Mission critical performance with Ultra SSD for SQL Server on Azure VM

This blog post was authored by Mine Tokus, Senior Program Manager, COGS Data – SQL DB.

We recently published “Storage Configuration Guidelines for SQL Server on Azure VM” on the SQL Database Engine Blog summarizing the test findings from running TPC-E profile test workloads on premium storage configuration options. We continued this testing by including Ultra SSD. Ultra SSD is the new storage offering available on Microsoft Azure for mission-critical workloads with sub-millisecond latencies at high throughput. We will summarize the test details and findings in this blog.

We used DS14_v2 VM with 16 cores, 112GB memory and 224GB local SSD for this test. This virtual machine (VM) is capable of scaling up to 51,200 uncached IOPS and 64,000 cached and temporary IOPS. We selected a TPC-E workload representative OLTP app in e-commerce/trade space as the test workload. Our test workload drives a similar percentage of read and write IO activity.

Size vCPU Memory: GiB Temp storage (SSD) GiB Max cached and temp storage throughput: IOPS/MBps (cache size in GiB) Max uncached disk throughput: IOPS/MBps Standard_DS14_v2 16 112 224 64,000/512 (576) 51,200/768 Premium Storage Configuration

For Premium Storage Configuration, we added 10 -P30 disks and enabled RO cache for all

Avere vFXT for Azure for HPC workloads now generally available

We are very excited to share the general availability (GA) of Avere vFXT for Azure. This culminates months of effort beginning when Microsoft welcomed Avere to the Azure family earlier this year. Customers can now leverage the Avere vFXT to run their high-performance applications in Azure.

The scope of Microsoft Azure’s solutions for high-performance computing (HPC) continues to broaden with Avere vFXT being the latest product to transition from testing to general availability. Avere joins a stellar portfolio of products like Azure Virtual Machines, Azure Batch, Azure CycleCloud, and networking technologies such as Azure ExpressRoute, that helps bring these demanding projects into the cloud without sacrifices.

Since public preview began in late August 2018, customers across the globe have moved new workloads to Azure using our high-performance file caching technology. The Avere vFXT has been deployed at scale, providing data access at very low latency, no matter where the file data originated. The Avere vFXT is deployed as a set of Azure Virtual Machines, adjacent to your cloud-based HPC cluster. The software runs as a cluster of VMs, enabling very high scale and throughput capacity for compute clusters of any size. Sources of storage can also connect into the Avere

Azure Update Management: A year of great updates
Azure Update Management: A year of great updates

Azure Update Management is a service included as part of your Azure Subscription that enables you to assess your update status across your environment and manage your Windows and Linux server patching from a single pane of glass, both for on-premises and Azure.

Update Management is available at no additional cost (you only pay for log data stored in the Azure Log Analytics service) and can easily be enabled on Azure and on-premises VMs. To try it, simply navigate to your VM tab in Azure and enable Update management on one or more of your machines.

Over the past year we’ve been listening to your feedback and bringing powerful new capabilities to Azure Update Management. Here’s a look at some of the new features we have developed with your help.

Groups

One of the biggest asks from the community this year is for more flexibility in targeting update deployments, specifically support for groups with dynamic membership. Instead of specifying a static set of machines when you create an update deployment, groups allow you to specify a query that will be evaluated each time an update deployment occurs.

We have released a preview feature that enables you to create an Azure-native

Approve, audit support access requests to VMs using Customer Lockbox for Azure

As a cloud service provider, we understand the importance of maintaining the integrity and confidentiality of customer data. To continue to help you maximize your data security and privacy, we are announcing Customer Lockbox for Microsoft Azure. It is a service integrated into Azure portal that gives you explicit control in the very rare instance when a Microsoft Support Engineer may need access to your data to resolve an issue.

There are very few instances, such as a debugging remote access issue, where a Microsoft Support Engineer requires elevated permissions to resolve this issue. In such cases, Microsoft engineers use just-in-time access service that provides limited, time-bound authorization with access limited to the service. While Microsoft has always obtained customer consent for access, Customer Lockbox now gives customers the ability to review and approve or deny such requests from Azure Portal. Until the request is approved, Microsoft Support Engineer will not be granted access.

