New Storage Tiers Are Rapidly Growing
7
• 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

Two Ways to Build a Virtual SAN Node • Completely Hardware Independent
15
1. Virtual SAN Ready Node
…with multiple options available at GA + 30
Preconfigured server ready to use Virtual SAN…
2. Build Your Own
…using the Virtual SAN Compatibility Guide*
Choose individual components …
SSD or PCIe
SAS/NL-SAS/ SATA HDDs
Any Server on vSphere Hardware Compatibility List
HBA/RAID Controller
Note: For additional details, please refer to Virtual SAN VMware Compatibility Guide Page Components for Virtual SAN must be chosen from Virtual SAN HCL, using any other
components is unsupported

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.
Virtual SAN Shared
Datastore ✖ Overprovisioning
(Better safe than sorry!) ✖ Wasted resources, wasted
time ✖ Frequent data migrations
ü No overprovisioning ü Less resources, less time ü Easy to change

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
Virtual Desktop (VDI) Tier 2 / Tier 3 / Staging DR Target
