+ IBM Cloud Overview

QuantaStor 5 SDS on Bare Metal servers delivers new levels of agility to IT organizations seeking dedicated, highly-secure and hyper-scale storage across the IBM Cloud. Featuring unified file, block and object protocol support, and unique grid management technology, QuantaStor storage appliances address a broad set of workloads including server virtualization, big data, cloud backup, media editing, deep archive, and high-performance compute applications. QuantaStor 5 is designed, integrated and certified for use with all Mass Storage Servers in IBM Cloud datacenters worldwide

Solutions

QuantaStorSAN/NAS servers provided block (iSCSI) and file (NFS/SMB) storage for a wide variety of use cases including server virtualization, data analytics, backup storage and databases/OLTP. Hybrid configurations leverage a combination of HDDs and SSDs to provide fast and reliable, storage with cost-efficient IBM Bare Metal hardware.

• SAN/NAS Storage Servers

QuantaStor Scale-Out storage clusters provide block and S3 compatible object storage using erasure-coding and replica based data distribution technology to achieve high-availability and fault-tolerance.

• Scale-out Block Storage Cluster

• Scale-out Object Storage Cluster

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.

• NAS Gateway Appliance

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.

• Scale-out NAS Archive Storage

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.
