Integrated Virtualization Foundation (HCI)

basic information

The university-wide information infrastructure system ITC2022 is a university-wide integrated virtualization infrastructure (HCI) jointly implemented by several departments within the university. Some resources of the university-wide integrated virtualization infrastructure are available for general use within the university. The user is required to pay a portion of the equipment lease and maintenance fees.

usage rule

Please be aware of the following information in advance when using it.

• About Service

  • The service is scheduled to be available until around January 2026.

    • Succession services are under consideration.

  • Depending on hardware resource usage, you may not be able to provide services or change virtual machine configuration

  • We have about weekly backups for emergencies, but we cannot guarantee the recovery of the latest data.

• About Virtual Machine Management

  • Information Infrastructure Center management responsibilities are limited to Virtualization Infrastructure (HCI).

  • Virtual machine administrator is a member of our university with a valid UEC account.

  • User must deploy OS/application to virtual machines on HCI

    • The Information Infrastructure Center does not support the introduction, configuration, or use of the OS or application. Please use the software manufacturer’s documentation and community to take care of it yourself.

  • Be sure to install VM Tools on virtual machines

    • Installation varies by operating system. Please refer to the documentation for each operating system.

  • Operational maintenance including updates should be performed by the user

  • Please back up data

• About Availability

  • The HCI is configured to be redundant against hardware failures, but cannot completely prevent system failures caused by failures. Alternatives should be provided by the user if necessary.

  • In the event of an emergency, such as a failure or a security incident, the Information Infrastructure Center may shut down the virtual machine without the permission of the user.

  • Virtual machine operations may stop temporarily for a short period of time due to the processing required for HCI management/maintenance

  • Virtual machines do not stop even in the event of a full university power outage, but peripheral services and network outages may affect the services that virtual machines provide.

• Prohibited

  • Not available for commercial purposes only for academic purposes

    • Please be careful when using it for joint research with companies.

  • Do not overburden the hardware of the hardware.

    • Our HCI is not intended to be used for high performance calculations (HPCs). If ITC determines that other virtual machines will have a significant impact on them, they may stop them without your permission.

Allocate virtual machine resources (CPU, memory, storage)

Allocate resources based on per resource (RU). There are three types of resources: virtual CPU (vCPU), virtual memory (vMem), and virtual storage (vStrage).

The unit of resources is equivalent to one virtual CPU, 8GB virtual memory, and 512GB virtual storage.

Hint

Per Resource (RU) = 1 Virtual CPU (vCPU) = 8 GB Virtual Memory (vMem) =512 GB Virtual Storage (vStorage)

Virtual machine operation requires at least one vCPU, vMem, and vStorage per resource, totaling three resource units.

Hint

Minimum Virtual Machine Configuration: 3 Resource Units (RU)

CPU	1
memory	8 GB
storage	512 GB

Additional resource units (RUs) may be added as needed. For example, adding 8 GB of memory (= 1 RU) to the minimum configuration of 3 RU virtual machine will give you a 4 RU virtual machine (1 vCPU, 16 GB vMem, 512 GB vStorage).

Pay yourself

Per Resource (RU)

twenty thousand yen per year

Minimum Virtual Machine Configuration (1vCPU, 8GB Mem, 512GB Storage)

60,000 yen per year (3 RU)

Resource Unit, please refer to Allocate virtual machine resources (CPU, memory, storage).

Usage and flow of usage

Start using a virtual machine

1. ITC Fee Group Registration and Application for Virtual Machine Resource Units

   For new registrations and virtual machine resource unit changes, please apply using the same form. For more information, please refer to Use registration/change (ITC paid service group registration/change).

2. Virtual Machine Creation Request

   See Create Virtual Machine and Change Resource Allocation Request.

3. OS Installation

   See Installing OS on Virtual Machines.

Install the OS on a Virtual Machine

1. Log in to Virtualization Foundation (HCI)

   Log in from https://hci.cc.uec.ac.jp/ui/ with the following ID/password

   ID

   Virtual Machine Administrator UEC Account @hci.cc.uec.ac.jp

   password

   Password for the UEC account

   Hint

   The ID is not only a UEC account, but also a UEC account with @hci.cc.uec.ac.jp.

2. Mount the ISO image for installation on a virtual machine

   Click hci.cc.uec.ac.jp \(\Rightarrow\) hci-datacenter \(\Rightarrow\) ITC paid group number \(\Rightarrow\) virtual machine name, and click Edit Settings… button

   

   \(\Downarrow\)

   Click on CD/DVD drive to expand the menu. Select Datastore ISO file from the pull-down menu, check Connect at power-on under Status, and click Browse….

   

   \(\Downarrow\)

   Select an ISO image of the OS to be installed from image-container \(\Rightarrow\) ISO and click OK.

   

   \(\Downarrow\)

   Finally, click OK on the Edit Settings screen to close the window.

3. Boot the virtual machine and install the OS

   Click to specify the virtual machine you want to boot and press the Power On button.

   Once the mounted ISO image is correctly recognized by the virtual machine, the OS installer will start from the mounted ISO image after the virtual machine is powered on.Install the OS according to the OS manual.

   

   Hint

   If you are using Windows Server on the HCI, you can use the Windows Server Datacenter license contracted by the university. After installation, you will need to enter your product key for activation, so please contact support@cc.uec.ac.jp .

4. Install VMware Tools

   Refer to the documentation for each operating system and install Open VM Tools.

Stop/Reboot a Virtual Machine

1. Log in to Virtualization Foundation (HCI)

   Log in from https://hci.cc.uec.ac.jp/ui/ with the following ID/password

   ID

   Virtual Machine Administrator UEC Account @hci.cc.uec.ac.jp

   password

   Password for the UEC account

   Hint

   The ID is not only a UEC account, but also a UEC account with @hci.cc.uec.ac.jp.

2. Perform start/stop/restart from power action

   Select the virtual machine you want to perform and perform the desired operation from the right-click menu.

• Registration with DNS is not required for virtual machine name (hostname, FQDN, etc.)

• The group number is notified to the group administrator in the registration completion notice at the time of ITC fee-based service registration.

• Please refer to Allocate virtual machine resources (CPU,memory,storage) for information on how to specify resource units to be allocated to virtual machines.

• Please note that if the resource unit allocated to the virtual machine exceeds the number of registered units, the registration operation will not be possible.

• If you are creating more than one drive in the virtual machine, please specify the number of drives you need, e.g. (drive 2) Number of resource units allocated for storage:.

• If you change the capacity of a specific drive in an existing virtual machine, it is recommended that you do not change it unless it is unavoidable. Please note that even if the change fails, the information center will not be able to recover.

• For the IP address to be assigned, please specify the IP address that has been allocated by the subnet administrator beforehand.
