NexGen Storage Introductory Presentation

Take control of storage performance

Have You Ever…

Performance

Had to add more disk drives, even though you already have too much capacity?

Decided not to run an application on your storage system to avoid pushing performance off a cliff?

Implemented a new storage infrastructure to isolate a workload from existing applications?

Excess Capacity

Excess Performance

There’s No Way to Manage Storage Performance

Solid-stateSize by capacity = excess performance

Disk DrivesSize by performance= excess capacity

TieringAdds complexity

• Performance is configured, not managed

• Forces you to buy resources you don’t need

• Every workload impacts every other workload

• There’s no way to predict performance

• Getting it wrong is expensive and painful

ComplexUnpredictable

Forget What You Know

• Guarantee performance for applications with:

- Quality of Service

- Service Levels

• Higher storage efficiency with:

- PCIe Solid-state minimizes the performance footprint

- Dynamic Data Placement provides best price-performance

- Data Reduction reduces system $/GB

PCIe Solid-state Is More Efficient

Solid-state behind SASDesigned for high latency disk drives

Lower CapacityLimited Performance

Maximum CapacityMaximum Performance

Solid-state on PCIeDesigned for CPU and RAM, extreme low latency

Leveraging Solid-State for Every Workload

11

Tier

• Application sends a block write IOP

• The data block is mirrored

- Data exists on two PCIe solid-state devices

- Data is in a highly available state

• The block write IOP is acknowledged

Cache (Writes and Reads)

• The redundant copy is moved to disk

• Original copy in solid-state used for writes/reads

Processor/PCIe Solid-State Offline

• Data is rebuilt using redundant copy

Archive

• Original copy evicted from solid-state

• Infrequently accessed blocks stored on disk
