Elastic Volume Service (EVS) disks EVS provides storage space for FlexusL instances. Cloud Backup and Recovery (CBR) vaults You can use CBR to back up all EVS disks (including system and data disks) and restore data from backups.
EVS Disks Table 4 Restrictions on EVS disks of FlexusL instances Item Description System disk Only General Purpose SSD disks are supported. System disks cannot be added. An existing system disk cannot be attached. System disks cannot be expanded separately.
After this API is called, all resources including the EVS disks, cloud backup vault, HSS, and EIP associated with the FlexusL instance will be unsubscribed from. When unsubscribing from an in-use resource, confirm the resource and refund information carefully.
Constraints N/A Range evs indicates data disks. cbr indicates cloud backups. hss indicates host security. Default Value N/A size No Int Definition Capacity of the resources whose type is evs or cbr. Constraints This parameter is not involved for the hss resource type.
Overview Elastic Volume Service (EVS) provides scalable block storage that features high reliability, high performance, and a variety of specifications for cloud servers. An EVS disk can be used as a system disk or a data disk.
EVS Monitoring EVS monitoring collects metrics of EVS disks every 5 minutes on average. For details, see Viewing EVS Monitoring Data. CBR Monitoring CBR monitoring collects metrics of the used vault size and vault usage of CBR every 15 minutes.
If you unsubscribe from a FlexusL instance, all resources including the EVS disks, cloud backup vault, HSS, and EIP associated with the instance will be released and data cannot be recovered.
API Overview A FlexusL instance is a package of resources that include cloud servers, EIPs, EVS disks, CBR vaults, and HSS. Cloud servers are servers in a FlexusL instance. This section describes some common APIs of FlexusL instances.
A FlexusL instance is a package of resources that include cloud servers, EVS disks, EIPs, CBR vaults, and HSS. Resources in the package are created and managed as a whole. FlexusL instances provide various images to help you quickly set up service environments.
A FlexusL instance is a package of resources that include cloud servers, EVS disks, CBR vaults, and HSS. FlexusL instances are sold and managed as packages.
