  • 1. Introduction

  • IntroductionInstead of CIT planning a Virtualisation project, CITs Infrastructure evolved from various small IT initiatives in the college.Now, it represents a sizeable virtualised infrastructure and our reliance and dependency on it has grown enormously.Administration, student services, IT services, academic departments all now depend on this infrastructure.

  • In the beginning .Cisco Academys Netlab System - introduced support for virtual PCs in the pods using VMWare GSX, capable of supporting 8 virtual PCs per server.VM Workstation used in network labs, to allow students experience installing OSs and configuring administration settings without effecting underlying lab PC.Approached VMWare to customise ESX for Netlab introduced to our neighbours in Ovens, MD ex-CIT graduate

  • VMware ESXInitially, installed ESX for research, had no interest in large scale virtualisation agenda.CIT became a VMware university allowing academic licensing to be used for creating ESX servers.Research includes virtualising an existing server i.e. our TACACS server, as well as creating some new servers for NM (e.g. Nagios, Squid, DNS);

    ESX SERVER 1

  • Computer Dept. SANInitial ESX server was running out of local disk space.School of Computing invested in a SAN.EMC Clarion CX300Initially used in computing as storage

  • Fiber channel switchA colleague in Finance managed an internal WWW server which crashed.Convinced him to buy fibre channel switch instead of new server, if we hosted finance.cit.ie 1st Production serverAn upgrade to phone management server required new server we took this server as our 2nd ESX server and virtualised.Provided high speed link to SAN for storage and retrieval of data from VMware servers.

  • Value of VM AD ProjectCollege undertook to centralise AD 13 different departmental ADs to two central ones Staff and StudentImpossible to build new, parallel infrastructure while old existedVirtualised the whole old AD estate, all 13 ADs, and in this test environment, mocked up the AD migrationImplemented VMMotion

  • CIT TodayServer consolidation ban on new physical serversSAN upgrade, CX400 i-SCSI, mirroring4 ESX Servers, 63 VMs, 15Tb Disk, in two centers

  • Pitfalls Server for server sakeVM Servers/machines have an undoubted value and can be created instantaneouslyHowever, there is a danger in creating VMs for the sake of itThis can lead to unstructured and unmanageable growth of virtualisation infrastructureNetwork admin looses visibility of the port which servers attached vSwitch

  • FutureVSphereCIT plans to upgrade its Virtualisation Infrastructure to VSphere 4.0 in 2010VDICIT plans to investigate VDI as a means of rapid desktop deploymentIt will be also used to deploy individual desktops to Staff and StudentsMost likely pioneered in Dept of Computing and IT ServicesProject Students and CITs Open Access facility for Students could benefit.EMC/VMWare/CIT AcademyCIT over the years has enjoyed good relations with EMC and VMwareRecently CIT have created a VMware Academy Built a VMware Training Infrastructure to support delivery of VMware coursesPlans to offer a number of courses including the VCP in 2010
