Challenge of Virtualization

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

Advent of Solid-State Drives

Solid-State Drives Technology


•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
