  • Page 5: Chapter 1: Overview

    This document is the primary reference for the LSISAS6160 Serial Attached SCSI (SAS) switch. It describes the features of the switch and explains how to perform installation and physical configuration of the switch. The document also explains how to use both the web-based, and the command-driven SAS Domain Manager (SDM) utility interfaces to create storage configurations in the SAS domain.

  • Page 6: Serial Attached Scsi And The Sas6160 Switch

    SAS and SATA drives, and smaller cables and connectors. In SAS storage environments, the SAS6160 switch allows connection of multiple targets and initiators through a switched device for manageable scalability. The integrated SDM application provides a central management point to view the SAS topology, manage other switches or expanders in the domain, and to configure zoning to provide exclusive access between endpoints in the domain.
  • Page 7 In this simplified representation, the servers at the top of the diagram must access data on the storage devices in the lower part of the diagram. The SAS6160 switch manages the SAS configuration, allowing both servers to access all storage devices. Or, if zoning is used, single application servers can access specific storage devices exclusively.
  • Page 8 You can connect multiple SAS6160 switches in various topologies to provide failover support and to increase the number of connected devices in the SAS domain. The theoretical upper limit of SAS devices in a domain is 16,000. Each SAS6160 switch can handle 1000 SAS addresses.

  • Page 9: Sas Phys, Ports, And Connectors

    LSISAS6160 SAS Switch User Guide SAS Phys, Ports, and Connectors LSI Corporation September 2010 Flash Memory – Each LSISA2x36 expander connects to a parallel flash through the expander’s external memory interface. This flash is used for firmware storage and execution, as well as nonvolatile data such as Ethernet MAC address and SAS WWID.
  • Page 10 Figure 5: Narrow and Wide SAS Ports The SAS6160 switch has 64 phys, numbered 0 through 63. Each of the 16 SAS connectors on the switch case (numbered 0 through 15 in this document) contains four phys, making them wide ports.

  • Page 11: Sas Connectors And Cabling

    LSI Corporation September 2010 Use a separate crossover cable for each server, JBOD, RAID array, switch, or other device connected to the SAS6160 switch. Use Mini SAS 4x connectors (also called SFF-8088 connectors) on both ends of the crossover cables to connect the switch to all devices.

  • Page 12: Sas Routing And Zoning

    Page 12 SAS is a connection-oriented, point-to-point technology. When a host (initiator) issues a request to read or write data, the SAS6160 switch automatically determines how to route the connection request from the initiator to the correct data storage device (target).

  • Page 13: Creating Sas Zones

    LSISAS6160 SAS Switch User Guide 1.5.2 Creating SAS Zones LSI Corporation September 2010 The following figure shows a simple example of zoning. Figure 7: Simple Zoning Example You create SAS zones by first creating zone groups that include hosts or storage devices that share common access privileges, and zone sets that connect the zone groups together.
  • Page 14 The switch does not do this task automatically. Changes to the active zone set do not take effect until the zone set is updated and reactivated.

  • Page 15: Configuring Sas Zones

    LSISAS6160 SAS Switch User Guide 1.5.3 Configuring SAS Zones LSI Corporation September 2010 The following figure shows a sample configuration with three hosts and five JBODs. Figure 8: Configuration for Zoning Example Host 1 belongs to a local work group and accesses JBOD 1 as its primary resource. But Host 1 also accesses JBOD 2, JBOD 3, and JBOD 4, as a backup resource.

  • Page 16: Connecting Devices To The Sas6160 Switch

    Zone group 6 accesses zone groups 8 and 9, and vice versa. Zone group 7 accesses zone groups 9 and 10, and vice versa. The rules for connecting devices to the 16 SAS connectors on the SAS6160 switch are as follows: Any SAS initiator can be connected to any SAS connector on the switch.
  • Page 17 Figure 10: Example 1, Multiple Servers and JBODs A single rack can contain the switch and all the other devices. The configuration requires nine SAS cables with a Mini SAS connector on each end. Depending on the way in which zoning is set up for the devices, all servers could access data on all the JBODs, or servers could be restricted to accessing a subset of the JBODs.
  • Page 18 The third example (Figure 12) shows eight servers and one cascading switch connected to the SAS6160 switch. Several JBODs and RAID arrays connect to the other switch. NOTE: Example 5 and example 6 also show configurations with cascading switches.
  • Page 19 This dual porting configuration provides the server a redundant path through the switches for high availability. If one of the switches or connections fails, the server can still access the JBOD through the other connection. LSI Corporation September 2010 Page 19...
  • Page 20 You can use the SDM utility to modify and expand the storage configuration. NOTE: For zoning to function correctly, you must cable SAS6160 switches directly to one another, or through SAS 2.0 zoning expanders. Page 20 LSI Corporation September 2010...
  • Page 21 Example 6, Cascaded Switches Like in Example 3, the cables in this example can run from any connector of the downstream switch to any connector in the switch above it. The cascade sequence is limited to four switches. LSI Corporation...
  • Page 22 Example 7 (Figure 16) shows a star (tree) configuration of four switches, with switch B, switch C, and switch D connected directly to switch A. Like in Example 6, this example assumes that various SAS targets and SAS initiators are attached to the other connectors on the switches.)

    Install the SAS6160 switch in a site free from strong electromagnetic field generators (such as motors), vibration, and dust. Allow some space at the back of the switch (where the fans intake air) for proper ventilation. The AC power adapter is rated at 100 V to 240 V, and 50 Hz to 60 Hz.

  • Page 26 4. Finally, place the SAS6160 switch and its inline power supply on the shelf. The switch enclosure fits onto a raised rib on the shelf to hold it securely in place. When power is available at the connector side of the switch, route power cords along the enclosure on the far left or far right of the shelf.
