Description of instance specifications

Specification Description
Local storage Local storage, also called cache disks or local disks, refers to the disks attached to the physical servers where ECS instances are hosted. Local storage provides temporary block storage for instances. Local storage capacity is measured in GiB. Data stored on local disks may be lost when the compute resources (vCPUs and memory) of an instance are released or when an instance is failed over to a normal physical server upon a physical server failure. For more information, see Local disks.
Bandwidth The maximum sum of inbound and outbound bandwidth.
Note Each instance specification is verified and obtained in a test environment. In actual scenarios, the performance of an instance may vary based on other factors such as instance load. We recommend that you perform business stress tests on instances to choose appropriate instance types.
Packet forwarding rate The maximum sum of inbound and outbound packet forwarding rates. For information about how to test the packet forwarding rate, see Test network performance.
Note Each instance specification is verified and obtained in a test environment. In actual scenarios, the performance of an instance may vary based on other factors such as instance load and image version. We recommend that you perform business stress tests on instances to choose appropriate instance types.
Connections Connections, also called sessions, are the process of establishing connections and transferring data between a client and a server. A connection is uniquely defined by the network communication quintuple that consists of a source IP address, a destination IP address, a source port, a destination port, and a protocol. Connections of an ECS instance include TCP, UDP, and ICMP connections.
NIC queues The maximum number of NIC queues that the primary NIC of an instance supports. If your instance type is not a member of an ECS Bare Metal Instance family, the maximum number of NIC queues supported by a secondary NIC is the same as that supported by the primary NIC.
