• 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…

Lossless Network Fabric is IMPORTANT

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
