Notes on using gateways deployed on Alibaba Cloud

Last Updated: Jun 28, 2019

1.The Alibaba Cloud CSG console supports HTTPS. NFS and SMB require specific ports. You must open these ports in the firewall or security group.

Notes:

1.Version 1.0.32 and later support AD and LDAP. You need to configure ports for these services: AD, LDAP, DNS, and Kerberos. You can configure ports by using the following methods:

Specify CIDR blocks.

Authorize security groups. Under the same VPC network and account, you can authorize a security group to another security group. For example, authorize the gateway security group to the security group of the domain server. Add the following rules to the security group of the domain server: TCP 53/636 and UDP 53/636.

For more information about these methods, see https://help.aliyun.com/document_detail/25471.html .

2.Ports required by NFS and SMB need to be configured in the security group that controls inbound network traffic. After a gateway is deployed on Alibaba Cloud, these ports are automatically configured in the security group. You need to configure AD and LDAP for ports that control inbound network traffic in the security group of the domain server.

2.The preview version allows you to create one Enhanced gateway, two Standard gateways, and four Basic gateways under each Alibaba Cloud account. This limit applies to all gateway specifications. Only whitelisted users can create Performance gateways.

3.During the preview stage, the cache disk capacity that you can add for gateways with versions earlier than 1.0.35 are determined by the gateway specification. Version 1.0.35 and later allow you to add cache disks with custom capacities in the Alibaba Cloud CSG console(<8192GB).

Basic: 50 GB.

Standard: 100 GB.

Enhanced and Performance: 200 GB.

After the 1.0.35 version, the newly created gateway no longer comes with the default cache. You need to manually add the cache disk in the Alibaba Cloud CSG console.

4.The synchronization bandwidth of a gateway is determined by the OSS bandwidth. Currently, OSS provides a maximum bandwidth of 10 Gbit/s. The bandwidth of an OSS cluster varies depending on the region. For more information, consult Alibaba Cloud customer service.

5.After a gateway is created, a security group prefixed with Cloud_Storage_Gateway_Usage is created by default. Do not use this security group when you create ECS instances.

6.When the number of files stored in the OSS bucket reaches one million, we recommend that you specify an interval longer than 3,600 seconds for the Enable Remote Sync feature.

7.Version 1.0.36 and later automatically specify a MIME type in the OSS metadata based on the file suffix.

8.When the Enable Remote Sync parameter is set to Yes, local empty directories that are not uploaded to Alibaba Cloud may be deleted by the Remote Sync progress during a scanning cycle. You can solve this issue by creating the directories again.

9.By default, the upload bandwidth of gateways deployed on Alibaba Cloud is 5 Mbit/s. These gateways access OSS buckets across regions through their public IP addresses. The data transmission quality and speed cannot be guaranteed.
