This topic describes all phased-out instance types on the China site (aliyun.com). However, the instance types sn1, sn2, n1, n2 and e3 are still available for purchase on the International site (alibabacloud.com).
Specifications
- The packet forwarding rate refers to the maximum sum of inbound and outbound packet forwarding rates. For more information about how to test the packet forwarding rate, see Test network performance.
- NIC queues refer to the maximum number of NIC queues supported by the current instance type. By default, the CentOS 7.3 image uses the maximum number of NIC queues.
- Enterprise-level instance types that are equipped with two or more vCPUs support Elastic Network Interfaces (ENIs). Entry-level instance types that are equipped with four or more vCPUs support ENIs. For more information about ENIs, see ENI overview.
Instance type upgrade
For information about the phased-out instance types that can be upgraded to newer instance types, see Instance families that support instance type changes.
