Overview

The hardware infrastructure is designed to supply both bioinformatics and IT services. The main hardware components are located in a dedicated room, able to guarantee continuous mains power and controlled air temperature, allowing full reliability of the installed devices.


Servers

The central system includes a series of servers of different power class:

  • Main servers: 2 IBM servers with 8 processors, based on Intel IA32 bits architecture, dedicated to the management of large databases and programs used into the bioinformatic research activities. Their specifications are:
8 Intel PIII XEON 700 Mhz
4 Gb of RAM
SCSI internal disks;
external SCSI disk array DAS (Direct Attached Storage);
double ethernet interface configured for fault tolerance.
  • Biprocessor servers: 5 IBM biprocessor servers, based on Intel IA32 bits architecture, dedicated to the base IT and bionformatic services (mail, web, fileserver, vls). Their specifications are:
double Intel PIII 1Ghz;
1-2 GB of RAM;
SCSI internal disks;
external SCSI disk array DAS (Direct Attached Storage);
double ethernet interface configured for fault tolerance.
  • Cluster: 1 cluster server composed of 4 physical boxes containing 14 node servers each, for a total of 56 server nodes and dedicated to the High Performance Computing (HPC) activities. Each of the 56 node server is an independent computer with the following specifications:
double Intel P4 3Ghz with hyper-threading support;
2 Gb of RAM;
double EIDE internal disks;
double Gbit ethernet interface.
  • Other servers: 4 single processor servers, used to support activities and services such as monitoring and network management.
  • Mac server: 1 Apple PowerPC biprocessor, dedicated to the services for clients.


Clients

The clients, approximately 200, are subdivided between Apple Macintosh and Windows Pc. Apple clients mainly use PowerPC processor, but recently new models have been acquired that use the Intel Core Duo processor. Memory RAM, is typically between 512 MB and 1 GB, while the disk size is at least 80 GB. The operating system in use for all Apple computers is the MacOSX, versions 10.3 and 10.4.

Windows based PCs, mount Intel processor, generally Pentium IV, and some Pentium III. Memory RAM, is between 512 MB and 1 GB, while the disk size is at least 80 GB. The operating system is Microsoft Windows, versions 2000 and XP, but some client uses also other operating system like Linux.

To ensure the connectivity to the internet, all the clients can be configured with public or private IP addresses; in case of a public IP, the clients are available from outside to use services such as AFP, FTP, Samba, HTTP, etc. Every MsWindows client is supplied with antivirus software and a Firewall to ensure the necessary security and protection.


Network devices

The network infrastructure consists of one central layer 3 switch, acting as a router (Cisco 4006) and a number of switches Cisco 3500 series used to distribute the peripheral network. The connectivity to the Internet is guaranteed by a 2 Gbit fiber connection to the close Faculty of Medicine network. The CEINGE provides also a wireless connectivity service, through wireless access points (Cisco Aironet 1200 series) configured in one big infrastructure covering all the areas of the building, allowing internet access to all kind of mobile device.
