English original:Microsoft Releases Managed Disks, Scale Sets

Microsoft Corey Sanders in ablog postCareful planning.

You have to make sure that you don't have too many disks in the same storage account because it will go beyond the extended target of the storage account (for example, 20000 IOPS). In order to get the best performance of a virtual machine, you must know how to maximize the use of the stored account when using an unmanaged disk.

Taking into account the IOPS limit, the userMust be accurately calculatedNumber of virtual machines that can be used in each storage account.

Depending on the requested rate limit, you can roughly estimate the number of highly available disks supported by a standard storage account. For example, for the basic level (Basic Tier) virtual machine, the maximum number of high available disk is about 66 (20000 divided by each disk IOPS 300); for the standard level (Standard Tier) virtual machine, the number is about 40 (20000 divided by each disk IOPS 500).

Microsoft recommendationAll new virtual machines use managed disks, and it is recommended that all existing virtual machines migrate to this mode.According to Sanders introductionIt is easy to migrate to a managed disk or to migrate between standard and advanced disk services.

Using the managed disks from the existing non controlled Azure Resource Manager virtual machine to managed virtual machine disk transplantation is very easy to implement, it needs no reconstruction of the virtual machine, and retains the configuration and security of virtual machine. After starting the migration, the virtual machine can be used immediately after reboot. You can completely control the migration process, and you can choose to migrate a virtual machine every time, or through the script to migrate all virtual machines.

Now you can easily transfer managed disks from standard disks to advanced disks. With a managed disk, you can change the account type of the disk by turning off the virtual machine, without removing or reconfiguring the virtual machine. After the virtual machine restarts, the changed disk is available immediately.

Extended collection of Azure virtual machinesAllows users to build and manage a set of the same virtual machine resources.According to Microsoft, the user must build a collection of more than 100 virtual machines using managed disks. If you do not use a managed disk, each 20 virtual machine will use a traditional storage account.After using managed disksThere are 1000 virtual machines that can be included in the extended collection, but this is only based on the underlying image provided by Azure. If you use a custom - based mirror, the extended collection can contain up to 100 virtual machines.

In order to make the expansion set as fast as possible,Microsoft uses a reservation allocation (over-provisioning) strategy.

Sanderspoint outMicrosoft IaaS platform also plans a number of other features.

I am looking forward to this year to release more features, including support for operating system patches, application lifecycle integration, application health monitoring and integration of the health of the load balancer.
