Introduction
This User’s Guide explains how to install and use the Chaparral™ VFS113 router. This
member of the Velocity family of routers is a Fibre Channel (FC)-to-Small Computer
System Interface (SCSI) router that enables connectivity between SCSI devices and
storage area networks (SANs). The router provides Fibre Channel connection to SCSI
devices allowing them to be attached to either a Fibre Channel Arbitrated Loop (FC-AL)
or switched fabric.
The router allows SCSI and Fibre Channel devices to communicate seamlessly by
converting data to the appropriate protocol and routing it to the desired destination.
The router supports a variety of SCSI devices including:
IHard disk drives
ITape drives
ITape libraries
IOptical devices and libraries
IRAID controllers
About This Guide
This User’s Guide describes how to install and configure your book title. It assumes that
you are familiar with the basic functions of your computer system. It also assumes that
you are familiar with Fibre Channel configurations and basic network administration
terminology.

The router is available in both low-voltage differential/single-ended (LVD/SE) and high-
voltage differential (HVD) SCSI models.
About Serverless Backup
Recent advances in data protection architectures have added the ability to back up data by
moving it directly from disk to tape without first passing through a backup server. This is
called serverless backup, and it utilizes a new SCSI command, Extended Copy (EC). A
host is involved in executing the EC command, though it is typically not the server. The
Chaparral family of Intelligent Storage Routers is enabled to execute the EC command
under the control of most major backup applications.
The EC command consists of three primary pieces of information:
ISource addresses
IDestination address
IIn-line data
The source addresses tell the router where the data that is being copied is physically
stored, on what device and at what physical locations. This information is provided by a
backup application, which must translate file information into the physical storage
locations. The application sends this list of addresses in the order it is to be written to the
destination device, often a tape drive in a backup scenario.
For the destination address, the EC command assumes that any tape device that is being
copied to is in the proper location, so all the router needs to know is its target address,
typically a LUN on the SAN. The in-line data is used to allow applications to maintain a
specific format, and can be used to write any data the application may require for
restoration.
Note: It is important to know which model you have and the associated
features. (See Specifications below.)

VFS113 Rack/Desktop Model User’s Guide
1-4
The EC command, as implemented in the Chaparral router, requires no administration.
Administering an EC environment is most intensive on the application side. Chaparral
supports the Storage Networking Industry Association Extended Copy Specification
(ANSI T10/ 99-143R1). Any questions related to using a Chaparral router in an EC
environment should be directed to the application provider or your reseller. If you are
developing EC enabled applications, contact Chaparral for information on our specific
implementation.

Installing the Router
This chapter provides step-by-step instructions for installing the router.
You must take many factors into consideration while planning the router installation. Due
to the versatility of the router and the diversity of available host platforms, host bus
adapters (HBAs), switches, hubs, storage devices, and applications, only general
guidelines are found in this Guide. For examples of the most common configurations, see
Installation Configuration Examples on page 2-4.
You can mount the router in a standard 19" rack or place it on a table or desktop. Be sure
the operating environment meets the requirements found in Specifications on page 1-4.
To install the router, you need to complete the following tasks in sequence:
1Unpack the router. See page 2-1.
2Install the router. See page 2-2
3Connect the router. See page 2-7.
4Power up all devices. See page 2-10.
Unpacking the Router
Carefully unpack the router and ensure that you have all the parts specified below:
IRouter
IFive rubber feet
IPower cable
IRS-232 cable
IUser’s Guide
IMounting brackets (with 4 Phillips screws that are already screwed into the side of the
router)
To unpack the router:
1Place the shipping container on a flat, clean, stable surface.
2Carefully remove the router and verify the contents against the packing list.
3Remove the foam from the sides of the router and remove it from the plastic bag.
Save the original shipping container and packing materials in case future reshipment
is necessary.

4Visually inspect the router and notify your freight carrier immediately of any
damage.
5Record the Media Access Control (MAC) address located on the label of the router
box for future reference.
Figure 2-1 below shows the front and rear panels of the VFS113.
Figure 2-1. VFS113 front and rear panels
Installing the Router
You can install the router two ways:
IOn a desktop or table
IIn a standard 1U high, 19" rack
Installing on a Desktop
To install the VFS113 on a desktop:
1Attach the five rubber feet to the recessed locations on the bottom of the router.
2Place the router on a table, desktop, or other flat surface.
Note: Ensure that the front and rear panels have adequate clearance for
the fan, air intake vents (front), and access to all connections.

Installing in a Rack
You can install the router in a standard 1U high, 19" rack. You can either front or rear
mount the router.
Parts required for this procedure (shown in Figure 2-2)
ILeft and right mounting brackets (only left bracket shown)
IFour mounting screws (10-32 panheads)
Figure 2-2. Mounting bracket and screws
Recommended tools for this procedure:
I#2 Phillips screwdriver
To install the router in a rack:
1Determine where in the rack you want to mount the router.
The mounting brackets are reversible, permitting either front or rear mounting.
2Remove the screws from the sides of the router and keep the screws.
3Using the screws you removed, attach the brackets to the router.
Be sure to place the front of the brackets at the front (for front mounting) or rear (for
rear mounting) of the router, depending on how you are mounting it in the rack.
You may have to squeeze the top and bottom of the router to align the holes.
4Install in the 19" rack according to the rack’s instructions.
Note: Ensure that the front and rear panels have adequate clearance for
the fan, air intake vents (front), and access to all connections. The proper
airflow is from the front of the router to the back.
