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

•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

Applications that Work Better with SSDsScaling enterprise applications
Private Cloud DatabaseVirtualization Big data
NVMe SSDs lower enterprise IT TCO by
enabling increased Virtual Machine scalability and
optimizing platform utilization
Software Defined Infrastructure or hyper convergence is made affordable with high performance SSDs
Consistent, low latency, high bandwidth
performance of NVMe shines in traditional relational databases
Analytics and NoSQL databases fully utilize NVMe performance to provide near real time
results
NVMe keeps up with high bandwidth demands of
HPC to speed up overall workflow times by an order of magnitude
