OSNEXUS QuantaStor Scale-out iSCSI Block Storage
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.
Use Cases Highly-available block storage for virtualization (VMware, Hyper-V, XenServer) Scale-out block storage with Cinder integration for KVM based OpenStack deployments Highly-available block storage for databases
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.
Expected 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.
