These regions are generally supported. However, there are some Availability Zones within these regions that do not have the required c5n.9xlarge and c5n.18xlarge instances for Cloud Block Store. These Availability Zones are different for every customer. Customers can contact AWS Support to find out which Availability Zone does not include support for c5n.9xlarge and c5n.18xlarge instances, and avoid deploying Cloud Block Store in subnets tied to these Availability Zones.

** Cloud Block Store in an ActiveCluster configuration is not supported in Oregon if using with Pure1 Mediator. Customers who want to deploy Cloud Block Store with ActiveCluster in Oregon must use the On-Premises Mediator.

*** These regions are not supported because the Region or all the Availability Zone within these regions do not include support for one or more instances or service that Cloud Block Store utilizes, Check the appendix below for more details.

Cloud Block Store on AWS and on Azure is utilizing a range of services and instances. Generally, not all instances types can be available in all the regions, This might be due to the limited number of instances or it might be available upon customer request. As CBS platform is built on the certain instance that has been designed, tested, and selected carefully to provide the capabilities and performance that can be leveraged. 

We aim to keep the tables above up to date, however, it is recommended to check the instances availability in the selected region before deploying. 

Check AWS Resources 

Instance Type 

In a Terminal, Install and configure AWS CLI, then execute the command: 

For v20 Model: c5n.18xlarge

For v10 Model: c5n.9xlarge

aws ec2 describe-instance-type-offerings \
--filters Name=instance-type,Values=<instance_type> \
--query "InstanceTypeOfferings[].InstanceType" \
--region <region-name>

Alternatively, use AWS CloudShell, see the example below: 


Check Azure Resources

Instance Type and Ultra Disks 

In Azure Console, open Cloud Shell, choose Powershell, and execute the below: 

For v20 Model: D64s_v3

For v10 Model: D32s_v3

$region = "southeastasia"
$vmSize = "Standard_D32s_v3"
$sku = (Get-AzComputeResourceSku | where {$_.Locations.Contains($region) -and ($_.Name -eq $vmSize) -and $_.LocationInfo[0].ZoneDetails.Count -gt 0})
if($sku){$sku[0].LocationInfo[0].ZoneDetails} Else {Write-host "$vmSize is not supported with Ultra Disk in $region region"}
