Case Study | Aligrup S.p.A.
Aligrup S.p.A. (a partner of SPAR International)
Major Food Retail Chain choose Allied Telesis for Network Expansion in Italy

Customer Profile
Aligrup S.p.A. creates and promotes high-quality distribution
systems predominantly geared towards meeting the demand
for food products and services.
Although Aligrup S.p.A. was officially founded in 1987,
Sebastiano Scuto,awholesale grain dealer, laid the foundations
for the company over a century ago. Since then, Aligrup S.p.A.
has played an increasing role in Sicily's economic
development.
This development culminated in the agreement signed
between Coop and Despar. They created a common
purchasing company called Centrale Italiana.The alliance will
help improve the distribution system and achieve economies
of scale in purchase management. Aligrup S.p.A. is generating
24% of their turnover.
The Customer Challenge
As Aligrup S.p.A. expanded, they needed a network that was
flexible and configured to handle the current and future needs
for a distributed system. Since the new Aligrup S.p.A. office
space in San Giovanni la Punta is large and modern, they
decided to lease part of it to turnkey contracts.They also
decided to offer the other companies infrastructure services,
including networking services.
This affected manyof the decisions about their network. In
addition to paying extra attention to security levels, they
wanted to segment the networkwithout sacrificing
performance and reliability, and to scale the network for
future needs.

PROFILE
Aligrup S.p.A., San Giovanni La Punta, Catania, Italy
Aligrup S.p.A.(San Giovanni La Punta), a major retailer representing Despar (SPAR International)
throughout most of Sicily, has been expanding in both physical space, reach and subsequently, its IT
network. Because of this, the food retailer needed a more secure and reliable system to meet their
needs, as well as the needs of several other companies who lease space from them in their new
location.Allied Telesis helped them develop a high-performing and more secure network solution by
providing multi-layer switches integrated with existing Allied Telesis devices.

Why Aligrup S.p.A. Selected Allied Telesis
The multi-layer switches from the Allied Telesis 9900 series
immediately proved to be ideal for supporting such a flexible
architecture. All the features that make it stand out, from its
Quality of Service (QoS) and high-density Gigabit Ethernet
ports to its non-blocking architecture and redundant power
supply units, provide a competitive advantage.
In addition, integrated support for IPv6 ensures that the
system will scale to increased use, protecting their technology
investment.
The 9900 series is particularly flexible because it can host
different types of SFP interfaces on the same platform. It
caters to any combination of copper and short-haul or long-
haul fiber links, which was required to overcome cabling
distance limitations in their large new building.
With the possibility of using traffic meters via the SNMP
management platform, Aligrup S.p.A. also has the option to
connect to billing tools in the future.These tools would be
able to charge their turnkey contract customers based on the
usage of the networkservices.
Aligrup S.p.A. decided to invest in the future by expanding
and improving their IT network.They chose to involve Allied
Telesis, an expert partner.
"We've especially appreciated the technical support provided
byAllied Telesis, whether directly or indirectly, throughout the
whole process of designing, deploying and supporting the
network," concluded Schilirò, who has closely monitored
everyphase spanning the project's design, integration and
execution.
Key Decision Factors
Aligrup S.p.A. chose a technical solution from Allied Telesis for
many reasons; however, they had four primary ones. Reliability,
scalability, security and support.
Reliability: The redundancy protocols, bandwidth
management options and power supply units' redundancy
make the network resilient.This helps the network services to
achieve maximum reliability and uptime of critical services,
required not only for operational functionality of Aligrup
S.p.A., but also for it’s turnkey contract customers.
Instead of taking up extra space in the cabinet, the redundant
power supply unit is integrated into the switch.This compact
design does not compromise performance, since the
enhanced horizontal cooling system makes it possible to
withstand high temperatures.
The high performance level and extended QoS and
management functions help give precise network control.
Scalability: The cutting-edge switching technology supports
connections ranging from 10Mbps to 10 Gigabit Ethernet.The
modular design of the core machines (AT-9924Ts,
AT-9924SP), along with the wide selection of uplinks for the
switches designed for distribution (AT-9748TS/XP and
AT-8648T/2SP) provide even greater scalability for future
needs.
Security: The management security options (SSH and SSL),
authentication protocols, hardware filters and switch port
control cover every aspect of network security. In addition,
the advanced
VLAN functionality will ensure complete
separation of the different companies networks, while allowing
Aligrup S.p.A. to easily manage and maintain the network
infrastructure.
Support: Aligrup S.p.A. valued the technical support they
received from Allied T
elesis. Net.Cover®is a comprehensive
service and support program designed to protect vital
networksystems from unscheduled downtime.This
comprehensiveservice includes phone support, priority
queuing, and next day product replacement.

