DNS Arrow Virtualisation and the business opportunity it presents. Steve Pearce Managing Director

Virtualisation is being presented as the answer to many of these issues – Why ? Virtualisation enables the consolidation and sharing of IT resources through a single, easy to deploy management interface. The objective being to simplify and get the most from IT infrastructure investment whilst curbing unnecessary spend. Simplification Consolidation Centralisation Cost saving It’s all about ……

Why is this happening now ?  Simplification & consolidation has always been an IT managers objective.  BUT :  new technologies from companies such as VMWare and Citrix are enabling this to be actually implemented far easier than ever before.  Networks have become much more reliable, faster and cheaper in recent years and ‘ Thin client’ technologies and network acceleration devices that make this a practical reality.  The pressures on IT resources and IT infrastructure is now so great that end users have to do something.  In simple terms- it is now possible to do this and make it work with real return on investment.

Why is this a business opportunity for our resellers?  IT professionals who are implementing server virtualisation remain very bullish on its future use:  On average, 7% of installed servers are virtualised and 49% of new servers purchased next year will be virtualised *  Server virtualisation is driving Storage virtualisation.  The take up is happening & the market is growing  Virtualisation business cases do stack up and end users are realising this will save them money.  End users will adopt this model for sound financial and business reasons.  They will spend money on this and will want help.  If our resellers do not have a strategy a competitor could use this to get into one of their key customers. * Source: IDC

5 Areas of Virtualisation within IT Infrastructure System Architecture Break it down make it simple

Implementing Storage Virtualisation

Why implement Storage Virtualsation & Data Management ?  Support wider server virtualisation strategies.  Increase storage utilisation - better provisioning  Simplify and enhance data protection  Virtual tape libraries  Manage data across appropriate tiers of storage  Reduce the occurrence of duplicate data  Take complexity out of the storage infrastructure – get everything under control

Storage Virtualisation Before  Multiple/diverse storage devices and management interfaces  Server attached, spread around the enterprise  Wastage and poor utilisation  Poor management control  One type of (expensive) disk fits all data  Spend ahead of usage - capacity planning challenges  Diverse backup and business continuity policies  High power consumption and footprint SAN Storage Virtualisation

After  Single management interface to storage pool  Thin provisioning  Reduce number of storage devices - less disk, same capacity  Cost effective tiered storage and de-duplication of data  Easier deployment of extra capacity  Reduced power and footprint SAN Storage Virtualisation

Continuous Backup, Zero Server Impact The Problem  High server utilisation  No spare cycles for backups  Tape is slow, complex and expensive  DR is very difficult VM1VM2 CPU Utilization Disk-to-Disk solution  Servers run apps, not background processes  Instantaneous backup and recovery  Low storage overhead using storage pool capacity  Application consistent CPU Utilization VM1VM2 Virtual Storage Pool VM1VM2 Backup, disk-to-disk Within the storage pool SB1SB2

Data De-Duplication  Significant amounts of data are duplicated  For example, attachments, copies of files and documents  Also backed up daily, using up unnecessary amounts of data storage resources  De-duplication identifies the same files  Sets up a process to keep one copy and  Provides a tag in all other occurrences of this data directing the system to the master image  De-duplication can be presented at different levels of the system architecture  VTLs  Backup systems  systems  Useful when keeping data for longer periods, especially if the access frequency is not too high  Enables a significant reduction in storage space to be realised  Particularly relevant with unstructured data  Archives  Content managers  Disk arrays

Information Lifecycle Management (ILM) and Archive  Archiving data is a necessary part of each organisation’s information management strategy  Data must be maintained on a storage system that manages obsolescence  Data may need to be kept for 7 years, 10 years, 20 years or more  ILM provides a framework by which a clear set of policies and practices can be defined and implemented  Policy based data protection and data migration to cost effective storage  Content aware management practices  Organisational management that keeps an audit trail of activities, for example,  When data is migrated to archive  Deleting data that does not need to be retained DaysWeeks Life of Document / File MonthsYears Frequency of Access High Low Decades Immediate Operational Requests Long-Term Archival Storage Operational Reference Requests
