  • CSG can be integrated with CloudMonitor.
  • The upload performance of big files in file gateways is improved.
  • CSG allows you to pay for network bandwidth upgrades.
Available in the following new regions:
  • Malaysia (Kuala Lumpur)
  • US (Silicon Valley)
  • US (Virginia)
v1.2.0 January 8, 2020 New features:
  • File gateways of the Enhanced and Advanced models support disk encryption by using a bring-your-own-key (BYOK) solution. This feature is available only to selected users.
  • File gateways allow you to associate multiple OSS buckets with the same share.
Associate a share with multiple OSS buckets
Optimization of user experience:
  • File gateways support fragment optimization by using the Network File System version 4 (NFSv4) protocol. If multiple requests for to upload a file to the OSS bucket are sent, the request is processed only once. File gateways cannot mount shares to local clients over NFSv3.
  • The express synchronization feature is optimized on the NFS client side. Metadata updates can be discovered by NFS clients in time.
v1.1.0 December 26, 2019 New features:
  • File gateways support express synchronization. This feature detects data changes in OSS buckets without the need for a full scan. Express synchronization allows a single user to write data to and multiple users to read data from the same gateway at the same time.
  • File gateways support Windows access-based enumeration (ABE). Together with the Active Directory (AD) service, this feature can separate access requests from different accounts.
Optimization of user experience:
  • The specification of CSG can be upgraded.
  • CSG supports automatic renewal of subscriptions.
Available in the following new regions:
  • China (Chengdu)
  • Indonesia (Jakarta)
