Solutions
QuantaStor NAS gateway appliances can be configured to periodically back-up local NAS storage to IBM Cloud Object Storage as objects or cache metadata as a pure NAS pass-thru gateway to IBM Cloud Object Storage.
QuantaStor scale-out NAS Archive configurations provide highly-available file storage suitablearchive applications with lower performance requirements. SSD is added to each appliance to accelerate write performance and each NAS Archive cluster must contain a minimum of 3x appliances.
QuantaStor Software Defined Storage appliances are designed with high-availability and scale-out features needed for mission-critical desktop and server virtualization solutions. QuantaStor storage servers provide VMware certified NFS and iSCSI storage with advanced features including encryption, compression, and remote-replication.
Deployment
The QuantaStor Provisioning Guide provides easy-to-follow instructions for the optimal configuration and set up of your QuantaStor solutions in the IBM Cloud. The Guide includes reference configurations for each of the QuantaStor 5 on IBM Cloud Bare Metal solutions, including SAN/NAS Appliances, Scale-out Block & Object appliances and NAS Gateway appliances.
