    Active-Passive Mode In active-passive mode, there is one active and one passive RAID controller.

    Disadvantages Host HBA or the Fibre loop are single points of failure. In single host configuration, the host system is also a single point of failure. No upstream fail-over with a single host that has dual HBAs or dual host systems.

  • Page 126: Understanding Mirrored Operations

    DuraStor 412R/6320SS/7320SS Installation and User’s Guide Understanding Mirrored Operations The mirroring feature causes configuration changes to be mirrored to the opposite controller in an active-active configuration. The mirrored configuration is stored in the other controller’s firmware (Flash). If a controller fails and is replaced, then on boot up, it attempts to retrieve this configuration data from the opposite controller.

  • Page 127: Clustering

    Note: When Clear Configuration is selected in the Flash Utility menu, both the local Flash configuration and the other controller’s mirrored configuration image are cleared. Also, there is an option (J) in the Flash Utility menu that can be used to tell a booting controller to temporarily ignore the mirrored configuration.

  • Page 132: Active-Active Dual-Port Mode For San

    DuraStor 412R/6320SS/7320SS Installation and User’s Guide Active-Active Dual-Port Mode for SAN At the heart of this strategy is the active-active dual-port operating mode. In this mode, four fibre channel (FC) ports are simultaneously active when both controllers are online. In the event of a controller failure, two FC ports remain available to service all host I/O.

  • Page 133: Hubs Enabled

    SAN Solution Strategies (DuraStor 7320SS only) Hubs Enabled In Figures and B-2, the controllers are configured in an active- active dual-port mode with the internal hubs enabled. Two hosts are connected via two independent loops using the enclosure’s built-in hub bypass circuits. These circuits provide two internal hubs, eliminating the need for the use of external FC hardware, other than the cables.
  • Page 134 DuraStor 412R/6320SS/7320SS Installation and User’s Guide Figure B-2 illustrates the conditions when Controller 2 fails. Note that both hosts can still see Controller 1’s LUNs (LUN 1) and Controller 2’s LUNS (LUN 2). However, each host HBA can only see one LUN, instead of both.

  • Page 135: Hubs Disabled

    SAN Solution Strategies (DuraStor 7320SS only) Hubs Disabled Figures show two controllers configured in an active- active dual-port mode with the internal hubs disabled. Two hosts are connected via two independent switches. Using external switches supports higher bandwidth, since the host ports are not required to share bandwidth on a loop.

    SAN Solution Strategies (DuraStor 7320SS only) Active-Active Single-Port Mode for SAN In some scenarios, where the host has a single FC port and the SAN is not truly fault-tolerant, it may be desirable to configure the controllers in active-active single-port mode. Hubs Disabled (Single-Port Hosts and One Switch) Figure B-5 shows two single ported hosts connected to the two...
  • Page 138 DuraStor 412R/6320SS/7320SS Installation and User’s Guide In this case, there would be an advantage to configuring the controllers in active-active dual-port mode, because of increased connectivity. However, the host driver software would need to handle the fact that each LUN would appear twice in the SAN fabric, and that one image of the LUNs would disappear if one controller failed.

  • Page 139: Hubs Disabled (Single External Hub

    SAN Solution Strategies (DuraStor 7320SS only) Hubs Disabled (Single External Hub) Figure B-6 shows the hosts in a single loop configuration using an external hub. When a controller failover occurs, this configuration operates much the same as the previous one which uses a switch. The advantage is that a hub is less expensive.

  • Page 140: Hubs Enabled

    DuraStor 412R/6320SS/7320SS Installation and User’s Guide Hubs Enabled Figure B-7 shows hosts in a single loop configuration with the internal hubs enabled. The internal hubs eliminate the need for an external hub. It allows one or two hosts to be connected to the active-active storage enclosure without the cost of external hardware other than cables.

  • Page 141: San Configuration Not Supported

    SAN Configuration Not Supported In the active-active dual-port configuration with two independent hubs or the internal hubs, two single-ported hosts is not supported. The issue with this configuration is that if a controller fails, each host loses access to one of the LUNs. For example, if Controller 1 fails, Host 1 can no longer access LUN 2, because Port 2 on Controller 2 has changed from presenting its own LUNs to presenting Controller 1’s LUNs.
  • Page 142 DuraStor 412R/6320SS/7320SS Installation and User’s Guide The active-active strategy chosen allows a host to access two separate fibre channel ports (one from each controller) which are connected together via a switch or hub, in order to support access to LUNs owned by different controllers. This is simpler and provides higher performance than so-called “true LUN sharing”...

  • Page 195: Glossary

    Glossary active-active Active-active mode is when two controllers in an external subsystem cooperate to provide redundancy. If one controller fails, the remaining controller will take over the failed controller’s functionality. To accomplish this, each controller has two host SCSI ports, one of which is normally active, the other normally passive. In a failed-over configuration, the passive port becomes active and assumes the identity of the failed controller.
  • Page 196 DuraStor 412R/6320SS/7320SS Installation and User’s Guide controller A hardware device that performs I/O functions. Controllers also perform other functions such as read and write caching and RAID management. Also known as an adapter, embedded storage controller, or subsystem. disk array See array.
  • Page 197 Glossary fibre channel A high-performance connection standard designed for bidirectional, serial data communication. FC provides long- distance connectivity and high bandwidth for efficiently moving large data files. HBA (host bus adapter) An HBA is the critical link between a host server or workstation and a subsystem, integrating computing platforms, OSs, and I/O protocols to ensure proper interoperability and functionality.
  • Page 198 DuraStor 412R/6320SS/7320SS Installation and User’s Guide LVD (low voltage differential) LVD is a method of powering SCSI cables that will be formalized in the SCSI-3 specifications. LVD uses less power than the current differential drive (HVD), is less expensive, and allows for higher speeds such as those of Ultra2 SCSI.
  • Page 199 Glossary theory, any SCSI device can be plugged into any SCSI controller. See also HBA (host bus adapter). SCSI adapter A SCSI adapter is a 16-bit fast/wide or 8-bit narrow, single-ended or differential physical connection between a router and SCSI devices.
