 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

 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 to expand capacity. Additional appliances may be added to a given storage grid for easy management of all appliances across IBM data centers. OSNEXUS recommends provisioning a 24 bay or 36 bay server with
free drive bays available for expandability as expansion disk-enclosures are not available as an add-on
except at the time of initial server/appliance deployment.

 EXPECTED PERFORMANCE

Each appliance is configured with at least one storage pool and each pool will deliver 400MB to 1.6GB/sec sequential throughput depending on block size and number of disks. IOPS are increased through the use of mirrored SSD storage
configured as a write log which in turn will increase IOPS to 10K to 20K depending on block size and access patterns. All-Flash configurations will deliver over 100K sustained R/W IOPS.

 QUICK CONFIGURATION STEPS

Step One: Storage Management Tab → Controllers & Enclosures → Right-click Controller → Configure Pass-thru devices → Select all → Click OK
Step Two: Storage Management Tab → Storage Pools → Create Storage Pool → Click OK

For iSCSI Block Storage Provisioning:

  • Storage Management Tab → Hosts → Add Host → Enter host IQN → Click OK (do this for each host)
  • Storage Management Tab → Storage Volumes → Create Storage Volume → Enter volume name, select a size, → Click OK
  • Storage Management Tab → Hosts → Right-click Host → Assign Volumes → Select volumes → Click OK

For NFS/SMB File Storage Provisioning:

  • Storage Management Tab → Network Shares → Create Network Share → Click OK (do this for each share)
  • Storage Management Tab → Network Shares → Modify Network Share & SMB Access → Adjust Settings → Click OK (do this for each share)

OSNEXUS QuantaStor Scale-out iSCSI Block Storage



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.
