This topic describes all phased-out instance types. These instance types are no longer available for purchase at Chinese sites. However, the instance types sn2, sn1, n1, n2, and e3 are still available for purchase at international sites.
Indicator description
- The packet forwarding rate refers to the maximum number of inbound and outbound packets that can be processed by an ECS instance. For more information, see Test network performance.
- NIC queues refer to the maximum number of NIC queues that an instance type supports. If your instance runs CentOS 7.3, the maximum number of NIC queues is used by default.
- Enterprise-level instances with two or more vCPU cores and entry-level instances with four or more vCPU cores support elastic network interfaces (ENIs). For more information, see ENI overview.
Instance configuration upgrade
Some phased-out instance type families support upgrading to a newer instance type. For more information, see Instance type families that support instance type upgrades.

Instance types of Generation I
Instance types of Generation I include t1, s1, s2, s3, m1, m2, c1, and c2. All these
instance types are legacy shared instance types. They are still categorized by the
number of cores (1, 2, 4, 8, and 16 cores) and are not sensitive to type families.
Note For information about instance type families of Generation II and Generation III,
see Instance type families.
