SoftNAS Cloud Storage Gateway is a software-based NAS solution that is designed to provide simple but powerful file services for an Open Storage Platform infrastructure. This is an on-premises version of the SoftNAS technology that’s used by cloud service providers to create a high-performance NAS software layer running in AWS or on local object storage systems.
SoftNAS runs as a VM on the VMware ESX hypervisor, creating storage pools with VSAN (embedded in VMware) from available storage media and serves up files via NFS, CIFS/SMB or AFP (Apple File Protocol). In addition to storage devices internal to each host, SoftNAS can use DAS, SAN (iSCSI) and available object storage systems via S3, with integration provided for NetApp, StorageGrid and HDS.
The Cloud Storage Gateway can also access storage capacity in the public cloud including AWS, Azure, CenturyLink, etc. and use its cloud- based technologies to efficiently create storage pools from which to provide shared file services.
SoftNAS is based on the ZFS (Linux CentOS) open-source file system which, when combined with VSAN, brings a number of advanced features and functionality to the product. These include local and remote replication, in-line deduplication and compression, writable snapshots, clones and thin provisioning. Also included is WAN optimization, from the SoftNAS technology foundation in cloud based NAS services. This technology can produce WAN bandwidth usage rates greater than 98% in many circumstances, according to the company.
