THE DATA STORAGE SHORTFALL

Data stores are growing exponentially, while IT budgets are not

HDDs are becoming more dense, but $/GB decline is slowing

Software and hardware advances are needed to close the gap

70% of IT decision makers admit that their organization’s

current storage can’t cope with

emerging workloads

98% of IT decision makers believe a more agile storage solution could benefit their organization

SAN/NAS IS ON THE DECLINE

• Storage capacity shipped inside servers has grown since 2010, and is now the majority

• Capacity shipped in SAN/NAS is declining, reflecting the use of server-based storage technologies by web-scale firms

Changing workloads drive the need for flexible, economical server-based storage.

WHY THIS MATTERS

PROPRIETARYHARDWARE

Common,off-the-shelf hardware

Lower cost, standardized supply chain

18

INDUSTRY STANDARD HARDWAREStandardization makes storage more convenientCustomers can build clusters using standard hardware from existing vendors that’s perfect for their workload.

• Clusters can be performance-optimized, capacity-optimized, or throughput-optimized

• Need capacity? Add more disks. Too slow? Add more servers.

• Clusters can become larger or smaller with no downtime

WHY THIS MATTERS

20

PERFORMANCE THAT SCALESPerformance should scale up as capacity does

Software-defined storage intelligently uses hardware to provide performance at very large scale.

• Traditional appliances perform better when they are empty than they do when they are full of disks

• Performance in software-defined storage clusters improves as clusters get larger, not the other way around

• Intel, SanDisk, Fujitsu, and Mellanox regularly contribute performance optimizations

THE ROBUSTNESS OF SOFTWARESoftware can do things hardware can’t

Storage services based on software are more flexible than hardware-based implementations

• Can be deployed on bare metal, inside containers, inside VMs, or in the public cloud

• Can deploy on a single server, or thousands, and can be upgraded and reconfigured on the fly

• Grows and shrinks programmatically to meet changing demands
