    This chapter describes the SNC (Storage Networking Controller) 4000. Overview The Scalar 24 enables customers to use and manage the library in a storage area network, via an integrated SNC 4000. When configured as a storage networking library, the Scalar 24 delivers the following functionality: •...

  • Page 12: Configuration Support

    Figure 1 Configuration Overview Configuration Support The SNC provides one FC interface. The FC interface is configured with a small form factor pluggable transceiver (SFP). In addition, the SNC has two Ultra2 SCSI interfaces. Address Mapping The SNC maps addresses across and between these different interfaces and preserves the persistency of the address maps across power ups of systems, devices, and the SNC.

  • Page 13: Ethernet

    The service port is used for local service and diagnostics when you use a terminal session to access the shell interface. The service port is configured at: • VT100 or ANSIW terminal emulation • 19,200 Baud SNC 4000 User’s Guide...

  • Page 15: Firmware 4.40 Features

    Firmware 4.40 Features This chapter describes the functionality of the Storage Networking Controller (SNC) Firmware 4.40. The SNC interface between storage and host provides Fibre Channel to SCSI connectivity. The SNC firmware enables you to map addresses across and between different interfaces, to configure private maps for security purposes, to condition the data path, and to preserve the persistency of the address maps when systems, devices, switches, and the SNC are turned on and off.

  • Page 16: Operating Environment

    All of these functions are embedded into a point and click interface designed to simplify management. The AMC receives information from Scalar storage networking libraries using the industry standard SNMP protocol. Because ADIC uses an industry standard protocol, information can be directed from ADIC libraries to framework applications.

  • Page 26: Host Registration Service

    Host Registration Service The Host Registration Service (HRS) is a small service/daemon installed on hosts which access the library. HRS simplifies security configuration and allows administrators to monitor host connections to the library. To accomplish this, HRS sends a periodic data pulse through the host’s Fibre channel HBA to the library. The pulse consists of the host’s WWN, network name, HBA type, and HBA driver level.

    Combining SFM with Channel Zoning Although it is possible to combine SFM and Channel Zoning, it is not recommended. SFM cannot assign access to LUNs on channels rendered inaccessible by Channel Zoning. If you do have a legacy Channel Zoning configuration, it is recommended that you edit the zones to permit all SAN Connections to have access to all SCSI channels, or you may end up with inaccessible devices that you had intended to be accessible.
