Enabling Private Clouds with OpenStack

OpenStack is the most predominant technology used for Private Cloud build outs

In less than 5 years ..– 25,000 members– 500 companies in 160 countries– 20+ million lines of code

Why Private Cloud?

Worlds largest brands on OpenStack– Best Buy, Walmart

– AT&T, Comcast

– PayPal, Bloomberg, American Express, Fidelity

– Cisco Webex, Intel, TRUSTe, Cigna, Disney, …


Why OpenStack?

Ability to Innovate Less on Infrastructure maintenance and more on Applications and Innovation

Open Technology Greater Flexibility, Interoperability, Faster Innovation

Cost Savings Eliminate most licensing costs, expensive support renewals.ROI: 101% with 15.5 month payback2

Avoid Vendor Lock-in No Vendor lock-in for products, services, proprietary APIs and onerous switching costs

Top Reasons for adopting OpenStack1


Ideal Storage for OpenStack

• Ceph – The most widely used OpenStack Block Storage• 45% of OpenStack Block Storage runs on Ceph*

• More than just “another” OpenStack Driver• Ceph is integral to OpenStack Cinder block storage• Shares the same open source community development roots

• Overcome the performance limitations of OpenStack with InfiniFlash HW optimizations

• Scale horizontally on demand- architecture built for scale• Fully tested & proven for OpenStack deployments• Hardened and tested for PB-scale deployments and

workloads• Single vendor support for both hardware and software

+


One Storage Platform for All OpenStack StorageUnified Scale-Out Storage System for Hyperscale

• Unified – One platform for all OpenStack workloads, iSCSI applications and more …• Heterogeneous – InfiniFlash flexible architecture allows for performance tuned configurations for multiple workload

Disaggregation is the Key to Breakthrough Economics !

InfiniFlash™

Old Model Monolithic

Proprietary storage OS

Costly: $$$$$

New Model Disaggregated Open software stack Green ! High performance Cost effective

Software Defined Storage

Standard X86 Servers

Advantages of Disaggregation

Lower TCA and TCO than traditional models

Rich choice of ecosystem partners - compute, networking and software stacks

Evidence

Decline of traditional frame array business


InfiniFlash for OpenStack with Dis-Aggregation Compute & storage disaggregation

enables optimal resource utilization - Allows for more CPU usage required for OSDs with

small block workloads- Allows for higher bandwidth provisioning as required

for large object workload

Independent scaling of compute and storage

- Higher storage capacity needs do not force you to add more compute and vice-versa

Leads to optimal ROI for PB scale OpenStack deployments

SanDisk focuses on flash optimization of Ceph andlowering the cost of flash integration for Ceph * Future Ceph Roadmap


IF500 - Enhancing Ceph for Enterprise ConsumptionSanDisk Ceph Distro adds usability and performance utilities

without sacrificing Open Source principles

All Ceph Performance improvements developed by SanDisk are contributed back to community

Open Source Ceph with SanDisk Performance

Improvements

Reduce the replica count with higher reliability of flash

- 2 copies on InfiniFlash vs. 3 copies on HDD

InfiniFlash disaggregated architecture reduces compute usage, thereby reducing HW & SW costs

- Flash allows the use of erasure coded storage pool without performance limitations

- Protection equivalent of 2x storage with only 1.2x storage

Power, real estate, maintenance cost savings over 5 year TCO

Before With IF500….. Customer deployed OpenStack-based private cloud

on Community Ceph

Pain-points

• Cinder storage based on Ceph being used on HDD+SSD could not get over 10K IOPS

• Limiting private cloud expansion from including higher performance applications

Solutions considered before IF500

• Alternate solutions with separate storage architecture for high performance applications add significant costs and higher management overhead defeating the purpose of OpenStack

Meet higher performance goals with the same IF500 Ceph-based architecture without changing existing infrastructure

• Ceph cluster on HDD will co-exist with IF500 Ceph cluster. Applications deployed on either based on performance needs

• High performance workloads migrated to InfiniFlash:

Splunk log Analytics Apache Kafka messaging system

Adding performance in lower TCO footprint• 2 x 128TB IF500 expanding to 256TB next phase• Expected to reduce real estate to < 1/3 • >50% power reduction expected
