1.3 Setting up the Hardware
1.3.1 Installing the HBA
Before the ExaSAN Compact Solution components are ready to be connected and powered on, you must install
one HBA in each workgroup client system. The HBA is compatible with PCIe x4, x8, and x16 slots. If a choice is
given, use the fastest PCIe slot available. Although the HBA is compatible with both PCIe 1.1 and 2.0 standards,
only PCIe 2.0 is recommended for best per formance.
P6
Follow these steps to install the card in each host system:
1. Hold the HBA wi th moun ting plate facing your lef t.
Locate the “mode” jumper switch on the north edge at
center-right, as shown and labeled below.
2. Thi s HBA card can be used both in DAS and SAN
app lic ati ons, whether or not the HBA car d was just
purchased or originally used in storage. In this case,
the HBA c ard is use d for connec ting the C ompac t
Switch. Please make sure the switch button is toward
the “1” position, as shown below.
3. Position the connector of the card over the slot, insert
the connector into the slot, press gently but rmly until
it is securely seated.
4. Secure the metal bracket of the card to the system
case with a screw.
5. Replace the outer casing cover.

6. Install the HBA device driver
a. Insert the Installation CD
b. Launch the Installation Package
c. Follow the on-screen instructions to complete the driver installation
1.3.2 Connecting the Switch to the RAID System
Use the procedures below to connect the SW08-Q4 Switch to the A12S2-PS RAID system.
Note: The top two rows of ports in the rear panel of the SW08- Q4 Switch has eight (8) QSFP ports available
for connectivity of up to eight clients. The bottom row of four (4) QSFP por ts are for connectivity of up to four
A12S2-PS RAID units.
1. Connect your RAID storage unit to the ExaSAN SW08-Q4 Switch with
an QSFP cable. Insert one end of the PCIe cable into the PCIe por t on
the back of the RAID system. Your cable connector is securely plugged
when you hear a "click". If you need to unplug the cable, pull the ring on
the connector rmly until it is detached from the port.
2. Insert the other end of the cable into one of the three storage module
ports on the rear panel of the ExaSAN switch.
3. Plug a power cord into the AC power-in port in the storage unit; do not
turn power on yet.
Warning:
Follow the power-on sequence shown in 1.4
Connecting to a Power Source and Powering ON.

User Guide
1.3.3 Connecting Switch to the Client System
1. Inser t one end of the QSFP cable into one of the client module ports on the rear panel of the switch. Your
cable connector is securely plugged when you hear a click. If you need to unplug the cable, pull the ring on the
connector rmly until it is detached from the port.
2. Insert the other end of the cable into the QSFP port on the HBA,
which you installed on the client system earlier in Section 1.3.1.
3. Repeat steps 1 and 2 for client systems #2.
4. Plug a power cord into the AC power-in por t on the rear panel of the
switch. Do not turn power on yet.
1.4 Connecting to a Power Source and Powering On
Before powering on, make sure that all cables and cords are properly installed and connected.
Caution:
Follow the power-on sequence shown bellow to prevent damage to system.
1. If not yet plugged into the wall electrical outlet, plug the power cord for the storage unit and the ExaSAN switch
to a power source.

2. Turn power on for the A12S2-PS RAID storage unit rst by pressing the Power
button. Access LCD will be blue to indicate A12S2-PS RAID storage unit is
powered-on.
3. Power on the ExaSAN switc h by pressing th e Powe r but ton. Wait for the
Heartbeat LED to turn into a steady ashing blue light. Note that you might
hear a few sho rt beeps gen erated fr om the swi tch durin g this pro ce ss.

