SCVM (Storage Controller Virtual Machine) is a virtual machine used to install ACOS when ACOS is deployed with VMware ESXi in a hyperconverged form.
The availability zone where services are recovered when exceptions occur and recovery is not possible in the primary availability zone of the ACOS active-active cluster.
One of the default roles provided by AOC, which has the permission to view event audits.
A group that logically groups resources such as virtual machines, IP addresses, or pods with the same security requirements. Through a uniformly configured security policy, it implements centralized control over the ingress and egress traffic of group members.
Applies a three-stage architecture, which allows flexible definition of ingress and egress allowlists and blocklists for different policy objects (such as security groups, virtual machines, or global traffic), achieving fine-grained control and secure isolation of east-west traffic.
Provides services for applications, receives and responds to requests distributed by the load balancer.
Multiple connections from the same user within a period of time are directed to the same backend host without load balancing. Network load balancer will perform session persistence based on the source IP, meaning that sessions from the same client IP are all sent to the same backend server.
In backup and disaster recovery scenarios，the site is a failure domain managed by a single AOC instance, which can include one or more clusters and data centers. Sites are logically and physically isolated from each other.
In cross-platform virtual machine migration scenarios, the site refers to the source or destination management platform or cluster hosting the virtual machines.
SMTP (Simple Mail Transfer Protocol) is a protocol for transmitting emails over a network.
A dedicated system that follows the SMTP protocol (RFC 5321 standard), responsible for handling the sending, relaying, and delivery of email messages. It establishes a reliable transmission channel between the email client and the recipient server. Port 25 or 587 is typically used.
A feature that records and saves the state of a virtual machine at a specific point in time, which can be used for data rollback.
A collection of snapshots generated after executing a snapshot plan.
Resources protected by the snapshot plan.
A policy for automating the creation and retention of snapshots on a regular schedule.
In network load balancing, SNAT (Source Network Address Translation) automatically translates the client IP address into the local IP (LIP) address of the load balancer virtual machine after requests are received, allowing communication with the backend server without exposing the actual client address.
In VPC networking, SNAT is used for IP addresses shared within a VPC to access the external network. When an address inside a VPC needs to access the external network, the internal address initiates an active connection, and SNAT translates the private IP of the internal address to the SNAT IP.
SNMP (Simple Network Management Protocol) is a communication protocol used for managing and monitoring network devices, such as routers, switches, and servers.
The replication service associated with the source cluster, responsible for reading virtual machine data from the source cluster and transferring it to the target replication service, as well as receiving data from the target replication service and writing it back to the source cluster during failback jobs.
In backup and disaster recovery scenarios，the source site is typically the site where business workloads run. The replication service replicates the source virtual machines from the source site to the target site to achieve data consistency.
In cross-platform virtual machine migration scenarios, the source site refers to the VMware vCenter platform hosting the source virtual machines pending migration.
A hardware-based virtualization solution that virtualizes a single hardware device into multiple independent virtual devices, thereby improving performance and reducing hardware costs.
A data encryption mechanism where data is encrypted before being written to the physical disk. When reading data, the ciphertext is retrieved from the disk, decrypted, and then returned to the client.
AOC is deployed as a single virtual machine instance.
Storage class provides a way for administrators to describe the class of storage, including fields such as provisioner, parameters, and reclaimPolicy.
The network used for data exchange between nodes in a cluster.
In an ACOS cluster, it refers to a regular node that does not run the metadata service.
In a file storage cluster, it refers to a file controller that only runs the storage service.
The ACOS cluster's storage policy includes redundancy policy (multiple replicas, erasure coding), provisioning methods, striping, and the volume pinning mode.
One of the default roles provided by AOC, which has all system permissions.
A mechanism in custom security policies that sets a traffic-sending egress rule on the source and a traffic-receiving ingress rule on the target to ensure proper communication.
A dedicated system for receiving, centrally storing, and managing Syslog protocol logs sent by network devices, servers, and applications. It typically standardizes log collection and analysis via UDP port 514.
A service that runs as a virtual machine and provides management and advanced features for a cluster, such as Arcfra Operation Center (AOC), Arcfra Network Service (ANS), backup service, replication service, Arcfra File Storage (AFS) service, etc.
