Chapter One Introduction Voyager 3000 Family The Voyager 3000 is a cost effective open architecture RAID solution. All Voyager 3000 systems include 8MB EDO cache memory, redundant power supplies (PSUs) and dual advanced cooling modules (ACM’s) per shelf as standard. The Voyager 3000 series is available in tower, rackmount and fault tolerant solutions1 . The model number and descriptions are shown in Table 1-1, Table 1-2 and Table 1-3.
Voyager 3000 User Guide Table 1-4 Host Connection Codes FW FWD UW UD Fast Wide single ended Fast wide differential Ultra SCSI wide Ultra SCSI wide differential VRA-3001T-XX-Y The VRA-3001T-XX-Y is typically used as an entry level RAID system where a large data capacity is not required. The RAID controller is separate to the host system and is platform independent. It is mandatory that a SCSI bus is available at the host side which will connect to the host interface of the controller.
Introduction Figure 1-2 Internal bus configuration of VRA-3001T-XX-Y VRA-3002T-XX-Y This is a twin tower RAID configuration made up of a single controller and 13 drives as shown in Figure 1-3.
Voyager 3000 User Guide This system will typically be used in similar situations to that described within the VRA3001T-XX-Y section on page 1-2 but with larger capacity requirements. The VRA-3002T-XX-Y is configured as two SCSI buses. The first SCSI channel is connected to the top three drives in the first shelf (left hand side) which are set up as SCSI Ids 0à2. The cable is then routed to the top four drives in the second shelf. These drives are set up as SCSI Ids 3à6.
Introduction VRA-3001R-XX-Y This system will be used in a rackmount configuration and will normally be part of an expandable system. Customers can add rackmount systems subject to cabinet limitations. Figure 1-5 shows three systems mounted in a standard 19” cabinet. Each shelf is similar in configuration to the VRA-3001T-XX-Y described earlier and is made up of six storage bays, a single host connection and one RAID controller. The shelves take 3 U of cabinet space.
Voyager 3000 User Guide VRA-3002R-XX-Y This system is similar to the VRA-3002T-XX-Y and is used for expandable storage. Each shelf has a measurement of 3 U and may easily be integrated into a standard 19” rackmount system. The system is made up of twin shelves, 13 storage bays, a single host connection and one RAID controller. Figure 1-6 shows two hosts connected to two VRA-3002R-XX-Y systems. In this and the previous case the hosts are completely separate entities and do not share the data in any way.

Introduction The industry standard SCA2 connector is used to interface between the device and the backplane. SCA features staggered contact pins and insertion guidance. All signals such as SCSI, Ids, Power etc. are carried through the SCA. This lowers cost, enhances reliability and fully conforms to the Ultra SCSI specification. RAID Basics RAID stands for Redundant Array of Independent Disks3.
Voyager 3000 User Guide RAID 3 Block Striping with Dedicated Parity - Data is broken into logical blocks, the size of a SCSI disk block, and striped across several drives. One drive is dedicated to parity. In the event of failure, original data is re-generated from the parity information.
Chapter Two Installation and Setup Unpacking and Initial Setup On receipt of the system visually inspect the exterior of the packaging for any signs of damage. If any damage is found the carrier and Eurologic must be notified immediately who will advise you of the appropriate action. The cartons are sealed via packaging tape which should be cut open in the normal manner. Remove the top foam layer from each box and exercise caution when lifting out the components.
Voyager 3000 User Guide Electrical Considerations Circuit Overloading Care should be taken to ensure that the current does not exceed the rating of the power source circuitry. This includes cabling, power distribution units, filters and any other components through which the main A/C flows.
Installation and Setup A ground point for securing the braid is provided at the rear of the rack and is shown in Figure 2-2. Figure 2-2 Rear view of rack showing ground point Setting the host SCSI Ids For information relating to setting up the host ID refer to page 4-18. Setting the target SCSI Ids This section refers to configuration of the SCSI target bus IDs on the backplane. These are factory set when the system is shipped and should not normally be altered.
Voyager 3000 User Guide Figure 2-3 Rear view of single tower showing host connections 2. Refer to Figure 2-4 and remove the ACMs by unscrewing the large single screw, swinging back and unclipping the snap on wiring connector. Figure 2-4 Rear view showing ACMs, cowl and shield 3. Remove the shield by unscrewing the large flathead screw from the cowl.
Installation and Setup The switches are now accessible at the middle of the backplane on the right hand side when looking at the rear of the system as shown in Figure 2-5. Figure 2-5 Setting the Target Bus SCSI IDs The SCSI Ids may be set to have a base address of either 0 or 3. Setting the switch to the left (when viewed from the rear) will cause the drives associated with that switch to occupy SCSI Ids 0à 2. Setting the switch to the right will cause the drives to occupy SCSI Ids 3à5.
