• Using a RAID array controller in transparent failover mode allows the use of hardware RAID to mirror the disks. However , without a second SCSI bus, second Memory Channel, and redundant networks, this configuration is still not a NSPOF cluster (Section 1.5.4). • By using an HSZ70, HSZ80, or HSG80 with multiple-bus failover enabled you can use[...]

Note that in the configuration shown in Figure 1 – 6, there is only one shared SCSI bus.

Up to two UltraSCSI bus segments may be coupled together with UltraSCSI hubs or signal converters, increasing the total length of the UltraSCSI bus. 3.2.2 T ransmission Methods T wo transmission methods can be u[...]

Y ou cannot use a DWZZA or DWZZB signal converter at UltraSCSI speeds for T ruCluster Server if there are any UltraSCSI disks on the bus, because the DWZZA or DWZZB will not operate correctly at UltraSCSI speed. The DS-BA35X-DA personality module contains a signal converter for the UltraSCSI BA356. It is the interface between the shared differentia[...]

______________________ Note _______________________ If you are using a DS-DWZZH-05 UltraSCSI hub with fair arbitration enabled, SCSI ID numbering will change (see Section 3.6.1.2). Use the following priority order to assign SCSI IDs to the SCSI bus adapters connected to a shared SCSI bus: 7-6-5-4-3-2-1-0-15-14-13-12-11-10-9-8 This order specifies t[...]

Because of the cable length limit, you must plan your hardware configuration carefully , and ensure that each SCSI bus meets the cable limit guidelines. In general, you must place systems and storage shelves as close together as possible and choose the shortest possible cables for the shared bus. 3.5 T erminating the Shared SCSI Bus When Using Ultr[...]

3.6.1.2.2 DS-D WZZH-05 Fair Arbitration Although each cluster member system and storage controller connected to an UltraSCSI hub are on separate SCSI bus segments, they all share a common SCSI bus and its bandwidth. As the number of systems accessing the storage controllers increases, it is likely that the adapter with the highest priority SCSI ID [...]

3.6.1.2.3 DS-D WZZH-05 Address Configurations The DS-DWZZH-05 has two addressing modes: wide addressing mode and narrow addressing mode. W ith either addressing mode, if fair arbitration is enabled, each hub port is assigned a specific SCSI ID. This allows the fair arbitration logic in the hub to identify the SCSI ID of the device participating in [...]

9.4.3.2 Cabling an HSZ20 in a Cluster Using External Termination T o connect a SWXRA-Z1 (HSZ20 controller) to a shared SCSI bus, follow these steps: 1. Referring to the RAID Array 310 Deskside Subsystem (SWXRA-ZX) Hardware User ’ s Guide , open the SWXRA-Z1 cabinet, locate the SCSI bus converter board, and: • Remove the five differential termin[...]

2. Attach the trilink with the terminator to the controller that you want to be on the end of the shared SCSI bus. Attach an H885-AA trilink connector to the other controller . 3. Install a BN21K or BN21L cable between the H885-AA trilink connectors on the two controllers. The BN21L-0B is a 0.15-meter cable. 4. If you are using a DS-DWZZH-05: • V[...]

10 Configuring Systems f or External T ermination or Radial Connections to Non-UltraSCSI Devices This chapter describes how to prepare the systems for a T ruCluster Server cluster when there is a need for external termination or radial connection to non-UltraSCSI RAID array controllers (HSZ40 and HSZ50). This chapter does not provide detailed infor[...]

Follow the steps in T able 10 – 1 to start the T ruCluster Server hardware installation procedure. Y ou can save time by installing the Memory Channel adapters, redundant network adapters (if applicable), and KZPSA-BB or KZPBA-CB SCSI adapters all at the same time. Follow the directions in the referenced documentation, or the steps in the referen[...]

The DWZZH-series UltraSCSI hubs are designed to allow more separation between member systems and shared storage. Using the UltraSCSI hub also improves the reliability of the detection of cable faults. A side benefit is the ability to connect the member systems ’ SCSI adapter directly to a hub port without external termination. This simplifies the[...]

_____________________ Note _____________________ Y ou may have problems if the member system supports the bus_probe_algorithm console variable and it is not set to new . See Section 2.3.2.
