9. Challenge of Virtualization

10. Virtualization Dilemma - The Storage Bottleneck
• Multiple VM scramble I/O into random stream
• High random access strains shared storage infrastructure
• Concurrent & “IO blender” aggravate the I/O bottleneck
• Over provisioning HDDs leads to under utilization
• Applications being designed for low latency, high IOPs

12. Advent of Solid-State Drives

13. Solid-State Drives Technology
Citrix Synergy 2015May 12-14, 2015
•CPU = 175x vs. HDD IO = 1.3x
•IOs reach the spindles in a random
fashion
•Gets worse with higher # of apps or
VMs per LUN
•SSDs $30/GB -> <$1/GB (‘08-’15)
•Lower TCO than HDD ($, Watts, Space)
•$ / IOPS better for SSDs ($0.01 vs $0.80)
•SSD are reliable (2MHr MTBF)
SSDs
Now cost effective, reliable means to address storage
bottleneck in virtualized environment
