Release Notes

Data Center Bridging (DCB) Support

Storage Center 7.1 supports data center bridging (DCB) services.

Dell Storage Manager displays DCB information for supported I/O cards, such as switch names and features of the switch port that an

iSCSI port is plugged into. Dell Storage Manager also displays information about the Link Layer Discovery Protocol (LLDP), which is used

to help support DCB.

Data Progression Improvements

Storage Center includes changes to Data Progression that reduce the impact on Storage Center performance.

Data Progression runs daily at specified time and continues until all tasks are completed. If all the tasks are not completed, those tasks are

completed in the next Data Progression cycle.

NOTE:

Data Progression still follows the schedule set on the Storage Center.

Data Reduction

Data Reduction uses compression and deduplication to decrease the amount of disk space used by volume data. Compression reduces the

amount of space used by a volume by encoding data. Deduplication finds duplicate data in pages then removes the duplicate data,

conserving the disk space that would be used by additional copies. When deduplication is used, compression is also applied to a volume.

Drive Age Reporting

Storage Center 7.1 adds support for the Drive Age Reporting feature.

The age of each drive is displayed as Power On Time in Dell Storage Manager 2016 R2.

Federation Live Migrate

Storage Center 7.1 adds support for the Federation Live Migrate feature.

Federation Live Migrate allows for the online migration of a volume from one Storage Center to another Storage Center without downtime

or disruption to the host server.

NOTE:

Federation Live Migrate is supported on SC9000, SC8000, SC7020, and SC4020 storage systems, but it is not

supported on SCv2000 series storage systems.

IPv6 Support for Fault Domains and Pinging

Storage Center 7.1 supports IPv6 addresses in iSCSI fault domains as well as other IPv6 features.

• iSCSI fault domains can be created and modified to use ports with IPv6 addresses.

• Dell Storage Manager 2016 R2 can display multiple IPv6 addresses for each physical port, as well as multiple discovered gateway IPv6

addresses.

• Ports can be pinged using an IPv4 or IPv6 address.

NOTE:

Replications between Storage Center and PS Series groups do not support IPv6.

Live Volume with Auto Failover in Microsoft Server

Enviroments

Storage Center 7.1 adds support for the Live Volume with Auto Failover feature in Microsoft server environments.

Live Volume with Auto Failover is supported in Microsoft server environments including Windows Server 2012 and Windows Server 2012

R2. In addition, Live Volume with Auto Failover is supported on both Microsoft Hyper-V and Windows clustering environments including

Windows clustering on VMware hosts using physical mode raw device mappings (pRDMs).
