Server Virtualisation - IPEXPO Pathfinder


Published on

Claus will talk briefly about the development of server virtualisation from its inception in the 1960s as a way of sharing scarce resources, through improving the competitive standing of Unix machines in the 1990s, VMWare and consolidation in the early 2000s, to its current status as the foundation of Cloud Computing. Claus will also address the the approach of the storage vendors to complement server virtualisation.He will focus on the key questions IT Managers should be asking as vendors push virtualisation.

  2. 2. Question:• What is the single most important benefit of virtualisation?• My answer: versatility of the Swiss army knife of virtualisation is the benefit Copyright 2
  3. 3. Why Virtualisation?• Pre-historic 1960s – yes, about money – Capex• Memory prices were extortionate – So expensive the vendors had to do something• We did not know the power of software – Electronics was the holy grail Copyright 3
  4. 4. Memory prices over time Price/MB$100,000,000.00 • OK, old news? $10,000,000.00 • Until hardware caught $1,000,000.00 up with our needs, $100,000.00 software sorted us out $10,000.00 • Virtualisation boosted $1,000.00 processor exploitation, $100.00 workloads became $10.00 dynamic, performance could be manipulated $1.00 $0.10 • And, storage looked $0.01 dumb. Really dumb! Logarithmic 1960 1970 1980 1990 2000 2010 Copyright 4
  5. 5. But storage responded• It became a proper • Data can reside across ‘storage computer’ several tiers• Separating capacity • Remote copy to provide from hardware fail-over• Log structured files • Followed by: De- fixed in-place update duplication & CDP• Index enabled snap- • Storage preceded X86- shots Virtualisation!• And thin-provisioning • But server virtualisation ‘sweats’ storage!!

  6. 6. Minimum server ambitions? Fill up servers Then: Group to desktop manage DR/BC VMs Automate Host in the Dashboards cloud Portability Copyright 6
  7. 7. How would you like to pay, Sir?The vendors get creative:• Per server• Per core• Per socket• Metered• Tiered• The free market rules? Copyright 7
  8. 8. 4 Questions for the vendors• How are you bridging server and storage virtualisation?• How are you enabling seamless management of the virtualised IT resource?• How are you promoting a virtualised world of DR?• Insist on the ‘what-how’ explanation of how IT Cloud can bring real benefits!
