Servers

A server is a server instance running on a host machine built using virtualization technology, including CPU, memory, operating system, disk, network card, and other complete virtual hardware infrastructure environment.

Servers Source.

• When the cloud management platform is docked to other platform cloud accounts, it will automatically synchronize servers on other platforms to the cloud management platform for management.
• Create server creation.

Entry: In the Cloud Management Platform, click the top left corner of navigation menu, and click “Compute/Compute/Servers” menu item in the left menu bar that pops up to enter the Servers page.

• The top right of the list will show the total number of servers and the number of servers that are running, shutdown, operation failed, and unknown.

  

• In project view, the user cannot see the list parameters belonging to the domain resources, e.g. the user cannot see the host to which the server belongs or the cloud account used in project view.

Create Servers

This feature supports the creation of one or more servers on On-premise, private cloud or public cloud platform. If the host request process is enabled in the platform, the user will initiate a ticket request for host request after configuring the new server parameters, and wait for the ticket review to complete before the automatic deployment of the server begins. If the host request process is not enabled in the platform, you can directly create a new server.

Prerequisites

• On-premise: Requires the presence of OneCloud platform hosts with enabled status in the base resources, or the cloud management platform has been docked to the VMware platform, and the VMware platform hosts with enabled status exist in the base resources.
• Private cloud: The cloud management platform is required to have imported the resources of OpenStack, ZStack or DStack cloud accounts, and the hosts belonging to the above platforms exist in the base resources in the enabled state, and the corresponding platforms have available IP subnets.
• Public cloud: The cloud management platform is required to have imported the resources of Alibaba Cloud, AWS, Azure, Huawei Cloud, Tencent Cloud or UCloud cloud account, the cloud account is enabled and the status is normal, and the corresponding platform has an available IP subnet.

Operation Entrance

• Create On-premise server: In the server page, click the “Create” button at the top of the list to enter the Create On-premise Servers page.
• Create Private Cloud server: In the Servers page, click the “Private Cloud” tab at the top, click the “Create” button at the top of the list, and enter the Create Private Cloud Servers page.
• Create Public Cloud Server: On the Server page, click the “Public Cloud” tab at the top, click the “Create” button at the top of the list to enter the Create Public Cloud Server page.

Parameters configuration

• Specify Project: Specify the project to which the server belongs when creating a new server.
• Region (On-premise, Private Cloud): Select the region and zone. You need to determine the platform to which the server belongs by region when creating a private cloud platform server.
• Name: Set the name of the server.
  • When setting the number of servers greater than 1, except for the first server name, all other server names are indicated by the name -1~N.
  • Servers and baremetal share the name space. Names are unique in the system. Creating a server in a project reports a duplicate name error because a server or baremetal with that name already exists in another project.
  • The name supports an ordered suffix placeholder #, where a # takes up a place, e.g. if the name is set to host## and the number of Servers is 2, the Servers created will be named host00 and host01. If the name is still set to host##, the names will follow the previous order, numbered in descending order.
  • The name supports expressions in the format of ${variable}, such as ${host}, then the server name is displayed as the name of the host where the server is created. For detailed description, please see Server Name Expression Example Description.
• Billing type (Public Cloud): Including postpaid, prepaid packages.
  • This model is suitable for scenarios where the demand for equipment will increase dramatically in an instant, and the price is more expensive than prepaid packages.
  • This model is suitable for scenarios where the demand for the device is relatively stable and the price is cheaper than postpaid. support checkbox auto-renewal.

    Note

    • Only Alibaba Cloud annual subscriptions support purchase by the week, and the platform will automatically select Alibaba Cloud when a week is selected.
    • The renewal period for Servers purchased on a weekly basis is one week for the Alibaba Cloud platform, one month for Servers purchased on a monthly basis, and one year for Servers purchased on an annual basis; all other platforms have a one-month renewal period. Subsequent Servers are automatically renewed before each expiration.
• Auto delete after: Set the length of time to use the new server before it expires, after the set time, the server will be deleted and put into the trash. By default, no expiration is set, user can set “1 hour”, “6 hours”, “1 day”, “3 days “, “1 week”, “1 month” or customize the length of use.

