1 Webinar Data Center Capacity Management David Cuthbertson, Director Square Mile Systems Ltd

2 Capacity Management - Why? 1. Standards have been referenced for the design, implementation and testing of data centers TIA Good components have been chosen - which rarely go wrong 3. Why does the data center sometimes run out of capacity? delay installation of critical kit?

3 Square Mile Background Develop AssetGen toolsets, training and Business Processes techniques for operational management Departmental, Company of complex IT infrastructure Focus areas Services Connectivity management Data center management Service and CMDB mapping Applications PC, server, mainframe, SOA System change impact analysis Documentation techniques Infrastructure visualisation i Use Visio automation for both diagramming and reporting tool End user, infrastructure, supplier Virtual Infrastructure Network, Servers, Storage, DBMS Hardware Infrastructure Network, Servers, UPS, Storage, Other Fixed Infrastructure (Cabling, Power, Cabinets, Buildings)

4 Best Practices Training Practical Data Centre Management (2 days) Managing the facility and external teams (ITIL, ISO27001, BS25999) How to Map Services and Systems (1 day) Communicating change / incident impact and dependencies (ITIL) Visio for IT Professionals (2 days) Training course on Visio diagramming and automation techniques Creating and Maintaining Visio Infrastructure Diagrams One day iin-house workshop on Visio diagram automation

5 Changing Requirements (Device) The Server requires 1 Power connection 1 or 2 network cables 1 KVM connection Server

6 Todays Requirements (Device) Core Switch SAN Array Power PDU Other D D Edge Switch SAN Switch Power Strip KVM Video Server Min 3 Max 20+

7 Changing Requirements (Environment) Density More servers in a rack (42 1u servers = 84 network cables) More ports on a switch Cabling technology Cat6A cable takes up more space, fibre used for SAN Power Multiple power inputs (HP blade server up to 6) & loading Cooling Must keep within cooling limits and not block airflow Risk One box may have multiple servers so errors are multiplied

8 Changing Requirements (Business) Centralised planning of changes Local knowledge of connectivity resources required Reduce the costs of change Less manual effort, optimise use of hardware assets Faster turn round of tasks Use of workflow & virtual systems (VLAN, storage, servers) Out tasking physical changes Formal instructions / work orders to 3 rd parties Reduce risk of disruption More resilience and alternate paths required

9 Why Manage Capacity? Business IT Computing Needs The Data Center team can t predict hosting and other requirements! - Highlight investment required - React to changes Infrastructure Data Center

10 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 Host, outsource, out task.

How you decide where to put equipment 2. When to say no (or yes) Exceed technical design or operational limits Doesn t conform to the capacity management plan Not optimal use of available resource 3. Establishing authority and ownership Allocation of resources and funding Decommissioning and moving 4. Confidence in service provision UID Everything is working within design limits Failover or resilience will work as required HP ProLiant DL380 G5

12 Practical Issues Who owns the problem of creating and maintaining an end to end data centre capacity management system? Facilities? IT Data Centre teams? Platform teams? Service management? Development teams? Where do you start? People Process Toolsets Is this going to be solved by ITIL configuration management and a CMDB? NO!

13 Capacity Management What do I Mean? Demand Management Requests / Reservation Reviews Performance Management Monitoring & Analysis Tuning / Optimisiing Modelling Placement options, current limits Heat flow, resilience, fail over Capacity Communication Capacity plan, energy usage Reporting (Current and Future) Workflow System Monitoring Systems Life cycle controls Resource management Infrastructure Documentation Space Power Cooling Connectivity Inventory Projects Monitoring of current state Alerting
