1 ATTO iPBridge 2700 provides storage options

The ATTO iPBridge
TM
2700C/R/D iSCSI to Fibre Channel bridge offers an affordable opportunity to transform Fibre Channel storage into network-enabled addressable devices, creating scalable solutions for an iSCSI SAN.
The iSCSI protocol allows storage devices such as hard drives, tape drives and libraries and CD jukeboxes to attach easily to Internet Protocol networks such as Gigabit Ethernet. The ATTO iPBridge supports the high throughput needs of streaming data transfers, optimizing performance and management using ATTO Technology intelligent Bridging Architecture™.
Gigabit Ethernet (GbE):
a transmission technology based on the Ethernet format and protocol used in local area networks (LANs), providing a data rate of 1 billion bits per second (one gigabit) as defined in the IEEE 802.3 standard.
The iSCSI protocol:
increases the capabilities and performance of storage data transmission by transmitting data over local area networks (LANs), wide area networks (WANs), or the Internet, providing location-independent data
The iSCSI protocol enables complete SAN solutions based on a Gigabit Ethernet network infrastructure. iSCSI is a logical SAN alternative to direct-attached storage where simplicity, flexibility and price/performance are critical. iSCSI encapsulates SCSI packets in TCP, then routes the packets using IP. Block-level storage data is transported over IP networks using SCSI commands. Data may be accessed from virtually anywhere that can be reached through the Internet, eliminating physical boundaries. iSCSI implements SANs cost-effectively and manages SANs using technologies that you already have and understand such as SCSI, IP, Ethernet and SNMP, allowing you to take advantage of these interoperability benefits. iSCSI also lowers the investment cost of adding new servers to a SAN for both primary storage and backup applications.
storage and retrieval to enhance current and future Storage Area Networks (SANs).

2 Configuring the iPBridge

Set up your iPBridge by first getting an IP address, then use ATTO ExpressNAV to map devices. Default values are appropriate for most other configurations, but may be modified for your needs using ATTO ExpressNAV.
Configuration of the ATTO iPBridge, also known as iPBridge Services, is available through the ATTO ExpressNAV, a browser-based interface, or the Command Line Interface (CLI). ATTO iPBridge Services configures and tunes the iPBridge for many different environments and applications, updates the firmware, configures the addresses of the connected devices, monitors status and reports on hardware. To use the iPBridge, you must
1 Know the IP address for the iPBridge. (Refer to
Getting an IP address
2 Map devices so that the iPBridge can access
the devices in your network. (Refer to Target
management on page 11).
on page 10).
Additionally, it is best practice to change the default username and password and to set the Real Time Clock. Refer to
Additional configurations
on page 17.
CAUTIONCAUTION
Any changes must be saved and will not take effect until the iPBridge is restarted.
Note
The recommended management tool for the iPBridge is ATTO ExpressNAV. For details on the interface, refer to

2.1 Getting an IP address

Set up your iPBridge by first getting an IP address, then use ATTO ExpressNAV to map devices.
The iPBridge is set up by default to request an IP address from a DHCP server. If you do not have a DHCP server to assign IP addresses to devices, get an IP address from your network administrator. Use the QuickNAV utility from the CD included with your iPBridge to find your iPBridge on your network.
1 Work from the computer attached to the
iPBridge on the same broadcast domain. Find and download the QuickNAV utility,
QuickNAV-windows.exe, from the CD
included with your iPBridge.
2 Turn on the iPBridge.
Wait for the iPBridge Ready LED to light, up to three minutes, before proceeding.
3 Run the QuickNAV application.
a. Click Next on the QuickNAV Wizard
page.
b. Select your iPBridge serial number
from the list of choices displayed.
c. Click Next.
• If you are using DHCP, note the IP Address assigned by the server:
_________________________________
• If you are not using DHCP, configure the iPBridge with the IP Address and Subnet Mask given to you by your network administrator.
_________________________________

