Release Notes

Firmware Release Guidelines
Dell EMC Support: Product Management
Note: Customers should review maintenance release documentation to determine the priority of taking a
maintenance release for their specific environments and generally update their systems 1-2 times per year,
within the bounds of their business needs and practices.
A patch release may require individual controller restart after installation, but no downtime in dual-controller
systems. The patch releases provided to customers to resolve specific issues; are not maintained
releases. To receive ongoing support for a release (i.e. Super package updates), the expectation is that
customers will update to the next maintenance release containing the fix for their issue.
A super package release may require individual controller restart after installation, but no downtime in dual-
controller systems.
SC Series does not support downgrading of software to an earlier version.

2.2 Supported firmware releases
Dell EMC reserves the right to provide software maintenance for Replay Manager agents, management
software, operating system, and super package releases on previous releases as Dell EMC determines, in its
sole discretion. Dell EMC is under no obligation to provide any such maintenance.
2.2.1 Storage Center Operating System (SCOS)
Dell EMC’s firmware support goal is to provide maintenance support for the two (2) most recent releases.
Super package releases will be provided, if required, for up to two years after the general availability (GA) or
commercial release. Dell EMC strongly recommends that customers ensure they are running one of the two
supported release lines. During a technical support engagement, Dell EMC technical support may request
that a customer upgrade to one of the two supported release lines to resolve issues a customer may be
experiencing which were fixed in a supported release.
As an exception, Dell EMC Storage may, in its sole discretion, provide patches for an unsupported release as
conditions warrant.
