Panasas Launches ActiveStor 18

Today Panasas introduced its new hybrid scale-out NAS appliance, ActiveStor 18. The ActiveStor 18 is scalable over 20PB and has speeds of 200GB/s. This is a big increase from ActiveStor 16 that topped out at 12PB and 150GB/s. ActiveStor 18 also offers increased CPU power and twice the storage cache capacity.

ActiveStor 18 delivers performance and data protection that increases with scale. By combining high-capacity HDD (8TB now) and fast SSD gives users superior mixed-workload performance with rapid access to small and large files alike. ActiveStor 18 is designed to accelerate time-to-results for the most demanding high performance workloads in energy, government, life sciences, manufacturing, media and entertainment, and university environments. ActiveStor 18 is a fully integrated solution offing true scale-out architecture incorporating hybrid storage hardware, file system, and protocols.

Key Features of ActiveStor 18:

  • Linear scalability of capacity and performance
  • Field proven at more than 20PB and 200GB/s in a single global namespace with 130 shelves, 2,600 HDDs, 1,300 SSDs
  • 33% increase in density
  • Up to 1.8PB per rack (or 181.2TB per 4U enclosure), leveraging 8TB drive technology
  • Flash capacity optimized for RAID 6+ triple parity data protection
  • Up to 20% faster mixed workload, metadata and small file performance
  • 2x more storage cache – up to 2.7TB per rack (or 272GB per 4U enclosure)
