PRODUCT OVERVIEW

Dell EMC SC Series (formerly Compellent) arrays provide a unified platform for the ultimate in performance, adaptability and machine-driven efficiency. SC Series software delivers modern features that help you meet aggressive workload demands using the fewest drives necessary. With an open, future-ready design, SC Series storage integrates seamlessly with applications and infrastructure, enabling you to scale on a single platform and add capabilities without forklift upgrades. For more information on the SC Series, see here.

The Dell EMC SC Series driver manages Storage Center arrays through the Dell Storage Manager (DSM).
DSM connection settings and Storage Center options are defined in the cinder.conf file.

The Dell EMC SC Series volume driver interacts with pre-configured SC Series arrays and supports various operations, such as

• Create, delete, attach (map), and detach (unmap) volumes.
• Create, list, and delete volume snapshots.
• Create a volume from a snapshot.
• Copy an image to a volume.
• Copy a volume to an image.
• Clone a volume.
• Extend a volume.
• Create, delete, list and update a consistency group.
• Create, delete, and list consistency group snapshots.
• Manage an existing volume.
• Failover-host for replicated back ends.
• Create a replication using Live Volume.

Other features include

1. Extra spec options:
   Volume type extra specs can be used to enable a variety of Dell EMC SC Series options. Selecting Storage Profiles, Replay Profiles, enabling replication, replication options including Live Volume and Active Replay replication.
   Storage Profiles control how Storage Center manages volume data.
   For a given volume, the selected Storage Profile dictates which disk tier accepts initial writes, as well as how data progression moves data between tiers to balance performance and cost. Predefined Storage Profiles are the most effective way to manage data in Storage Center.

2. Dual DSM:
   It is possible to specify a secondary DSM to use in case the primary DSM fails.

3. Server type configuration
   This option allows one to set a default Server OS type to use when creating a server definition on the Dell EMC Storage Center.

4. Excluding a domain:
   This option excludes a Storage Center ISCSI fault domain from the ISCSI properties returned by the initialize_connection call. This only applies to the ISCSI driver.

5. Failback:
   The failover-host command is designed for the case where the primary system is not coming back. If it has been executed and the primary has been restored it is possible to attempt a failback.
