Cisco is urging customers to replace flawed memory sticks in some of its Unified Computing System (UCS) servers before they fail.
The problem is caused by a manufacturing error in 24 dual in-line memory modules (DIMM) that exhibit persistent correctable memory errors that if left in place could knock the servers offline. The problem is found in 16GB, 32GB, and 64GB memory DIMMs.
Cisco describes the flaws as manufacturing deviations that affect memory modules used to make up the DIMMs. All of the problem parts were manufactured during the middle-to-end of 2020, according to a Cisco alert.
