Extreme Performance Storage Appliance

siFlash slices through the data bandwidth wall and demolishes the IOP barrier!

Architected and optimized to remove latency and improve performance on any workload, siFlash delivers the fastest random reads, writes, and networks possible. Applications always have enough IOPs when deployed on siFlash. Make tightly-coupled compute and flash an integral part of your flash strategy and eliminate bottlenecks.

siFlash can be deployed as a Storage Array or as an Application Platform:

  • Block: iSCSI/iSER, SRP, FC
  • File: NFS, SMB/ CIFS, FTP
  • Scale-out Storage: Gluster, Lustre, BeeGFS/FhGFS, Ceph
  • Big Data Compute and Storage
  • Risk Analysis
  • High Frequency Trading
  • Accelerated Database

siFlash proves to be fastest at stock tracking and market analysis:

Hyperconverged Compute and Storage

Applications run faster without I/O bottlenecks. By tightly-coupling compute and storage, siFlash provides significantly more data processing power for any workload.

Extreme Performance
siFlash provides the fastest measured sustained performance for stream and random I/O for end user applications, in market, bar none. Up to 60 GB/s sustained reads and writes, and up to 4M IOPs in 64 bay configuration.

Easily Scalable
With an entry point lower than you'd expect and densities higher than you'd imagine, there is a siFlash that meets the price, performance, and capacity you need.

System Options
Combine ultra-quick siFlash storage with larger fast storage, and you can create a system that provides excellent performance and vast backup capabilities!
