South Dakota Infrastructure and Roadmap

South Dakota VMUG Meeting

November 3, 2011


Virtualization background

Virtualization Background

  • Initial Infrastructure

    • Two Datacenters on campus

    • Pieced together infrastructure

      • Agency based projects drove the initial infrastructure

      • Servers were sized to meet the agencies projects

    • Two HP C7000 blade chassis

      • BL 460s and 490s servers

    • VMware ESXi version 3.5

      • Upgraded to vSphere 4.0 ESXi

    • Existing FC based storage served by HP EVAs

      • Hosting physical server workloads like Exchange, SQL, and file services

    • Multiple 1G Ethernet connections

      • Connections were configured using Ethernet pass-through modules to networks already in place.


Initial deployment challenges

Initial Deployment Challenges

  • Chassis standardization

    • Needed a more consistent compute platform across the farm

  • Storage

    • No array based replication between datacenters

    • No VAAI support

    • No FC network in Madison

  • Network

    • Cable Management

    • Lack of network continuity between all ESX hosts


Goals

Goals

  • Immediate goals

    • Server consolidation

      • Virtualize First Policy

      • Keep infrastructure current (covered under a hardware warranty)

    • Provide high availability for all virtual systems

    • Solution must be flexible and scalable

    • Keep it simple

    • Foundation built to add VDI

  • Long term goals

    • Geographic Datacenter Protection

      • Site Recovery Manager

      • Reed network / Madison

    • Datacenter portability and self provisioning services.

      • vCloud Director


Updated design

Updated design

  • New Infrastructure

    • Multi-site design

    • Dual socket HP BL460c servers

      • 6 core Nehalem processors

      • 96 gigs of ram per host

    • VMware ESXi version 4.1

      • Planning on moving to vSphere 5

    • 10G ISCSI storage using HP P4500/P4800 infrastructure

      • Network RAID 10 across datacenters

    • Redundant 10G Ethernet connections

      • Juniper Core with Layer 2 connectivity between Datacenters

      • Nexus 1000v virtual switch and VLAN tagging


Current statistics

Current statistics

  • VMware Farm Summary

    • 42 hosts

    • 455 Virtual Machines

    • 5 clusters

    • 81 Data stores

  • Workloads being virtualized today

    • Web and application Servers
