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.
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.
