• FUSE File System Support
• Big File File System to mount OX as a single big file
• Several bug fixes to improve performance

OX Controller v2.6

This version contains:
-> Open-channel SSD v1.2 abstraction (bottom layer)
-> OX-App Framework (for application-specific FTL development)
-> OX-Block FTL (NVMe block device)
-> OX NVMe over Fabrics implementation
-> OX Host NVMe user-space library (nvme-host.h)

This version runs in ARM, x86, and any other machine with a Linux environment.

OX Controller v1.4.0

This release contains new functionalities and bug fixes.

New functionalities include:

• pblk support (LightNVM host-side FTL and file systems on top of the DFC equipped with OX);
• Single sector reads;
• Per sector OOB data transfer;
• Multi-channel I/O commands;
• Runtime command line;
  • Enable/disable debug without restarting OX;
  • Show queues status at runtime;
• Create bad block table as admin command;
• Three types of bad block table creation;
  • Emergency table;
  • Fast scan (erase blocks);
  • Full scan (erase, write full, read full, compare buffers);
• NAND level reset in case of timeout (FPGA is stuck);
• Controller level reset in case of nvme timeout (host reset);

OX Controller v1.3

This release enables the FPGA 03.01.00 version.

Maximum bandwidth:
READ : ~385 MB/s
WRITE: ~298 MB/s

This release also maintains a non-volatile bad block table into NVM.
