Smaller Servers available on Contract

Windows 2003 R2◦ 64 / 32 bit

Services◦ AD DS◦ WINS◦ DNS◦ DHCP◦ Web ?◦ TS

Storage:◦ < 500 GB storage

RAM◦ 1GB

+ Single Server + All services running on one server - One service can

bring down all others. - Time Consuming to

recover

Multiple Servers Each server providing single

Primary service. + Each service is independent + Replica of AD - Expensive solution

◦ Power requirements◦ Infrastructure◦ Physical Space◦ Cooling

Dell T610 / R710 2 x Quad-Core Intel(R) Xeon(R) E5410, 64-bit

(32-bit compatible), 2 x 6MB Cache 2.33GHz, 667MHz FSB,80W.

16 GB RAM (support for 96 GB) 5 x 300 GB SAS Drives - 4 in Raid 5, 1 Hot

Swap.◦ Provides 900 GB Storage◦ Support for 8 Drives

Hardware◦ Has vastly exceeded software requirements◦ Cost reduced◦ CPU/BIOS level support for virtualisation◦ Dual Quad Core CPU’s◦ RAM – 16 GB +◦ HDD – 900 GB +

Software◦ Server 2008 R2 64 Bit◦ Hyper V Server

Usage/Demands◦ More Data storage required◦ Demand for more services (especially Web2.0)

Multiple Core processors More RAM than required by OS. 64 Bit OS able to address over 4Gb RAM, CPU/BIOS support for Virtualisation. Virtualisation provides rationalisation of

physical server requirements. Virtualisation offers opportunities to reduce

running costs. Bare Metal Hypervisors enable virtual

machines without the OS overheads.

+ Single Server + Single Backup + VM to support Printing - Single service can bring down server - To restart single services, often require

restart of server.

+ Single Physical Server + Single Backup + VM’s for each service so that no one service

can bring down all others. + Quick restart of services + Quick to provision + Reduction in Power Costs + Reduction in supporting infrastructure - Requires a Management Station (for Hyper V

Server.◦ - Can not be managed from Server.

Reduce Hardware Costs◦ Less servers required.

Reduce running costs◦ Power◦ Cooling

Reduced Infrastructure◦ Networking requirements◦ Space requirements
