2 hillsgrammar.nsw.edu.au inaburra.nsw.edu.au The How, What, When, Where and Why of The Nutanix Implementations at Hills Grammar and Inaburra Schools

3 A little about Hills Grammar School Independent non-denominational Early Childhood to Year 12 > 900 students ~ 150 FTE equivalent staff Hills Grammar Friday, May 13, 2016

4 A LITTLE ABOUT INABURRA K-12, co-educational, 1000 students, 150 staff Bangor, NSW

5 The Old Infrastructure A Storage Problem HP C7000 Blade Centre Hitachi AMS2100 SAN QNAP NAS s HP DL360 Servers HP DL380 Servers HP StorageWorks MSA1000 Hills Grammar Friday, May 13, 2016

6 THE OLD INFRASTRUCTURE A VIRTUAL PROBLEM! Challenges All servers were standalone physical servers no shared storage, no hypervisors. Multiple backup methods No redundancy Low utilization most servers sitting below 10% CPU. Poor off-site RTO Goals Single backup architecture Improve off-site RTO Improve redundancy Improve efficiency Improve flexibility

7 Project Goals Reduce Risk Increase Capacity Increase Versatility Reduce Costs Hills Grammar Friday, May 13, 2016

8 Why Nutanix? Met or exceeded all selection criteria Hyper-converged solution provides a Flexible Web-scale architecture Offered Integration with existing Cloud Platform Depth of Support & Net Promoter Score Roadmap of Development Well positioned in Gartner and IDC Hills Grammar Friday, May 13, 2016

10 What is a Hyper-Converged Architecture? Hyper-convergence (hyperconvergence) is a type of infrastructure system with a softwarecentric architecture that tightly integrates compute, storage, networking and virtualization resources and other technologies from scratch in a commodity hardware box supported by a single vendor. - TechTarget Hills Grammar Friday, May 13, 2016

15 Benefits Realised All critical server room equipment under maintenance All critical systems virtualised Alleviation of storage restrictions Improved RTO Reduction of power usage in data centre * Future Benefits Azure Site Recovery Flexible architecture Hills Grammar Friday, May 13, 2016

16 THE BENEFITS Now Simplicity no SAN! Single-click upgrades. Single backup architecture N+1 redundancy Improved RTO Rapidly improving software compression, features etc. Easy scalability Implemented mid-term with no downtime during school hours. Future Hypervisor agnostic single click migrations. Single management interface for public cloud single click migrations.
