| 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 SAN/NAS Storage Appliance Features
- Provides NFS, SMB and iSCSI storage
- Compression, AES 256 bit Encryption
- Remote-replication between QuantaStor appliances across IBM data centers and on-premises locations for hybrid cloud.
- Snapshot Schedules with long term snapshot retention options.
- Hybrid SSD+HDD configuration provide economical capacity with performance
- All-Flash configurations deliver maximum IOPS
- Easy web-based management with Storage Grid technology
- NIST 800-53, HIPAA, CJIS compliant
- FIPS 140-2 Level 1 compliant options available Q4/18
- Advanced Role Based Access Controls
- Automatable via QS CLI and REST API
- VMware certified and VMware VAAI integrated
| 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 are 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.

| TECHNICAL SPECIFICATIONS |
QuantaStor SAN/NAS Storage Appliances
| 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. |
Select the OSNEXUS operating system QuantaStor license tier based on the amount of raw storage capacity. License, maintenance, upgrades, and support included. |