2.2 Target management

Devices are mapped using the designations for the iSCSI LUN. The easiest way to map devices is to use the Automatic Target Management feature in the ATTO ExpressNAV interface.
CAUTIONCAUTION
Changing the device map can affect the host’s view of devices and your application configuration
To map devices, you must have a host computer connected to the iPBridge Ethernet port. iSCSI target nodes are accessed through the Ethernet port, each identified by its own IP address.
You have two options to map devices.
1 You may use the default target node in which a
host or initiator will view the iPBridge as a single iSCSI node with all available devices shown as LUNs on a single iSCSI target.
2 You may map each device to its own target to
break the single iSCSI target node into multiple nodes. Multiple target nodes allow you to grant

Default target node

The default target starts with AccessControl disabled and CHAP authentication disabled. It cannot be deleted.
or deny access between initiators and devices as needed.

Target na mes

Each iSCSI target node accessed through the Ethernet port on an iPBridge is identified by its own IP address.
The iPBridge uses the
iqn
name format, referencing the device serial number, to guarantee that the target name is world-wide unique such as
iqn.1995-12.com.attotech:ipbridge: serialnumber
Note
Sample mapping pages are illustrated in Exhibit 2.2-2 and Exhibit 2.2-3.
If you are prompted to restart the iPBridge, go to the
Firmware Restart page and restart the
iPBridge.
Use the ExpressNAV interface to map devices automatically or manually. Refer to
ExpressNAV interface
on page 19 for
ATTO
information about ExpressNAV. Exhibit 2.2-2 shows the mapping page.

Multiple target nodes

Multiple targets allow you to create a more configurable mapping scheme which can segregate storage into different iSCSI nodes within the iPBridge, with each iSCSI target having its own set of access criteria.
For example, if you have two servers and a library with four tapes and a media changer, the default nodes would provide both servers access to all tapes and the media changer (default target mode).
If you configured multiple target nodes, you would be able to map some devices to one server and other devices to the other server, requiring separate usernames and passwords for access. Refer to Exhibit 2.2-1.
Note
If actual storage is mapped to more than one iSCSI target and a server has authorization for both targets, the server could show duplicate storage without any warning to the user.
You may use either of two methods to control access to storage: Access Control Lists or CHAP authentication.
Access Control lists:
each target iqn has its own access control. the iPBridge will check the initiator’s iqn before allowing access.
CHAP to control access:
different CHAP account names and CHAP secrets are assigned to each target. (Refer to
iSCSI commands
on page
51)
Refer to
ATTO ExpressNAV interface
on page
19 for information about ExpressNAV.

SNMP protocol

Remote system monitoring is available using Simple Network Management Protocol (SNMP). An agent resides in the iPBridge which takes information from the iPBridge and translates it into a form compatible with SNMP. If certain conditions arise, the agent sends asynchronous notifications (traps) to a client.
Refer to
Diagnostic commands
on page 43 for detailed information on the commands which regulate SNMP on the iPBridge.
Contact your network administrator for the MIB software and appropriate MIB file for your iPBridge. Use the
SNMP
page of the ExpressNAV interface to enable traps or extended traps.

Set up a VLAN: Virtual Local Area Network

A Virtual LAN (VLAN) is a group of devices on different physical LANs which can commu­nicate with each other as if they were all in the same physical LAN. This creates a network that is independent of physical location, allows grouping of users into logical workgroups, increases efficient use of resources, and adds security options by allowing some users into the LAN and keeping other users out.
Use the VLAN command to create up to eight Virtual LAN IDs for each Ethernet data port. Each VLAN ID is assigned a VLAN name of up to 64 characters. If no VLAN Id exists for a data port, VLAN is disabled for that port. For details on the command, refer to
Ethernet commands
on page

Check components

Use this procedure to check system components.

Checking Fibre Channel devices

1 Check Fibre Channel device power. Make sure
the devices are powering up.
2 Watch the drive lights before, during, and after
startup.
3 Check cable integrity. Check the cables for
solid connections.
4 If the problem persists, try drives one at a time
with different cables, adding drives and cables until the problem occurs. This helps pinpoint the drive or cable causing the problem.
5 Check with the manufacturer of the device(s)
for further troubleshooting methods.
If Fibre Channel devices appear to be working order, move on to the iPBridge Fibre Channel port section.

