Connecting the cables

Fiber optic cables are used to connect the HP StorageWorks MSA1000 to interconnect devices, such as hubs and switches, and if additional storage enclosures are being used, SCSI cables are used to connect the HP StorageWorks MSA1000 to the additional storage enclosures.

Fiber optic cables used will differ, depending on the components and devices being connected. The HP StorageWorks MSA1000 and all of its embedded components use a 2 Gb/s Lucent connector (LC). Depending on the connector in the HBAs, external switches, or hubs, a 1 Gb/s subscriber connector (SC) or a 2 Gb/s LC connector will be needed on the non-HP StorageWorks MSA1000 end of the cable.

SCSI cables are used to connect up to two additional external storage enclosures to the HP StorageWorks MSA1000. Use standard VHDCI SCSI cables of appropriate length.

Because there are two interconnect devices and HBAs in redundant configurations, cable connections must follow exacting installation requirements. See the illustrations later in this document for examples.

Fiber optic cables

Multi-mode fiber optic cables are capable of supporting distances of 2 m to 500 m (6.56 to 1640.42 feet) at 1 Gb and up to 300 m (984.25 feet) at 2 Gb. These cables are for use with short-wave transceivers only. Several multi-mode fiber optic cable option kits are available from HP. Each kit contains a multi-mode fiber optic cable with either a 1 Gb/s or a 2 Gb/s connector attached to each end.

For cables greater than 15 meters, contact an independent fiber optic cable supplier.

If you use an existing 62.5-micron optical cable, you must obtain a 62.5-micron jumper from an independent source. A 50-micron cable cannot be spliced with a 62.5-micron cable. In addition, these cables support half the maximum allowable distance of the multi-mode cables.

Figure 1 provides an illustration of the different connectors.

Figure 1: 2 Gb/s and 1 Gb/s connectors

Cable installation considerations

To ensure the cabling in the back of a rack system does not interfere with system operation or maintenance, gather the cables in the rear of the HP StorageWorks MSA1000 and bind them loosely with cable ties. Route the excess cables out of the way, along the side of the rack. See Figure 2 for an illustration.

When the cables are tied together and the excess cable is routed away from the HP StorageWorks MSA1000, system components and indicators are easily visible and accessible.
CAUTION: Do not overtighten the cable ties. Damage to the optical cables may result.
CAUTION: Make certain the fiber optic cables are installed and supported so that no excess weight is placed on the fibre channel connectors. This is necessary to prevent damage to the connector and cable and to prevent a cable bend radius less than 7.62 cm (3 inches) at the connector and along the cable length. Excess fiber optic cable should be coiled and tied out of the way, being careful not to coil the cable in a tight loop with a bend radius of less than 7.62 cm (3 inches).

Installing support software

Support software includes HBA drivers as well as the ACU, Insight Manager 7, and Compaq Analyze components that were discussed previously in this document. After the HP StorageWorks MSA1000 is installed and connected to the server, you can load the needed software components onto the server.

HBA drivers

All servers that will access the HP StorageWorks MSA1000 must have the appropriate HBA drivers installed. Drivers for Windows, Linux, and NetWare environments are located on the Modular SAN Array 1000 Support Software CD, shipped with the HP StorageWorks MSA1000. For instructions on installing these drivers, refer to the HP StorageWorks Modular SAN Array 1000 Quick Installation Guide included with the CD in the HP StorageWorks Modular SAN Array 1000 Setup and Management kit.

The HBA drivers for OpenVMS and Tru64 UNIX environments are built into their operating systems. To obtain the latest version of the operating system, use your normal support channels.

Array Configuration Utility

If your operating system supports the ACU and you plan to use the ACU to configure the storage of the HP StorageWorks MSA1000, it may be loaded from the HP StorageWorks MSA1000 Software Support CD onto the server. For instructions on installing the ACU, refer to the HP StorageWorks Modular SAN Array 1000 Quick Installation Guide included with the CD in the HP StorageWorks Modular SAN Array 1000 Setup and Management kit.

Insight Manager 7

If you are running in a Windows, Linux, or NetWare Linux environment, you can use Insight Manager 7 to monitor the performance of your storage system. Install Insight Manager 7 as instructed in the literature provided with your Insight Manager 7 purchase.

Compaq Analyze

If you are running in an OpenVMS or Tru64 UNIX environment, you can use Compaq Analyze to monitor your storage system. If Compaq Analyze is not already loaded on your server, install it as instructed in the literature provided with Compaq Analyze.

Configuring the switches, routers, and servers

Before the HP StorageWorks MSA1000 can be accessed, the switches, routers, and servers must be set up. Configuration tasks may include entering the IP addresses and other parameters, setting up zoning on the switch, establishing a workgroup or domain environment, and establishing cascading patterns.

For information on configuring the embedded HP StorageWorks MSA SAN Switch 2/8, refer to the HP StorageWorks MSA SAN Switch 2/8 Installation Guide.

For information on setting up external switches and routers as well as the servers, refer to their respective user manuals.

