1.2. Terminology
In this section, we introduce the terms that are used for the storage system throughout this
manual.
RAID
RAID is the abbreviation of Redundant Array of Independent Disks. There are different RAID
levels with different degrees of data protection, data availability, and performance to the host
environment.
Pools
A storage pool is a collection of disk drives. One pool consists of a set of volumes and owns one
RAID level attribute.
Volumes
Each pool can be divided into several volumes. The volumes from one pool have the same RAID
level, but may have different volume capacity.
LUN
A LUN (Logical Unit Number) is a unique identifier for designating an individual or collection of
physical or virtual storage devices that execute I/O commands with a host computer, as defined
by the SCSI (Small Computer System Interface) standard.
iSCSI

iSCSI (Internet SCSI) is a protocol which encapsulates SCSI (Small Computer System Interface)
commands and data in TCP/IP packets for linking storage devices with servers over common IP
infrastructures.
Fibre Channel
Fibre channel is an extremely fast system interface. It was initially developed for use primarily
in the supercomputing field, but has become the standard connection type for storage area
networks (SAN) in enterprise storage.
SAS
Serial-attached SCSI offers advantages over older parallel technologies. The cables are thinner,
and the connectors are less bulky. Serial data transfer allows the use of longer cables than
parallel data connections.
SSD
An SSD (Solid-State Drive) is a solid-state storage device that uses integrated circuit assemblies
as memory to store data persistently.
Thick Provisioning
Thick provisioning is allocated upon creation the physical disk drive space and is equal to the
user capacity seen by the host server. It also called fat provisioning.
Thin Provisioning
Thin provisioning is allocated on-demand and can be less than the user capacity seen by the
host server. It involves using virtualization technology to give the appearance of having more
physical resources than are actually available.
Snapshot
A volume snapshot is the state of a system at a particular point in time.
Local Clone
Local clone function has another physical data copy as the original volume.

Remote Replication
Remote replication function prevents primary site failure by replicating data to the remote sites.
QoS (Quality of Service)
QoS has a control mechanism that provides different priorities to ensure that the performance
of the data stream reaches a certain level according to the requirements of the application

2. GETTING STARTED
This chapter explains how to discover the storage system and how to sign into XEVO.
2.1. Discover the Storage System
The default setting for the management IP address is DHCP. For users who are going to install at
the first time, we provide the XFinder Java utility to search for QSAN products on the network
and aid quick access to the login page of the XEVO web interface.
2.1.1. XFinder Utility
XFinder utility provides to search QSAN products on LAN. You can discover the management IP
addresses of the storage systems via this utility. Please download XFinder utility from the
following website.
https://www.qsan.com/download.php
In addition, XFinder is a java based program. It is also a highly portable utility. To execute this
program, JRE (Java Runtime Environment) is required. You can visit the following websites to
download and install JRE.
http://www.java.com/en/download/
After JRE is installed, run the XFinder.jar program. The AFA storage system in your network will
be detected and listed in the table.

Figure 2-1 XFinder Utility
Take an example in Figure 2-1, XFinder discovers two systems in LAN. The default setting of the
management port IP address is gotten from the DHCP server, e.g., 192.168.30.242. The default
system name is the model name plus the last 6 digits of the serial number, e.g., XF2026-D60000.
Double-clicking the selected entry will automatically bring up the browser and display the login
page.
INFORMATION
XFinder utility works in the following network environments:
Both the management port of the SAN storage system and the
management computer are both on the same subnet domain of the LAN.
The LAN works with or without DHCP server.
If the LAN doesn’t have a DHCP server, it still can work on zero-
configuration networking. The management port will be assigned a fix IP
address: 169.254.1.234/16. So you can configure the IP address of your
management computer to the same subnet domain of the storage
system, e.g.: 169.254.1.1/16. Then open a browser and enter
http://169.254.1.234 to go into the login page. For more information
about zero configuration, please refer to:

The XEVO Web UI contains the following tabs:
Dashboard
The Dashboard function tab represents a graphical overview of the array, including hardware
alert, array capacity, system alerts, storage overview, and I/O (Input/Output) performance
metrics. For more information, please refer to chapter 4.1, Dashboard Overview section.
