NAS Gateway - WIP

QuantaStor’s NAS Gateway Storage System can be configured to have local NAS storage which is periodically backed-up to IBM Cloud Storage as objects or alternatively can be configured to cache a quantity of metadata but otherwise can serve as a NAS pass-thru gateway to IBM Cloud Storage.

Key Features

• Provides NFS, CIFS and SMB access to IBM S3 Object Storage
• Objects map one-to-one as Files and vice-versa
• Backup Policies feature performs backups of file shares to IBM S3 Object Storage
• Snapshot Schedules with long term snapshot retention options make file recovery from system local Network Shares easy.
• Automatize operations via QS CLI and REST API

Quick Configuration Steps

Step One: Cloud Containers Tab → Cloud Storage Providers → Add Credentials → select Softlayer S3, enter keys → Click OK
Step Two: Cloud Containers Tab → Cloud Storage Containers → Cloud Container Create → enter share name → Click OK
Step Three: Storage Management Tab → Network Shares → Modify Network Share & SMB Access → adjust settings → Click OK

Performance

NAS Gateway based Network Shares are not for high-performance use cases and will typically see 50MB/sec with 1GbE uplinks. If higher performance is required then a system local Network Share should be provisioned which is backed up to a cloud-based Network Share using a Backup Policy. The performance of an system local Network Share is limited to the number of disks in the storage pool and can deliver over 1.2GB/sec of read/write throughput for large files on systems configured with dual 10GbE.
