Configure QuantaStor NAS Gateway Server
KEY FEATURES |
QuantaStor’s NAS gateway storage appliances 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.
QuantaStor NAS Gateway Appliance 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 appliance local Network Shares easy.
- Automatable via QS CLI and REST API
USE CASES |
- Accessing IBM Cloud Object Storage as NAS via NFS or SMB protocols
- File backups of NFS and SMB shares to IBM Cloud Object Storage
- General purposed NAS file storage which is optionally backed up to IBM Cloud Object Storage
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 appliances may be added to a given storage grid for easy management of all appliances 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/appliance deployment.
EXPECTED 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 appliance 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 appliance 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 appliances configured with dual 10GbE.
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
TECHNICAL SPECIFICATIONS |
Hardware | Networking | Licenses and Fees |
Small and Medium Tier configurations use 2RU server with 12x drive bays. Large Tier configurations use 4RU server with 24x or 36x drive bays. All configurations include mirrored boot. All Hybrid configurations include 2x 800GB SSD for write acceleration. |
2x 10GbE Private Network ports recommended for all configurations. Use LACP bonded network ports when NFS based Datastores are to be configured. |
