostic monitoring tool for SAN devices, including data hosts and external storage devices connected to the Sun StorEdge 6920 system.You can configure the software to monitor on a 24-hour basis, collecting information that enhances the reliability, availability, and serviceability (RAS) of the storage devices.
The remote scripting CLI client provides access to the same configuration and monitoring tasks that you perform through the browser interface. You can also write scripts using the sscs commands to automate configuration and management tasks. You can install the remote scripting CLI client on a data host or an external management host. See the sscs(1M) man page for information about the remote scripting CLI commands.
The remote scripting CLI client is also available for Windows, Red Hat Linux, AIX, and HP-UX operating environments (see Installing the Remote Scripting CLI Client).
|
Note - See the Sun StorEdge 6920 System Release Notes for the operating system versions that are supported. |
TABLE 4-2 provides a summary of the tasks for installing the host software.

Installing Host Software for Operating Systems Other Than Solaris OS |
TABLE 4-3 lists the hardware and software that must be set up and installed before you can install the data host software on a Solaris OS data host.
The installation script checks for the required versions of the following software packages and patches:
SDK Environment version 1.4.2
If the installation script does not find the correct version of the required software, it either upgrades an existing version of the software, installs the required version of the software in a new location, or stops the installation process. Appropriate messages are provided at each step of the installation process informing you of the action being performed.
If the installation script finds an earlier version of SAN Foundation software, you must remove the current version of SAN software. The installation script installs the required version of SAN Foundation software and all required patches.
The SAN Foundation software and Java Web Console are embedded in the Solaris 10 OS. Therefore, when you install the data host software on a Solaris 10 platform, only the Storage Automated Environment Enterprise Edition software is installed.
If a data host is running Storage Automated Diagnostic Environment Enterprise Edition version 2.2 software or earlier, do the following before running the installation script:
If a data host is running Storage Automated Diagnostic Environment Enterprise Edition version 2.3 software or later, the installation script upgrades the currently installed version to version 2.4.
The installation script checks for the Java SDK version 1.4.2 software, which is required by the remote scripting CLI client. If the required version is not found, the installation script installs Java SDK version 1.4.2 in /opt/se6000/java.
Before you run the installation script, check the version of Java SDK that is installed on the management station. If a version earlier than Java SDK version 1.4.2 is installed, refer to the online compatibility documentation at the following site for information about incompatibilities:
http://java.sun.com/j2se/1.4.2/compatibility.html
You must install the software as superuser (root). If aliases exist in the superuser environment or profile, the software installation and configuration might have unexpected results. Remove any aliases created for the environment (for example, cp="cp -i") before you install or configure the software.
