1. Introduction

1.1 Overview

The 12Gb/s SAS ARC-8028 expander module is designed with an integrated ARM Cortex-R4 processor for topology management functions such as discovery, enclosure and drive management, and LED management. The ARC-8028 expander module features three or four 12Gb/s SAS SFF-8644 connectors. It is designed to fit into a stand-alone box and can be installed in a 5.25" mounting shell. The ARC-8028 is ideal for enclosure customers that want to support up to 24/32 channels 12Gb/s SAS or 6Gb/s and 3Gb/s SAS/SATA JBOD function units using SFF-8643 SAS cables. The ARC-8028 firmware has been included the failover to utilize the most up-to-date technology available, providing your system with reliable, high-quality performance. User can configure ARC-8028 redundant mode with multiple expander module using either RAID controllers or HBAs to achieve failover protection.

Unparalleled Performance

The ARC-8028 series expanders include 24/32 internal plus 12/16 external 12Gb/s SAS ports connection for host and easy expansion. High performance architecture sets new boundaries of industry performance expectations: 12Gb/s SAS or 6Gb/s and 3Gb/s SAS/SATA. The ARC-8028 incorporates the latest enhancements in SAS along with new LSI DataBolt bandwidth optimizer technology. This is designed to help facilitate the industry transition to 12Gb/s SAS-enabled systems by allowing users to take advantage of 12Gb/s speeds while utilizing existing 6Gb/s drives and backplanes. Using DataBolt, the ARC-8028 buffers 6Gb/s data and then transfers it out to the host at 12Gb/s speeds in order to match the bandwidth between faster hosts and slower SAS or SATA devices.

Maximum Interoperability

Areca presents its ultra-high performance and high reliability 12Gb/s SAS expander module for a cost-effective and enterprise-class JBOD storage enclosure. A 12Gb/s SAS expander module literally expands the number of end devices that you can connect

together. Expander devices, typically embedded into an expander module to connect system backplane, support large configurations of SAS end devices, including SAS host/RAID adapters and SAS and SATA disk drives. The SAS protocol defines a mechanism that has been implemented in the SAS expanders to guarantee fair access between drives in a domain. With ARC-8028 SAS expander, you can build large and complex storage topologies.

Easy Management

The expander box contains an embedded expander manager that can access via in-band SES-2 over SMP protocol and out-of-band RS-232 port. An out-of-band serial port is available for managing the configuration and monitoring the expander. The preferred I/O connection for server and JBOD backplanes is the internal Mini SAS HD SFF-8643 connector. This connector has eight signal pins to support four SAS/SATA drives and six pins for the SFF-8485 compliant SGPIO side-band signals. The Areca expander firmware and EPLD has implemented the SES-2 protocol and disk activity map to SGPIO based indicator LEDs. For backplane without SGPIO supporting, the expander box also provides two kinds of alternative LED cable header to support the individual fault/activity status indicator for those backplanes. In addition to meet different enclosure, ARC-8028 expander box has implemented autonomous chassis management of two power supplies status connectors, four fan monitor/speed control connectors through the SES-2 protocol. Firmware and configuration data including vendor identification strings can be customized or tuned for each customer.

2.3 Installation

The ARC-8028 expander box housed in a 5½-inch half-height canister with a removable LCD module, a host channel, two expander and a RS-232 CLI port controller. The expander controller is provided for customers who want to use the exiting SAS/SATA enclosure. It is designed to fit into one 5½-inch half-height drive bays located in a server chassis or storage case. Standard mounting holes are located on both sides of the controller canister. These mounting holes accept commonly available No. 6-32 coarse-thread screws. Use the following instructions below to install the ARC-8028 expander box.

Step 1. Power the Enclosure Off

Turn off the enclosure and remove the AC power cord. Remove the enclosure's cover. For the instructions, please see the enclosure documentation.

Step 2. Unpack ARC-8028 Expander Box

Unpack and remove the ARC-8028 expander box from the package. Inspect it carefully, if anything is missing or damaged, contact your local dealer.

Step 3. Mounting ARC-8028 Expander Box into the Enclosure

Remove the enclosure cover and find a 5.25 inch CD-ROM wide place to fasten the ARC-8028 expander box in the external enclosure. The expander box requires one 5.25" half-height drive bay.

Step 4. Connecting Expander Controller Power

The ARC-8028 series expander box supports 6 pin PCI-E power connector. If your power supply doesn't have a 6 pin PCI-E power cable then you can use the adapter to convert two 4 pin peripheral power cables into a PCI-E power cable. If you use an adapter then be sure to plug the 4 pin peripheral power connectors into separate power cables coming from the power supply.

