DUAL RAID CHANNEL CONFIGURATIONS

CAUTION: Offset VHDCI cable connectors must be used for proper fit. Failure to use

NOTES: StorCase recommends the use of SCSI Ports A-1 & A-2 on the I/O Repeater

proper cables may result in damage to the VHDCI connectors on the I/O repeater modules and Dual RAID Controller Module unit! RAID Controller "Kits" containing external I/O cables are available; contact StorCase for further ordering information.

VHDCI connectors are easily damaged by improper handling. Visually inspect each connector for bent contacts and carefully align prior to insertion.

Modules when configuring typical RAID channels (as shown in Figures 7, 8, & 9). In the special cases where extra length cables are required (up to 12m maximum), use Port B instead.

Controller A (Primary) disk channel SCSI ID (Initiator ID) is factory set to SCSI ID7. DO NOT configure any other devices to ID7 on the disk channel, or the configuration will fail to operate!

Controller B (Secondary) disk channel SCSI ID (Initiator ID) is factory set to SCSI ID6. DO NOT configure any other devices to ID6 on the disk channel, or the configuration will fail to operate!

StorCase does not recommend changing the factory default Initiator ID(s).

Up to 15 disks per SCSI channel with stand-alone RAID Controller Module unit installed (15 Disks x 4 Channels = 60 Disks Total).

Up to 14 disks per SCSI channel with dual RAID Controller Module unit installed (14 Disks x 4 Channels = 56 Disks Total).

Default operating mode for the Dual RAID Controller Module unit is Active- Passive.

Default operating mode for the Single RAID Controller Module unit is Stand- Alone Dual Port.

Default operating mode for the Single RAID Controller Module upgrade is Stand-Alone Dual Port.

If upgrading a Single RAID Controller Module unit with the Single RAID Controller Module upgrade (to a Dual RAID Controller Module configuration), make sure to reconfigure the operating mode accordingly.

I/O Repeater Modules must be used in conjunction with the FC-to-SCSI RAID Controller Module unit.

12 Installation

CAUTION: DO NOT bend the LC (optical) cable beyond the cable's minimum bend

radius, data transmission degradation may occur. Follow cable manufacturer's guidelines for bend radius limitation.

WARNING: DO NOT look directly into the open end of an active LC (optical) cable or

optical SFP module (with plugs removed)! Serious eye damage can occur from direct exposure to the infrared light!

NOTES: HSSDC2 (copper) SFP modules support 1Gbps operation only.

LC (optical) SFP modules support both 2Gbps and 1Gbps operation.

When in Active-Active mode, the dual controllers communicate with each other using SCSI Initiator IDs 6 & 7 on the disk channels. IDs 6 & 7 are factory set to ensure optimum communication between the two controllers. These IDs cannot be changed while in Active-Active mode. DO NOT configure any other devices to IDs 6 & 7 on the disk channels, or the Active-Active configuration will fail to operate!

Refer to section "Working with Operating Modes" for further information on Operating Modes.

Description

This option allows the controller to operate with two host ports. In this mode, the same LUNs display on the two separate host ports. Stand-Alone Dual Port mode allows the host to achieve greater throughput by balancing I/O operations across the two host ports. Host port fault tolerance is also achieved, since the host can continue accessing the controller if one host channel fails.

This option allows both controllers to operate independently and in an active-active pair. Active-Active modes allow two controllers to cooperate in system operation in a fault-tolerant manner. If one controller fails while in Active-Active mode, the other controller assumes its activities, allowing host access to continue.

When both controllers are online, each controller presents its LUNs on only one port.

When both controllers are online, each controller presents its LUNs on both ports, permitting redundant host access to all LUNs when there is a failure between host and controller. After failover, one port of the surviving controller presents Controller As LUNs and other port presents Controller Bs LUNs.

When changing to this mode on one controller, both controllers must be rebooted at the same time. Upon reboot, both controllers will automatically be in Active-Active Dual Port mode

This option allows the use of just one controller, with the second controller acting only as a backup (in case of a failure of the controller in use).

When changing to this mode on one controller, both controllers must be rebooted at the same time. Upon reboot, both controllers will automatically be in Active-Passive Dual Port mode
