Key Features

QuantaStor’s scale-out block storage configurations provide highly-available iSCSI block storage suitable for a variety of use cases. Each appliance contains SSD to accelerate write performance and each cluster must contain a minimum of 3x appliances. QuantaStor’s web-based management interface, REST APIs and QS CLI make storage provisioning and automation easy.

QuantaStor Scale-out iSCSI Block Storage Features

  • S3 & SWIFT Compatible REST API support
  • Hybrid HDD + SSD configuration to boost write performance
  • Easy web-based management of all appliances with built-in QuantaStor storage grid technology.
  • Easy expansion by adding appliances and/or drives.

Expandable

Add additional drives and/or additional appliances to expand capacity. Drives can be different sizes, appliances can have different numbers of drives but for optimal performance uniform drive count and capacities per QS server/appliance are recommended.

Performance

Adding appliances will boost performance as the configuration scales-out. Small 3x appliance configurations will deliver between 400MB/sec and 1.2GB/sec sequential throughput depending on block size and number of concurrent client connections. Erasure-coding is recommended for best write performance and replica mode is recommended for best read performance.

Quick Configuration Steps

Step One: Storage Management Tab → Create Grid → Click OK
Step Two: Storage Management Tab → Add Grid Node → Enter 2nd Appliance IP → Click OK
Step Three: Storage Management Tab → Add Grid Node → Enter 3nd Appliance IP → Click OK
Step Four: Storage Management Tab → Controllers & Enclosures → right-click Controller → Configure Pass-thru devices → Select all → Click OK (do this for each controller on each appliance)
Step Five: Cluster Resource Management → Create Site Cluster → Select All → Click OK
Step Six: Cluster Resource Management → Add Site Interface → Enter IP address for SMB/NFS Access → Click OK
Step Seven: Storage Management Tab → Storage Pool → Create Storage Pool → Create one pool (XFS type) per device per appliance
Step Eight: Scale-out File Storage Tab → Gluster Volumes → Peer Setup → Select all appliances → Click OK
Step Nine: Scale-out File Storage Tab → Gluster Volumes → Create Volume → Enter name, select all Pools and Erasure Coding mode → Click OK
Step Ten: Storage Management Tab → Network Shares → right-click share for volume → Select Modify Share & SMB Access → Adjust access settings → Click OK
