NVMStack is software defined storage (SDS) solution that creates user mode, software RAID (0, 1, 5) pool over multiple NVMes, and enables user to create RAID-0, 1, 5 volume to be exported over iSCSI, iSER or NVMe over Fabrics.
The NVMStack RAID pool are based on NVMStack kernel-bypass, zero-lock stack, that deliveries a low cost redundant solutions on local NVMe devices.
Except NVMe devices, the NVMStack RAID pool also support traditional storage devices like SATA/SAS SSD/HDD.
We have designed advanced software technology to leverage productive work with NVMe that enables to utilize up to 98% of hardware performance capabilities. Such results comes from high I/O handling parallelization and lockless data-path.
This technology is embodied in NVMStack software, the NVMe-RAID technology delivers the following features:
1.Complete user mode polling, zero-lock, zero-context-switch, zero-copy
2.Exporting logical volume over iSCSI, iSER or NVMe-of
3.Back-end could be local NVMe, local SATA/SAS SSD/HDD or remote NVMe-oF device.