Setting up and configuring the storage
After the servers and interconnect devices are set up and the HP StorageWorks MSA1000 is physically installed, the storage of the HP StorageWorks MSA1000 can be accessed and configured. Storage configuration steps include the following:
  • Determining a Storage Plan

  • Configuring the Storage Arrays and Logical Volumes

  • Setting up and Configuring SecurePath in Redundant Configurations

Determining a storage plan

Planning the storage configuration is critical to the successful and efficient deployment of the HP StorageWorks MSA1000. Plans should include decisions about total system capacity, fault-tolerance and striping methods of the arrays, sizes of the arrays, and plans for future growth.

Configuring the storage arrays and logical volumes
After a storage plan is developed, configure the storage by using the available user interfaces of the HP StorageWorks MSA1000. Depending on the server operating system and user preference, the available user interfaces include the ACU and the CLI.
Operating system

The ACU and the CLI user interfaces are documented in separate sections of this guide.

For information on using the ACU, see the "Array Configuration Utility (ACU)" chapter of the Users Guide.

For information on using the CLI, see the "Command Line Interface (CLI)" chapter of the Users Guide.

Setting up and configuring SecurePath in redundant configurations

For Windows, Linux, and NetWare operating systems, redundant configurations with duplicate array controllers, interconnect devices, and HBAs must use SANworks SecurePath software to ensure continuous data availability.

SecurePath eliminates the hard drive, array controller, interconnect hardware, and HBA as single points of failure in the storage system. These redundant physical connections define separate physical paths. If any component in the path between the host and the storage fails, SecurePath ensures availability by redirecting pending and subsequent requests to an alternate path.

For information on using SecurePath, refer to the documentation provided with your SecurePath software.

NOTE: SecurePath is not needed or supported for OpenVMS and Tru64 UNIX operating systems, because multipath capability is built into these operating systems.

Identifying the server host mode

For all operating system environments, after the arrays and logical volumes have been created, each server’s operating system must be identified to the HP StorageWorks MSA1000.

The host mode can be set in both the ACU and the CLI.

For information on setting the host mode using the ACU, see the "Array Configuration Utility (ACU)" chapter of the Users Guide.

For information on setting the host mode using the CLI, see "Managing Connection Profiles in the Command Line Interface (CLI)" chapter of the Users Guide.

HP StorageWorks MSA1000 sample configurations

Because the HP StorageWorks MSA1000 supports a variety of embedded and external switches and hubs in standalone and clustered deployments, many configuration options exist. This section illustrates possible configurations using the following interconnect options:
  • Fibre Channel I/O Module Configurations

  • Embedded MSA SAN Switch 2/8 Configurations

  • Embedded MSA Hub 2/3 Configurations

NOTE: Redundancy and cluster support is possible in all configurations.

Redundant configurations are used to ensure uninterrupted availability of data. Complete duplication of all hardware components is a requirement of a redundant configuration. This duplicity includes using two HP StorageWorks MSA controllers, and at least two interconnect devices (depending on the configuration this may include the HP StorageWorks MSA Fibre Channel I/O Modules, MSA SAN Switch 2/8s, MSA Hub 2/3s, or external switches or hubs), and HBAs in the server. As mentioned previously, the fiber cables must be connected in a precise manner to provide the multiple paths required when rerouting data.

The following illustrations provide samples of possible configurations, and are in no way comprehensive.

Fibre channel I/O module configurations

When using the included Fibre Channel I/O Module, the HP StorageWorks MSA1000 will usually be connected to an external switch or hub. In Windows, Linux, and NetWare environments only, the HP StorageWorks MSA1000 can be connected directly to a server.

Fiber optic cables are used to connect the HP StorageWorks MSA1000 to the server and SCSI cables are used to connect the HP StorageWorks MSA1000 to the additional storage enclosures.

Figure 3 illustrates this basic configuration of connecting one server directly to the fibre channel I/O module of the HP StorageWorks MSA1000.

Figure 3: I/O module directly connected to a server

Another common configuration includes connecting an external SAN switch to the fibre channel I/O module of the HP StorageWorks MSA1000.

Figure 4 illustrates multiple servers and multiple HP StorageWorks MSA1000s connected to a SAN switch in a non-redundant configuration.

Figure 4: I/O module connected to an external switch, non-redundant configuration

When a redundant configuration is set up using external SAN switches, two HP StorageWorks MSA1000 controllers, two fibre channel I/O modules, two SAN switches, and two HBAs in each server are required.

Figure 5 illustrates the cable connections of a redundant configuration when external SAN switches are connected to the Fibre Channel I/O modules of the HP StorageWorks MSA1000.

Figure 5: I/O module connected to an external SAN switch, redundant configuration

Embedded HP StorageWorks MSA SAN switch 2/8 configurations

The following illustrations provide examples of an HP StorageWorks MSA SAN Switch 2/8 installed in the HP StorageWorks MSA1000.

Figure 6 shows the HP StorageWorks MSA1000 in a non-redundant configuration and Figure 7 shows the HP StorageWorks MSA1000 in a redundant configuration.

Figure 6: HP StorageWorks MSA SAN switch 2/8, non-redundant configuration

Figure 7: HP StorageWorks MSA SAN switch 2/8, redundant configuration

Embedded HP StorageWorks MSA Hub 2/3 configurations

Another basic configuration of the HP StorageWorks MSA1000 includes using the HP StorageWorks MSA Hub 2/3 option to connect two servers to the storage in a redundant, possibly clustered environment.

Figure 8 is an illustration of this redundant configuration using the embedded hub.