  Note

  • The public cloud only supports expiration release for pay-per-use Servers.
  • Public cloud Servers are still charged after they are placed in the trash, so if the Server is no longer in use, please clear it in the trash.
• Quantity: Set the number of servers to be created.
• Platform (On-premise): Select the platform that the server belongs to, including OneCloud and VMware.
• Region (Public Cloud): You can determine the user selectable packages by city, platform, region, and zone, and it is recommended to select the closest city, which can reduce access latency and improve access speed.

  Description

  When creating a server for a public cloud platform and selecting a city, the optional platform and region need to meet both the following conditions.

  • Have a cloud account that corresponds to the platform and the cloud account is not disabled and has a sufficient balance.
  • Have a VPC and IP subnet for the corresponding platform region.
• Cloud subscription (public cloud): Servers will be created on the public cloud platform using the specified cloud subscription. Images, VPCs, IP subnets, etc. will be filtered based on cloud subscriptions.
• CPU architecture: x86 and ARM architectures are currently supported. Only OneCloud platforms support ARM architecture, other platforms only support x86 architecture by default.
• Configure GPU: Configure GPU card for the server, after enabling this item, you also need to select the specific GPU card.
• CPU, Memory: set the specifications of the server. And you can choose the available packages according to the server specifications, etc.

  Note

  The OS image is currently filtered by the CPU architecture in the configuration.

• Configuration: Server packages are combinations of CPU and memory specifications of servers with different package prices. Among them, On-premise and private cloud packages can be maintained through the cloud management platform, and users can choose the packages of On-premise or private cloud platform when creating servers of private cloud platform. The public cloud package information is synchronized with the information on the corresponding public cloud platform.
• OS: Select the image of the server, and support to get the image from the following ways. The image drop-down list includes the image name, size, CPU architecture, partition method, boot method, and supports the selected image boot method to automatically select the following boot method.
  • Public Cloud Image: Display the public image on the corresponding public cloud platform, which is only supported by the public cloud platform and is not displayed in the image list.
  • Public Cloud Custom Image: support for selecting custom images on the specified cloud account of the corresponding public cloud platform, supported only by the public cloud platform, not displayed in the image list.
  • Private Cloud Image: Show the image on the corresponding private cloud platform, only supported by the private cloud platform. Not shown in the image list.
  • VMware Platform Image: support to select the images of specified VMware accounts on VMware platform, only supported by VMware platform. Not shown in the image list.
  • Public Image: corresponds to the public image in the list of images, which is generally the common image of the system and maintained by the administrator.
  • Custom Image: Corresponds to the custom image in the system image list, generally uploaded by the user.
  • Boot from ISO: corresponds to the ISO format image in the system image list. When selecting an ISO image file, the user is required to install the operating system for the server. supported only for OneCloud and VMware platforms.
  • Server Image: Corresponds to the server image in the server image list, supported by OneCloud platform only.
  • Server Snapshot: Corresponds to the server snapshot in the server snapshot list, supported only for OneCloud and VMware platforms.

    Description

    • When using Public Image and Custom Image on the cloud management platform when creating servers on the public cloud platform, it is recommended to use cached images since they need to be cached to the public cloud platform and may take longer to create. Cached images have a cached flag to the right of the image name.
    • For servers that install Windows OS by mounting ISO, after the installation is completed, you also need to install Virtio driver, which can be obtained from the image marketplace-ISO.
• System disk: Display and set different disk types, media, and the capacity size of the disk according to the selected package. The public cloud platform does not support setting the scheduling tab

