Cloud Storage Gateway

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

Activate Service Contact Sales

Cloud Storage Gateway is a gateway service that you can deploy on the premises or in the cloud. This service provides a seamless and secure connection between your on-premises IT infrastructure and cloud-based storage services at the back end, such as Alibaba Cloud Object Storage Service (OSS). Cloud Storage Gateway supports standard storage protocols in the industry, such as NFS, SMB, and iSCSI, and locally caches frequently accessed data to achieve low latency in data access. Based on Cloud Storage Gateway, 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.
Out-of-box experience
You can use Cloud Storage Gateway immediately with simple deployment that does not require writing code.
Fast and Scalable
Get the speed and convenience of local storage, with the scalability and reliability of the cloud.
Protocol conversion
The NFS and CIFS file protocols, and the iSCSI block protocol are available. These protocols are based on OSS.

Features

Intelligent high-performance caching

Cloud Storage Gateway offers a local cache mode and flexible caching policies. You can smoothly synchronize data to the cloud. Multi-threading and asynchronous operations enable high input/output performance.

Flexible configuration

Cloud Storage Gateway supports both cache mode and write-through mode. You can save data in the local cache to later synchronize to the cloud, or directly write data to the cloud. 

Automated storage tiering

In cache mode, your data is automatically stored in a local storage tier or cloud tier 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-based Virtual Machine (KVM), and VMware virtual machines.

Various 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 of data transmission and validation

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

High 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 various 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).
