Who This Solution Is For
Business Benefits
Disk economics, flash benefits
QLC DirectFlash delivers all-flash latency and reliability at a cost-per-terabyte near hybrid disk arrays.
Dense petabyte capacity
75TB QLC modules pack up to 1.5PB per rack unit, shrinking floor space and power for large data sets.
Unified operations
Identical Purity management and Evergreen lifecycle as //X and //XL simplify multi-tier estates.
Typical Business Use Cases
Tier-2 and capacity-tier consolidation
Flash-class disaster recovery and replication targets
Large database and VM repositories
Policy-based snapshots and retention
Industry Applications
Technical Overview
FlashArray//C90 R4 runs Purity//FA on dual active-active controllers populated with QLC DirectFlash Modules (with onboard NVRAM), reaching up to 8.9PB effective capacity in a 6U chassis at a 5:1 reduction ratio. Each PCIe 4.0 x16 networking port runs full line rate, supporting two ports of 100GbE, four of 25GbE, or four of 64Gb FC with NVMe/TCP.

Frequently Asked Questions
Is QLC reliable enough for production?
Yes. //C90 uses QLC DirectFlash Modules managed directly by Purity, which handles wear and data placement at the array level, delivering all-flash resiliency and Evergreen-backed support for production capacity workloads.
What workloads suit //C versus //X?
//C is built for capacity-tier and cost-sensitive data such as DR targets, large repositories, and tier-2 databases. //X and //XL serve latency-critical tier-1 workloads. Many customers run both under one Purity management plane.
How much rack space does a petabyte take?
With 75TB QLC modules, //C90 reaches roughly 1.5PB per rack unit, so multi-petabyte estates fit in a single 6U chassis with room to expand via DirectFlash shelves.