Voyager 3000 User Guide Figure 2-7 Location of DPS1 on VRA-3002 second backplane Switch positions 1-4 are used to set the starting ID for the first device (bay 0) on the bus. Devices in bays 1,2 and 3 will automatically increment this ID by one in turn5. For example if the device in bay 0 is set to be at SCSI ID 3 then the device in bay 1 will automatically appear as ID 4, the device in bay 2 will appear as ID 5 and the device in bay 3 will appear as ID 6.
Installation and Setup Figure 2-8 SCSI ID Switch (DPS1) SW-1 of DPS1 corresponds to the L.S.B. of the ID of the device in bay 0, whilst SW- 4 corresponds to the MSB of the ID of the device in bay 3. SW- 5 of DPS1 corresponds to the L.S.B. of the device in bay 4, whilst SW- 8 corresponds to the MSB of the ID of the device in bay five. Table 2-1 shows the switch settings along with their corresponding Ids, the default6 settings are shown in bold text.
Voyager 3000 User Guide Table 2-1 SCSI ID switch settings for the second backplane in a VRA-3002 configuration.
Installation and Setup Note Ultra SCSI has very stringent requirements regarding cable length. Any cables connected to Ultra devices must conform to Ultra SCSI specifications. When there are excess of 4 devices cable length should be no greater than 1.8 metres for single ended Ultra SCSI. The implication of this is that for any Ultra SCSI system the initiator and target will try to transfer data at Ultra SCSI rates during the initialisation process regardless of the number of devices and cable length.
Voyager 3000 User Guide SCA attachment To connect an SCA device to a device carrier simply insert the SCA device and connect it via the 4 screw holes provided on the underside of the device carrier. There are also device carriers for other devices. Table 2-3 shows the carrier part numbers. Table 2-3 Device carrier Device Part Numbers Description Part Number Device carrier Standard 3.5” non SCA wide drive VOY-W-AA Device carrier Standard 3.5” non SCA narrow drive VOY-N-AA Device carrier Standard 3.
Installation and Setup Figure 2-11 RAID Controller Access to the controller is obtained by removing the four screws at the side of the top panel. This will allow access to the main board. Removing the piggy-backed channel cards reveals Figure 2-12 Main board access Power Socket Channel 0 Simm Module CPU the topography of the main board as shown in Figure 2-12.
Voyager 3000 User Guide • • Use 72-pin 60 Ns DRAM or EDO SIMM. Maximum DRAM size is 32 MBytes in one 32 MByte SIMM. Installation of SIMMs is accomplished by the following steps: 1. Power off the system and disconnect the power connector. 2. Refer to Figure 2-13 Insert the DRAM SIMM vertically with the key to the left (1). Then, push towards the back until the hooks on both sides of the socket snap into place (2) as shown below.
Installation and Setup Refer to Figure 2-15 and remove the ACMs by unscrewing the large single screw, swinging back and unclipping the snap-on wiring connector. Figure 2-15 Rear view of ACM assembly Installation of an ACM is simply a reversal of the above procedure. Component Insertion and removal Drive Insertion Push the device firmly into the device bay slot. Do not attempt to slam it into position. Ensure that the button at the front of the carrier is fully extended after device insertion.
Voyager 3000 User Guide PSU Insertion and Removal The VOYAGER 3000’s power supply is designed for hot pluggable operation. To achieve this temperature sensitive current limiting is used. As the temperature to the devices increase the current limiting function decreases. This will prevent undesirable surges. If removing and replacing the same PSU please ensure that at least one minute has elapsed between removal and re-insertion which will allow components to cool to ambient temperature.
Environmental Monitoring Unit Chapter Three EMU Environmental Monitoring Unit Configurations Introduction The Environmental Monitoring Unit ( EMU ) is a multifunction plug-in daughter card that allows a user to monitor the operational status of a Voyager 3000 system. There is one EMU per storage shelf. The module provides visual and audible feedback of events to the user. In addition the EMU provides addressable memory locations which may be read or written to.
Voyager 3000 User Guide System Configurations Single Shelf configuration Figure 3-1 shows how a single shelf Voyager 3000 system is configured with an EMU. The system is set up with a device ID of 0 ensuring that it functions as a master device. Figure 3-1 Single shelf EMU configuration Dual shelf configuration In a dual shelf configuration the Host connects to the I2C Master via RS232 serial link. Data from the second EMU is requested via the I2C bus and is passed to the Host via the RS232 link.
Environmental Monitoring Unit Setting up the EMU The EMU is physically located at the rear of the device shelf. A magnified view of the EMU is shown in Figure 3-3. Figure 3-3 Location of EMU within the shelf A view of the PCB layout is shown in Figure 3-4. Figure 3-4 EMU PCB layout The switch settings for the Dip.

