Release Notes

Conservation and Emergency Mode
The Conservation Mode threshold has been changed to 0.5 percent of the usable space in a storage system. The minimum amount of
usable space might range from 100 GB to 2 TB, depending on size of the storage system.
When a storage system enters Conservation Mode, the volume queue depth is limited to reduce the rate at which servers consume space.
Snapshots no longer expire automatically when a storage system is in Conservation or Emergency mode.
Conservation and Emergency mode messaging improvements have been added to Storage Manager and Unisphere. The storage system
sends alerts every day the system is in Conservation mode. The Storage Manager Client and Unisphere interface also display a
Conservation or Emergency mode banner that links to information about reducing space consumption.
Cross-Platform Replication
The following improvements have been made to cross-platform replication:
• Snapshot Management on PS Groups – Storage Center snapshots Time To Live (TTL) is monitored by the PS Group and snapshots are
automatically deleted according to schedule. (Requires PS Series version 10.0 rmware.)
• Cross-Platform Replication on a remote Data Collector – If the primary Data Collector is unavailable, a remote Data Collector can be
used for cross-platform replication.
Data Collector Management
The Data Collector management features in Storage Manager 2018 R1 have moved to the Unisphere Central web-based user interface.
When the Data Collector 2018 R1 software is installed on a Windows server, the Dell Storage Manager Data Collector shortcut is replaced
by the Dell EMC Unisphere Central shortcut.
Opening the Dell EMC Unisphere Central shortcut starts a web browser that displays the Unisphere Central web-based user interface. The
Data Collector management features are located in the Data Collector view of Unisphere Central.
NOTE
: Unisphere Central can also be accessed from a web browser on a computer that can communicate with the Data
Collector server.
Data-in-Place Migration
Data-in-Place Migration is a new licensed feature in Storage Center 7.3.2 that can be used to upgrade an SC4020 storage system to an
SC5020 or SC7020 storage system.
Direct Update
The Direct Update feature in Storage Manager 2018 R1.10 is available only when the Storage Manager Client is directly connected to a
storage system running Storage Center 6.6.
The Direct Update feature allows you to update a storage system running Storage Center 6.6 to a later supported version of Storage
Center.