  Note

  • Only the system disk of OneCloud platform supports viewing the media corresponding to the disk.
  • System disk size is not support for resizing when creating a server in VMware platform selecting a VMware platform image or server snapshot.
  • When creating servers in OpenStack platform, image as system disk and image storage as system disk storage are supported.
  • The public cloud platform does not support setting scheduler tags.
  • When creating servers in Tencent Cloud Platform, the system disk size must be a multiple of 10. Otherwise, the creation will fail.
  • When the operating system selects “Boot from ISO”, the disk type on the server is displayed as data disk. The disk type display does not affect the normal use of the server.
  • When setting the system disk, the system will automatically check whether the storage capacity of the selected disk type meets the demand.
    • When the remaining capacity of the corresponding storage is less than 100GB, a yellow box will remind the user. At this point, you can still create the disk successfully, but we suggest you to go to Storage - Block Storage page to add new storage or adjust storage capacity.
    • When the remaining capacity of the corresponding storage cannot meet the set system disk size, a red box will be displayed and the user will be prompted to go to Storage - Block Storage page to add new storage or adjust the storage capacity.
  • When the scheduler tag and scheduling preferences are not set and block storage is specified, the system will automatically select the optimal storage for the server according to the scheduler policy and the default preferences of the scheduler tag.
    • When there is a scheduler policy that matches the scheduler policy, the corresponding storage will be selected according to the scheduler tag and scheduler tag preference set in the scheduler policy. The scheduler tag preferences in the scheduler policy will override the default policy in the scheduler tag.
    • When there is no conforming scheduler policy, the optimal storage will be selected based on the default policy of the scheduler tag bound in the storage device.
  • When scheduler tag and scheduler tag preference are set, the set scheduler tag preference will override the default policy on the scheduler tag. The storage that provides the system disk is selected based on the scheduling preference as well as the scheduler tag.
    • Prefer: Scheduling prefers storage with this tag.
    • Avoid: Scheduling avoids storage with this tag.
    • Exclude: Exclude storage with this tag from scheduling.
    • Require: stores with this tag must be used when scheduling.
  • E.g. Take local storage as an example, local storage A is bound to scheduler tag A. The default policy for scheduler tag A is to use as much as possible. Local storage B is bound to scheduler tag B. The default policy for scheduler tag B is to prohibit its use. Scheduler Policy A is when creating a server in project A, select scheduler tag B, and scheduler policy preference is must use.
    • When the scheduler tag is not set, there are two cases as follows.
      • If the server belongs to project A, the system will prefer local storage B to provide storage for the server system disk.
      • When the server does not belong to project A, the system will prefer local storage A to provide storage for the server system disk.
    • When the scheduler tag is set to A and the policy is forbidden, the system will exclude local storage A and select local storage B to provide storage for the Server system disk.
  • Selete Block Storage: Users support selecting block storage for disks under the System View, and support to view the usage of storage, etc. which is currently only supported by VMware platform.
• Data disk: optional, you can add multiple data disks according to your needs, set the type, media, and capacity size of the disk. The optional type of disk is the same as the system disk. Only the first data disk supports selecting the disk type, the subsequent added data disks are of the same type as the first data disk.

  Note

  • Only the data disk of OneCloud platform supports viewing the media corresponding to the disk.
  • When creating an OpenStack server when the system disk is stored as an image, the data disk type can be set.
  • The data disk type for the VMware platform is the same as the system disk type.
  • The added data disk is only mounted to the server and will not automatically perform partitioning operations, but will need to be manually partitioned by the user after remotely connecting to the server.
  • Only OneCloud platform supports support for setting mount points, snapshotting build disks, and setting scheduler tags. Private clouds that use local storage also support the set scheduler tag feature.
    • Set scheduler tag: same as system disk.
    • Set mount point: Set the file type (ext4, xfs, swap) of the data disk, and the non-system directory where the data disk is mounted. Only one of them can be set: set mount point and snapshot build disk.
    • Snapshot build disk: Create data disk based on snapshot. You can view the existing snapshots in the On-premise. Only one of the two can be set: set mount point and snapshot build disk.
• Username: Show the administrator account of the server.
• Password: Set the administrator password, which is the password of root user in Linux system and administrator user in Windows OS.
  • Random Password: randomly generated administrator password, users can view the copied administrator password in the password column of the server list
  • Key Pair: You need to create a new key before associating the key. After associating the key, the user needs to use the private key to log in the server remotely.
  • Keep image settings: The administrator password is the existing administrator password in the image.
  • Custom Password: You can set the administrator password manually.