Environmental Monitoring Unit Connecting the EMU This section describes the procedure for connecting the EMU to the host system. It is possible to have up to eight EMUs connected together in a daisy chain configuration. The first EMU on the chain must be connected to the host system using the serial RS232 cable provided. The EMU ID for the first shelf in the chain must be set as ID 0 so that the system will see it as the master. All other EMUs connected on the chain will be seen by the system as slaves.

Chapter Four RAID controller configuration Controller Description The VOYAGER 3000 is a SCSI to SCSI RAID controller specifically designed to provide RAID 0, 1, 0+1, 3 or 5 capability to any host system equipped with a SCSI interface. It is totally independent of the host system's operating system with all the RAID functions performed by the controller hardware. In effect, it endows the host system with the high speed and fault-tolerant disk storage operation of RAID technology.

Figure 4-9 Windows Terminal Communication Settings Creating a logical volume A "Logical Drive" is a set of drives grouped together to operate under a given RAID level and appears as a single contiguous drive. The VOYAGER 3000 is capable of grouping connected drives into 8 logical drives, each operating on the same or different RAID levels.
RAID Controller Configuration Figure 4-10 Initial Screen Select Terminal (VT100) mode if following the instructions above and press e. This will display the screen shown in Figure 4-11. Figure 4-11 Main Menu Screen In the example shown the physical configuration consists of a single tower with 6 disk drives. The first task is to create a RAID set which is a logical drive as far as the host is concerned.
Voyager 3000 User Guide matches the actual configuration. This is done by selecting view and edit SCSI drives from the main menu as shown in Figure 4-12. Figure 4-12 Verifying Drive Configuration The controller displays six drives. Use the arrow keys to scroll down if necessary. The information reported by the VOYAGER 3000 includes the Vendor and Product ID of the drives as well as their capacity and RAID controller status. The example in Figure 4-12 shows six drives connected to the two target buses.
RAID Controller Configuration Pressing the e key will commence the operation of building a new logical drive. A dialogue will appear asking to Create Logical Drive, answering YES to this prompt brings up the screen shown in Figure 4-14 prompting the user to select the desired RAID level. Select the RAID 5 option and press the e key. Figure 4-14 Creating a logical drive A list of drives which are available for RAID set inclusion appears as shown in Figure 4-15.
Voyager 3000 User Guide Figure 4-16 Selecting drives for inclusion in a RAID set After the drives are selected we back up through the menus by pressing the v key. The next dialogue to appear prompts the user to assign the maximum capacity of the RAID set. In our example we will use all of the available drive capacity which is 4095MB. To alter the capacity press the e key and type in the desired value. Figure 4-17 shows the dialogue for entering the drive capacity.
RAID Controller Configuration Figure 4-19 Progress of RAID set creation Creating a Second Logical Volume There are three drives left unassigned and we will use two of them to create a 2 drive RAID 1 set. This will become the second logical drive. To do this we take the View and Edit Logical Drives option again from the Main Menu and highlight logical drive one position.
Voyager 3000 User Guide The status of the SCSI drives are shown by selecting the View and Edit SCSI Drives option from the Main Menu (Figure 4-11). A list of the SCSI drives and their status is shown, as in Figure 4-22. Figure 4-22 Viewing all Logical Drives The status table shows the first three drives as part of logical volume 0. These have a status of ON-LINE. In this case the available capacity will be 8190MB because the equivalent capacity of one of the drives is used for parity information.
RAID Controller Configuration Partitioning a Logical Volume Now that we have created two RAID sets we will partition them into logical volumes for the host CPU’s use. This is done by selecting View and Edit Logical Drives, selecting the logical volume to partition and press e. Select the Partition Logical Drive option from the menu shown in Figure 4-24. Figure 4-24 Allocating Capacities to partitions Answer YES to the dialogue and the logical drive partition table will appear as shown in Figure 4-25.
Voyager 3000 User Guide When all the available volume capacity has been divided up press the ESC key to exit. Mapping Host LUNs The next stage is to map these partitions to Logical Unit Numbers (LUNs) so that they will be visible from the host system. This is done by selecting View and Edit Host LUNs from the Main Menu. Answer YES to the prompt. In our case we are using SCSI channel 2 as our host channel so this appears for mapping as shown in Figure 4-27.
RAID Controller Configuration We are now presented with the choice of logical volumes to map. In this example we will map our first logical volume by pressing e with the logical volume 0 highlighted as shown in Figure 4-29. Figure 4-29 Selecting a Volume for LUN mapping A choice of logical volumes to map is given. Pressing e with a logical volume highlighted will bring up the partition table once again, and we then select each partition in turn for mapping, as in Figure 4-30.
