New in This Release

The following features were added to Storage Center 7.3:

Advanced Restripe

Several enhancements have been made to the RAID restripe process to integrate and remove disks from a storage system.

One major feature is the ability for the storage system to offload data transfers to RAID for reduced restripe times. The storage system

also has improved targeting of data movement to reduce unnecessary effort. To provide accurate monitoring of RAID rebalances, the

Storage Manager Client and Unisphere interface contain an improved RAID rebalance progress interface.

Automatic Disk Placement

Automatic disk placement allows you to configure the default disk folder to use for newly-inserted drives.

CloudIQ Support

CloudIQ simplifies storage management by providing:

• Centralized monitoring across your environment.

• Proactive serviceability that informs you about issues before they impact your environment.

• A dashboard that aggregates key information such as system health scores, performance metrics, and current capacity and trends.

For more information about using CloudIQ to monitor Storage Centers, see the Storage Center CloudIQ Onboarding Quick-Start Guide

located on the Dell EMC Support site.

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 firmware.)

• 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.