    Description

    • When you choose to boot from ISO, setting the administrator password is not support. The administrator password needs to be set when the user installs the OS.
    • Depending on the platform where the server is located, the administrator password may be set in one of the above ways, please see the interface.
• Networks: Set the IP address of the server.

  Note

  • VMware servers do not support VPC networks, only default classic networks can be selected.
  • Only OneCloud servers can select default classic and VPC networks.
  • Only OneCloud platform Servers support adding up to 8 networks, other platforms only support one network.
  • Auto scheduling: When Auto scheduling is selected, IP addresses are assigned to servers from the IP subnets where Auto scheduling is enabled.
  • Specify IP subnet: Select VPC and IP subnet. If you want to specify static IP, click “Manually configure IP” button to set IP address and click “OK” button.
  • Specify scheduler tag: Set the scheduler tag and the scheduler tag preference. The set scheduler tag preference will override the default policy on the scheduler tag. Select the optimal IP subnet based on the scheduler tag and scheduling preferences.
    • Prefer: Scheduling preference is given to IP subnets that have this tag.
    • Avoid: Try to avoid IP subnets with this tag when scheduling.
    • Exclude: Exclude IP subnets with this tag from scheduling.
    • Require: IP subnets with this tag must be used in scheduling.
  • E.g. if IP subnet A is bound to scheduler tag A, the default policy is prohibit, and IP subnet B is bound to scheduler tag B, the default policy is try to use. Scheduler Policy A is when the server belongs to project A. Select scheduler tag A and scheduler tag preference is must use.
    • When the network is selected as default when the server is created, there are two cases as follows.
      • When the server belongs to project A, the system will select IP subnet A to assign an IP address to the server.
      • When the server does not belong to project A, the system will select IP subnet B to assign an IP address to the server.
    • When the network selection specifies IP subnet A when creating a server, the system will select IP subnet A to assign an IP address to the server.
    • When the network selects scheduler tag A when creating a server and the tag preference is must use, the system will assign an unused IP address from IP subnet A to the server.
• Tag: Supports binding tags for newly created servers. Selecting existing tags and new tags is supported.
  • Create tag: Click the Create button at the top of the list, set the tag key and tag value, and click the “Add” button to create a new tag and bind it to the resource.
  • Select existing tags: Click “Existing Tags” button to select tag keys and values.

Advanced Configuration: Hidden by default, can be configured according to requirements.

• EIP: EIP is a kind of NAT IP that enables communication between servers and public network by binding with servers. The default is no binding, when you select “Create”, you need to configure the following parameters.
  • Line type: You can create the EIP of the corresponding line type according to your requirements.
  • Network billing method: Set the billing method of the EIP, including billing by traffic and billing by bandwidth.
    • Billed by flow: charge by actual transmission flow, which can limit the peak bandwidth to avoid the cost of unexpected traffic, and will drop packets when the instantaneous bandwidth exceeds the value, which is applicable to the occasion of large network fluctuation.
    • Billed by Bandwidth: Billed by transmission rate, choose fixed bandwidth, packets will be dropped when the bandwidth exceeds the value, suitable for scenarios with less network fluctuation.
  • Bandwidth: Set the bandwidth size.
• Public IP (Tencent Cloud and Alibaba Cloud): Public IP enables communication between servers and the public network by binding with servers. It includes EIP and Static Public IP. EIP can be flexibly bound or unbound with servers. Static public IP does not support unbinding with servers. The default is no binding. When you select “Create EIP” or “Create Static Public IP”, you need to configure the following parameters.
  • Network billing method: Set the billing method of the EIP, including billing by traffic and billing by bandwidth.
    • Billed by traffic: Billed by actual transmission traffic, which can limit the peak bandwidth to avoid the cost of unexpected traffic, and will drop packets when the instant bandwidth exceeds the value, which is suitable for the occasion of network fluctuation.
    • Billed by Bandwidth: Billed by transmission rate, choose fixed bandwidth, packets will be dropped when the bandwidth exceeds the value, suitable for scenarios with less network fluctuation.
  • Bandwidth: Set the bandwidth size.

