High performance InfoStation 12-bay SCSI-to-Serial ATA and FC-to-Serial ATA RAID enclosures are designed to support low-profile Serial ATA (SATA) or Parallel ATA (Ultra ATA/100)
drives for RAID applications. The SCSI-to-SATA enclosures (P/Ns S10H108 & S10H112)
support dual SCSI Ultra320 host channels and are downward-compatible with earlier SCSI
Wide Single-Ended or LVD interface technologies (i.e. Ultra2 or Ultra). Daisy-chaining chassis
for extended storage is also possible with optionally available SCSI Ultra320 repeater kits. The
FC-to-SATA enclosures (P/Ns S10K102 & S10K104) support dual Fibre Channel Arbitrated
Loops (FC-ALs) with 2Gbps operation.
Each standard 4U rack mount 12-bay RAID InfoStation chassis comes equipped with a RAID
controller, (12) removable drive carriers and an open 5.25" half-height device bay. These
enclosures are constructed of corrosion-resistant steel and each include (2) hot-swappable,
redundant 460W power supply modules and (2) hot-swappable, redundant, variable-speed
fan modules.
Both the SCSI-to-SATA and FC-to-SATA RAID chassis support RAID levels 0, 1, 0+1, 3, 5, 30,
and 50, and is OS independent. Online Capacity Expansion (OCE) and LUN support, up to
1GB DDR PC2100 SODIMM cache memory, as well as automatic hot swap, hot spare and
drive rebuild support are all included. An audible alarm on the InfoStation alerts the User to
system hardware failures and warning conditions. LED indicators at each drive bay provide
additional User feedback for drive activity, drive readiness and drive faults.

are many configuration options and variables (ie. host platforms, applications,
etc.), only general guidelines will be discussed in this User's Guide.
Refer to the disk manufacturer's documentation for specific information regarding the disks.
The InfoStation also incorporates "Soft Start" circuitry which eliminates in-rush current to each
of the installed drives during spin-up, as well as avoid power arcing during drive insertion.
A User Interface Module on the 12-bay InfoStation provides the User with a visual indication
of chassis configurations and communication statuses, in addition to providing an RS232
connection for system environmental monitoring, configuration and control. InfoMon®, a
downloadable chassis monitoring utility program, provides the InfoStation with a customizable,
web-based monitoring capability via the RS-232 serial connection. InfoMon includes a “Call
Home” feature, which enables chassis log information to be conveniently sent to a predetermined FTP site for trouble shooting and analysis. InfoMon also provides the User the ability to
easily configure both device and chassis settings with a few clicks of the mouse! Refer to
Appendix B for further information on InfoMon.

Mode Operation
The SCSI-to-SATA RAID Controller operates in three (3) modes:
• Self-Diagnostic Mode
• Configuration Mode
• Operation Mode
Self-Diagnostic Mode
To ensure flawless operation, the RAID Controller has a built-in self-diagnostic utility. SelfDiagnostic Mode occurs automatically upon power up, or after the RAID Controller has been
reset. During this mode, all components are tested and any potential problems are reported.
The Self-Diagnostic Mode runs three major diagnostic tests. The first diagnostic includes
testing the CPU and supporting core logic chips, the internal bus, memory, SCSI controller,
SATA controllers, and RS-232 controllers. The second diagnostic tests for the presence of
disks on each individual disk channel. It also checks the functionality of each disk found. The
final diagnostic tests the RAID functionality.
Configuration Mode
NOTE: The RAID Controller should be OFFLINE (disconnected from the host system)
Configuration Mode may be selected whenever <ENTER> is pressed during Operation Mode
or when the Monitor Utility is invoked from the remote terminal. In Configuration Mode, the user
is able to modify the settings of the RAID Controller and perform different functions to the
controller.
Entering a Password
If the password-check feature is enabled, the user will be prompted to enter a password
before proceeding (the default password is "00000000"). Refer to section "4 Password
Security" for information on how to change the default password.
The user may use the front control panel buttons to enter the password. Use the and
keys to scroll through the available characters, then press <ENTER> to select the character
and move to the next position. Once all the characters have been entered, press <ENTER>
to access the Configuration Mode.

Array Management
The unique RAID Controller array management firmware utilizes multi-tasking real-time kernel
technology to manage the controller. Additional features are real-time load analysis, online
diagnostics, event logging and broadcasting, and device inventory management.
RAID Levels
The RAID Controller supports RAID levels 0, 0+1, 1, 3, 5, 30, and 50. Depending on the
application that will be used, each RAID level offers a difference in performance, functionality,
and fault tolerance as shown in Table 6.
