Performance Drives Productivity / Efficiencies
Improve productivity
• Linearly scalable performance to
match growth and maintain SLAs
Simplify the infrastructure
• Relentless performance supports the
concurrent workloads created and
demanded by large consolidations
Lower acquisition, support and operational costs
• Efficient performance reduces the number
of drives needed to meet demands
