Feature Feature Description
Controller name in Storage Center

Added the controller name to Storage Center alerts to help customers identify the
storage system to which an alert applies.
Deduplication and Compression

I/O on the storage system, which increases the effectiveness of deduplication and
compression background operations.
Enhanced Disk Fault Management
(EDFM)
Enhanced the drive fault processing behavior to reduce the extremely low risk of drive
faults negatively impacting storage system performance.
General performance improvements Improved the performance of supported storage systems.
RAID and Distributed Spare

Resolved issues
The following high severity issues are resolved in this release:
Table 11. Issues resolved in Storage Center 7.5.1
Issue Functional area Description
SCOS-61427 Alerts, Logs, and
Reports
Storage Center might generate alerts about pagepools entering conservation
mode despite plenty of free space on the disks. This issue occurs when
the Threshold Allocation value is less than the Threshold Conservation value,
which prevents Add Space from running before the storage system enters
Conservation mode.
