Presentation Transcript
fiber plant capacity
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  • 24 pair of Multimode, outdated, little value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
network capacity
Network Capacity

data center capacity
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
security capacity
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
systems capacity
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
storage and backup capacity
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
how we got here
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
what we did with the money cont
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
what we did with the money cont1
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
what we did with the money cont2
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
what have we done since then
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

what have we done since then1
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

addressing the gap
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
addressing the gap1
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
addressing the gap2
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
budget and strategic planning
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
budget and strategic planning1
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