Checking the iPBridge FC ports

1 Either through the ATTO ExpressNAV or CLI,
check the devices on each port. Refer to Fibre
Channel configuration commands on page 48.
If no devices appear, re-check cables. If garbage information appears, the problem is most likely a bad cable.
2 Check the internal cabling of the device.
3 If all devices appear, invoke the
command several times on each port to verify
FCTargets
that the devices can be seen. If devices appear and disappear, then appear again, the problem is most likely a cable. For information on the
FCTargets command, refer to FCPortList on
page 48.
If all devices appear and remain, move to the iPBridge internal configuration section.
When changing any setting on the iPBridge, the configuration must be saved by clicking on the button on the ATTO ExpressNAV interface screen
or using the

6 If using DHCP (the default), verify that the
DHCP server is assigning the correct IP information to the host.
7 Verify VLAN IDs are either disabled or are set
up identically on the iPBridge and the connecting switch.
8 Some older switches/hosts cannot auto
negotiate between the iPBridge and the switch/host at the desired speed. You may have to force the host/switch or the iPBridge to the desired speed.
9 Verify that the host is logging into the iPBridge
correctly by viewing the and determining if there a “session open” status.

CLI command.
Checking the LAN/WAN
1 Verify that the switch/switches are segmented
properly so that hosts and the iPBridge have access to each other.
2 If there are routers involved in the setup, make
sure the IP addresses and/or MAC addresses of the iPBridge are allowed through the router.
3 Verify that the switch can see the iPBridge on
the port(s) in question. Refer to your switch vendor’s guide for more information.

Checking the iSCSI Host Adapter or NIC

iSCSI host adapters appear as a type of Storage Controller to the host OS, not as a standard NIC. These adapters usually have hardware acceleration to offload the TCP processing from the host. Configuration of these adapters is usually done through the vendor’s own utility and not through the OS itself.
NICs come in two types: accelerated and un­accelerated. Accelerated NICs use some hardware to offload some of the TCP processing from the host. Un­accelerated NICs make the OS do all TCP processing.
To check the iSCSI host adapter or NIC
1 Check cable integrity. Check the cables for
solid connections. Make sure they are plugged in properly. Inspect cable ends for broken clips and improper wiring.
2 Verify that the iSCSI host adapter or NIC is
configured with the correct IP information.
3 If using DHCP, verify that the DHCP server is
assigning the correct IP information to the host.
4 Verify that the hosts are running the
recommended driver and firmware level for the iSCSI host adapter or NIC vendor.
5 Verify that the hosts and the iPBridge are using
the same port number to communicate iSCSI. check the ATTO ExpressNAV iSCSI page. The default port number for the iPBridge is 3260.
6 Make sure the host adapter/NIC is configured
to log into the iPBridge. Some iSCSI host adapters do not re-login upon reboot or unplug/replug event without marking a check box.
28
Troubleshooting
7 Some older switches cannot autonegotiate
between the host and the switch properly. You could have to force the host or switch to the desired speed.
For a NIC using an OS iSCSI driver, continue to the iSCSI OS driver section.

Checking the iSCSI OS driver

If the host uses a driver that allows the OS to talk to iSCSI targets via a NIC, not an iSCSI storage adapter:
1 A PC using an iSCSI storage adapter and an
iSCSI OS driver might not work correctly on the same machine. Check with the vendors to make sure they are compatible.
2 Verify that the PC has the latest iSCSI driver as
well as the required service packs and patches. Check with the iSCSI OS driver vendor for more information.
3 Verify that the iSCSI OS driver has started.
Look under
lsmod for Linux.
4 Verify that the iSCSI OS is still looking for the
iPBridge at the right IP address.
5 If using DHCP, verify that the DHCP server is
assigning the correct IP information to the host. Refer to Getting an IP address
6 Verify that the NIC is configured with the correct
IP information.
Device Manager for Windows or
on page 10.
7 Verify that the hosts and the iPBridge are using
the same port number to communicate iSCSI on the ATTO ExpressNAV iSCSI page. The default port number for the iPBridge is 3260.
8 Check cable integrity. Check the cables for
solid connections. Make sure they are plugged in properly. Inspect cable ends for broken clips and improper wiring.

