Capacity Management Why?Capacity Management - Why?

1 Standards have been1. Standards have been referenced for the design, implementation and testingimplementation and testing of data centers – TIA942

2. Good components have been chosen - which rarely go wronggo wrong

3. Why does the data center3. Why does the data centersometimes run out of capacity?delay installation of critical kit?

Changing Requirements (Environment)Changing Requirements (Environment)

• Density– More servers in a rack (42 1u servers = 84 network cables)

More ports on a switch– More ports on a switch

• Cabling technology – Cat6A cable takes up more space fibre used for SAN– Cat6A cable takes up more space, fibre used for SAN

• Power– Multiple power inputs (HP blade server up to 6) & loadingMultiple power inputs (HP blade server up to 6) & loading

• Cooling– Must keep within cooling limits and not block airflowp g

• Risk– One box may have multiple servers so errors are multiplied

Changing Requirements (Business)Changing Requirements (Business)

• Centralised planning of changes– Local knowledge of connectivity resources required

R d th t f h• Reduce the costs of change– Less manual effort, optimise use of hardware assets

• Faster turn round of tasks• Faster turn round of tasks– Use of workflow & virtual systems (VLAN, storage, servers)

• Out tasking physical changes• Out tasking physical changes– Formal instructions / work orders to 3rd parties

• Reduce risk of disruptionReduce risk of disruption– More resilience and alternate paths required

How Are Most Data Centers Managed?How Are Most Data Centers Managed?

• Informal / formal processes• Site survey, pre-installation checks, audits • Ownership is often assigned locally• Create knowledge sets as individuals or within teams

– MS Office - Excel, Visio, Word, Notes, Sharepoint, Access– Specialist toolsets AssetGen, Aperture, Nlyte and others

• Or give the problem to someone else• Or give the problem to someone else– Host, outsource, out task.

Capacity Management in PracticeCapacity Management in Practice

– Exceed technical design or operational limits– Doesn’t conform to the capacity management plan– Not optimal use of available resource

Making Capacity Management EasierMaking Capacity Management Easier

• Develop common processes and standards for changes– Naming and labelling

Easier project / operations handover– Easier project / operations handover– Reservation of capacity and connectivity in operational systems

• Focus on reducing the number of data setsFocus on reducing the number of data sets– Spreadsheets– Databases– Diagrams– Documents
