Release Notes

Disk Size Redundancy Level

4.0 TB or larger Dual redundancy is required when adding disks of this size to a new or existing page pool

T10-PI Support

Storage Center 7.1 adds support for T10 Protection Information (PI) capable drives.

T10 Protection Information is an end-to-end data integrity feature that protects against silent data corruption.

Volume QoS Profiles

Storage Center 7.1 supports Volume QoS Profiles.

When the Volume QoS Profiles feature is enabled, users can create and manage profiles for Quality of Service (QoS) settings using Dell

Storage Manager 2016 R2.

The volume QoS feature allows users to define an arbitrary quality of service for volumes by setting hard limits on volume IOPS or

throughput. Using the QoS Profiles feature, a user can apply QoS profiles to a single volume or group of volumes.

By default, Dell Storage Manager provides a single default profile which is used for all volumes. Users can create their own custom profiles

and apply them to volumes.

VMware Virtual Volumes Support

Storage Center 7.1 supports VMware Virtual Volumes (VVols) technology.

VMware VVols is a storage management and integration framework designed to deliver a more efficient operational model for attached

storage.

A key component of the VVols framework is the VASA 2.0 Provider included as part of Dell Storage Manager 2016 R2. VASA (vSphere

Storage APIs for Storage Awareness) is a software management interface between the vCenter server and storage systems. To enable

VVols operations between VMware vCenter Server and a Storage Center, the VASA Provider is registered with VMware vCenter server.

Storage Manager includes these user interface enhancements to support VVols:

• Addition of the Register VASA Provider option to the Register Server action.

• New wizards for defining and managing storage containers. A storage container is a pool of storage that is used in a VMware

environment in support of virtual volumes. A storage container corresponds to a VVol datastore in the vCenter interface.

• A new datastore type, VVOL, can be specified when creating datastores on a VMware vSphere host.

• Updated storage views to include VVol information.

See the Dell Storage Manager Administrator’s Guide and Dell Storage Manager Release Notes for information about VVols requirements

and recommendations.
