Key Features

QuantaStor’s scale-out object configurations provide S3 and SWIFT compatible REST API support. Configurations scale-out by adding additional drives and appliances. Each appliance contains SSD to accelerate write performance and each cluster must contain a minimum of 3x appliances and a maximum of 32s appliances (10PB maximum). QuantaStor’s storage grid technology enables appliances to be grouped together and managed as a storage grid which can spans IBM datacenters. Within a storage grid one or more object storage clusters may be provisioned and managed from QuantaStor’s web based management interface as well as via QS REST APIs and the QS CLI.

QuantaStor Scale-out Object Storage

  • 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 is 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 depending on object size and number of concurrent client connections. Erasure-coding is recommended for best write performance and replica mode is recommended for best read performance. Each appliance can present S3 access to object storage and load balancing of client connections across the appliances can be done in a variety of ways including round-robin DNS.

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: Storage Management Tab → Modify Storage System → Set Domain Suffix → Click OK (do this for each appliance)
Step Six: Scale-out Object Storage Tab → Create Ceph Cluster → Select all appliances → Click OK
Step Seven: Scale-out Object Storage Tab → Multi-Create OSDs → Select SSDs as journals, HDDs as OSDs → Click OK
Step Eight: Scale-out Object Storage Tab → Create Object Storage Pool Group → Select Erasure Coding Mode → Click OK
