Azure cloud storage offers 64 TB on a single VM

Microsoft Azure cloud builds on G-series virtual machines with the launch of GS-series, which can scale up to 64 TB of storage on a single VM.

Microsoft this week bulked up the size of virtual machines in its Azure cloud storage with the launch of 64 TB GS-series virtual machines (VMs).

The GS-series builds on the Azure cloud G-series that Microsoft launched in January. Besides offering 64 TB of storage, each GS VM provides 80,000 IOPS and 2,000 MBps of throughput to the back-end storage.

The GS-series enables databases, data warehouses and other large-scale applications to work in the Microsoft Azure cloud. Azure also announced price cuts for its existing D-series and DS-series VMs, which support solid-state drives (SSDs). The price of those VMs will be cut up to 27%.

"Each GS-series VM is allocated a fixed-amount of SSD, managed by a component called Blobcache, to provide a low-latency, high-throughput cache for the persistent disks using Premium Storage," Daniel Wu, senior program manager for Microsoft's Azure group, wrote on a blog announcing the GS-series. "Each GS-series VM is allocated a smaller amount of local SSD storage compared to its G-series counterpart."

GS-series VMs offer up to 32 vCPUs, 448 GB of memory and 6.59 TB of local SSDs. As the rest of the G-series, the GS-series runs on the Intel Xeon E5 v3 processors.

"The GS-series combines the power of G-series with the performance of Azure Premium Storage," Wu wrote.

Microsoft Azure cloud storage offers two types of durable storage: Its Premium Storage stores data on SSDs and the Standard Storage stores data on hard disk drives. The GS-series continues Microsoft's quest to improve Azure in the face of stiff competition from Amazon Web Services (AWS) and Google Cloud Platform.

Earlier this summer, Microsoft Azure announced general availability of new functionality in its Azure Site Recovery for heterogeneous workload support for recovery, cloud migration and management capabilities in multiple environments, including AWS and VMware.

The functionality is built on technology from Microsoft's InMage acquisition. It provides the ability to do migration from AWS to Azure, and provides support for recovery in Azure for VMware and physical servers. It allows customers to use a secondary site, private cloud or Azure as a disaster recovery site.
