Windows Azure 发布 SSD 虚拟机

刚刚收到微软发来的邮件，说基于SSD硬盘的虚拟机以及上线，叫做D系列，区别于之前虚拟机的A系列。具体内容如下：
We’ve announced the general availability of a new series of Standard tier instances called the D-series for Virtual Machines and Cloud Services and its related pricing.

These instances have solid-state disk (SSD)-based local drives and faster processors relative to many of the A-series instances. The D-series instances can be used as VMs, as well as web or worker roles in Cloud Services, and are well suited for applications that demand faster CPU performance, local disk performance, or higher memories. Please note that the SSD drives in the D-series are non-persistent.

Following are the CPU, memory, and disk configurations of the D-series instances:

Name Number of vCPUs Memory (GB) SSD Local Disk (GB)
General Purpose
STANDARD_D1 1 3.5 50
STANDARD_D2 2 7 100
STANDARD_D3 4 14 200
STANDARD_D4 8 28 400
Memory Intensive
STANDARD_D11 2 14 100
STANDARD_D12 4 28 200
STANDARD_D13 8 56 400
STANDARD_D14 16 112 800

Through December 31, 2014, the prices for Standard D-Series Virtual Machines will be charged at US South Central rates for all regions. We are currently offering promotional pricing and any future price increases will be announced with 30 days' notice.

For more information, visit the Virtual Machines webpage. To get a comprehensive look at pricing, visit the Virtual Machines Pricing Details webpage.

Note: As an Azure customer, you are receiving this email because we are required to notify you of all pricing changes. This is the only communication that you will receive directly from Microsoft regarding these pricing changes.

Thank you,

Your Azure Team

至于价钱，由于Azure的价钱页面没有更新，所以我登陆自己的订阅账号查看了一下，如下：
D1 63.24
D2 126.48
D3 252.96
D4 505.92

D11 159.22
D12 318.43
D13 572.88
D14 1031.93
单位都是美元/月
D系列目前只有STANDARD没有BASIC。

本来想测试一下读写的，但是没想到性能太渣。。。还没测完。。。只好一会测完了再补。。。
