virtualization for sql

Andrew FryerMicrosoft UK Ltd

Computerworld“Although virtualization has been

the buzz among technology providers, only 6% of enterprises have actually deployed virtualization on their networks, said Levine, citing a TWP Research report. That makes the other 94% a wide-open market.”

The Rise of the Virtual Machine and the Real Impact It Will Have“We calculate that roughly 6% of

new servers sold last year were virtualized and project that 7% of those sold this year will be virtualized and believe that less than 4% of the X86 server installed base has been virtualized to date.

Information Week Oct. 2007

“The [virtualization field] is nowhere near saturated. IDC estimates that only 17% of the worldwide server market will be virtualized by 2010, up from 5% in 2005.”

x64 server with hardware assisted virtualization

AMD AMD-V or Intel VT

Hardware enabled Data Execution Prevention (DEP) required

AMD (NX no execute bit)Intel (XD execute disable)

Note: Enabling these BIOS features requires powering down (not rebooting) the server to take effect

IsolationNo sharing of virtualized devicesNo sharing of memoryVMs cannot communicate with each other, except through traditional networkingGuests can’t perform DMA attacks because they’re never mapped to physical devicesNeither Guest nor Parent Partitions can write to the hypervisor

Not able to run SQL server on core until Windows 2008 r2