"Aligrup S.p.A. is extremely happy with the quality and
performance of the Allied Telesis equipment,"
confirmed Daniele Schilirò, who is responsible for
networking and new technologies at Aligrup S.p.A.

Technical Overview
To achieve the level of expansion they required, Aligrup S.p.A.
used several Allied Telesis multi-layer switches.
n 9900 Series – Gigabit Multi-layer Core Switches
n 9700 Series – Gigabit Multi-layer Edge Switches
n 8600 Series – Fast Ethernet Multi-layer Edge Switches
The switches in the 9700 and 8600 series are designed for
enterprise applications.They are ideally suited as the primary
solution in the aggregation and distribution tiers of large
networks, or for server farm and data center aggregation.
The 9700 series includes a variety of 10/100/1000 Layer 3
stackable switches featuring 10G uplinks, capable of supporting
anything from a few dozen to 1,500 users. This series is
distinguished from similar devices on the market byits high
performance 40Gbps switching backplane speed and 10G
uplinks.
In addition, the main competitive benefits are scalability,
security, and reliability – down to the stacking ring architecture.
The price to performance ratio delivers excellent return on
investment.
The 8600 series switches, feature 10/100TX Fast Ethernet
copper ports with a choice of copper and fiber Gigabit
Ethernet uplinks. These have been designed to support
aggregation and access applications, but their wealth of
functions makes them ideal for use as a backbone in small
networks.They are used in the Aligrup S.p.A. network as
access machines for connecting users.
Every switch in the 8600 series is connected to the
distribution cabinet via high-speed Gigabit links. All the Layer 3
options in AlliedWare™, the firmware installed in Allied Telesis
multi-layer machines, are deployed in these switches.The
firmware supports advanced security management and QoS,
and refined user profiling.

SERVER FARM
Aligrup S.p.A. Network

The backbone of the network is based on the 9900 series of
core high-performance switches, which are used to
interconnect all the distribution and access switches to the
server farm using both copper and fiber cabling.
The design of the network can be divided into three distinct
parts, labeled CORE#1, CORE#2 and SERVER FARM.The
network is based on a star topology, with the AT-9924Ts
switch being at the center of the network.This switch
provides all of the core routing functionality in the network.
Both the CORE#1 and SERVER FARM sites are connected
using 10 Gbit fiber optic links that terminate at the central
AT-9924Ts switch.The local MARKETING and
ADMINISTRATION groups are connected to the
AT-9748TS/XP distribution switch which is located at
CORE#2 which in turn connects to the central
AT-9924Ts switch via a copper uplink.
The network is based on two virtual LANs.The first one
(default) is intended for network users, while the second one
is dedicated to network devices and servers.
All the switches can be managed by the network
administrator from either VLAN. However, to simplify the
networkconfiguration, and to reduce the waste of IP
addresses by implementing both the VLANs on all the
switches, static routes have been deployed.
The SNMP protocol has been activated on all the devices for
management support, and an ‘aligrup’ community has been
defined for managing the devices via SNMP, which has
read/write access to all the configurations.
We assigned the functions of manager and trap host (for
managing alarms and faults) to a workstation on which the
management platform was installed.This was designed to
improve the monitoring of the entire network.
All the switches used in the Aligrup S.p.A. network also come
with a Net.Cover®service and supportcontract as standard,
as do all Allied Telesis Layer 2+ managed devices.This means
that the device can be replaced by the next working day in
the event of a fault.