Checking the Operating System

1 Verify that the OS has the required service
packs or patches installed. If not, obtain the proper service packs and patches and install them.
2 Some iSCSI host adapters and iSCSI OS
drivers do not always automatically find new targets when plugged in or when forced to rescan. Reboot the hosts.
3 Check if the vendor has a new driver. If so,
install it.
Checking the Applications
1 Verify that the application is running the latest
device drivers for the devices connected to iPBridge. If not, get the latest device drivers and install them.
2 Verify with the application vendor if the iSCSI
technology is supported on the version of the application being used.

Performance Issues

If the host is not getting the performance it should, check the following items.

Checking Fibre Channel devices

Verify that the devices are running at their highest possible speed. Refer to

Checking the iPBridge Ethernet ports

1 Verify that the data ports are set to auto
negotiate or forced to 1000 Mbs on the ExpressNAV Ethernet page.
2 Verify that the MTU size is set to optimal setting
for the LAN/WAN environment.
Refer to Getting an IP address frame size is the current optimized frame size for the iPBridge. Smaller frame sizes causes a decrease in performance.
3 Verify that the iPBridge
disabled. Tracelog tracks certain events that

on page 10. 9k
occur in the iPBridge. With this log enabled, performance suffers.
Refer to TraceLog
on page 46.

Checking the LAN/WAN

1 Verify that the MTU size is set to optimal setting
for the LAN/WAN environment on the ATTO ExpressNAV Ethernet page.
9k frame size is the current optimized frame size for the iPBridge. Smaller frame sizes causes a decrease in performance. Many switch and router vendors do not support the larger frame size of 9k or 16k.
2 Verify that each associated port in the IP SAN
is configured for 1000Mbs.
IP SAN traffic should be segmented so that it does not interfere with the main LAN network traffic.For better performance, the IP SAN should be on its own set of hardware.
3 Verify that packets are not being dropped along
the LAN/WAN. Many utilities track packet activity and switch statistics.

Checking the Ethernet host adapter or NIC

Ethernet storage adapters generally outperform accelerated NICs and un-accelerated NICs by offloading most of the processing from the host.
An accelerated NIC provides some offloading, but still requires a host OS iSCSI driver, making the host spend more CPU cycles.
An un-accelerated NIC does not offload anything so the CPU must do much of the processing.
1 Verify that the adapter or NIC is sent to auto-
negotiate or forced to 1000 Mbs.
2 Set the MTU size to the largest MTU size
supported in the LAN/WAN using the Ethernet page in the ATTO ExpressNAV interface.
9k frame size is the current optimized frame size for the iPBridge. Smaller frame sizes cause a decrease in performance. Many switch and router vendors do not support the larger frame size of 9k or 16k.
3 Set the maximum transfer size to the most
efficient size for the intended target(s). For many tape drives, 64k is the optimal setting.

Checking applications

Some applications can be configured to change transfer sizes. Configure the application for the optimal size for the particular device(s) connected to the iPBridge.

Checking the host system

The faster the host, the faster your transfer times will be. The work flow goes only as fast as the slowest connection in the host system, so transferring data from an IDE drive, 100Mb connection, a DLT 4000, a high speed RAID volume across the country, or other
applications, slows the system no matter how fast everything else is in the system.
1 Verify that the iSCSI storage adapter or NIC is
connected to the fastest PCI bus connector supported by the adapter or NIC.
If the adapter supports PCI-X, place the adapter in a PCI-X slot. If one is not available, the host might not achieve the optimal performance capable from the adapter.
Even placing a PCI-X adapter into a 64 bit 66 MHz slot loses performance. Some adapters adjust clock speed depending on the speed of the PCI slot into which they are plugged.
2 The host OS disk and swap disk/partition/file
should be on a high speed drive to minimize the time needed to access the host’s virtual memory.
The more memory a system has, the less time it spends accessing virtual memory (hard drive space).

