•  Flash: Enables New Storage Architectures

•  Flash is 50x – 2,000x faster than HDD –  110K/140K IOPs R/W from 360GB

MLC PCIe card1

–  Less than $0.10 per IOP

•  Eliminates the need to stripe across 100s of HDDs

•  Enables high performance server-side storage

•  Cloud: Enables Cost-Effective Storage

•  Highly scalable, pay-as-you-go •  Access through standard APIs

•  Low cost for capacity –  $0.05 per GB per month2

•  Forecasted to grow at 40% annually to 20183

Virtual SAN Puts The App In Charge •  Simpler and Automated Storage Management Through Application-

centric Approach

24

Today

1. Pre-define storage configurations

2. Pre-allocate static bins

3. Expose pre-allocated bins

4. Select appropriate bin

5. Consume from pre-allocated bin

1. Define storage policy

2. Apply policy at VM creation

Resource and data service are automatically provisioned and maintained.

Running a Google-like Datacenter •  Modular infrastructure. Break-Replace Operations

28

"From a break fix perspective, I think there's a huge difference in what needs to be done when a piece of hardware fails. I can have anyone on my team go back and replace a 1U or 2U servers. … essentially modularizing my datacenter and delivering a true Software-Defined Storage architecture."

— Ryan Hoenle Director of IT, DOE Fund
