Bowdoin College
Background
Bowdoin College IT environment Expanding Technology Requirements New Resource Needs
Spring 2004
Service Demands Datacenter Resources Projected Growth
Service Demands
Test and Validation InfrastructureNo standard test and validation environmentNo development arena
Ease of Management Increasing demands, Static staffing
Higher AvailabilityFault tolerance, Quicker response
Datacenter Resources
Space and ResourcesFloor and Rack Space LimitedPower/UPS/AC TaxedKVM Capacity Stretched
Replace/Retire Old ServersService costs exceeding replacement
Projected Growth
New Financial SystemMSSql/IIS based ApplicationTerminal Services for Mac usersHA/FT design requirement
Extensive List of Projects/ServersProjected 6-8 new servers
Problem Statement
We need to find a solution to our space and resource problem.Address Hardware and Physical limitationsSupport our diverse systems environmentProvide best use of staff resourcesConsolidate to better utilize server resources
Hardware Requirements
High Density, Rack Mount Console-KVM-Cabling UPS-Power-AC Redundancy-FT-HA Industry Standard
Hardware: HP Blades High Density
40 servers in 36U Rack ILO for KVM and media Integrated Power Enclosure
Redundant AC feeds and power supplies Integrated Switches
no direct cabling Redundant network paths
Software Requirements
FlexibilityMultiple OS support
ManagementEase of UseRapid deployment
Backup and Recovery Industry Standard
Software: VMWare ESX Server
“Bare Metal Install”Licensed per server, not per VMEach VM assigned the same virtual hardwareVMs portable between different ESX servers
Image and Deploy servers in minimal time Multiple Drive States
Use of “REDO” for changes VM is comprised of 2 files for backup
Task List
Build ESX infrastructure on HP Blades Create Testing infrastructure Migrate/Retire older servers Build new Financial System Build for future growth Change the mindset of IT at Bowdoin
Task: Put ESX onto HP Blades
Build knowledgebase for both products Install ESX on older DL380s Install Windows and Linux on Blades
Bring together both technologies Integrate into Bowdoin’s infrastructure
Mount common NFS share ISO and binary storageBackups, both physical and virtual
Task: Create Testing Infrastructure
Build virtual servers as “sandboxes”Programmers and developersApplication support and upgradesStandardization of platformsBackup and recoverySelf-service option
Task: Migrate or retire old servers
Replace older hardware with virtualApplication upgrades on VMsP2V migration for static servers
“Plan for Virtual, move to Physical”New upgrades or migrations are done to
virtual servers first. If more resources are needed, it is moved to a blade at that time.
Task: Financial System Buildout
MSSQL-IIS Application baseMac users will need accessMust be Highly Available at all phasesFault TolerantProven patches and updatesFlexible, able to scale as needed
Financial System Solution
16 servers, both physical and virtual3 Blades, in an Activex3 SQL cluster2 VMs: NLB IIS cluster for Web access2 VMs: NLB TermSvc cluster for Mac users1 VM: Application Management server4 VMs: Staging servers: Sql, IIS, App, TS4 VMs: Testing servers: Sql, IIS, App, TS
Task: Build for future growth
Create Server ImagesGold Win2k3 and Linux serversScale ESX servers for growth
VM resource allocationScale servers at a common base Increase disk, memory, CPU as needed“Added resources make happy customers”
Task: Change the mindset of IT
“Plan for Virtual, move to Physical”Projects begin with virtual serversCharge/spec for “Server Resources”
Prove patches and upgrades in VMBeat up on a Clone
Spread the wealthseparate file, web, and databases for security
Bowdoin Systems Today
46 X86-based servers 15 HP BL20 Blades 9 ESX servers on 8 Blades +1 Dell tower 118 X86-based hosts 66 of them are VMs, or 56% virtualized
Savings
Cost of each Blade: $6,250.00 Includes Disk, Memory, Dual Proc, etc.
Number of additional servers: 66 virtual-9 ESX servers=57
Cost to provide physical Servers
57 x $6,250= $356,250.00 ** Bowdoin did not purchase servers in FY05-06
Conclusion
Server Consolidation is here and now Consolidation can be done by anyone with
a little time, resources and determination The benefits can be dramatic Your boss will be happy