Step 5. Install the LED Cable (Optional)

Please check the method which controls fault LED on the backplane. If the backplane supports SGPIO feature, ignore the individual fault LED cable connection. The preferred I/O connector for server backplanes is the Min SAS HD SFF-8643 internal connector. This connector has eight signal pins to support four SAS/SATA drives and six pins for the SGPIO (Serial General Purpose Input/Output) side-band signals. The SGPIO bus is used for efficient fault/activity LED management and sensing drive locate status. See SFF 8485 for the specification of the SGPIO bus. For backplane without enclosure SGPIO support, please refer to section step 5-1. LED cables for fault/activity LED cable installation.

Step 5-1. Install and Re-check Fault LED Cable Connections (Optional)

Make sure that the proper failed drive channel information is displayed by the fault LEDs. An improper fault LED cable connection will tell the user to "Hot Swap" the wrong drive. This can result in removing the wrong disk (one that is functioning properly) from the controller. This can result in failure and loss of system data.

The following electronics schematic is the SAS expander logical of fault/activity header. The signal for each pin is cathode (-) side.

Note:

Cables for the individual drive LEDs may come with a drive cage, or you may need to purchase them.

The following diagram shows all LEDs, connectors and pin locations.

Figure 2-5, ARC-8028-24 Activity/Fault LED Connector

Connect the cables for the drive activity LEDs and fault LEDs between the backplane of the cage and the respective connector on the ARC-8028 expander box header. The following table describes the activity/fault LED behavior.

LED Normal Status Problem Indication
Activity LED	1. When the activity LED is lit, there is I/O activity on that disk drive.2. When the LED is dark, there is no activity on that disk drive.	N/A
Fault LED 1.	When the fault LED is lit, there is no disk present.2. When the fault LED is off, that disk is present and status is normal.Some controllers support the "Identify Drive" function.When the "Identify Drive" is selected, the selected drive fault LED will blank.	1. When the fault LED is blinking (2 times/sec), that indicate disk drive has failed and should be hot-swapped immediately.2. When the activity LED is lit and fault LED is blinking (10 times/sec) that indicates there is rebuilding activity on the disk drive.

Step 6. Connecting SFF-8643 Cable to Backplane

The ARC-8028 expander box supports 6/8 Mini SAS HD SFF-8643 connectors on the back side. User uses suitable cable (depends on the backplane) to connect the expander box connector to the enclosure backplane.

Step 7. Setting Up the Dual Expander Mode (Optional)

If you don't want to support dual expander mode, you can skip this step to step 8. To set up the dual function of the expanders, you must perform the following hardware step:

- Connecting the Heartbeat Bus

Connect the 7-pin cable to the dual expander J3 header (2 x 4 2.54mm) of the primary and secondary expanders. The following picture is the signal name for heartbeat J3 header.

- Adjust the Micro Dip-switch

SW1(4) & SW2(1) micro dip-switch are used to enable or disable the dual expander relative function.

SW1 (4) DUAL CONTROL
ON ENABLE
OFF DISABLE

SW2 (1) MASTER/SLAVE
ON SLAVE
OFF MASTER

Step 8. Install the Enclosure Top Cover

Check the installation thoroughly, reinstall the enclosure cover, and reconnect the power cord cables.

Step 9. Loading Drive to the Drive Tray

You can connect the SAS/SATA drives to the controller through direct cable and backplane solutions. In the direct connection, SAS/SATA drives are directly connected to SAS PHY port with SAS/SATA cables. The SAS expander module can support up to 12/16/24/32 PHY internal ports and 12/16 PHY external ports. Remove the front

bezel from the computer chassis and install the cages or SAS/SATA drives in the computer chassis. Loading drives to the drive tray if cages are installed. Be sure that the power is connected to the individual drives or cage.

In the backplane solution, SAS/SATA drives are directly connected to SAS system backplane. The number of SAS/SATA drives is limited to the number of slots available on the backplane. Your ARC-8028 expander box supports up to 12/16/24/32 12Gb/s SAS or SATA 6Gb/s drives, each one contained in its individual drive carrier. Each drive is hot-pluggable, allowing you to remove and insert drives without shutting down your ARC-8028 expander enclosure. Install the drives to 12-bays ARC-8028 expander enclosure as shown in figure 2-6.

