THE SOFTWARE DEFINED STORAGE LITMUS TEST

HARDWARE

INNOVATION

• Can I repurpose existing industry-standard servers as storage servers rather than buy new

hardware?

• Can I run my storage clusters on a heterogeneous mix of server brands?

OPERATING

EXPENSES

• Can innovations in storage controller software be delivered independently from hardware

upgrades?

• Am I limited by my vendor’s ability to validate new storage features and hardware advances?

• Can I grow my storage cluster in small increments (e.g., by a few servers at a time) or am I

limited to the increments defined by the vendor (e.g., quarter, half or full rack)?
