OpenStack – New Cloud Operating System
11
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, …
SanDisk Confidential 12
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
SanDisk Confidential 13
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
+
SanDisk Confidential 14
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
SanDisk Confidential 16
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

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
