Lessons Learned

Server blades remain a key platform for future enterprisecomputing strategies

TCO is necessitating a push towards IT simplification that drivesthe server market today and in particular server blades Power and cooling issues remain front of mind for IT and data

centre managers today and for the near future Awareness of internal political struggles critical:

Disparate groups do not share data and probably won't care to start doingso

Requires sensitivity to change management challenges Work in phases - start with small pilot, gradual rollout

Hidden costs exist as there is no way of knowing what will really beuncovered as work begins

Undocumented processes are a huge and costly challenge

Approach to Capacity Planning

Two product options available: VMware Capacity Planner

Hosted and chargeable service from VMware partner Data collected from servers via WMI API

PlateSpin PowerRecon

Product from PlateSpin that provides a local data collection andreporting client PowerRecon is very functional tool but it has higher cost that VMware

Capacity Planner


20/67


Capacity Planning Outputs

Server inventory including hardware specification Virtualisation exclusions

Specialist hardware (such as FAX servers) High paging rates High I/O High CPU utilisation

MSCS clusters (not specifically excluded but problematic) Multiprocessor imbalances Server anomalies and alerts

Identify and resolve problems in advance of starting virtualisationto reduce risk and increase success Consolidation scenarios

Stage 4 - Backup and Recovery

Hot backups, restores and disaster recovery of the virtual servers can beperformed over the LAN or WAN

Consolidated backup No agents on virtual servers

Server replication Virtual machine replication using third-party products such as VizionCore Virtual server replication using third-party products such as DoubleTake,

WANSync, Replistor

Disaster Recovery Business Continuity Two options (not mutually exclusive)

Existing (virtual) server backup NetBackup Tivoli Storage Manager Data Protector CommVault

Virtual server consolidated backup Third-party tool - esxRanger

Monitoring

Monitoring will arise in two areas Monitoring virtual servers (and their applications) Monitoring underlying hardware

Tools such as HP Systems Insight Manager and DellOpenManage run in the virtual server Cannot provide hardware alerts in a virtual environment

Can use monitoring tools such as Microsoft SystemsCenter Operations Manger (SCOM) or HP OpenView Monitor entire environment

Upgrades andpatches aredistributed asbundles. Bundles areclassified as security,critical or general

You must subscribeto receive VMwarepatches. They aredistributed monthly

Virtual Server Patching

Windows (and other)servers will be requiredto be patched as

normal VMware can assist in a

server patching strategy Allow server snapshots

to be taken beforepatching takes place

Reduce the testingeffort by allowing anelement of implicittesting where, unlessproblems occur, thepatches remainapplied
