Viewing a Service Offering (by filter)

Perform the following steps to view a service offering:

1. On the left panel, click Service Offerings.
   The Service Offerings page displays.

2. Click the Select view drop-down list and select an option to view the service offering. The following options are provided:

   
   

   Field Name	Description
   Compute Offerings	Defines the specifications of a virtual machine created from the compute offering. Important features include defining the amount of RAM and CPU cores. You can add a compute offering from this page. Note: Leaseweb provides some pre-defined compute offerings out-of-the-box.
   Disk Offerings	Defines the specifications of a disk from which you can create a data volume. You can add disk offering from this page. Note: Leaseweb provides some pre-defined disk offerings out-of-the-box.

3. Based on your selection, the following information is displayed:

   Compute Offering:

   Field Name	Description
   Name	Displays the name of the compute offering. Note: You can click on individual compute offerings to view additional information and perform various tasks.
   Description	Displays a brief description of the compute offering (that was entered during the time of creation).
   Order	Use the following icons to arrange the displays of compute offerings: Click this to move the compute offering to the top of the list. Click this to move the compute offering to the bottom of the list. Click this to move the compute offering a row above. Click this to move the compute offering a row below. Click this to drag and drop the compute offering to any position on the list.
   Quickview	Displays an overview of the compute offerings and the tasks that can be performed on them.

   Disk Offering:

   Field Name	Description
   Name	Displays the name of the disk offering. Note: You can click on individual disk offerings to view additional information and perform various tasks.
   Description	Displays a brief description of the disk offering (that was entered during the time of creation).
   Custom Disk Size	Displays whether the disk offering allows you to customize the size of the disk. If it displays Yes, then during instance creation using this disk offering, you will get a slider using which you can adjust the disk size.
   Disk Size	Displays the size of the disk for the disk offering.
   Order	Use the following icons to arrange the display of disk offerings: Click this to move the disk offering to the top of the list. Click this to move the disk offering to the bottom of the list. Click this to move the disk offering a row above. Click this to move the disk offering a row below. Click this to drag and drop the disk offering to any position on the list.
   Quickview	Displays an overview of the disk offerings and the tasks that can be performed on them.

Adding a Compute Offering

Perform the following steps to add a compute offering:

1. On the left panel, click Service Offerings.
   The Service Offerings page displays.
   
   
2. Click the Select view drop-down list and select Compute Offerings.
   The Compute Offerings page display
   
3. Click the +Add compute offering button.
   The Add compute offering dialog box displays.
   
   
   

4. Enter the following information and click OK. 

   
   

   Field Name	Description
   Name	Enter a name using which you can identify the compute offering.
   Description	Enter a description for the compute offering. This description will help you to identify the compute offering when you need to select one for creating an instance.
   Storage Type	"Shared" is the only option. This ensures that the volume resides on the shared storage that is external to the hypervisor. If the hypervisor your instance is running on dies, it will not affect the data on the storage.
   Provisioning Type	The "thin" provisioning  is the only option .Creating volume using  thin provisioning yields better storage capacity utilization efficiency.
   Compute offering type	Fixed Offering User has no ability to customise Custom Constrained User has some latitude to customise the compute within parameters set by the offering. Custom Unconstrained User can set any values that they wish
   CPU Cores	Enter the number of CPU cores you want to assign to the compute offering. Once this compute offering is attached to an instance, the instance will have the assigned number of CPU cores available for processing.
   Memory (in MB)	Enter the amount of RAM you want to assign to the compute offering (in MB).
   Disk Read Rate (BPS)	Allowed disk read rate in bytes per second.
   Disk Write Rate (BPS)	Allowed disk write rate in bytes per second.
   Disk Read Rate (IOPS)	Allowed disk read rate in IOPS (input/output operations per second).
   Disk Write Rate (IOPS)	Allowed disk write rate in IOPS (input/output operations per second).
   Network Rate (MB/s)	Enter the limit for the network speed (in Mbps) of the compute offering.
   QoS Type	Select a quality of service: Empty no quality of service hypervisor rate limiting enforced on the hypervisor side storage guaranteed minimum and maximum IOPS enforced on the storage Note: Currently, Leaseweb does not support this functionality. So choices made here will have no effect.
   Offer HA	Select this to enable high availability. Note: This ensures that if the hypervisor on which your instance is deployed dies, your instance will start on another hypervisor.
   CPU cap	Whether to limit the level of CPU usage even if spare capacity is available.
   Volatile	Select this check box to reset root disks of instances upon reboot. This is useful for secure environments that need a fresh start on every boot and for desktops that should not retain state. Note: On reboot, all data will be lost.
   GPU	Field to assign a physical GPU card to guest VM for graphics. Currently, Leaseweb does not support this functionality. So choices made here will have no effect.
   Domain	You can only select the name of your domain (resource pool).

Adding a Disk Offering

Perform the following steps to add a disk offering:

1. On the left panel, click Service Offerings.
   The Service Offerings page displays.
   
   
2. Click the Select view drop-down list and select Disk Offerings.
   The Disk Offerings page displays.
   
   
   
3. Click the +Add Disk Offering button.
   The Add Disk Offering dialog box displays.
   
   
   

4. Enter the following information and click OK. 

   
   

   Field Name	Description
   Name	Enter a name using which you can identify the disk offering.
   Description	Enter a description for the disk offering. This description will help you to identify the disk offering when you need to select one for creating an instance.
   Storage Type	Select the shared option. This ensures that the volume resides on the shared storage that is external to the hypervisor. If the hypervisor dies, it will not affect the data on the storage. Note: Do not select the local option. Currently, Leaseweb does not support this functionality. You can successfully create a disk offering by selecting the "local" option. However, you will not be able to create an instance by attaching this disk offering to it.
   Provisioning Type	The "thin" provisioning  is the only option .Creating volume using  thin provisioning yields better storage capacity utilization efficiency.
   Custom Disk Size	Select this check box to enable the slider (during configuring an instance) for setting the disk size. Note: If you select this, the Disk Size field will not display, else user can set own disk size
   Disk Size	Enter the size of the disk for the disk offering, up to 1TB in size. Note: Ensure that it is within the limit of resources in your resource pool
   QoS Type	Select a quality of service: Empty no quality of service hypervisor rate limiting enforced on the hypervisor side storage guaranteed minimum and maximum IOPS enforced on the storage Note: Currently, Leaseweb does not support this functionality. So choices made here will have no effect.
   Disk Read Rate (BPS)	Allowed disk read rate in bits per second.
   Disk Write Rate (BPS)	Allowed disk write rate in bits per second.
   Disk Read Rate (IOPS)	Allowed disk read rate in IOPS (input/output operations per second).
   Disk Write Rate (IOPS)	Allowed disk write rate in IOPS (input/output operations per second).
   Domain	Select the name of your domain (resource pool).
