Azure Premium SSD v2 Disk Storage in preview | Azure Weblog and Updates

We’re excited to announce the preview of Premium SSD v2, the following technology of Microsoft Azure Premium SSD Disk Storage. This new disk providing supplies probably the most superior block storage answer designed for a broad vary of enter/output (IO)-intensive enterprise manufacturing workloads that require sub-millisecond disk latencies in addition to excessive enter/output operations per second (IOPS) and throughput—at a low value. With Premium SSD v2, now you can provision as much as 64TiBs of storage capability, 80,000 IOPS, and 1,200 MBPS throughput on a single disk. With best-in-class IOPS and bandwidth, Premium SSD v2 supplies probably the most versatile and scalable general-purpose block storage within the cloud, enabling you to fulfill the ever-growing calls for of your manufacturing workloads resembling—SQL Server, Oracle, MariaDB, SAP, Cassandra, Mongo DB, massive information, analytics, gaming, on digital machines, or stateful containers. Furthermore, with Premium SSD v2, you may provision granular disk sizes, IOPS, and throughput independently based mostly in your workload wants, offering you extra flexibility in managing efficiency and prices.

With the launch of Premium SSD v2, our Azure Disk Storage portfolio now consists of some of the complete units of disk storage choices to fulfill workloads starting from Tier-1 IOPS intensive workloads resembling SAP HANA to basic function workloads resembling RDMS and NoSQL databases and cost-sensitive Dev/Check workloads.

Advantages of Premium SSD v2

As clients transition their manufacturing workloads to the cloud or deploy new cloud-native purposes, balancing efficiency and price is high of thoughts. For instance, transaction-intensive database workloads might require excessive IOPS on a small disk measurement or a gaming utility might have very excessive IOPS throughout peak hours. Equally, massive information purposes like Cloudera/Hadoop might require very excessive throughput at a low value. Therefore, clients want the flexibleness to scale their IOPS and throughput unbiased of the disk measurement. With Premium SSD v2, you may customise disk efficiency to exactly meet your workload necessities or seasonal calls for, with out the necessity to provision further storage capability.

Premium SSD v2 additionally lets you provision storage capability starting from 1 GiB as much as 64 TiB with GiB increments. All Premium SSD v2 disks present a baseline efficiency of three,000 IOPS and 125 MB/sec. In case your disk requires greater efficiency, you may provision the required IOPS and throughput at a low value, as much as the max limits proven under. You possibly can dynamically scale up or scale down the IOPS and throughput as wanted with out downtime, permitting you to handle disk efficiency cost-effectively whereas avoiding the upkeep overhead of striping a number of disks to realize extra efficiency. Summarizing the important thing advantages:

  • Granular disk measurement in 1 GiB increments.
  • Unbiased provisioning of IOPS, throughput, and GiB.
  • Constant sub-millisecond latency.
  • Simpler upkeep with scaling efficiency up and down with out downtime.

Premium SSD v2, like all different Azure Disk Storage choices, will present our industry-leading information sturdiness and excessive availability at basic availability.

Following is a abstract evaluating Premium SSD v2 with the present Premium SSD and Extremely Disk.

Supported Azure Digital Machines

Premium SSD v2 can be utilized with any premium storage-enabled digital machines sizes enabling you to leverage a various set of digital machine sizes. Presently, Premium SSD v2 can solely be used as information disks. Premium SSDs and Customary SSDs can be utilized as OS disks for digital machines utilizing Premium SSD v2 information disks.


Premium SSD v2 disks are billed hourly based mostly on the provisioned capability, IOPS, and MBPS. Let’s take an instance of a disk that you just provision with 100 GiB capability, 5000 IOPS, and 150 MB/sec throughput.

  • The disks are billed per GiB of the provisioned capability. Therefore, you may be charged for 100 GiB of the provisioned capability.
  • The disks are billed for any further IOPS provisioned over the free baseline of three,000 IOPS. On this case, because you provisioned 5000 IOPS, you may be billed for the extra 2,000 IOPS.
  • The disks are billed for any further throughput over the free baseline throughput of 125 MB/s. On this case, because you provisioned 150 MB/sec throughput, you may be billed for the extra 25 MB/s throughput.

You possibly can be taught extra on the Azure Managed Disks pricing web page.

Getting Began

Premium SSD v2 is at the moment obtainable in preview in choose areas. If you’re all for taking part within the preview, you may request entry to get began. As soon as enrolled within the preview program, it is possible for you to to create and handle Premium SSD v2 by way of the Azure portal, PowerShell, and CLI SDKs. You possibly can seek advice from the Premium SSD v2 documentation to be taught extra.