Checking the Operating System

If possible, eliminate swap space and virtual drives which require large amounts of system memory. However, the OS might not allow the elimination of swap space. An OS set to run many kinds of different servers spends much of its CPU cycles on other operations, thus slowing down performance.

6 Alternative interface options

Alternative methods to using the ATTO ExpressNAV interface may be used to manage the iPBridge. ATTO ExpressNAV is the recommended interface.

Use the serial port or header

1 Connect a cable from iPBridge RS-232 serial
port or header to the serial (COM) port on a personal computer.
2 Turn on the iPBridge.
3 Start a terminal emulation program on the
personal computer, and use it to connect to the iPBridge. For example, if you are using HyperTerminal on a computer running a Windows operating system,
a. Type iPBridge in the New Connection
dialog box.
b. Click OK. c. In the Connect To dialog box, for the
Connect using field select the COM
port number to which your serial cable is connected.
d. Click OK. e. In the COM Properties dialog box
select the following values:
• Bits per second: 115200
• Data Bits: 8
• Parity: None
• Stop Bits: 1
• Flow Control: None
• Terminal type: ASCII
• Echo: off
f. Click OK.
4 After you connect to the iPBridge, start-up
messages are displayed. These messages are only displayed at start-up. The last line in the start-up message sequence is example in Exhibit 5 on page 31.

• If a list of all available commands does not appear on the screen, review the steps in this section, check the cable, or contact service personnel until the problem is solved.
If you have difficulty using the serial port, verify that you have the correct settings and that your serial cable is less then two meters in length.

Use Telnet

Up to three Telnet sessions can be conducted simultaneously. A serial port session can use the CLI while Telnet sessions are open. Whichever session issues the first “set” CLI command can continue to issue set commands, while the other sessions can only issue “get” commands or display information. Once a connection is established, refer to

Appendix A Cabling

Additional information to physically connect ports to devices and to your SAN.

Fibre Channel connections

The Fibre Channel port connects the bridge into either a Fabric or Arbitrated Loop.
The iPBridge 2700 uses optical SFP connectors and multimode fiber optic cable.
Cable length Cable size
Up to 175 meters 62.5 micron
Up to 500 meters 50 micron
Make sure all cables are anchored securely at both ends with the proper connectors.

Ethernet connections

Use at least Cat 5e cable to connect the Ethernet ports to your network.
Note
For best performance, all cabling, network interface cards (NICs), host bus adapters (HBAs), and network switches must be Gigabit Ethernet (GbE), and at least Cat 5e certified. Most standard offices use 2-pair wiring which is not compatible. GbE requires 4-pair wiring.
For best performance, support for 9014 byte jumbo frames should be available for all switches and host iSCSI equipment.
Before you begin installing the iPBridge Ethernet ports, be sure to check or complete the following:
• If you are managing your iSCSI system across a WAN and your system uses a firewall, be sure that the following ports are open and available:
If you are using the TCP protocol
• telnet (port 23)
• http (port 80)
• ftp (ports 20 and 21)
• iSCSI (port 3260)
• iSNS (port 3705)
If you are using the UDP protocol
• ntp (port 123)
• Be sure your host system(s) is set up and configured.
• Your host system can use any of three different types of cards: a network interface card (NIC), a TCP/IP offload engine card (TOE), or a storage network interface card (SNIC).
• The ATTO driver file from the CD included with your iPBridge or from the ATTO website, www.attotech.com, is installed on your host.
• The switch has been configured to forward UDP broadcast messages.
• The minimum requirement for Windows-based browsers is Internet Explorer 5.5 or Netscape Navigator 6.2. The minimum requirement for Macintosh browsers is Internet Explorer 5.2 or Safari 1.2.
• Ethernet speed defaults to auto; the iPBridge will determine the speed and set other parameters based on the speed.
