Cisco names Micron as supplier of SSDs that make Nexus and Firepower kit snooze

Cisco has named Micron as the supplier of solid-state disks that put themselves to sleep after 28,224 hours of operation. Switchzilla warned that flimsy firmware could fell some of its Nexus 9000 and 3000 devices back in February 2021, and last week issued Field Notices warning that some of its Firepower security appliances …

“A Micron data sheet [PDF] describes the device as a 2016-vintage 64GB drive built on 20nm MLC NAND Flash sporting a SATA interface and offering three million hours mean time to failure.

We mention that last figure as it is well short of the 28,224 hours after which the M500IT puts itself to sleep inside Cisco devices, perhaps suggesting that it is Cisco’s firmware and/or OS at fault rather than any mess made by Micron.”

Wrong way round, but if it’s something Cisco side then micron should release a public reminder to those embedding their hardware not to do whatever Cisco is doing.

Work arounds and a fix is well known, also some of that kit is approaching eol so should only be running another decade.

On the plus side, we can't buy this kit anyway.

Cisco has been problematically committed to JIT inventory for years now, leading to unnacceptable supply delays. Right now with the current supply chain messes, lead time on Firepower gear is over four months. So, in a sense, the problem has resolved itself.
