Why do we dedicate storage for applications?


Why we have dedicated storage for VDI

•Discovering how to integrate into existing infrastructure is very difficult

•Unpredictable and volatile VDI workloads (boot storm, patches)

•Inability to guarantee acceptable user experience

•Difficulty scaling existing storage assets from pilot/POC to production

•Scale-up storage model does not enable elastic scaling

•Complex desktop management & scheduled maintenance requirements for VDI

The SolidFire Advantage


Adaptable Infrastructure

•Go from pilot to production and beyond

•Design for X and change to Y on the fly

•Adjust QoS controls to accommodate boot storms, virus scans, patching and recompose operations

•Share storage infrastructure with other workloads (tenants), each with defined performance parameters


Eliminate Storage Sprawl

•Extremely dense deployment with 1000+ desktops per node keeps footprint small

•Collapse multiple application silos to a true shared storage infrastructure

•Fined grained QoS allows mixing of disparate workloads without fear of noisy neighbor issues


Granular Scalability•Incrementally add nodes to increase total IOPS and capacity available to desktop pools

•Logically scale existing volumes to increase performance and capacity on demand

•No forklift replacements when desktop capacity is out grown

•No downtime required to scale environment


Simplified VDI Administration

•Provisioning storage to the broker software is as simple as “how much?” and “how fast?”

•Speed up desktop provisioning and maintenance

•Automatically balance desktop workload across the entire system eliminating hot spots

•Self-healing eliminates fire drills from failures

•SolidFire rolling upgrades do not mandate outage window -> critical for mixed workload / multitenant environments


Lowest $ per Desktop

•Inline data efficiency means all desktop profiles are cost effective

•VDI storage costs under $50 / desktop

•Less than $1 per desktop IO

•Fit 1,000+ desktops per node = optimal data center footprint