The entire process is audited so customers maintain full visibility and control. All Customer Lockbox activity will be available in Azure Portal. If you are using Azure Security Center, the VM agent that you have installed on your virtual machines can provide logs on activities

Reservations now available for US Government cloud regions

Reservations are now generally available for US government Azure customers. Reservations are available for virtual machines, SQL Server and Cosmos DB for US Government and US DoD Azure regions.

Reservations can help you save money on workloads that have consistent usage, providing price predictability to support your budgeting and forecasting needs. Also, reservations provide unprecedented flexibility should your business need change. We’ve made it easy to exchange your reservations and make changes including the ability to modify your region, sizes or term. Unlike other cloud providers, you can cancel reservations at any time and get a refund. Reservations are available in the following Azure Government regions: US Gov Arizona, US Gov Texas, US Gov Virginia, US DoD Central, and US DoD East.

Azure is the cost-effective cloud for Windows Server workloads

If you are a Windows Server customer with Software Assurance or a Windows Server Subscription, you can combine reservations with the Azure Hybrid Benefit for significant savings. In particular, if you are running Windows Server 2008, Azure offers the most cost-effective approach to running in the cloud.

With Azure Reserved VM Instances and Azure Hybrid Benefit, Azure is the most cost-effective public cloud to run your Windows Server

Ephemeral OS Disk in limited preview
Ephemeral OS Disk in limited preview

Last week at Microsoft Ignite, we launched Ultra SSD, a new industry leading high-performance disk type for IO intensive workloads. Adding to that, today we are delighted to share the limited preview of Ephemeral OS Disk, a new type of OS disk created directly on the host node, providing local disk performance and faster boot/reset time.

Ephemeral OS Disk is supported for all virtual machines (VM) and virtual machine scale sets (VMSS). This offering is based on your feedback to provide a lower cost, higher performant OS disk for stateless applications, which enable them to quickly deploy the VMs and reset them to its original state.

Ephemeral OS Disk is ideal for stateless workloads that require consistent read/write latency to OS disk, as well as frequent reimage operations to reset the VM(s) to the original state. This includes workloads such as website applications, game server hosting services, VM pools, computation, jobs and more. Ephemeral OS Disk also works well for workloads that are leveraging low-priority VM scale sets.

Announcing private preview of Azure VM Image Builder

Today I am excited to announce the private preview of Azure VM Image Builder, a service which allows users to have an image building pipeline in Azure. Creating standardized virtual machine (VM) images allow organizations to migrate to the cloud and ensure consistency in the deployments. Users commonly want VMs to include predefined security and configuration settings as well as application software they own. However, setting up your own image build pipeline would require infrastructure and setup. With Azure VM Image Builder, you can take an ISO or Azure Marketplace image and start creating your own golden images in a few steps.

How it works

Azure VM Image Builder lets you start with either a Linux-based Azure Marketplace VM or Red Hat Enterprise Linux (RHEL) ISO and begin to add your own customizations. Your customizations can be added in the form of a shell script, and because the VM Image Builder is built on HashiCorp Packer, you can also import your existing Packer shell provisioner scripts. As the last step, you specify where you would like your images hosted, either in the Azure Shared Image Gallery or as an Azure Managed Image. See below for a quick video on how

Rich insights for virtual machines from Azure Monitor
Rich insights for virtual machines from Azure Monitor

At Ignite we announced the public preview of Azure Monitor for VMs, a new capability that provides an in-depth view of VM health, performance trends, and dependencies. You can access Azure Monitor for VMs from the Azure VM resource blade to view details about a single VM, from Azure Monitor to understand compute issues at scale, and from the Resource Group blade to understand whether all the VMs in a common deployment are behaving as you expect.

Azure Monitor for VMs brings together key monitoring data about your Windows and Linux VMs, allowing you to:

Monitor the health and availability of VMs, with customizable alert thresholds Troubleshoot guest-level performance issues and understand trends in VM resource utilization Determine whether back-end VM dependencies are connected properly, and which clients of a VM may be affected by any issues the VM is having Discover VM hotspots at scale based on resource utilization, connection metrics, health signals and alerts Health

Health capabilities in Azure Monitor for VMs include out of the box configurable VM Health criteria that are powered by the same health modeling services used internally across Microsoft.

Health gives you powerful views to VM availability signals, including how many VMs are
