 ## Ultra disks
 
-Azure ultra disks are the highest-performing storage option for Azure virtual machines (VMs). You can change the performance parameters of an ultra disk without having to restart your VMs. Ultra disks are suited for data-intensive workloads such as SAP HANA, top-tier databases, and transaction-heavy workloads.

You can change the performance parameters of an Ultra Disk without having to restart your VMs. Ultra Disks are suited for data-intensive workloads such as SAP HANA, top-tier databases, and transaction-heavy workloads.
 
 Ultra disks must be used as data disks and can only be created as empty disks. You should use Premium solid-state drives (SSDs) as operating system (OS) disks.
 
 ### Ultra disk size
 
-Azure ultra disks offer up to 100 TiB per region per subscription by default, but ultra disks support higher capacity by request. To request an increase in capacity, request a quota increase or contact Azure Support.

-Ultra disks are designed to provide low sub millisecond latencies and provisioned IOPS and throughput 99.99% of the time. Ultra disks also feature a flexible performance configuration model that allows you to independently configure IOPS and throughput, before and after you provision the disk. You can adjust the performance of an Ultra Disk four times within a 24 hour period. Ultra disks come in several fixed sizes, ranging from 4 GiB up to 64 TiB.

-Ultra disks support IOPS limits of 300 IOPS/GiB, up to a maximum of 400,000 IOPS per disk. To achieve the target IOPS for the disk, ensure that the selected disk IOPS are less than the VM IOPS limit. Ultra disks with greater IOPS can be used as shared disks to support multiple VMs.

-The minimum guaranteed IOPS per disk are 1 IOPS/GiB, with an overall baseline minimum of 100 IOPS. For example, if you provisioned a 4-GiB ultra disk, the minimum IOPS for that disk is 100, instead of four.

-You can adjust ultra disk IOPS and throughput performance at runtime without detaching the disk from the virtual machine. After a performance resize operation has been issued on a disk, it can take up to an hour for the change to take effect. Up to four performance resize operations are permitted during a 24-hour window.

 It's possible for a performance resize operation to fail because of a lack of performance bandwidth capacity.
