Billing

SMS is free, but you are billed at standard rates for EVS disks, EVS disk snapshots, and data transfer during the migration process.

  • EVS disk

    SMS creates and attaches a 40-GB EVS disk to each target server temporarily during the migration. These EVS disks are billed on a pay-per-use basis. After the migration is complete, these EVS disks will be released. Do not delete these EVS disks during the migration or change their billing modes to yearly/monthly, or the migration will fail.

    For pricing details about EVS, see EVS Pricing Details.

    For example, if a 40-GB high I/O EVS disk with the unit price of $0.0002 USD/GB-hour is used for 10 hours during migration, the EVS disk price is $0.08 USD (0.0002 x 40 x 10).

  • EVS disk snapshot

    SMS creates snapshots for service cutover, data synchronization, and cloning target servers. For details about these snapshots for of target servers, see What Are the Snapshots of a Target Server Used for?

    EVS snapshots are free. For more information, see EVS Snapshot.

  • Data traffic

    Traffic is generated during the migration and is billed as follows:

    • If the source public IP address is billed by bandwidth and you use the fixed bandwidth for migration over the Internet, the traffic you used will not be billed.
    • If the source public IP address is billed by traffic and you migrate data over the Internet, the price is calculated by multiplying the unit price of traffic by the amount of data migrated. For details about the unit price of traffic, contact the provider of the source public IP address. The amount of data migrated is the actual usage of disks on source servers.

      If the public IP address is billed by traffic, the unit price is $0.15 USD/GB, and the total disk size of a source server is 500 GB (including 300 GB of used space), the cost is $45 USD (0.15 x 300). Note that this fee is charged by the provider of the source public IP address.

    • If you use Direct Connect or Virtual Private Network (VPN) for migration, the cost depends on the price of your Direct Connect or VPN connections.

      The preceding fees are for reference only. The actual fees may vary.
