• 1c Compute

• 1c Network

• 1c Storage

Ingredients

• Not all solutions are complete

• You want the fabric. You can’t hyperconverge and conveniently leave out bits

• Know what pieces your HCI solution contains before you buy…

Don’t get fooled

Adding it all up…

Scale-up Storage

HyperFlex Scale-out Storage

Lossless Network Fabric is IMPORTANT

Network IncludedSAN/LAN Not Included

We give you a choice…

Storage + Compute

Compute Only

Where’s the data live?

Striped across NodesLocal to Node

And how is it protected?

Erasure Coding

• Low performance

• High availability

• Consumes less

space

• Best choice for

archival storage

RAID

• Known performance

• Trusted high

availability

• Traditional array

business

Replication

Factor

• High performance

• High availability

• Quick rebuilds

• Best choice for

primary storage

Dedup and Compression ALWAYS

• Inline Deduplication20-30% space savings

• Inline Compression30–50% Space Savings

• No Special Hardware

• No Performance Impact