Figure 2-6, Install Drive into Enclosure

Step 10. Connect to Host Interface

Once the ARC-8028 expander box has finished the configuration (optional), then you can connect it to a host interface. The enclosure can be connected to a host interface which may a host adapter or RAID controller through the Min SAS HD SFF-8644 SAS cable. By installing host adapter port and ARC-8028 expander box using the correct external cables which may be included in your enclosure kits.

Step 11. Connecting Expander Box's RS-232 Port (Optional)

The ARC-8028 expander box's system functions can be managed via a PC running a VT-100 terminal emulation program, or a VT-

100 compatible terminal. The provided internal cable converts the RS-232C signals from the RJ11 into the one 9-pin D-Sub male connector.

Step 12. Add More Expander Boxes (Optional)

ARC-8028 expander box can run in one of two modes:

1. Normal Mode
2. Zone Mode

You must select either mode using the CLI utility and restart the ARC-8028 expander enclosure again. The manufacture is default on the Normal Mode. Changing the mode while the ARC-8028 expander box is on. This will not affect expander operation until the ARC-8028 expander enclosure is rebooted.

1. In normal mode

A SAS host can communicate with up to 24/32 drives in the 24/32 bay enclosure via a single ARC-8028 expander box. ARC-8028 SAS expander box is a device that contain expander ports. Expander ports may support being attached to SAS initiator ports, SAS and/or SATA target ports, and to other expander ports. The SAS RAID controller or host adapter can support daisy-chain how many enclosures which depend on the RAID controller or the host adapter firmware. The following figure shows how to connect the external Min SAS HD cable from the SAS RAID controller that has external ports to the ARC-8028 expander box enclosures.

Figure 2-7, Daisy-chain SAS Expander

2. In zone mode

The SAS expander box can be split into up to 8 virtual groups. Each group drive channels and external cable connectors are assigned by CLI GROUP command. The following figure is shown the SAS expander box which has split into 2 virtual groups. Each group drive channels are controlled by individual host adapter using SAS CH1 and SAS CH2.

Note:

1. Please refer to chapter 4.3 CLI features of GROUP command which is used to associate the external port and the devices/phys slot.
2. Turn on the expander enclosure first to make sure the SAS RAID controller or SAS host adapter recognizes the drives in the enclosure.

Step 13. Connect the Enclosure Power

4. CLI Manager

This Command Line Interface (CLI) is provided for you to manage the ARC-8028 series 12/16/24/32 SAS expander system functions. The CLI is useful in environments where a graphical user interface (GUI) is not available.

- Locations of RS-232C Port

The ARC-8028 expander box uses the RJ11 port as the serial port interface. Please use the cable included in the shipping box to configure the expander controller.

- Establishing the Connection for the RS-232 Port

The CLI function can be done by using an ANSI/VT-100 compatible terminal emulation program. You must complete the appropriate installation procedure before proceeding with the CLI function. Whichever terminal emulation program is used must support the 1K XMODEM file transfer protocol.

The serial port on the ARC-8028 box's I/O shield can be used in VT100 mode. The provided interface cable converts the RS232 signal of the RJ11 connector on the SAS expander controller into a 9-pin D-Sub male connector. The firmware-based terminal SAS expander management interface can access the expander through this RS-232 port. You can attach a VT-100 compatible terminal or a PC running a VT-100 terminal emulation program to the serial port for accessing the text-based setup menu.

4.1 RS-232C Port Pin Assignment

To ensure proper communications between the SAS expander box and the VT-100 Terminal Emulation, Please configure the VT100 Terminal Emulation settings to the values shown below:

Terminal requirement
Connection Null-modem cable
Baud Rate 115,200
Data bits 8
Stop 1
Flow Control None

The controller RJ11 connector pin assignments are defined as below.

Pin Assignment
Pin D	Definition Pin Definition
1 RTS (RS232) 4 GND
2 RXD (RS232) 5 GND
3	TXD (RS232) 6 GND

4.2 Start-up VT100 Screen

By connecting a VT100 compatible terminal, or a PC operating in an equivalent terminal emulation mode, all CLI administration functions can be exercised from the VT100 terminal.

There are a wide variety of Terminal Emulation packages, but for the most part they should be very similar. The following setup procedure is an example Setup VT100 Terminal in Windows XP system using Hyper Terminal use Version 3.0 or higher.

Step 1. Open the "Taskbar Start"/"Programs"/"Accessories"/"Communications"/"Heyper Terminal". (Heyper Terminal requires version 3.0 or higher).

