  1. High School Server Sydney Region IT School Support Term 3 2009

  2. Traditional Approaches Smaller Servers available on Contract

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

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

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

  6. What has changed?

  7. Current Server Hardware • 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. What has changed • 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. Industry Factors and Trends • 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. New Approaches Using Current / Future Servers on Contract

  11. Very Large Server, 1 VM Physical Disk Volume Virtual HD

  12. Very Large Server, 1 VM • + Single Server • + Single Backup • + VM to support Printing • - Single service can bring down server • - To restart single services, often require restart of server.

  13. Hyper Visor + VMs

  14. Hyper Visor + VMs • + 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. Why Virtualisation? • Reduce Hardware Costs • Less servers required. • Reduce running costs • Power • Cooling • Reduced Infrastructure • Networking requirements • Space requirements

  16. Backup Options

  17. Backup Options • 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

  18. UPS

  19. APC UPS from Dell (OEM prices)(When Purchased with a server) • 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)

  20. Future Directions?

  21. Server + Direct Attached Storage

  22. Server + Direct Attached Storage • + 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. Future Directions - Hardware • 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. Future Directions - Software • 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