2. Software Installation and Configuration
Now that we have connected all hardware components and turned on the power, follow the steps in this section to
set up ExaSAN and Sanit.
2.1 ExaSAN Setup & RAID GuardX RAID Configuration
(Please refer to the A12S2-PS RAID User Manual)
2.1.1 Switch GUI Setup
The ExaSAN sw itch has a brows er- ba se d buil t- in GUI (Graphi ca l User Interf ace) for admi nistrat io n and
conguration tasks.
2.1.2 Launch the Switch GUI
You may use either the FireFox or Safari browser to access
the switch GUI. We recommend that you use FireFox.
1. Launch the browser of your choice
2. Ma ke sure t h at our pr i va te Et her n et netwo r k is
connected
3. Go to IP address 192.168.0.1
4. The GUI’s home page displays
5. Log in with default user name “admin” and password
“0000”

2.1.3 Switch GUI Overview
We are now at the switch GUI main menu page. You may toggle between “Cong Mode” and “Monitor Mode” by
clicking the “Switch Mode” icon at the top. You may also go into “System Management” to change the switch IP and
password, or to set system date and time.

Note that before you perform any system administration function, you should set your system date and time rst.
2.1.4 Quick Setup
We will create two LUNs in the RAID disk system. One is for the Xsan metadata and the other for the user data.
1. Select “Quick Setup” from the menu options on the left pane to start the process

5. Click “Apply”
After you click the “Apply” button, the system will start the process of initializing the disks in your RAID storage
system. During this process, you may experience deterioration in overall system per formance, this is normal.
Please allow suf cient time and patience for this process. Upon completion, the LED indicators on the front panel
of your RAID system will ref lect that status. Refer to the appropriate documentation of your RAID system for
additional information.

User Guide
2.2 Verify Accessible LUNs
To view the two LUNs which we just created, open
th e M ac “S ystem Pr of iler ” and then ex pand the
“Parallel SCSI” tab. You should see that two ExaSAN
LUNs are visible as described below.
Find one LUN in “SCSI target Device @0,” another
LUN in “SCSI Target Device @1.” Both are identied
with Manufacturer “ACCUSYS” and Model “A12S2PS.”
Note that you will need to perform this check on all
computers in the SAN. If you do not see any LUN
here, you’d have to t roubl eshoot the connection
betwe e n th e E x a S A N R AI D sy ste m an d th e
SW08-Q4 switch.

3.1 SAN Management software Installation
SANit is a powerful SAN management software and le system specically designed for extremely reliable highperformance, cross platform and le-level shared access workows. Be sure your MDC eviormnment is all set up
already. Begin utilizing your SANit SAN management software by following the steps shown below.
Requirement stuff:
1. MDC server installed Cent OS 5.3 (2.6.18-128.el5)
2. SANit software
3. Licence
4. Ethernet
3.2 Connecting the Private LAN
In addition to the ExaSAN PCIe network, all computers for the SAN must be connected to a private Ethernet
network (the Private LAN). SANit MDC servers and clients use this network to exchange le system metadata.
Connect each SAN client and MDC server to two Ethernet networks: one private subnet for the SAN metadata and
a separate connection for directory service, intranet, and Internet trafc (the Public LAN).
The steps below apply to the Private LAN only. We assume that the Public LAN is already in place.
1. Connect your workgroup client system #1 to the private LAN Ethernet switch with a CAT-5 cable
(Lan switch hub).
2. Repeat Step 1 for client systems #2.
3. Connect the ExaSAN switch to the private LAN Ethernet switch with a CAT-5 cable
(For the monitor switch of the R AID Guard X conguration).
P20
User Guide
Client and metadata controller computers need static (xed) IP addresses for Ethernet network connections. Don’t
use DHCP to assign dynamic IP addresses to SANit devices. We suggest that you use the following ranges of IP
addresses for SANit private metadata net work:
• Subnet mask: 255.255.255.0
Software Installation le on MDC
The following is installation command
1. The le name is SANIT-5.3.3-450.x86_64.rpm (Example version)
#rpm –ivh SANIT-5.3.3- 450.x86_64.rpm
#sanit-setup
2. Uninstatall command
#sanit-unsetup
3.3 SANit Configuration
1. Enter your MDC* IP address in the URL of your computer and then
enter port number 85. See below:
http://[MDC IP address]: 85, for example, http://10.10.88.10:85.
