Features and Benefits
Extreme availability and scale
DM Series is engineered to meet demanding availability requirements. Highly reliable Lenovo hardware, innovative software, and sophisticated service analytics deliver 99.9999% availability or greater through a multilayered approach.
Scaling up is also easy. Simply add more storage, flash acceleration, and upgrade the controllers. To scale out, grow from a base of two nodes to a 12-array cluster containing up to 44PB (SAN) or 88PB (NAS) of capacity. You can cluster with DM Series all-flash models for flexible growth as your business demands.
Optimize your data
For an enterprise-class hybrid cloud that offers predictable performance and availability, combine your DM Series storage array with Cloud Volumes ONTAP. This seamlessly integrates with and replicates data to multiple clouds, such as IBM Cloud, Amazon Web Services (AWS), or Microsoft Azure.
FabricPool allows you to tier cold data to the cloud to free up space on expensive and high performing flash media. When using FabricPool you can tier data to Amazon Web Services, Microsoft Azure, Google Cloud, IBM Cloud and Alibaba cloud.
