1Introduction

The Quantum TC2201 iSCSI router provides bi-directional connectivity between two iSCSI networks, and two Narrow/ Wide Fast/Ultra160 LVD/SE SCSI buses.
Supported devices include:
• Initiator Devices – iSCSI hosts
• Direct Access Devices – RAID controllers, Disk drives, JBODs
• Sequential Access Devices – Tape drives
• Changer Devices – Tape and Magneto-Optical libraries

SCSI buses
The SCSI and iSCSI interfaces are found on the front panel. Also on the front panel, Ethernet and Serial ports provide connections for configuration and management of the unit. The LEDs (operation indicators) provide basic status information.
Operation Indicators 1
The TC2201 is equipped with LED indicators for monitoring overall unit status (see

Chapter 1 Introduction

How the TC2201 Works

Power and Fault (Pwr)—This bi-color LED is green to show that power is currently active and is continuously amber-colored to show that the TC2201 detects a fault condition in the TC2201.
iSCSI (Link/Act)—When lit green, the right indicator signifies a good iSCSI link on the port. When lit green, the left indicator signifies iSCSI port activity.
SCSI Bus (0, 1)—When lit, these green indicators signify SCSI activity on the bus corresponding to the number of the indicator.
Ethernet (Link/Act)—When lit green, the right indicator signifies a good Ethernet link on this management port. When lit green, the left indicator signifies Ethernet port activity on this management port.
How the TC2201 Works 1
The TC2201 is a router that translates the iSCSI protocol to and from the SCSI Protocol—transparently transferring commands, data, and status information—so that devices and hosts can communicate with each other. Interconnection is provided between two SCSI buses and one or two iSCSI networks, also making use of iSCSI’s ability to encapsulate SCSI protocol packets.

Processing SCSI Information 1

The following section describes how the TC2201 processes SCSI information when attached to iSCSI hosts. through 5 of the process.
1 An iSCSI host issues a command. The iSCSI host encapsulates the
command in the iSCSI protocol and sends the packet to the TC2201.
2 The iSCSI controller in the TC2201 receives the packet, interprets the
iSCSI information, and places the packet in buffer memory.
3 The TC2201’s processor interprets the information and programs a
SCSI controller to process the transaction.

Chapter 1 Introduction

TC2201 Benefits

TC2201 Benefits 1
The Quantum TC2201 is designed to connect SCSI devices into an iSCSI network. The Quantum TC2201 is neatly packaged in a 1U form factor with two 1 Gb/s iSCSI ports and two LVD/SE SCSI buses. SCSI buses automatically negotiate for Fast, Narrow, Wide, and up to Ultra160 SCSI. External throughput is up to 200 MB/s bi-directional per iSCSI port (or 100 MB/s one way per iSCSI port), or up to a total of 400 MB/s bi-directional for both ports.

Enterprise Class Performance

SAN Management Reduction

Add Intelligence to SCSI Storage

The TC2201 offers enterprise class performance with memory buffer bandwidth exceeding 1 Gb/s and delivering end-to-end throughput of
1
up to 400 MB/s bi-directional for both ports (or 200 MB/s each way for both ports together). The TC2201 performs fast tape reads and writes, which enables it to handle larger data sets while completing backup and restore tasks within a smaller time frame.
The Quantum TC2201 is significantly easier to install than other routers due to the “store-and-forward” configuration feature and the Visual
1
Manager (VM) software. “Store-and-forward” allows configuration files and TC2201 operational settings to be saved and copied to other like routers, reducing redundant setup tasks. Using VM, service professionals and end users can configure a TC2201 with simple “point and click” choices on a graphical representation of the TC2201.
The TC2201 has many features that provide intelligence to SCSI devices and help manage SAN configurations, performance and reliability. A
1
short list includes Visual Manager, dynamic storage allocation (i.e. map activation without reboot), SCSI target reset, custom mapping, and access controls (LUN masking and management). These features of the TC2201 provide customers with a high level of storage functionality for high performance backup and recovery, reliability, security and manageability in their nearline storage solutions.