    Note

    • On-premise platforms support binding elastic public IPs when creating servers for VPC networks, and only support per-bandwidth billing.
    • Public cloud platforms other than Tencent Cloud and AliCloud only support new EIP when creating new servers, Tencent Cloud and AliCloud platforms support new EIP and Static Public IP when creating new servers.
    • When creating an AWS server, if the selected VPC does not allow external network access, the new EIP is not allowed.
    • AWS, Azure, Google only support billed by traffic.
• Security Group: Set up security group rules for servers. Security group is a virtual packet filtering firewall that controls whether associated servers can be accessed and the external resources that servers can access by setting up security group rules, etc. A server supports binding up to 5 security groups.
• Scheduler Policy: The scheduler policy allows you to select the host or cloud account to which the server belongs.
  • Default: The system will select the optimal host for the server based on the scheduler policy and the scheduler tag.
    • Priority check the scheduler policy in the system, if there is a matching scheduler policy, the best host will be selected based on the scheduler tag and scheduler tag preference in the scheduler policy. The scheduler tag preferences in the scheduler policy will override the default policy in the scheduler tag.
    • When there is no matching scheduler policy, the system will select the optimal host based on the default policy of the scheduler tag bound to the host.
  • Host: The server will be created on the specified host.
  • Scheduler tag: Set the scheduler tag and the scheduler tag preference. The set scheduler tag preference will override the default policy of the scheduler tag. Select the corresponding host according to the scheduler tag and scheduler tag preference.
    • Use (prefer): Scheduling preference is given to hosts with this tag.
    • Avoid: Avoid hosts with this tag when scheduling.
    • Exclude: Exclude hosts with this tag from scheduling.
    • Require: Hosts with this tag must be used when scheduling.
  • E.g. If host A binds to scheduler tag A, the policy for scheduler tag A is disable. Host B is bound to scheduler tag B. The policy for scheduler tag B is try to use. Scheduler Policy A is when a server is created in project A, scheduler tag A is selected and scheduler policy preference is must use.
    • When the scheduler policy is selected as default when a server is created, there are two cases as follows.
      • When the server belongs to project A, the system will choose to create the server on host A.
      • When the server does not belong to project A, the system will choose to create the server on host B.
    • When scheduler tag A is selected and the scheduler tag preference is set to must use, the system will select to create the server on host A.
  • Cloud Subscription: The specified cloud subscription will be used to create servers on the private cloud platform, or VMware platform. If IP subnet is specified when configuring the network, only the cloud subscription where the IP subnet is located can be selected.
• Boot Firmware: Includes BIOS and UEFI modes, supported only by OneCloud platforms, and only UEFI mode is supported by the ARM architecture.
• High Availability: Only supported by OneCloud platform and requires no less than 2 hosts for the domain where the Servers are located or shared to the domain where the Servers are located to achieve high availability by creating a backup machine for the Servers, synchronizing data between the Servers and the backup machine on a regular basis, and when the Servers fail, the business will switch to the backup machine for normal use. It can quickly recover the business and reduce the business downtime caused by the failure of Servers. When enabling the high availability feature, you need to specify the host of the backup machine.
• Anti-affinity group: Select whether to check the unaffinity group. If checked, the unaffinity group needs to be selected, and the newly created Servers need to select the hosts, etc. according to the scheduling rules within the unaffinity group. If the scheduling rules are not satisfied, the creation may fail, which is only supported by OneCloud platform.

After the setup is complete, users can click the Create button to create a server.

If tickets are enabled, you need to fill in the reason for the application and click the “Submit Ticket” button to submit a ticket to create a server, and wait for approval before starting to create a server.

Example of host name expression

The host (including server and baremetal) name supports expressions in the format of ${variable name}, and the variable name needs to be lowercase. E.g. ${host}, the server name is displayed as the name of the host where the server is created; ${region}-${zone}, the name of the region - zone name, etc.
