Sydney Region IT School Support
Term 3 2009
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.
Using Current / Future Servers on Contract
Physical Disk
Volume
Virtual HD
+ 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
Need to cater for at least 3 x possible data storage.
1. External Hard drives◦ 3 x 1TB USB External Drives◦ Eg Seagate Freeagent 1TB Silver 3.5" External HDD
$170 (ex GST)
2. Network Attached Storage (NAS)◦ 2-4 TB NAS located somewhere else in school on Gb
Link◦ Buffalo TeraStation Pro II TS-RH4.0TGL/R5 - NAS - 4
TB - rack-mountable - Serial ATA-15 - $1,601.82 (ex)
◦ Prices from Harris Technology

SMART - UPS 2200VA RM (2U) - $1,156.47
SMART - UPS 3000VA RM (2U) - $903.53◦ 15 Amp Circuit required (Est ~ $400)
+ Easy to expand storage as required.◦ MD1000 supports up to 15 TB◦ MD3000 supports up to 45 TB
+ Can be connected to up to 2 servers ◦ Redundancy◦ Storage shared between Servers
MD1000 with 4 TB Storage ~ $4399 (ex gst)
How much Useable Storage is required?
Move to 400GB SAS Drives?◦ How many, configuration?
Is DAS more suitable than internal Drives?
Move to 32 GB RAM?
Backup???◦ How do you backup Multi Terabyte storage
What services are required?◦ AD DS, DHCP, DNS, FS, PS – required◦ Web?
IIS or Apache Moodle, CMS, Web2.0?
◦ Windows Deployment Services◦ DFS◦ NAP
Virtualisation... DAS / NAS / SANS
