    Cloud Storage Gateway:Manage an iSCSI gateway

    Last Updated:Jan 02, 2025

    This topic describes how to use the Cloud Storage Gateway (CSG) console to manage an Internet Small Computer System Interface (iSCSI) gateway that is deployed on Alibaba Cloud. For example, you can create, rename, and delete a gateway in the CSG console.

    Prerequisites

    1. An Alibaba Cloud account is created and real-name verification for the account is complete. For more information, see Create an Alibaba Cloud account.

      Note

      We recommend that you log on to the CSG console as a RAM user. For more information, see Use RAM to implement account-based access control.

    2. CSG is activated.

      If CSG is not activated, follow the on-screen instructions in the CSG console to activate CSG.

    3. A virtual private cloud (VPC) is created in the region where you want to create the iSCSI gateway. For more information, see Create a VPC with an IPv4 CIDR block.

    4. An Elastic Compute Service (ECS) instance is created on the VPC in the region where you want to create the iSCSI gateway. For more information about how to create an ECS instance, see Create an ECS instance.

      Note

      If your on-premises host is connected to a VPC over an Express Connect circuit, you can also perform the steps by using the host.

    5. An Object Storage Service (OSS) bucket is created. For more information, see Get started by using the OSS console.

      Important

      iSCSI gateways support only Standard and Infrequent Access (IA) OSS buckets. iSCSI gateways do not support OSS buckets for which back-to-origin routing is configured.

    Create an iSCSI gateway

    1. On the Gateways page of the CSG console, click Create.

    2. In the wizard, configure parameters as described in the following table and retain default settings for other parameters.

      Configuration example

      Step

      Parameter

      Description

      Gateway Information

      Name

      Specify a name for the gateway. The name must be 1 to 60 characters in length, and can contain letters, digits, periods (.), underscores (_), and hyphens (-). It must start with a letter.

      Location

      Select Alibaba Cloud.

      Region

      Select the region in which you want to create the iSCSI gateway.

      Type

      Select iSCSI Gateway.

      Gateway Configurations

      Edition

      Select Basic, Standard, Enhanced, or Performance Optimized. For more information, see Specifications.

      VPC

      Select the VPC in which you want to deploy the gateway.

      Note

      The VPC must be the one in which your ECS instance or on-premises host is located.

      VSwitch

      Select the vSwitch that is connected to the gateway.

      Note

      • The vSwitch must be the one that is connected to your ECS instance or on-premises host.

      • If no gateway resource is available in the zone where the specified vSwitch resides, create a vSwitch in another zone.

      Billing Information

      Billing Method

      Select Pay-as-you-go or Subscription. For more information, see Billable items and billing methods.

      If you select Subscription, you are redirected to the buy page after the gateway is created. You must complete the payment before you can use the gateway. For more information, see Purchase a gateway.

      Expiration Policy

      Select an expiration policy for the gateway. You can select Switch to Pay-as-you-go or Release.

    Important

    • After you create an iSCSI gateway that is deployed on Alibaba Cloud, the system completes the deployment in 5 to 10 minutes. If the Running state is displayed in the Status column, the gateway is deployed and activated.
