1. Sydney Region IT School Support Term 3 2009

2. Smaller Servers available on Contract

3.  Windows 2003 R2 ◦ 64 / 32 bit  Services ◦ AD DS ◦ WINS ◦ DNS ◦ DHCP ◦ Web ? ◦ TS  Storage: ◦ < 500 GB storage  RAM ◦ 1GB

4.  + Single Server  + All services running on one server  - One service can bring down all others.  - Time Consuming to recover

5.  Multiple Servers  Each server providing single Primary service.  + Each service is independent  + Replica of AD  - Expensive solution ◦ Power requirements ◦ Infrastructure ◦ Physical Space ◦ Cooling

7.  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

8.  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)

9.  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.

10. Using Current / Future Servers on Contract

11. Physical Disk Volume Virtual HD

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

14.  + 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.

15.  Reduce Hardware Costs ◦ Less servers required.  Reduce running costs ◦ Power ◦ Cooling  Reduced Infrastructure ◦ Networking requirements ◦ Space requirements

17.  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

19.  SMART - UPS 750VA TOWER -$290.59  SMART - UPS 1500VA TOWER - $370.59  SMART - UPS 1500VA RM (2U) -$467.06  SMART - UPS 2200VA RM (2U) - $1,156.47  SMART - UPS 3000VA RM (2U) - $903.53 ◦ 15 Amp Circuit required (Est ~ $400)

22.  + 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)

23.  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

24.  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
