- 6. IBM Cloud NAS Gateway Appliance

From OSNEXUS Online Documentation Site
Jump to: navigation, search

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 some metadata but otherwise be a pure NAS pass-thru gateway to IBM Cloud Storage.

Key Features

  • Provides NFS and SMB access to IBM S3 Object Storage
  • Objects map one-to-one as Files and vice-versa
  • Backup policies enable backups of NFS/SMB shares to IBM S3 Object Storage
  • Snapshot Schedules with long term snapshot retention options make file recovery from system local Network Shares easy.
  • Automatable 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

Expandable

Since the NAS gateway based Network Shares (QuantaStor Cloud Containers) are backed by IBM Cloud Object Storage there are no local storage requirements except that the boot device should be SSD based to improve cache performance. NAS gateway to object storage is for general unstructured data and backups. Gateways cannot be used directly for database and virtualization workloads. Add additional drives to expand capacity. Additional systems may be added to a given storage grid for easy management of all systems across IBM data centers. OSNEXUS recommends provisioning a 24-bay or 36-bay server with free drive bays available for expandability as expansion disk-enclosures are not available as an add-on except at the time of initial server/system deployment.

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 an system local Network Share should be provisioned which is then 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.
