Dell EMC uses cloud to offer cheaper Disaster Recovery blocks and files



Dell EMC has announced Cloud Storage Services, a cheaper Disaster Recovery, that eliminates the need for a separate DR website. The service uses public cloud and an MSP intermediary instead.

The service is a two-step affair, where customers replicate data into a Managed Service Provider (MSP) service, which has a direct connection to a public cloud.

When the disaster strikes the site site, the calculation switches to public cloud and the computed instances stored there access the data on the arrays using a direct connection with a 3ms or lower link.

Cloud Storage Services supports PowerMax, Unity and Isilon on site. SC arrays are not supported.

Arrays without Direct Connect connection can up to a second or more to replicate data to public cloud, depending on the network bandwidth used.

Dell foresees that customers will typically replicate a subset of data to the MSP page so that the arrays there would be smaller than their local relatives.

This is similar to NetApp's 2012 Vintage NetApp Private Storage which "enables a NetApp FAS device to be placed in a data center – especially one where Amazon's Direct Connect operates – from where it will be available for" immediate use via iSCSI to and from their EC2 environment. ""

Cloud Storage Services supports four public cloud targets: VMware Cloud on AWS, AWS, Azure and GCP. The Dell EMC says the multi-cloud approach allows you to calculate instances in each cloud to access MSP arrays. It is not necessary to move data to these clouds or to pay for storage. Users only pay for the calculation in the cloud when it is to be used.

Customers running VMware environments can deploy a DR system using VMware Cloud on AWS as the secondary site. VMware Site Recovery Manager, along with original replication of the Dell EMC storage arrays, enables automation of DR operations.

It is a Cloud Storage Services datasheet.

Dell EMC Cloud Storage Services is available in the US and UK for VMware Cloud on AWS, AWS, Google Cloud Platform, and Microsoft Azure.
