SANRAD V-Switch User Manual
Limited Warranty
SANRAD warrants to the CUSTOMER that the hardware in the V-Switch to
be delivered hereunder shall be free of defects in material and
workmanship under normal use and service for a period of twelve (12)
months following the date of shipment to the CUSTOMER.
If, during the warranty period, any component part of the equipment
becomes defective by reason of material or workmanship, and the
CUSTOMER immediately notifies SANRAD or SANRAD’s local agent of
such defect, SANRAD or SANRAD’s local agent shall have the option to
choose the appropriate corrective action: a) supply a replacement part, or b)
request return of equipment to its plant for repair, or c) perform necessary
repair at the equipment's location. In the event that SANRAD requests the
return of equipment, each party shall pay one-way shipping costs.
SANRAD shall be released from all obligations under its warranty in the
event that the V-Switch has been subjected to misuse, neglect, accident or
improper installation, or if repairs or modifications were made by persons
other than SANRAD's own authorized service personnel, unless such
repairs by others were made with the written consent of SANRAD.
The above warranty is in lieu of all other warranties, expressed or implied.
There are no warranties, which extend beyond the face hereof, including,
but not limited to, warranties of merchantability and fitness for a particular
purpose, and in no event shall SANRAD be liable for consequential
damages.
SANRAD shall not be liable to any person for any special or indirect
damages, including, but not limited to, lost profits from any cause
whatsoever arising from or in any way connected with the manufacture,
sale, handling, repair, maintenance or use of the V-Switch, and in no event
shall SANRAD's liability exceed the purchase price of the Product.
DISTRIBUTOR shall be responsible to its customers for any and all
warranties which it makes relating to the V-Switch and for ensuring that
replacements and other adjustments required in connection with the said
warranties are satisfactory.
Software components in the V-Switch are provided "as is" and without
warranty of any kind. SANRAD disclaims all warranties including the
implied warranties of merchantability and fitness for a particular purpose.

Regulatory Information
FCC-15 User Information
The V-Switch has been tested and found to comply with the limits of the
Class A digital device, pursuant to Part 15 of the FCC rules. These limits are
designed to provide reasonable protection against harmful interference
when the V Switch is operated in a commercial environment. The V Switch
generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful
interference to the radio communications. Operation of the V Switch in a
residential area is likely to cause harmful interference in which case the user
will be required to correct the interference at the user’s own expense.
Warning per EN 55022
The V-Switch is a Class A product. In a domestic environment, this product
may cause radio interference, in which case the user may be required to
take adequate measures.
SANRAD V-Switch User Manual
Safety Notices
Read and understand the following notices before installing the V-Switch.
The power plug must be accessible at all times because it serves as the main
disconnecting vehicle.
Unplug the V-Switch power cord before performing maintenance procedures.
The V-Switch contains two power supply units. To disconnect the V-Switch
completely, all power supply cords must be unplugged.
Do not touch the power supplies when their power cords are connected. Line
voltages are present within the power supplies when their cords are connected.
The safety cover is an integral part of this product. Do not operate the unit without
the safety cover firmly in place. Operating the unit without the cover in place will
invalidate the safety approvals and pose a risk of fire and electrical hazards.
Blank faceplates and cover panels serve three important functions: they prevent
exposure to hazardous voltages and currents inside the chassis; they contain
electromagnetic interference (EMI) shields that might disrupt other equipment; and
they direct flow of cooling air through the chassis. Do not operate the system
unless all cards and faceplates are in place.
This product relies on the building’s wiring for short-circuit (overcurrent) protection.
Ensure that a fuse or circuit breaker no larger than 120 VAC, 15a U.S. (240 VAC, 10A
international) is used on the phase conductors (all current-carrying conductors).
The V-Switch is intended to be grounded. Ensure that the V-Switch is connected to
earth ground during normal use.
When installing the V-Switch, the ground connection must always be connected first
and disconnected last.
There is a danger of explosion if the motherboard battery is replaced incorrectly.
Replace the battery with the same or an equivalent type as recommended by the
manufacturer. Dispose of the used battery according to the manufacturer’s
instructions.

MANUAL
ORGANIZATION
CLI - COMMAND LINE
INTERFACE
The V-Switch is a storage virtualization and management solution
that allows you to pool physical storage resources and re-partition
the total storage capacity into virtual volumes that best meet your
storage needs.
The V-Switch is a high performance appliance that operates in the
data-path of a storage network between the hosts and storage subsystem. It provides a single, easy-to-use connectivity and
management platform for administration of small to Enterprise
class storage resources.

TECHNICAL
ASSISTANCE
Chapter 1: V-Switch
The V-Switch enables a network administrator to create and
manage virtual storage volumes using SANRAD’s Volume
Manager. The Volume Manager supports the creation and
combination of concatenated, striped (RAID 0) and mirrored (RAID
1) volumes.
The Volume Manager provides for secure exposure of virtual
volumes to hosts using the standards-based iSCSI TCP/IP-based
protocol.
15
V-Switch Overview
The V-Switch provides protocol bridging, routing, switching and volume
management in a single platform.
Figure 1, page 17, details a standard V-Switch network topology. Two VSwitches sit in the center of the network, providing load balancing and
failover ability.
Above the V-Switches are IP clouds connecting the network(s) management
and host stations. The hosts can connect to the V-Switch directly or via an
IP cloud. An iSCSI initiator agent in the host allows access to virtual
volumes in the V Switch.
Below the V-Switches are the network storage devices, which include both
JBOD (Just a Bunch Of Disks) and RAID subsystems. The V-Switch
provides the ability to connect via both SCSI and FC protocols, including FC
clouds, increasing the number of potential attached storage devices.
The V-Switch can be used in two modes:
iSCSI bridging switch
Storage virtualization switch
End-to-end Fibre Channel protocol networks are expensive to implement.
As an iSCSI bridging switch, the V-Switch acts as a protocol bridge between
storage devices on a Fibre Channel network and hosts on a standard IP
network.
The V-Switch also acts as a protocol bridge between SCSI storage devices
and hosts on a standard IP network.
Simple exposure of each storage device as a single LUN is an inefficient use
of storage resources. As a storage virtualization switch, the V-Switch
enables barrier-independent storage pooling with precise LUN carving of
new virtual volumes which support mirroring and striping with managed
exposure.

CLI - Command Line Interface
The Command Line Interface (CLI) is used to implement all V-Switch
management functions, including switching, virtualization and security.
The CLI is available via:
Console port via an RS232 connection.
10/100 Ethernet Management port via a Telnet session (V-Switch
3000 only).
1 Gb Ethernet port Eth1 via a Telnet session.
All CLI commands are case sensitive and must be entered in lower case.
Inputted data can include upper case letters but must always subsequently
be entered in the same case.
The CLI command prompt is >.
All CLI commands in this manual are listed first with the basic command
followed by a table of command switches; their explanations; status
(mandatory or optional) and an example for each command switch, as
shown in Table 2.
