  1. Appalachian State University Information Technology Infrastructure & Systems

  2. Network and Computing Infrastructure – what is it?

  3. Fiber Plant Capacity • Current fiber plant built in early 1990s • ~72 pair of Single Mode, long distance & high speed • 24 pair of Multimode, outdated, little value • Design connects Data Centers and Distribution buildings via redundant paths • Distribution buildings to others is single path • New 144 pair paths are being pulled to tie Raley to StateFarm DC

  4. Network Capacity • Wired Connections ~40000 ports • Wireless Connections • 98% of internal space is covered by wireless canopy • 1759 access points: 915 ResNet + 844 Admin & Academic • 7000 average users/day with peaks to 12,000 • 30% of our bandwidth with peaks to 60% • Registered Clients • 48,016 registered devices on the network • 24,494 student devices • 412 Servers providing services to the world (272 Central & 141 Distributed)

  5. Data Center Capacity • Primary Data Center – Raley Hall • ~2200 SqFt / Very near capacity • (8) Server racks - 272 rack units • (6) Storage racks – 252 rack units • (6) Network racks – 252 rack units • 360KW Back up generator • (3) 10 ton Air handler units • (3) UPS – 220Kw battery backup • Secondary Data Center – Anne Belk Hall • ~600 SqFt / Capacity exhausted • Bond growth taxed our Data Center capacities • More computers -> More power -> More cooling REPEAT

  6. Security Capacity • Firewalls: Internet edge and between Border and Core • VPN: Protect and provide remote access to protected services such as INB Banner and Ustor • Intrusion Detection: Monitor traffic signatures for threats to the network and/or clients • Virus Protection and Quarantine Process: Manage stability and integrity of network, infected devices removed from the network until cleaned and stabilized. Average deleting and cleaning >100 virus infections/month • Spam Filters: Filter >70% of the email that hits our servers

  7. Systems Capacity • ~132 Physical Servers • 13 of these provide virtualization service for 308 VMs • Operating Systems distribution • 256 Windows Servers • 141 Linux Servers • 30 SUN/Oracle Solaris

  8. Storage and Backup Capacity • Storage and Backup Services • Two storage architectures • Banner/Email – 27Tb total 17 Tb used • EMC Disk-based backup - 87% Data reduction thru compression and deduplication • Other Enterprise App. Storage and Departmental/User • 21.9 Tb total 16.3 Tb used (80% usable limit) • NetApp Disk-based backup – 65 Tb total 44.8 Tb used • Tape library – 219 tapes ~500 Tb of data

  9. How we got here. • 2000 – NC Infrastructure Bond. (2000-2007) • 4+ Million dollar infusion in to IT infrastructure and Capital Building projects. • One time money primarily earmarked for • IT Infrastructure • Building Infrastructure • Network Infrastructure • Security Infrastructure • Systems Infrastructure • Data Center Infrastructure • Capital Building Projects

  10. What we did with the money (cont.) • Building & Fiber Infrastructure upgrade • Built additional capacity into campus fiber plant • Upgraded building wiring to cat 5 specification • Network Upgrade • Forklift upgrade of all Network electronics • Core and Distribution routers – 1 GB connectivity • Edge switches - 10/100 MB port for every office • Expanded Wireless to near 100% campus coverage for convenience use

  11. What we did with the money (cont.) • Data Center Upgrades • Established 2nd Data Center in Belk • Began building High Availability services • New HVAC Units providing more cooling • New UPS units to power more equipment • New generator for Belk for backup power

  12. What we did with the money (cont.) • Security Upgrade • Implemented Intrusion Prevention • Implemented & Upgrade Firewalls • Systems Upgrade • Purchase Sun E2900 Server in 2003 for Banner • Upgrade to Email and Portal Infrastructure • Storage Area Network • Purchased Initial SAN storage in ~2003

  13. What have we done since then? 2000-2007: Tremendous growth, no refresh plan and realization of managing enterprise resources and data center capacity 2008: Banner and Email Storage to SAN ($525K), upgraded storage drives, split Banner out to SUN Storage. 2009: Upgraded NetApp controllers and added storage shelves 2010: Implemented Intrusion Detection technology

  14. What have we done since then? 2011: Replace Banner servers ($250K) 2012: Upgraded Core, Border, and Distribution routers to 10+ gig ~$1.2 mil (operational lease), Invested ~$400,000 in wireless infrastructure 2013: Rebuilt/upgraded campus edge/firewall hardware to 10Gig. ~$225k, Upgraded network bandwidth from 1 gig to unlimited - $155k/year, Upgrade IDS to accommodate 10 Gig 2013

  15. Addressing the Gap • End of life – Much of what we purchased in 2000-2007 has reached its vendor supported end-of-life. • Security & Feature Updates are no longer developed • Rely on 3rd party support for much of our Enterprise services

  16. Addressing the Gap • Network edge - Self Support maintenance model since 2010 • Next Gen Technology identified, refreshing as funds become available. • Security - Encryption, policy, data loss prevention, PCI, scanning tools • Several services/applications and their systems are showing age. Portal and Email technologies are 8+ years old. • Most storage on the SAN will reach EOL in 12-24 months. Consolidating storage strategies and developing the use of cloud storage will create efficiencies in management and budgeting • Evaluate our service catalog and refresh technologies where necessary

  17. Addressing the Gap • Proposed Data Center – State Farm Warehouse • ~3000 SqFt • Capacity will be initially 1.5 times Raley • Growth to ~3 times Raley • Will become Primary & potentially our only DC • Implements current technologies to optimize environmental efficiencies • Funded primarily through Energy Performance contracts

  18. Budget and Strategic Planning • Governance Portfolios to assess, manage and set strategy for technology services • Master plan for network and computing infrastructure investments • Fiber plant strategy consultation • Network and Telecom convergence model • Security program and strategy • Put vendors head to head on server solutions • Developing storage plan focusing on cloud

  19. Budget and Strategic Planning • Budget Sustainability • IT budget was originally divided between operation costs and growth(refresh) costs. • Bond and subsequent investments created imbalance – Maintenance consumes greatest percentage of operating budget • Need to work toward budget model that supports strategic investment AND refresh cycle