Step 2. Open "HYPERTRM.EXE".

Step 3. Enter a name you prefer and then click "OK".

Step 4. Select an appropriate connecting port and then click "OK".

Step 5. Configure the port parameter settings and then click "OK". Bits per second: 115200

Data bits: 8

Parity: None

Stop bits: 1

Flow control: None

Step 6. Open the file menu and select "Properties".

Step 7. Configure the "Connect To" setting.

Step 8. Configure the "Settings" items and then click "OK".

Lowest SpeedCode: 3

Warning SpeedCode: 7

Fan internal command for different fan speed type:

fan -t [high | normal | low | vlow]

high : 6000 - 10000 rpm

normal : 1800 - 7000 rpm

low : 1000 - 2000 rpm

vlow : below 1000 rpm

The above is a rough value, user can set different to fit the fan speed type.

Default is normal.

- SPIN Command

The spin command defines the mode of staggering SATA drive spin-up function connected on the expander box. This command gives expander box the ability to spin up the disk drives sequentially or in groups, allowing the drives to come ready at the opti-

mum time without straining the system power supply. Staggering drive spin-up in a multiple drive environment also avoids the extra cost of a power supply designed to meet short-term startup power demand as well as:

Syntax

CLI>spin [Delay(D)[ms] Num(D)]

Expander issues the spin up the drives by [Num] drives with [Delay] ms.

Example:

CLI>spin

Current SpinUp Attribute:

Drive Number: 1

Delay: 1024 ms

CLI>spin 512 3

New SpinUp Attribute:

Drive Number: 3

Delay: 512 ms

Current SpinUp Attribute:

Drive Number: 1

Delay: 1024 ms

- ST Command

The st command stores system configurations or factory default configurations in flash. Since all the revised parameter setting is temporarily stored in the working RAM, the ST command saves those parameters permanently in flash ROM.

1. Store temporarily configurations in flash

Syntax

CLI>st

Example:

CLI>st

2. Store factory default configurations in flash

Syntax

CLI>st [default]

Example:

CLI>st default ;;; restore the setting to default

- FDL Command

The box has added the expander firmware update through the CLI on the external RS-232 port. Before you process the firmware update, there are two block regions that you can update expander microcode on SAS expander box.

1. CODE region - for FW file : sas3xfwYYMMDD.fw
2. MFGB region - for Data file : mfg12gYYMMDD.dat

To update the expander controller firmware, follow the procedure below:

Syntax: all the commands please type in lower case

CLI>fdl { code | mfgb }

Then use XModem/(Checksum) protocol transmit file to update ROM Region. The following procedures is used to update firmware through the RS-232:

1. Open any UART communication tools like HypeTerminal(115200,n,8,1).
2. Press any key on HyperTerminal window, the window will show "CLI>" prompt.
3. Type help will show help screen.
4. One command to update firmware. Step as follow.

5. Issue download & update command under "CLI>"; CLI>fdl code Please Use XModem Protocol for File Transmission. Use Q or q to quit Download before starting XModem. <----expander prompt for ready to receive file to update.

6. Then under HyperTerminal program, use the pull down menu item transfer "Send" -> send files when dialog box prompt, choose "Xmodem" and the file in the directory then press "send".

(a). If the expander receive the file under the timeout limit (60s), the process starts.
(b). If time out, please retry the step 5 again.

1. You can also cancel the program step by type 'q'.

2. If transfer OK, the transferred data is updated. Cold-start expander (Power cycle again) to take effect.

Example:

Update procedure, use Xmodem to transfer, refer to "fdl" command for detail operation.

CLI>fdl { code | mfgb }

Use HyperTerminal or TeraTerm utility with Xmodem mode to transfer and update files.

If transfer OK, the transferred data is updated. Cold-start expander (Power cycle again) to take effect.

The following firmware and data are available in the following filename format.

1. FW file (CODE) : sas3xfwYYMMDD.fw

2. Data file (MFGB) : mfg12gYYMMDD.dat

Update SAS expander firmware:

CLI>fdI code

Use HyperTerminal or TeraTerm utility with Xmodem mode to transfer sas3xfwYYMMDD.fw.

If transfer OK, the transferred data is updated. Cold-start expander (Power cycle again) to take effect.

Update SAS expander data file:

CLI>fdl mfgb

Use HyperTerminal or TeraTerm utility with Xmodem mode to transfer mfg12gYYMMDD.dat.

If transfer OK, the transferred data is updated. Cold-start expander (Power cycle again) to take effect.
