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)?
