What is NuvolaStack?

Maximize your ROI in information technology and supercharge your current IT infrastructure at a FRACTION of the cost of replacing it

NuvolaStack Software Defined Storage (SDS) is an NVMe-oF and RDMA storage subsystem solution for transportation of large amount of data in physical, logical volumes and data centre infrastructure.  It is a powerful and necessary tool for deployment of computing storage and backup for on-premise data protection and for publicly/privately hosted cloud.

Key Features

Protocol

  • iSCSI (TCP)
  • iSER (iSCSI over RDMA, InfiniBand, RoCE and iWarp)
  • NVMe over Fabric (NVM-oF, InfiniBand, RoCE and iWarp)
  • High Availability for All above
  • Storage Stack Features

Storage Stack Features

  • Strong Consistency
  • Unlimited Snapshots
  • Zero-Copy Snapshots
  • Multi-Copies or RAID5
  • Completely Kernel-Bypass
  • Zero System Call in I/O path
  • RAW and Log Structured Volume
  • All Flash and Hybrid Storage Pool
  • Polling Mode, Zero Context Switch

Data Safety

  • Strong Consistency, I/Os return back after safely placed in the DISKs
  • Multiple Copies, SDS model or RAID model
  • Manage multiple disks in RAID mode: RAID-0, RAID-1, RAID-5
  • Remote replication or High Availability
  • Supports two nodes (or more) High-Availability (HA) feature for all interfaces:
    • iSCSI, through TCP
    • iSER, through RDMA (InfiniBand, RoCE and iWarp)
    • NVMe-oF, through RDMA (InfiniBand, RoCE and iWarp)

 

 

Functionality and Performance

  • 2,000,000 IOPS per Volume
  • 6,000,000 IOPS per Server
  • High Optimized for all flash array
  • Hybrid storage compatible with SATA&SAS SSD/HDD

  • Simultaneous use of 1-2 NVMe to get the benefits of the kernel-by-pass performance
  • Bind to a fixed CPU core and working in polling mode, zero locking and zero system call
  • Listen on different ports to provide iSCSI, iSER and NVMF
  • Manage multiple disks in RAID mode: RAID0, 1 and 5
  • Strong Consistency, I/Os return after they are safely placed on DISKs
  • Multiple Copies , SDS model or RAID model
  • Remote replication or High Availability
  • RDMA support to provide user space NVMe driver to access NVMe device by-pass the kernel
