Cloud Storage Gateway

It uses OSS for cloud-based storage at the back end, and supports industry standard file and block storage protocols.

Cloud Storage Gateway is a gateway service that can be deployed on your on-premises data center or in the cloud. It uses Alibaba Cloud OSS as the backend storage to provide seamless, secure integration between your organization's internal IT environment and your cloud-based storage infrastructure. It supports industry-standard storage protocols (NFS/SMB/iSCSI) and provides low latency performance by caching frequently accessed data locally. You can securely store data in Alibaba Cloud OSS.

Benefits

Flexible Deployment
You can deploy Cloud Storage Gateway in both local data centers and ECS instances in the cloud.
Fast Deployment and Use
Use Cloud Storage Gateway immediately with simple deployment that does not require code.
High Performance
You get Imput/Output (I/O) performance similar to a local disk coupled with the scalability of cloud storage.
Protocol Conversion
File protocols such as NFS and CIFS and iSCSI block protocols are all available and based on the same protocols in OSS.

Features

Smart and High-performance Caching

Cloud Storage Gateway offers local and flexible caching enabling you to smoothly synchronize data to the cloud. Multi-threading and asynchronous operations enable high input/output performance.

Flexible Configuration

Cloud Storage Gateway supports both cache and system write through modes. You can save data in the local cache or directly to the cloud. 

Automated Storage Tiering

In cache mode, your data is automatically stored in a local storage tiers or cloud tiers based on the data usage frequency.

Cross-platform Support

Cloud Storage Gateway supports NFS, CIFS, and iSCSI storage protocols. It also supports various deployment models, including deploy the gateway in ECS instances, Hyper-V, Kernel Virtual Machine (KVM), and VMware virtual machines.

Deployment Methods

Cloud Storage Gateway supports to be deployed on a virtual machine using VMware, VHD, Qcow2, and Raw virtual machine images. It can also be deployed on ECS instances.

Highly compatible with common file storage protocols and block storage protocols

Cloud Storage Gateway supports the NFS, CIFS, and iSCSI storage protocols. It is fully adapted to both Windows and Linux. 

High efficiency Data Transfer and Validation

Cloud Storage Gateway synchronizes data using multi-threading with asynchronous pattern operations, and provides an automatic consistency check.

Efficiency

Cloud Storage Gateway supports data synchronization using multi-threading and asynchronous pattern operations to enable broken-point continuously-transferring.

Consistency

Cloud Storage Gateway automatically ensures data consistency based on the MD5 algorithm.

Robust Logging and Monitoring System

Cloud Storage Gateway provides full logs and monitoring metrics to record all activities between the storage gateway and the cloud.

End-to-end Monitoring

Cloud Storage Gateway logs all activities between the storage gateway and Object Storage Service (OSS).
